United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Idaho
–
Idaho is a state in the northwestern region of the United States. It borders the state of Montana to the east and northeast, Wyoming to the east, Nevada and Utah to the south, to the north, it shares a small portion of the Canadian border with the province of British Columbia. With a population of around 1.7 million people and an area of 83,569 square miles, Idaho is the 14th largest, the states capital and largest city is Boise. Idaho prior to European settlement was inhabited solely by Native American peoples, in the early 19th century, Idaho was considered part of the Oregon Country, an area disputed between the U. S. and the United Kingdom. Idaho was eventually admitted to the Union on July 3,1890, forming part of the Pacific Northwest, Idaho is divided into several distinct geographic and climatic regions. In the states north, the relatively isolated Idaho Panhandle is closely linked with Eastern Washington, the states south includes the Snake River Plain, while the south-east incorporates part of the Great Basin. Idaho is quite mountainous, and contains several stretches of the Rocky Mountains, additionally, around 38 percent of Idahos land is held by the United States Forest Service, the most of any state. Industries significant for the economy include manufacturing, agriculture, mining, forestry. Idahos agricultural sector supplies a number of different products, but the state is best known for its potato crop, the official state nickname is the Gem State, which references Idahos reputation for gemstones and, more broadly, its many wilderness areas. The exact origin of the remains a mystery. Willing later claimed that he had invented the name. Congress ultimately decided to name the area Colorado Territory when it was created in February 1861, thinking they would get a jump on the name, locals named a community in Colorado Idaho Springs. However, the name Idaho did not fall into obscurity, the same year Congress created Colorado Territory, a county called Idaho County was created in eastern Washington Territory. The county was named after a steamship named Idaho, which was launched on the Columbia River in 1860 and it is unclear whether the steamship was named before or after Willings claim was revealed. Regardless, a portion of Washington Territory, including Idaho County, was used to create Idaho Territory in 1863. Despite this lack of evidence for the origin of the name, the name Idaho may be derived from the Plains Apache word ídaahę́, which means enemy. The Comanches used this word to refer to the Idaho Territory, a 1956 Idaho history textbook says, Idaho is a Shoshoni Indian exclamation. The word consists of three parts, the first is Ee, which in English conveys the idea of coming down

Air National Guard
–
When Air National Guard units are used under the jurisdiction of the state governor they are fulfilling their militia role. However, if federalized by order of the President of the United States and they are jointly administered by the states and the National Guard Bureau, a joint bureau of the Army and Air Force that oversees the National Guard of the United States. The ANG of the territories of Guam and the Virgin Islands have no aircraft assigned, ANG units typically operate under Title 32 USC. However, when operating under Title 10 USC all ANG units are operationally-gained by an active duty USAF major command. ANG units of the Combat Air Forces based in the Continental United States, conversely, CONUS-based ANG units in the Mobility Air Forces, plus the Puerto Rico ANGs airlift wing and the Virgin Islands ANGs civil engineering squadron are gained by the Air Mobility Command. The vast majority of ANG units fall under either ACC or AMC, established under Title 10 and Title 32 of the U. S. S. When not in a status, the Air National Guard operates under their respective state. The exception to rule is the District of Columbia Air National Guard. Because both state Air National Guard and the Air National Guard of the United States relatively go hand-in-hand, Air National Guard of the United States units or members may be called up for federal active duty in times of Congressionally sanctioned war or national emergency. The United States Air National Guard has about 110,000 men and women in service, even traditional part-time air guardsmen, especially pilots, navigators/combat systems officers, air battle managers and enlisted aircrew, often serve 100 or more man-days annually. As such, the concept of Air National Guard service as representing only one weekend a month, the Georgia Air National Guard and the Kansas Air National Guard previously flew the B-1B Lancer prior to converting to the E-8 Joint STARS and KC-135R Stratotanker, respectively. In addition, the 131st Fighter Wing of the Missouri Air National Guard transitioned from flying the F-15C/D Eagle at St and these proposals were eventually overruled and cancelled by the U. S. Congress. As state militia units, the units in the Air National Guard are not in the normal United States Air Force chain of command and they are under the jurisdiction of the United States National Guard Bureau unless they are federalized by order of the President of the United States. Air National Guard units are trained and equipped by the United States Air Force, the state ANG units, depending on their mission, are operationally gained by a major command of the USAF if federalized. Air National Guard personnel are expected to adhere to the moral and physical standards as their full-time active duty Air Force. The same ranks and insignia of the U. S. Air Force are used by the Air National Guard, the Air National Guard also bestows a number of state awards for local services rendered in a service members home state or equivalent. The creation of the regiments was caused by the perceived need to defend the Bay Colony against American Indians. This organization formed the basis of subsequent colonial and, post-independence, state and this distinction accounts for why there are no National Guard components in the U. S. Navy, U. S. Marine Corps or U. S. Coast Guard

Idaho Air National Guard
–
The Idaho Air National Guard is the aerial force militia of the U. S. State of Idaho. It is, along with the Idaho Army National Guard, an element of the Idaho National Guard, as state militia units, the units in the Idaho Air National Guard are not in the normal United States Air Force chain of command. They are under the jurisdiction of the Governor of Idaho though the office of the Idaho Adjutant General unless they are federalized by order of the President of the United States. The Idaho Air National Guard is headquartered in Boise, and its commander is currently Brigadier General Michael A. Nolan, under the Total Force concept, Idaho Air National Guard units are considered to be Air Reserve Components of the United States Air Force. Idaho ANG units are trained and equipped by the Air Force and are gained by a Major Command of the USAF if federalized. State missions include disaster relief in times of earthquakes, hurricanes, floods and forest fires, search and rescue, protection of public services. These unit designations were allotted and transferred to various State National Guard bureaus to provide them unit designations to re-establish them as Air National Guard units, the Idaho Air National Guard was formed in large part by Lieutenant Colonel Thomas Lanphier. Serving in the Pacific Theater Fifth Air Force during World War II and he stood up the 190th Fighter Squadron receiving federal recognition on 13 October 1946. Most of Idahos early airmen were also World War II veterans, the 190th was formed with 23 officers and 44 enlisted airmen at a small building in downtown Boise. They had nothing, no buildings, no money or equipment, receiving F-51D Mustangs, the squadron moved to Gowen Field in 1947 and has been there ever since. The initial mission of the Idaho ANG was the air defense of the state, today, the Idaho ANG performs a worldwide ground-air support mission, along with a forward air controller training mission and support for active-duty USAF training missions. After the September 11th,2001 terrorist attacks on the United States, also, Idaho ANG units have been deployed overseas as part of Operation Enduring Freedom in Afghanistan and Operation Iraqi Freedom in Iraq as well as other locations as directed. As a result of the attack by the 190th A-10 aircraft, British Lance-Corporal of Horse Matty Hull was killed and five of his colleagues were injured, four seriously.

Boise Airport
–
Boise Airport is a joint civil-military airport three miles south of Boise in Ada County, Idaho, United States. The airport is operated by the city of Boise Department of Aviation and is overseen by an Airport Commission, Boise is a landing rights airfield requiring international general aviation flights to receive permission from a Customs and Border Protection officer before landing. The 124 FW operates the A-10 Thunderbolt II aircraft, the National Interagency Fire Center is based in the city of Boise and the Boise Airport is used for logistical support. The United States Forest Service also uses Boise Airport as a base for aerial firefighting air tankers during the wildfire season. Boise Airport had 1,487,764 enplaned passengers in 2015, growing from 1,378,352 passengers in 2014, BOI ranked 72nd in the nation in enplanements for 2015. In 1926 the first municipal airport in Boise named Booth Field was built on a bed where the Boise State University campus now stands. The first commercial flight in the United States passed through this airfield on April 26,1926. Varney Airlines began operating out of Boise in 1933, later merging with National Air Transport to become United Airlines. With United Airlines able to trace its roots to Varney, United is recognized as the airline that has operated the longest out of Boise,83 years as of 2009, the airfield also played host to Charles Lindberghs Spirit of St. Louis on September 4,1927. The current airport has its origins in 1936 when Boise began buying and leasing land for the airport, by 1938 Boise had the longest runway in the United States,8,800 feet. The steel hangar for Varney Airlines was moved to the present field in 1939, as aircraft grew the hangar was no longer big enough and was converted into a passenger terminal. It was part of the terminal facility until the completion of a new terminal in 2004. During World War II the Army Air Corps, later Army Air Forces, leased the field for use as a base for B-17 Flying Fortress. More than 6,000 men were stationed there during the war, the field was named Gowen Field in 1941 on July 23, after 1st Lt Paul R. Gowen. Born and raised in Caldwell, he attended the University of Idaho for two years, then obtained an appointment to West Point in 1929, and graduated ninth in his class in 1933. While piloting a twin-engine B-10 bomber in the Army Air Corps, the right engine failed shortly after take-off from Albrook Field, near Panama City. The other two members, navigator and radio operator, survived and crawled from the wreckage with burns. After the war the part of the used by the Army Air Forces was returned to the city

Operation Southern Watch
–
Operation Southern Watch was an air-centric military operation conducted by the United States Department of Defense from Summer 1992 to Spring 2003. Nothing in the resolution spelled out the Iraqi no-fly zones or Operation Southern Watch, military forces from Saudi Arabia, the United States, the United Kingdom, and France participated in Operation Southern Watch. An intensification was noted prior to the 2003 invasion of Iraq and it is now known that this increased activity occurred during an operation known as Operation Southern Focus. At first, Iraqi forces did not attack Coalition aircraft, later in the day, several Iraqi fighters dodged back and forth across the 32nd parallel, staying out of missile range of American fighters. However, an Iraqi MiG-25 crossed too far and was trapped inside the 32nd parallel by a flight of USAF F-16 Falcons of the 33rd Fighter Squadron, after intelligence verified the aircraft was hostile, the fighter pilot received clearance to fire. The lead plane piloted by then-Lieutenant Colonel Gary North, USAF and this was the first combat kill by an F-16 in USAF service, and the first combat kill using the AIM-120 AMRAAM missile. On 17 January 1993, a USAF F-16C destroyed an Iraqi MiG-23 Flogger with an AMRAAM missile for the second USAF aerial victory, on 7 January 1993, Iraq agreed to American, British, and French demands to withdraw their surface-to-air missiles from below the 32nd parallel. However, they did not remove all of them, and U. S. President George H. W. Bush ordered U. S. aircraft to bomb the remaining missile sites. On 13 January, more than 100 American, British, and French aircraft attacked Iraqi missile sites near Nasiriyah, Samawah, Najaf, around half the Iraqi sites south of the 32nd parallel were hit. On 29 June, a USAF F-4G Phantom II destroyed an Iraqi radar which had illuminated it, the first nine months of 1994 were quiet, and the USAF began to withdraw forces from the region. Saddam later withdrew the Iraqi Republican Guard out of the Kuwati border due to massive American military buildup and this served to increase Coalition resolve to enforce the no-fly zones and contain Iraqi aggression. On 25 June 1996, terrorists bombed the U. S. base at Khobar Towers in Dhahran, the attack killing 19 American airmen and injured an additional 372 people. In August 1996, Iraqi forces invaded the Kurdish regions of northern Iraq, as a result, the no-fly zone was extended north to the 33rd parallel. This marked renewed conflict with Iraqi air defenses and several more radars were destroyed by F-16 fighters, on 15 December 1998, France suspended participation in the no-fly zones, arguing that they had been maintained for too long and were ineffective. On 16 December, U. S. President Bill Clinton ordered execution of Operation Desert Fox and this resulted in an increased level of combat in the no-fly zones which lasted until 2003. On 30 December 1998, Iraqi SA-6 missile sites fired 6 to 8 surface-to-air missiles at American military aircraft, USAF F-16s responded by bombing the sites. On 5 January 1999, four Iraqi MiG-25s crossed into the southern no-fly zone, the American fighters fired a total of six missiles at the Iraqi aircraft, but they were able to evade them all and escape back to the north. Over the same period, American aircraft had attacked Iraqi targets on 73 occasions

Iraq War
–
The Iraq War was a protracted armed conflict that began in 2003 with the invasion of Iraq by a United States-led coalition that toppled the government of Saddam Hussein. The conflict continued for much of the decade as an insurgency emerged to oppose the occupying forces. An estimated 151,000 to 600,000 or more Iraqis were killed in the first 3–4 years of conflict and it became re-involved in 2014 at the head of a new coalition, the insurgency and many dimensions of the civil armed conflict continue. The invasion began on 20 March 2003, with the U. S. joined by the United Kingdom and several allies, launching a shock. Iraqi forces were overwhelmed as U. S. forces swept through the country. The invasion led to the collapse of the Baathist government, President Hussein was captured during Operation Red Dawn in December of that same year, the United States responded with a troop surge in 2007. The winding down of U. S. involvement in Iraq accelerated under President Barack Obama, the U. S. formally withdrew all combat troops from Iraq by December 2011. Select U. S. officials accused Saddam of harboring and supporting al-Qaeda, while others cited the desire to end a repressive dictatorship, after the invasion, no substantial evidence was found to verify the initial claims about WMDs. The rationale and misrepresentation of pre-war intelligence faced heavy criticism within the U. S. in the aftermath of the invasion, Iraq held multi-party elections in 2005. Nouri al-Maliki became Prime Minister in 2006 and remained in office until 2014, the al-Maliki government enacted policies that were widely seen as having the effect of alienating the countrys Sunni minority and worsening sectarian tensions. The Iraq War caused hundreds of thousands of civilian, and thousands of military casualties, the majority of casualties occurred as a result of the insurgency and civil conflicts between 2004 and 2007. A1990 Frontline report on The arming of Iraq said, Officially, most Western nations participated in an arms embargo against Iraq during the 1980s. Western companies, primarily in Germany and Great Britain, but also in the United States, sold Iraq the key technology for its chemical, missile, any Western governments seemed remarkably indifferent, if not enthusiastic, about those deals. N Washington, the government consistently followed a policy which allowed and perhaps encouraged the growth of Saddam Husseins arsenal. The Western arming of Iraq took place in the context of the Iran-Iraq War, prior to September 2002, the CIA was the George W. Bush administrations main provider of intelligence on Iraq. The agency was out to disprove linkage between Iraq and terrorism the Pentagon adviser told me, the U. N. had prohibited Iraq from developing or possessing such weapons after the Gulf War and required Iraq to permit inspections confirming compliance. This was confirmed by The New York Times and The Wall Street Journal, during 2002, Bush repeatedly warned of military action against Iraq unless inspections were allowed to progress unfettered. In accordance with U. N. Security Council Resolution 1441, Iraq agreed to new inspections under United Nations Monitoring, as part of its weapons inspection obligations, Iraq was required to supply a full declaration of its current weapons capabilities and manufacturing

Lanphier was promoted to captain in March 1943, the next month he destroyed three A6M Zeros over Cape Esperance on April 7,1943. By the end of his tour, he flew 97 combat missions out of Guadalcanal in P-39s, following World War II, he was one of the founding members of the Idaho Air National Guard, eventually retiring as a Colonel. The mission was a success with both of the Betty bombers being destroyed, officially, the after-action report gave Captain Lanphier and his wingman First Lieutenant Rex T. Barber each half-credit for the kill, promoted to lieutenant colonel in February 1945, Lanphier served as director of operations of the 72nd Fighter Wing of the Second Air Force until late 1945. Leaving active duty following the war, he was promoted to colonel in the Air Force Reserves in 1950.

124th Fighter Wing
–
The 124th Fighter Wing is a unit of the Idaho Air National Guard, stationed at Gowen Field Air National Guard Base, Boise, Idaho. If activated to service, the Wing is gained by the United States Air Force Air Combat Command. S. The 190th FIS becoming the flying squadron. Other squadrons assigned into the group were the 124th Headquarters, 124th Material Squadron, 124th Combat Support Squadron, also in 1955, the F-86A day interceptors were replaced by the F-94A Starfire all-weather interceptor. The 190th changed aircraft four times over the next 23 years to fly the F-89C Scorpion, F-86L Sabre Interceptor. In 1958, the 124th implemented the ADC Runway Alert Program, in which interceptors of the 190th FIS were committed to a runway alert. In 1968 Air Defense Command was re-designated as Aerospace Defense Command, in November 1975, the 124th Fighter-Interceptor Group was transferred from Air Defense Command to Tactical Air Command. It was re-equipped by TAC with the RF-4C Phantom II Mach 2 high speed reconnaissance aircraft, many of these planes were veterans of combat in Vietnam. F-4 Phantom jets would eventually spend 20 years on Gowen Field, the unarmed RF-4C carried high resolution cameras and electronic sensors, which soon proved their worth to thousands of people in Idaho. Aerial photographs were taken immediately after the 1983 Borah Peak earthquake near Challis. The Challis-Mackay region experienced rather thorough damage, with 11 commercial buildings and 39 homes with major damage, while another 200 houses were damaged, the reconnaissance photos helped emergency response crews locate and evaluate the damage. The RF-4C was still in service at the time of the 1991 Gulf War, Operation Desert Storm, following the end of Desert Storm, all of the remaining RF-4Cs were withdrawn from USAF service. In 1991, Idaho’s Air Guard changed aircraft and mission again, the Idaho ANG was to be the only ANG unit to operate the F-4G. The F-4G was designed as an anti-Surface to Air Missile aircraft to jam, the F-4Gs were received from the 37th Tactical Fighter Wing at George AFB, California as part of the closure of George AFB. The squadron was re-designated as the 190th Fighter Squadron with the changeover of its parent 124th to the Air Force Objective Wing organization, in 1992, the 124th Fighter Group became part of the new Air Combat Command. In April 1993 the squadrons Wild Weasel jets were sent to Southwest Asia to support Operation Southern Watch, twice 190th airmen were challenged by illegal Iraqi air defense radar near Basra. The threats were answered — and silenced — with AGM-88 High-Speed Anti-Radiation Missile anti-radiation missiles, from 1993 to 1995 there were a total of four deployments to the Gulf. The last such deployment returned to Boise in December 1995, Idaho’s airmen served longer in Southwest Asia than any other flying unit in the Air National Guard

Fairchild Republic A-10 Thunderbolt II
–
The Fairchild Republic A-10 Thunderbolt II is a single-seat, twin turbofan engine, straight wing jet aircraft developed by Fairchild-Republic for the United States Air Force. Commonly referred to by its nicknames Warthog or Hog, its name comes from the Republic P-47 Thunderbolt. The A-10 was designed for air support of friendly ground troops, engaging armored vehicles and tanks. It entered service in 1976 and is the only aircraft that has served in the USAF that was designed solely for CAS. Its secondary mission is to forward air controller – airborne support. Aircraft used primarily in this role are designated OA-10, the A-10 was intended to improve on the performance of the A-1 Skyraider and its poor firepower. The A-10 was designed around the 30 mm GAU-8 Avenger rotary cannon and its short takeoff and landing capability permits operation from airstrips close to the front lines, and its simple design enables maintenance with minimal facilities. The A-10 served in the Gulf War, the American intervention against Iraqs invasion of Kuwait, the A-10 also participated in other conflicts such as Operation Urgent Fury in Grenada, the Balkans, Afghanistan, Iraq, and against ISIL in the Middle East. The A-10A single-seat variant was the version produced, though one pre-production airframe was modified into the YA-10B twin-seat prototype to test an all-weather night capable version. In 2005, a program was started to upgrade remaining A-10A aircraft to the A-10C configuration with modern avionics for use of precision weaponry. The U. S. Air Force had stated the F-35 would replace the A-10 as it entered service, but this remains highly contentious within the Air Force and in political circles. With a variety of upgrades and wing replacements, the A-10s service life may be extended to 2040, post-World War II development of conventionally armed attack aircraft in the United States had stagnated. Design efforts for tactical aircraft focused on the delivery of nuclear weapons using high-speed designs like the F-101 Voodoo, designs concentrating on conventional weapons had been largely ignored, leaving their entry into the Vietnam War led by the Korean War-era Douglas A-1 Skyraider. While a capable aircraft for its era, with a large payload and long loiter times. The U. S. Air Force and Marine Corps lost 266 A-1s in action in Vietnam, the A-1 Skyraider also had poor firepower. The lack of conventional attack capability prompted calls for a specialized attack aircraft. The former became the Tactical Fighter Experimental, or TFX, which emerged as the F-111 and it was also expensive to buy and operate, with a flyaway cost of $2 million in FY1965, and operational costs over $900 per hour. After a broad review of its force structure, the U. S. Air Force decided to adopt a low-cost aircraft to supplement the F-4

The 142nd Fighter Wing is a unit of the Oregon Air National Guard, stationed at Portland Air National Guard Base, Oregon. As a state unit, the 142nd Fighter Wing is not in the normal United States Air Force chain of command. It is under the jurisdiction of the Oregon Air National Guard unless it is federalized by order of the president of the United States, if activated to federal service, the wing is gained by the United States Air Force Air Combat Command. The 123rd Fighter Squadron assigned to the wings 142nd Operations Group, is a descendant organization of 123rd Observation Squadron and it is one of the 29 original National Guard Observation Squadrons of the United States Army National Guard formed before World War II. Began operations, using P-47s, by making a sweep over France. Flew fighter- sweep, dive-bombing, and escort missions prior to the invasion of the continent, attacked railroads, trains, vehicles, gun emplacements, and buildings in France during the invasion of 6 June 1944. Patrolled beachhead areas and continued its assaults against the enemy during the remainder of the Normandy campaign, participated in the aerial barrage that prepared the way for the Allied breakthrough at St Lo on 25 July, and supported the subsequent drive across northern France. Conducted operations that supported Allied ground action in the Battle of the Bulge, returned to the US, October and November 1945 and inactivated. The wartime 371st Fighter Group was re-activated and re-designated as the 142nd Fighter Group and it was organized at Portland Municipal Airport, Oregon, and was extended federal recognition on 30 August 1946 by the National Guard Bureau. The 142nd Fighter Group was bestowed the history, honors, the groups 123rd Fighter Squadron was equipped with P-51D Mustangs and was assigned to the Fourth Air Force, Air Defense Command. The group was federalized and brought to duty on 2 March 1951. It was assigned to the Air Defense Command Western Air Defense Force and it was then reassigned to the federalized Washington ANG 142nd Fighter-Interceptor Wing on 11 April and moved to OHare International Airport, Chicago, Illinois, by 1 May 1951. Re-designated 142nd Fighter-Interceptor Group on 1 May 1951, at OHare, the 142nd Fighter Group controlled the 62nd Fighter-Interceptor Squadron, flying F-86A Sabre day interceptors. The group was inactivated on 6 February 1952, being replaced by the 4706th Air Defense Wing, re-formed as the 142nd Fighter-Interceptor Group, flying F-86F Sabre day interceptor aircraft. It resumed its mission of the air defense of Oregon. Was upgraded by ADC in 1955 to the dedicated F-94A Starfire all-weather interceptor, with this new aircraft, the mission of the 123rd Fighter-Interceptor Squadron changed from day interceptor to day and night all-weather interceptor. In 1957 the 123rd again upgraded to the improved F-89J Scorpion then in 1966 to the supersonic F-102A Delta Dagger. In the summer of 1958, the 142nd implemented the ADC Runway Alert Program, the runway alert continues to this day

Cargo services offered at the airport more than 100,000 square feet of warehouse/office space and 1,000,000 square feet of apron space. The airport is designated a Foreign Trade Zone, because of its position on the Eastern Seaboard, cargo transit via RIC is on the rise. Goods shipped out of the metropolitan Richmond area can reach 68% of the U. S. population within 24 hours,2016 was a record breaking year for RIC. The most western flight ever from RIC started on United Airlines, and Delta begun serving Richmond with larger aircraft on its 7 routes (planes were Boeing 757, Boeing 737, E170, and CRJ900. American Airlines, recently merged with US Airways started more flights to PHL, ORD, LGA, Jet Blue started 3 more daily flights to ORL. Two new airlines were welcomed into RIC, Allegiant, and One Jet, Piedmont Airlines will open up a hub in RIC,5 jets are based in RIC doing daily flights to PHL, and LGA. Piedmont did a 2 million dollar renovation of one of the hangars at RIC, the airport was dedicated as Richard Evelyn Byrd Flying Field in 1927 in honor of aviator Richard E. Byrd, brother of then Gov. Harry F. Byrd. Charles Lindbergh attended the dedication ceremony, although the facility was in Henrico County, Richmond Mayor John Fulmer Bright was instrumental in the creation of Byrd Field, which was initially owned by the City of Richmond. It was renamed Richard E. Byrd Airport in 1950, the current president and CEO of the airport is Jon Mathiasen. A terminal building designed by Marcellus Wright and Son was completed in 1950 and it was expanded from 1968 to 1970, which included the current passenger concourses. The April 1957 Official Airline Guide shows 43 weekday departures,22 on Eastern,10 Piedmont,5 American,4 National, in 2007, the airport served 3,634,544 passengers, a record for the airport, a 10. 3% increase over 2006

Squadron (aviation)
–
In most armed forces, two or more squadrons will form a group or a wing. Some air forces use the term squadrons for non-flying ground units. In contrast to United States Air Force units where flying squadrons are separate from supporting administrative and aircraft maintenance squadrons, in United States Marine Corps Aviation the nomenclature squadron is also used to designate all battalion-equivalent, aviation support organizations. These squadrons include, wing headquarters, tactical air command, air control, air support, aviation logistics, wing support, exceptions are USN helicopter mine countrmeasures squadrons, USMC composite medium tilt-rotor squadrons, heavy helicopter and light/attack helicopter squadrons, and Marine attack squadrons. Although part of U. S. naval aviation, United States Coast Guard aviation units are centered on an air station versus a squadron or group/wing organizational structure, the one exception to this is the Coast Guards Helicopter Interdiction Squadron, which is engaged primarily in counter-narcotics interdiction operations. In U. S. Army Aviation, flying units may be organized in battalions or squadrons reporting to an aviation brigade, an escadron is the equivalent unit in Frances Armée de lAir. It is normally subdivided into escadrilles of eight aircraft, in the Air Training Corps of the United Kingdom and many Commonwealth nations, a Squadron is a group of cadets who parade regularly. In the U. S. Civil Air Patrol, a squadron is the administrative unit. In the Swedish Air Force a helicopter squadron is a detachment from the Helicopter Wing

Republic P-47 Thunderbolt
–
The Republic P-47 Thunderbolt was a World War II era fighter aircraft produced by the United States between 1941–1945. Its primary armament was eight. 50-caliber machine guns and in the fighter-bomber ground-attack role it could carry five-inch rockets or a load of 2,500 pounds. When fully loaded the P-47 weighed up to eight tons making it one of the heaviest fighters of the war. The P-47 was designed around the powerful Pratt & Whitney R-2800 Double Wasp engine which was used by two U. S. Navy fighters, the Grumman F6F Hellcat and the Vought F4U Corsair. The Thunderbolt was effective as a short-to-medium range escort fighter in high-altitude air-to-air combat, the P-47 was one of the main United States Army Air Forces fighters of World War II, and served with Allied air forces including France, Britain, and Russia. Mexican and Brazilian squadrons fighting alongside the U. S. were equipped with the P-47, the armored cockpit was relatively roomy and comfortable, offering good visibility. A modern-day U. S. ground-attack aircraft, the Fairchild Republic A-10 Thunderbolt II, both had fled from their homeland to escape the Bolsheviks. In 1939, Republic Aviation designed the AP-4 demonstrator powered by a Pratt & Whitney R-1830 radial engine with a belly-mounted turbocharger. While the resulting Republic P-43 Lancer was in limited production, Republic had been working on an improved P-44 Rocket with a powerful engine. The latter was an aircraft powered by the Allison V-1710 liquid-cooled V-12 engine. The United States Army Air Corps backed the project and gave it the designation XP-47, as the war in Europe escalated in spring 1940, Republic and the USAAC concluded that the XP-44 and the XP-47 were inferior to the Luftwaffe fighters. Republic unsuccessfully attempted to improve the design, proposing the XP-47A, kartveli then designed a much larger fighter, which was offered to the USAAC in June 1940. The Air Corps ordered a prototype in September, to be designated the XP-47B, the XP-47A, which had little in common with the new design, was abandoned. The XP-47B was of construction with elliptical wings, with a straight leading edge that was slightly swept back. The air-conditioned cockpit was roomy and the seat was comfortable—like a lounge chair. Main and auxiliary self-sealing fuel tanks were placed under the cockpit, the cowling admitted cooling air for the engine, left and right oil coolers, and the turbosupercharger intercooler system. At full power, the pipes glowed red at their forward ends, the complicated turbosupercharger system with its ductwork gave the XP-47B a deep fuselage, and the wings had to be mounted in a relatively high position. This was problematic since long-legged main landing gear struts were needed to provide clearance for the enormous propeller

First Air Force
–
The First Air Force is a numbered air force of the United States Air Force Air Combat Command. It is headquartered at Tyndall Air Force Base, Florida and its primary mission is the air defense of the Contiguous United States, United States Virgin Islands and Puerto Rico. Its mission lineage can be traced to the Air Defense Command, during the war, its primary mission became the organization and training of combat units prior to their deployment to the overseas combat air forces. First Air Force is commanded by Lieutenant General R. Scott Williams and its Command Chief Master Sergeant is Chief Master Sgt. The command has responsibility for ensuring the air sovereignty and air defense of the Contiguous United States, United States Virgin Islands. As the CONUS Region for NORAD, the bi-national North American Aerospace Defense Command, 1AF is also the designated air component for the United States Northern Command. USNORTHCOMs area of responsibility includes the continental United States, Alaska, Canada and Mexico, the command is unique in both its mission and composition. First Air Force has been an Air Combat Command organization since 1 June 1992 and its subordinate units are located throughout the continental United States. It was redesignated First Air Force on 9 April 1941 with a mission for the defense of the Northeast, AAFSC would eventually expand that mission to the Gulf of Mexico and Caribbean until the antisubmarine mission was taken over completely by the Navy in mid-1943. The First Air Force became predominantly a fighter OTU and RTU organization, most P-47 Thunderbolt fighter groups were trained by I Fighter Command, along with P-39/P-63 Airacobra groups, C-47 Skytrain and later C-46 Commando groups by I Troop Carrier Command. Air Defense Wings were also organized for the metropolitan areas along the northeast coast. By 1944 the likelihood of an air attack along the eastern seaboard was remote, and these air defense wings were reduced to paper units. By 1944, the vast majority of the USAAF was engaged in operations in various parts of the world, such as the Eighth Air Force in Europe. First Air Force Headquarters was located at Fort Slocum, New York, the command was originally assigned the region of the New England states, along with New York and New Jersey. The command was inactivated on 23 June 1958 for budgetary reasons, First Air Force was reactivated at Stewart Air Force Base, Newburgh, N. Y. on 20 January 1966 due to the inactivation of the ADC Air Defense Sectors. First Air Force assumed responsibility for the ADC 21st, 33d, 34th, 35th and it also was responsible for the air defense of Greenland, Iceland and parts of Canada. By July 1968, First Air Force had again assumed responsibility for the air defense of the eastern seaboard. On 16 January 1968 Air Defense Command was re-designated Aerospace Defense Command as part of a restructuring of USAF air defense forces, ADCOM reassigned the units under the inactivated First Air Force were reassigned primarily to the 20th, 21st or 23d Air Divisions

United States Air Forces Central Command
–
United States Air Forces Central Command is a Named Air Force of the United States Air Force headquartered at Shaw Air Force Base, South Carolina. During the Cold War, it was one of two Numbered Air Forces of Tactical Air Command and it has fought in the 1991 Gulf War, War in Afghanistan, the Iraq War, as well as various engagements within USCENTCOM. United States Air Forces Central is the descendant organization of Ninth Air Force. AFCENT was formed as the United States Central Command Air Forces under Tactical Air Command, CENTAF initially consisted of designated United States Air Force elements of the Rapid Deployment Joint Task Force which was inactivated and reformed as USCENTCOM in 1983. On 1 March 2008 USCENTAF was redesignated USAFCENT and it shared its commander with Ninth Air Force until August 2009. Ninth Air Force was formally re designated USAFCENT on 5 August 2009, a new Ninth Air Force was established that date for command and control of CONUS-based Air Combat Command units formerly assigned to the previous Ninth Air Force. It is planned that they return to a shared commander after the United States completes its current wars. During World War II, the air forces of the United States Army Air Forces came to be classified as strategic or tactical. In June 1942, the German Afrika Korps advance in North Africa forced the British Eighth Army to retreat towards Egypt putting British Middle East Command at risk, harry A. Halverson, commanding twenty-three B-24D Liberator heavy bombers and a hand-picked crews, decided to move to Egypt. HALPRO was quickly diverted from its mission to a new one—interdictory raids from airfields in Egypt against shipping. On 28 June 1942, Major General Lewis H Brereton arrived at Cairo to command the U. S. Army Middle East Air Force, USAMEAF comprised the Halverson Detachment, Breretons detachment, and the Air Section of US Military North African Mission. Several USAAF units were sent to join USAMEAF during next weeks in the destruction of Rommels Afrika Korps by support to troops and secure sea. Col. Patrick W. Subsequent negotiations carried the point with the British, on 12 October a small staff moved into Grey Pillars, RAF headquarters at Cairo, and thenceforth USAMEAFs bombers operated only under the strategic direction of the British. After initially resisting the attack, Field Marshal Erwin Rommel decided he no longer had the resources to hold his line, Allied victory in the Second Battle of Alamein was accomplished. Ninth Air Force had been first constituted as V Air Support Command, part of Air Force Combat Command, at Bowman Field, Kentucky on 11 September 1941. It was reassigned to Bolling Field, Washington, D. C. on 22 July and transferred without personnel or equipment to Cairo, Egypt on 12 November 1942. The Ninth Air Force mission comprised, Gain air superiority, Deny the enemy the ability to replenish or replace losses, and Offer ground forces close support in North-East Africa. On 12 November 1942, the US Army Middle East Air Force was dissolved and replaced by HQ Ninth Air Force, commanded by Lieutenant General Lewis H. Brereton

RAF Bisterne
–
RAF Bisterne is a former Royal Air Force Advanced Landing Ground in Hampshire, England. The airfield is located in the hamlet of Bisterne approximately 2 miles south of Ringwood and it was used by the United States Army Air Force as a fighter airfield. It was closed late in the summer of 1944, today the airfield is a mixture of agricultural fields with no recognizable remains. Bisterne was known as USAAF Station AAF-415 for security reasons by the USAAF during the war and its USAAF Station Code was BS. On 7 March 1944 the 371st Fighter Group arrived, equipped with Republic P-47 Thunderbolts, the 347th FG arrived from Richmond AAF Virginia. It is only that by comparing the local roads in the area.

Operation Overlord
–
Operation Overlord was the code name for the Battle of Normandy, the Allied operation that launched the successful invasion of German-occupied Western Europe during World War II. The operation was launched on 6 June 1944 with the Normandy landings, a 1, 200-plane airborne assault preceded an amphibious assault involving more than 5,000 vessels. Nearly 160,000 troops crossed the English Channel on 6 June, the decision to undertake a cross-channel invasion in 1944 was taken at the Trident Conference in Washington in May 1943. The coast of Normandy was chosen as the site of the invasion, with the Americans assigned to land at sectors codenamed Utah and Omaha, the British at Sword and Gold, and the Canadians at Juno. In the months leading up to the invasion, the Allies conducted a military deception, Operation Bodyguard. This misled the Germans as to the date and location of the main Allied landings, Adolf Hitler placed German Field Marshal Erwin Rommel in charge of developing fortifications all along the Atlantic Wall in anticipation of an invasion. A failed counterattack by German forces on 8 August left 50,000 soldiers of the 7th Army trapped in the Falaise pocket, the Allies launched an invasion of southern France on 15 August, and the Liberation of Paris followed on 25 August. German forces retreated across the Seine on 30 August 1944, marking the close of Operation Overlord, in June 1940, Germanys leader Adolf Hitler had triumphed in what he called the most famous victory in history—the fall of France. The defending British Expeditionary Force, trapped along the northern coast of France, was able to evacuate over 338,000 troops to England in the Dunkirk evacuation. After the Germans invaded the Soviet Union in June 1941, Soviet leader Joseph Stalin began pressing for the creation of a front in Western Europe. Two tentative plans code-named Operation Roundup and Operation Sledgehammer were put forward for 1942–43, instead, the Allies launched the invasion of French North Africa in November 1942, the invasion of Sicily in July 1943, and invaded Italy in September. These operations provided the troops with valuable experience in amphibious warfare, the decision to undertake a cross-channel invasion within the next year was taken at the Trident Conference in Washington in May 1943. Churchill favoured making the main Allied thrust into Germany from the Mediterranean theatre, but was over-ruled by his American allies, British Lieutenant-General Frederick E. Morgan was appointed Chief of Staff, Supreme Allied Commander, to begin detailed planning. The initial plans were constrained by the number of landing craft, most of which were already committed in the Mediterranean. In part because of lessons learned in the Dieppe Raid of 19 August 1942, the failure at Dieppe also highlighted the need for adequate artillery and air support, particularly close air support, and specialised ships able to travel extremely close to shore. Morgan considered four sites for the landings, Brittany, the Cotentin Peninsula, Normandy, as Brittany and Cotentin are peninsulas, it would have been possible for the Germans to cut off the Allied advance at a relatively narrow isthmus, so these sites were rejected. The Pas de Calais is the closest point in continental Europe to Britain and was the location of sites for V-1 and V-2 rockets. The Germans considered it to be the most likely initial landing zone, Normandy was hence chosen as the landing site

Dive bomber
–
A dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bombs trajectory and allows the pilot to keep visual contact throughout the bomb run and this allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even en-masse. A dive bomber dives at an angle, normally between 45 and 90 degrees, and thus requires an abrupt pull-up after dropping its bombs. This puts great strains on both pilot and aircraft and it demands an aircraft of strong construction, with some means to slow its dive. This limited the class to light bomber designs with ordnance loads in the range of 1,000 lb although there were larger examples. The SBD Dauntless helped win the Battle of Midway, was instrumental in the victory at the Battle of the Coral Sea, a second and simpler technique is to bomb from a shallow dive angle, sometimes referred to as glide bombing. This reduces the accuracy, but still allows line of sight to the target during the bomb run, the Junkers Ju 88 and Petlyakov Pe-2 were widely used in this role. The Heinkel He 177 is often mentioned as having its development upset by the demand that it be able to dive bomb, the phrase glide bombing should not be confused with the term glide bomb, where the bomb glides towards its target while the aircraft remains in level flight. Attachments for this type of bombing were fitted to the Norden bombsight, Dive bombing was most widely used before and during World War II, its use declined during the war, when its vulnerability to enemy fighters became apparent. Most tactical aircraft today allow bombing in shallow dives to keep the target visible, when released from an aircraft, a bomb carries with it the aircrafts velocity. In the case of a bomber flying horizontally, the bomb will only be travelling forward. This forward motion is opposed by the drag of the air, additionally, gravity accelerates the bomb downward. The combination of two forces, drag and gravity, results in a complex pseudo-parabolic trajectory. The distance that the bomb moves forward while it falls is known as its range, if the range for a given set of conditions is calculated, simple trigonometry can be used to find the angle between the aircraft and the target. By setting the bombsight to this angle, the aircraft can time the drop of its bombs at the instant when the target is lined up in the sight. This was only effective for area bombing, however, since the path of the bomb is only roughly estimated. Large formations could drop bombs on an area hoping to hit a target, but there was no guarantee of success. The advantage to this approach, however, was that it is easy to build such an aircraft and fly it at high altitude, the horizontal bomber was thus ill-suited for tactical bombing, particularly in close support

Escort fighter
–
The escort fighter was a World War II concept for a fighter aircraft designed to escort bombers to and from their targets. An escort fighter needed range long enough to reach the target, loiter over it for the duration of the raid to defend the bombers, a number of twin-engined heavy fighters with high fuel capacity were designed for escort duties before World War II. Such heavy fighters largely failed in their intended escort role during the war, as the war progressed, longer-range fighter designs and the use of drop tanks allowed single-engined fighters to perform escort duties. In the post-war era the introduction of jet engines and their inherent short range escort fighters very difficult to build. The related concept of a penetration fighter emerged briefly in the 1950s and again in the 1960s, during the Battle of Britain, the Luftwaffe used Messerschmitt Bf 109s and Bf 110s based in France as escort fighter-bombers. Flying with the Heinkel He 111 and Junkers Ju 88 medium bombers, the U. S. Army Air Forces precision strategic bombing campaign against German industries was only possible during the day. At first, this was not seen as an issue, the Forces Boeing B-17 Flying Fortress, close formations of them were planned, creating a crossfire of.50 caliber machine-guns that would fend off the enemy with no need for a fighter escort. Hitting a fast-moving fighter with guns in a turret proved extremely difficult, USAAF bomber losses gradually increased, and experimental gunships like the YB-40 did nothing to reduce them. It was not until the introduction of the Lockheed P-38 Lightning, able to carry large Lockheed-designed drop tanks, the fighters were able to escort the bombers for much of their missions. The first Allied fighters over Berlin were 55th Fighter Group P-38s on March 3,1944, when the Merlin-powered North American P-51 Mustang was introduced, with a laminar-flow wing for efficiency, the final escort fighter development of the war was complete. The successes of the P-47N and P-51 gave the impression that the fighter was a concept worth continuing after the end of the war. A new concept, the XF-85 Goblin microfighter, planned to act as a fighter for the Convair B-36, was tested with a B-29 Superfortress. Later the FICON project attempted a solution, docking jet fighters with heavy bombers via a trapeze mechanism or their wingtips. In Korea, the F-80 Shooting Star and later the F-86 Sabre escorted B-29 heavy bombers, with the development of guided missiles, particularly surface-to-air missiles, plans for dedicated escort fighters designed to escort nuclear bombers gradually faded from the scene. Missile technology meant that interceptors would rarely engage bombers directly, if ever, as of bombers themselves, the advancement of land and submarine-based ballistic missiles relegated them to a lower importance—they became just a single element of the nuclear triad. In Vietnam for instance, F-4 Phantom IIs and sometimes F-8 Crusaders escorted the American bombers such as B-52 Stratofortresses, F-105 Thunderchiefs, in some cases the missions of F-4 were mixed, when some F-4 were equipped with bombs, and some F-4 acted as escorts. The development of the fighter, such as F/A-18, also decreased the need for escorts. Aerial warfare Interceptor, the adversary of an escort fighter Wild Weasel

Normandy landings
–
The Normandy landings were the landing operations on Tuesday,6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II. The largest seaborne invasion in history, the operation began the liberation of German-occupied northwestern Europe from Nazi control, planning for the operation began in 1943. Adolf Hitler placed German Field Marshal Erwin Rommel in command of German forces, the amphibious landings were preceded by extensive aerial and naval bombardment and an airborne assault—the landing of 24,000 American, British, and Canadian airborne troops shortly after midnight. Allied infantry and armoured divisions began landing on the coast of France at 06,30, the target 50-mile stretch of the Normandy coast was divided into five sectors, Utah, Omaha, Gold, Juno, and Sword. Strong winds blew the landing craft east of their positions, particularly at Utah. Casualties were heaviest at Omaha, with its high cliffs, at Gold, Juno, and Sword, several fortified towns were cleared in house-to-house fighting, and two major gun emplacements at Gold were disabled, using specialised tanks. The Allies failed to any of their goals on the first day. Carentan, St. Lô, and Bayeux remained in German hands, and Caen, German casualties on D-Day have been estimated at 4,000 to 9,000 men. Allied casualties were at least 10,000, with 4,414 confirmed dead, museums, memorials, and war cemeteries in the area now host many visitors each year. Between 27 May and 4 June 1940, over 338,000 troops of the British Expeditionary Force, after the German Army invaded the Soviet Union in June 1941, the Soviet leader Joseph Stalin began pressing his allies for the creation of a second front in western Europe. In late May 1942 the Soviet Union and the United States made a joint announcement that a. full understanding was reached with regard to the urgent tasks of creating a front in Europe in 1942. Instead of a return to France, the Western Allies staged offensives in the Mediterranean Theatre of Operations. By mid-1943 the campaign in North Africa had been won, the Allies then launched the invasion of Sicily in July 1943, and subsequently invaded Italy in September the same year. By then, Soviet forces were on the offensive and had won a victory at the Battle of Stalingrad. The decision to undertake a cross-channel invasion within the year was taken at the Trident Conference in Washington in May 1943. Initial planning was constrained by the number of landing craft, most of which were already committed in the Mediterranean. At the Tehran Conference in November 1943, Roosevelt and Churchill promised Stalin that they would open the second front in May 1944. Four sites were considered for the landings, Brittany, the Cotentin Peninsula, Normandy, as Brittany and Cotentin are peninsulas, it would have been possible for the Germans to cut off the Allied advance at a relatively narrow isthmus, so these sites were rejected

Air interdiction
–
It is a core capability of virtually all military air forces, and has been conducted in conflicts since World War I. A distinction is made between tactical and strategic air interdiction, depending on the objectives of the operation. Typical objectives in tactical interdiction are meant to affect events rapidly and locally, while strategic objectives are often broader and more long-term, with less direct attacks on enemy fighting capabilities, instead focusing on infrastructure, logistics and other supportive assets. The term deep air support, relates to air support. Close air support, as the name suggests, is directed towards targets close to ground units, as closely coordinated air-strikes. Deep air support or air interdiction is carried out further from the fighting, based more on strategic planning. Despite being more strategic than close air support, air interdiction should not be confused with strategic bombing, with air interdiction in World War I, the goal was to isolate the battlefield by strafing and bombing enemy supply lines. Favorite targets were railroad lines, bridges, and truck convoys, due to the primitive state of aircraft and weapons technology, as well as the undeveloped nature of air doctrine and tactics, air interdiction missions in World War I were of limited utility. The potential of air interdiction was clearly recognized, however, specifically, the Allies launched major air interdiction efforts in the North African, Italian, and Normandy campaigns. As a consequence of differences, the results of air interdiction also varied. The greatest success was in the terrain of North Africa. The Italian campaign, by contrast, was characterized by terrain, poor weather conditions. The diverse results of two campaigns taught air planners differing lessons. Air interdiction has continued to play a role in conflicts since World War II. Once again, differing local conditions and political restraints have had an effect on how air interdiction was conducted. In Vietnam, for example, the interdiction campaign known as Rolling Thunder was largely unsuccessful. The dense jungle terrain, poor intelligence on enemy movements, the flow of supplies and reinforcements from North Vietnam to their units in South Vietnam was not seriously affected. In contrast, coalition air interdiction efforts in the 1991 Gulf War were extremely successful in isolating front-line Iraqi units from their bases in the rear

Marshalling yard
–
A classification yard or marshalling yard is a railway yard found at some freight train stations, used to separate railway cars on to one of several tracks. First the cars are taken to a track, sometimes called a lead or a drill, from there the cars are sent through a series of switches called a ladder onto the classification tracks. Larger yards tend to put the lead on an artificially built hill called a hump to use the force of gravity to propel the cars through the ladder, freight trains that consist of isolated cars must be made into trains and divided according to their destinations. Thus the cars must be shunted several times along their route in contrast to a unit train and this shunting is done partly at the starting and final destinations and partly in classification yards. Flat yards are constructed on ground, or on a gentle slope. Freight cars are pushed by a locomotive and coast to their required location, hump yards are the largest and most effective classification yards, with the largest shunting capacity, often several thousand cars a day. The heart of these yards is the lead track on a small hill over which an engine pushes the cars. As concerns speed regulation, there are two types of hump yards—without or with mechanisation by retarders, in the old non-retarder yards braking was usually done in Europe by railroaders who laid skates onto the tracks. The skate or chock was manually placed on one or both of the rails so that the treadles or rims of the wheel or wheels caused frictional retardation, in the United States this braking was done by riders on the cars. In the modern retarder yards this work is done by mechanized rail brakes called retarders and they are operated either pneumatically or hydraulically. Pneumatic systems are prevalent in the United States, France, Belgium, Russia and China, while hydraulic systems are used in Germany, Italy and the Netherlands. In the United States, many classification bowls have more than 40 tracks—up to 72—which are often divided into six to ten tracks in each balloon loop. Bailey Yard in North Platte, Nebraska, United States, the worlds largest classification yard, is a hump yard, notably, in Europe, Russia and China, all major classification yards are hump yards. Europes largest hump yard is that of Maschen near Hamburg, Germany, the second largest is in the port of Antwerp, Belgium. According to the PRRT&HS PRR Chronology, the first hump yard in the United States was opened May 11,1903 as part of the Altoona Yards at Bells Mills. Other sources report the PRR yard at Youngwood, PA which opened in the 1880s to serve the Connellsville coke fields as the first U. S. hump yard. Gravity yards are operated similarly to hump yards but, in contrast to the latter, thus, only few gravity yards were ever built, sometimes requiring massive earthwork. Most gravity yards were built in Germany and Great Britain, a few also in some other European countries, in the USA, there were only very few old gravity yards, one of the few gravity yards in operation today is CSXs Readville Yard south of Boston, Massachusetts

Factory
–
Factories arose with the introduction of machinery during the Industrial Revolution when the capital and space requirements became too great for cottage industry or workshops. Early factories that contained small amounts of machinery, such as one or two spinning mules, and fewer than a dozen workers have been called glorified workshops, most modern factories have large warehouses or warehouse-like facilities that contain heavy equipment used for assembly line production. Large factories tend to be located with access to multiple modes of transportation, with some having rail, highway, factories may either make discrete products or some type of material continuously produced such as chemicals, pulp and paper, or refined oil products. Oil refineries have most of their equipment outdoors, discrete products may be final consumer goods, or parts and sub-assemblies which are made into final products elsewhere. Factories may be supplied parts from elsewhere or make them from raw materials, continuous production industries typically use heat or electricity to transform streams of raw materials into finished products. The term mill originally referred to the milling of grain, which usually used natural resources such as water or wind power until those were displaced by steam power in the 19th century. Because many processes like spinning and weaving, iron rolling, and paper manufacturing were originally powered by water, according to translations of Demosthenes and Herodotus, Naucratis was a, or the only, factory in the entirety of ancient Egypt. A source of 1983, states the largest factory production in ancient times was of 120 slaves within 4th century BC Athens, although The Cambridge Online Dictionary definition of factory states, a building or set of buildings where large amounts of goods are made using machines elsewhere. The wheel was invented circa 3000 BC, the spoked wheel c.2000 BC, the Iron Age began approximately 1200-1000 BC. However, other sources define machinery as a means of production, according to one text the water-mill was first made in 555 A. D. by Belisarius, although according to another they were known to Pliny the Elder and Vitruvius in the first century B. C. By the time of the 4th century A. D. mills with a capacity to grind 3 tonnes of cereal an hour, the Venice Arsenal provides one of the first examples of a factory in the modern sense of the word. Founded in 1104 in Venice, Republic of Venice, several hundred years before the Industrial Revolution, the Venice Arsenal apparently produced nearly one ship every day and, at its height, employed 16,000 people. One of the earliest factories was John Lombes water-powered silk mill at Derby, by 1746, an integrated brass mill was working at Warmley near Bristol. Raw material went in at one end, was smelted into brass and was turned into pans, pins, wire, housing was provided for workers on site. Josiah Wedgwood in Staffordshire and Matthew Boulton at his Soho Manufactory were other prominent early industrialists, the factory system began widespread use somewhat later when cotton spinning was mechanized. Richard Arkwright is the credited with inventing the prototype of the modern factory. After he patented his water frame in 1769, he established Cromford Mill, in Derbyshire, England, the factory system was a new way of organizing labour made necessary by the development of machines which were too large to house in a workers cottage. Working hours were as long as they had been for the farmer, overall, this practice essentially reduced skilled and unskilled workers to replaceable commodities

Close air support
–
The requirement for detailed integration because of proximity, fires or movement is the determining factor. CAS may need to be conducted during shaping operations with Special Operations Forces, if the mission requires detailed integration with the fire, the term battlefield air interdiction is not currently used in U. S. joint doctrine. Close air support requires excellent coordination with ground forces, in advanced modern militaries, this coordination is typically handled by specialists such as Joint Fires Observers s, Joint Terminal Attack Controllers s, and Forward Air Controllers s. The use of aircraft in the air support of ground forces dates back to World War I. By that point, the startling and demoralizing effect that attack from the air could have on the troops in the trenches had been made clear, at the Battle of the Somme,18 British armed reconnaissance planes strafed the enemy trenches after conducting surveillance operations. The success of this improvised assault spurred innovation on both sides, in 1917, following the Second Battle of the Aisne the British debuted the first ground-attack aircraft, a modified F. E 2b fighter carrying 20-lb bombs and mounted machine-guns. After exhausting their ammunition the planes returned to base for refuelling and rearming, other modified planes used in this role were the Airco DH.5 and Sopwith Camel—the latter was particularly successful in this role. Aircraft support was first integrated into a plan on a large scale at the 1917 Battle of Cambrai. British doctrine at the time came to two forms of air support, trench strafing, and ground strafing —attacking tactical ground targets away from the land battle. As well as strafing with machine-guns, the planes were modified with bomb racks, the Germans were also quick to adopt this new form of warfare and were able to deploy aircraft in a similar capacity at Cambrai. While the British used single-seater planes, the Germans preferred the use of heavier two-seaters with a machine gunner in the aft cockpit. The Germans adopted the powerful Hannover CL. II and built the first purpose built ground attack aircraft, during the 1918 Spring Offensive the Germans employed 30 squadrons, or Schlasta, of ground attack fighters and were able to achieve some initial tactical success. The British later deployed the Sopwith Salamander as a ground attack aircraft. It was during the Sinai and Palestine Campaign of 1918 that Close Air Support was first proven to be an important factor in ultimate victory, combined with a ground assault led by General Edmund Allenby, three Turkish armies soon collapsed into a full rout. In the words of the squadrons official report, No 1 Squadron made six heavy raids during the day. The panic and slaughter beggared description, the close air support doctrine was further developed in the interwar period. Most theorists advocated the adaptation of fighters or light bombers into the role, during this period, airpower advocates crystallized their views on the role of air-power in warfare. Aviators and ground officers developed largely opposing views on the importance of CAS, the inter-war period saw the use of CAS in a number of conflicts, including the Russo-Polish War, the Spanish Civil War, colonial wars in the Middle East and the Gran Chaco War

Battle of the Bulge
–
The Battle of the Bulge was the last major German offensive campaign of World War II. It was launched through the densely forested Ardennes region of Wallonia in Belgium, France, the surprise attack caught the Allied forces completely off guard. American forces bore the brunt of the attack and incurred their highest casualties of any operation during the war, the battle also severely depleted Germanys armoured forces on the Western Front, and they were largely unable to replace them. German personnel and later, Luftwaffe aircraft, also sustained heavy losses, the Germans officially referred to the offensive as Unternehmen Wacht am Rhein, while the Allies designated it the Ardennes Counteroffensive. The phrase Battle of the Bulge was coined by contemporary press to describe the bulge in German front lines on wartime news maps, once that was accomplished, the German dictator Adolf Hitler believed he could fully concentrate on the Soviets on the Eastern Front. The offensive was planned by the German forces with utmost secrecy, with minimal radio traffic and movements of troops, intercepted German communications indicating a substantial German offensive preparation were not acted upon by the Allies. The Germans achieved total surprise on the morning of 16 December 1944, due to a combination of Allied overconfidence, preoccupation with Allied offensive plans, and poor aerial reconnaissance. The Germans attacked a weakly defended section of the Allied line, columns of armor and infantry that were supposed to advance along parallel routes found themselves on the same roads. This, and terrain that favored the defenders, threw the German advance behind schedule, improved weather conditions permitted air attacks on German forces and supply lines, which sealed the failure of the offensive. In the wake of the defeat, many experienced German units were left severely depleted of men and equipment, the Germans initial attack involved 406,000 men,1,214 tanks, tank destroyers, and assault guns, and 4,224 artillery pieces. These were reinforced a couple of later, bringing the offensives total strength to around 450,000 troops. Between 67,200 and 125,000 of their men were killed, missing, for the Americans, out of 610,000 troops involved in the battle,89,000 were casualties. While some sources report that up to 19,000 were killed, British historian Antony Beevor reports the number killed as 8,407. It was the largest and bloodiest battle fought by the United States in World War II, after the breakout from Normandy at the end of July 1944 and the Allied landings in southern France on 15 August 1944, the Allies advanced toward Germany more quickly than anticipated. The Allies were faced with several military logistics issues, - troops were fatigued by weeks of continuous combat supply lines were stretched extremely thin supplies were dangerously depleted. General Dwight D. Eisenhower and his staff chose to hold the Ardennes region which was occupied by the U. S, the Allies chose to defend the Ardennes with as few troops as possible due to the favorable terrain and limited Allied operational objectives in the area. They also had intelligence that the Wehrmacht was using the area across the German border as an area for its troops. The speed of the Allied advance coupled with a lack of deep-water ports presented the Allies with enormous supply problems

Distinguished Unit Citation
–
The unit with the most Presidential Unit Citations is the USS Parche with 9 citations. The Army citation was established by Executive Order 9075 on 26 February 1942, superseded by Executive Order 9396 on Dec.2,1943, as with other Army unit citations, the PUC is in a larger frame than other ribbons, and is worn above the right pocket. All members of the unit may wear the decoration, whether or not they participated in the acts for which the unit was cited. Only those assigned to the unit at the time of the action cited may wear the decoration as a permanent award, for both the Army and Air Force, the emblem is a solid blue ribbon enclosed in a gold frame. The Air Force PUC was adopted from the Army Distinguished Unit Citation after the Air Force became a military branch in 1947. By Executive Order 10694, dated Jan,10,1957 the Air Force redesignated the Distinguished Unit Citation as the Presidential Unit Citation. The Air Force PUC is the color and design as the Army PUC but slightly smaller. The Citation is carried on the units colors in the form of a blue streamer,4 ft long and 2.75 in wide. For the Army, only on rare occasions will a larger than battalion qualify for award of this decoration. The Navy citation was established by Executive Order 9050 on 6 February 1942, the Navy version has blue, yellow, and red horizontal stripes, and is the only Navy ribbon having horizontal stripes. These are only worn by persons who meet the criteria at the time it is awarded to the unit, unlike the Army, those who later join the unit do not wear it on a temporary basis. The current decoration is known as the Department of Homeland Security Presidential Unit Citation. A Coast Guard version of the award was awarded to all U. S. Coast Guard and Coast Guard Auxiliary personnel responding to Hurricane Katrina by President George W. Bush for rescue, the United States Public Health Service Presidential Citation was established in 2015. The design was finalized by the Army Institute of Heraldry on 17 August 2015, two units of the Free French Forces were awarded Presidential Unit Citations during World War II. On April 22,1986, the 1st Fighter Group Força Aérea Brasileira was awarded the Presidential Unit Citation for its actions in the Po Valley region of Italy in World War II. The Brazilians, operating in Italy in support of Allied forces, destroyed in one day over 45 vehicles, strafed pontoon bridges on the River Po, eleven missions of 44 sorties were flown destroying nine motor transports and damaging 17. One Belgian-Luxembourgian battalion of the Belgian United Nations Command was awarded the Presidential Unit Citation once for actions during the Battle of the Imjin River, the Colombia Battalion received the citation while attached to the American 21st Infantry Regiment in 1951. One Dutch unit, the Netherlands Detachment United Nations, part of the Regiment Van Heutsz, was awarded the Presidential Unit Citation twice for actions during the Korean War, the first citation was awarded after the battle near Wonju and Hoengson in February 1951

Axis powers
–
The Axis powers, also known as the Rome–Berlin–Tokyo Axis, were the nations that fought in World War II against the Allied Powers. The Axis agreed on their opposition to the Allies, but did not completely coordinate their activity, the Axis grew out of the diplomatic efforts of Germany, Italy, and Japan to secure their own specific expansionist interests in the mid-1930s. The first step was the treaty signed by Germany and Italy in October 1936, Mussolini declared on 1 November that all other European countries would from then on rotate on the Rome–Berlin axis, thus creating the term Axis. The almost simultaneous second step was the signing in November 1936 of the Anti-Comintern Pact, Italy joined the Pact in 1937. At its zenith during World War II, the Axis presided over territories that occupied parts of Europe, North Africa. There were no three-way summit meetings and cooperation and coordination was minimal, the war ended in 1945 with the defeat of the Axis powers and the dissolution of their alliance. As in the case of the Allies, membership of the Axis was fluid, at the time he was seeking an alliance with the Weimar Republic against Yugoslavia and France in the dispute over the Free State of Fiume. The term was used by Hungarys prime minister Gyula Gömbös when advocating an alliance of Hungary with Germany, when Mussolini publicly announced the signing on 1 November, he proclaimed the creation of a Rome–Berlin axis. Italy under Duce Benito Mussolini had pursued an alliance of Italy with Germany against France since the early 1920s. He believed that Italy could expand its influence in Europe by allying with Germany against France, in early 1923, as a goodwill gesture to Germany, Italy secretly delivered weapons for the German Army, which had faced major disarmament under the provisions of the Treaty of Versailles. General Hans von Seeckt supported an alliance between Germany and the Soviet Union to invade and partition Poland between them and restore the German-Russian border of 1914. The discussions concluded that Germans still wanted a war of revenge against France but were short on weapons, however at this time Mussolini stressed one important condition that Italy must pursue in an alliance with Germany, that Italy must. Tow them, not be towed by them, the French government warned Italy that it had to choose whether to be on the side of the pro-Versailles powers or that of the anti-Versailles revanchists. Grandi responded that Italy would be willing to offer France support against Germany if France gave Italy its mandate over Cameroon, France refused Italys proposed exchange for support, as it believed Italys demands were unacceptable and the threat from Germany was not yet immediate. In 1932, Gyula Gömbös and the Party of National Unity rose to power in Hungary, Gömbös sought to alter Hungarys post–Treaty of Trianon borders by forming an alliance with Austria and Italy, knowing that Hungary alone was not capable of challenging the Little Entente powers. At the meeting between Gömbös and Mussolini in Rome on 10 November 1932, the question came up of the sovereignty of Austria in relation to the rise to power in Germany of the Nazi Party. Mussolini was worried about Nazi ambitions towards Austria, and indicated that at least in the term he was committed to maintaining Austria as a sovereign state. Italy had concerns over a Germany which included Austria laying land claims to German-populated territories of the South Tyrol within Italy, Mussolini said he hoped the Anschluss could be postponed as long as possible until the breakout of a European war that he estimated would begin in 1938

German Instrument of Surrender
–
The German Instrument of Surrender ended World War II in Europe. An earlier version of the text had been signed in a ceremony in Reims in the hours of 7 May 1945. In the West,8 May is known as Victory in Europe Day, whereas in post-Soviet states the Victory Day is celebrated on 9 May, there were three language versions of the surrender document. The Russian and English versions were the only authoritative ones, by 3 January 1944, the Working Security Committee in the EAC proposed that the capitulation of Germany should be recorded in a single document of unconditional surrender. The committee further suggested that the instrument of surrender be signed by representatives of the German High Command, not everyone agreed with the Working Security Committees predictions regarding the wars ending. Ambassador William Strang, British representative at the EAC, claimed as follows, the surrender terms for Germany were first discussed at the first EAC meeting on 14 January 1944. A definitive text was agreed on 28 July 1944, and was adopted by the three Allied Powers. The agreed text was in three parts, the instrument of surrender itself followed in fourteen articles. Articles 13 and 14 specified the date of surrender and the languages of the definitive texts, while this was unresolved, there were in effect two versions of the EAC text, with and without the dismemberment clause. These guidelines formed the basis for the series of capitulations of German forces to the Western Allies in April. But that did mean that the text as signed at Reims had not been agreed in advance with the Soviet High Command. But with the fall of Berlin two days later, and American and Soviet forces having linked up at Torgau on the Elbe, the area of Germany still under German military control had been split in two. German military commanders in Italy had been conducting secret negotiations for a partial surrender, field Marshal Albert Kesselring, with overall military command for OKW-South, initially denounced the capitulation, but once Hitlers death had been confirmed, acceded to it. On 5 May 1945, all German forces in Bavaria and Southwest Germany signed an act of surrender to the Americans at Haar, outside Munich, in addition, Dönitz hoped to continue to evacuate soldiers and civilians by sea from the Hela peninsula and the surrounding Baltic coastal areas. From 5 May, Army Group Centre was also engaged in the suppression of the Prague uprising. The surrenders in the west had succeeded in ceasing hostilities between the Western allies and German forces on almost all fronts, German forces in the east were ordered instead to fight their way westwards. Dönitzs representative, Admiral Friedeburg, informed him on 6 May that Eisenhower was now insisting on immediate, simultaneous, the signing took place in a red brick schoolhouse, the Collège Moderne et Technique de Reims, that served as the Supreme Headquarters Allied Expeditionary Force. It was to take effect at 23,01 CET on 8 May, the unconditional surrender of the German armed forces was signed by Jodl, on behalf of the Oberkommando der Wehrmacht

Military occupation
–
Military occupation is effective provisional control by a certain ruling power over a territory which is not under the formal sovereignty of that entity, without the volition of the actual sovereign. Military government may be characterized as the administration or supervision of occupied territory. Military government is distinguished from law, which is the temporary rule by domestic armed forces over disturbed areas. The rules of government are delineated in various international agreements, primarily the Hague Convention of 1907. A country that establishes a government and violates internationally agreed upon norms runs the risk of censure, criticism. In the current era, the practices of government have largely become a part of customary international law. Article 42 of the 1907 Hague Convention on Land Warfare specify that erritory is considered occupied when it is placed under the authority of the hostile army. The form of administration by which an occupying power exercises government authority over occupied territory is called military government, neither the Hague Conventions nor the Geneva Conventions specifically define or distinguish an act of invasion. The terminology of occupation is used exclusively, the clear distinction has been recognized among the principles of international law since the end of the Napoleonic wars in the 19th century. These customary laws of belligerent occupation which evolved as part of the laws of war gave some protection to the population under the occupation of a belligerent power. The first two articles of that state, Art. Territory is considered occupied when it is placed under the authority of the hostile army. The occupation extends only to the territory where such authority has been established, in 1949 these laws governing belligerent occupation of an enemy states territory were further extended by the adoption of the Fourth Geneva Convention. Much of GCIV is relevant to protected persons in occupied territories and Section III, Article 6 restricts the length of time that most of GCIV applies, The present Convention shall apply from the outset of any conflict or occupation mentioned in Article 2. In the territory of Parties to the conflict, the application of the present Convention shall cease on the close of military operations. GCIV emphasised an important change in international law, the Occupying Power shall not deport or transfer parts of its own civilian population into the territory it occupies. S. are not signatory to this additional protocol. The military government of the occupying power will continue past the point in time when the peace treaty comes into force. Military government continues until legally supplanted is the rule, as stated in Military Government and Martial Law, by William E. Birkhimer, see Birkhimer, p. 25–26, No proclamation of part of the victorious commander is necessary to the lawful inauguration and enforcement of military government

Boeing B-17 Flying Fortress
–
The Boeing B-17 Flying Fortress is a four-engine heavy bomber developed in the 1930s for the United States Army Air Corps. Competing against Douglas and Martin for a contract to build 200 bombers, although Boeing lost the contract because the prototype crashed, the air corps ordered 13 more B-17s for further evaluation. From its introduction in 1938, the B-17 Flying Fortress evolved through numerous design advances, the B-17 was primarily employed by the United States Army Air Forces in the daylight strategic bombing campaign of World War II against German industrial and military targets. The B-17 also participated to an extent in the War in the Pacific, early in World War II. From its prewar inception, the USAAC promoted the aircraft as a weapon, it was a relatively fast, high-flying. It developed a reputation for toughness based upon stories and photos of badly damaged B-17s safely returning to base, the B-17 developed a reputation as an effective bomber, dropping more bombs than any other U. S. aircraft in World War II. Of the 1.5 million tonnes of bombs dropped on Germany, in addition to its role as a bomber, the B-17 was also employed as a transport, antisubmarine aircraft, drone controller, and search-and-rescue aircraft. As of May 2015, ten aircraft remain airworthy, none of them are combat veterans. Dozens more are in storage or on static display, the oldest of these is a D-series veteran of combat in the Pacific and the Caribbean. On 8 August 1934, the U. S. Army Air Corps tendered a proposal for a bomber to replace the Martin B-10. The air corps was looking for a capable of reinforcing the air forces in Hawaii, Panama. Requirements were that it would carry a useful bombload at an altitude of 10,000 ft for ten hours with a top speed of at least 200 mph. They also desired, but did not require, a range of 2,000 mi, the competition for the air corps contract would be decided by a fly-off between Boeings design, the Douglas DB-1, and the Martin Model 146 at Wright Field in Dayton, Ohio. The prototype B-17, with the Boeing factory designation of Model 299, was designed by a team of engineers led by E. Gifford Emery and Edward Curtis Wells and it combined features of the experimental Boeing XB-15 bomber with the Boeing 247 transport aircraft. The B-17s armament consisted of up to 4,800 lb of bombs on two racks in the bay behind the cockpit, and initially possessed five.30 caliber machine guns. It was powered by four Pratt & Whitney R-1690 Hornet radial engines each producing 750 hp at 7,000 ft, the first flight of the Model 299 was on 28 July 1935 with Boeing chief test-pilot Leslie Tower at the controls. Richard Williams, a reporter for the Seattle Times, coined the name Flying Fortress with his comment, Why, when the Model 299 was rolled out bristling with multiple machine gun installations. The most unusual gun emplacement was the installation which allowed the single machine gun to be fired toward almost any frontal angle

North American P-51 Mustang
–
The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II, the Korean War and other conflicts. The Mustang was designed in 1940 by North American Aviation in response to a requirement of the British Purchasing Commission, the Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force. Rather than build an old design from another company, North American Aviation proposed the design, the prototype NA-73X airframe was rolled out on 9 September 1940,102 days after the contract was signed, and first flew on 26 October. The Mustang was originally designed to use the Allison V-1710 engine and it was first flown operationally by the RAF as a tactical-reconnaissance aircraft and fighter-bomber. The addition of the Rolls-Royce Merlin to the P-51B/C model transformed the Mustangs performance at altitudes above 15,000 ft, the P-51 was also used by Allied air forces in the North African, Mediterranean, Italian and Pacific theaters. During World War II, Mustang pilots claimed to have destroyed 4,950 enemy aircraft, despite the advent of jet fighters, the Mustang remained in service with some air forces until the early 1980s. After the Korean War, Mustangs became popular civilian warbird and air racing aircraft, in April 1940 the British government established a purchasing commission in the United States, headed by Sir Henry Self. Self was given responsibility for Royal Air Force production and research and development, and also served with Sir Wilfrid Freeman. Self also sat on the British Air Council Sub-committee on Supply and one of his tasks was to organize the manufacturing and supply of American fighter aircraft for the RAF. At the time, the choice was limited, as no U. S. aircraft then in production or flying met European standards. The Curtiss-Wright plant was running at capacity, so P-40s were in short supply, North American Aviation was already supplying its Harvard trainer to the RAF, but was otherwise underutilized. NAA President Dutch Kindelberger approached Self to sell a new medium bomber, instead, Self asked if NAA could manufacture the Tomahawk under license from Curtiss. Kindelberger said NAA could have an aircraft with the same engine in the air sooner than establishing a production line for the P-40. In March 1940,320 aircraft were ordered by Sir Wilfred Freeman who had become the head of the Ministry of Aircraft Production. The NA-73X, which was designed by a led by lead engineer Edgar Schmued, followed the best conventional practice of the era. One was a wing designed using laminar flow airfoils which were developed co-operatively by North American Aviation and these airfoils generated very low drag at high speeds. The results of this test showed the superiority of the wing designed with the NAA/NACA 45–100 airfoils, the other feature was a new cooling arrangement that reduced the cooling drag. It was later discovered that, after lot of development, the assembly could take advantage of the Meredith Effect

Fourth Air Force
–
The Fourth Air Force is a numbered air force of the United States Air Force Reserve. It is headquartered at March Air Reserve Base, California,4 AF directs the activities and supervises the training of more than 30,000 Air Force Reservists. If called to duty,4 AFs ready reserve units would be assigned to Air Mobility Command. During the war, its mission became the organization and training of combat units prior to their deployment to the overseas combat air forces. 4 AF is commanded by Major General John C, Fourth Air Force is dedicated to ensuring its units and personnel are fully prepared to accomplish all assigned missions in support of national objectives. The sixty person staff consists of Traditional Reservists, Air Reserve Technicians and they direct the activities and supervise the equipping and training of more than 30,000 Air Force reservists in unit programs located across the continental United States, Alaska, Hawaii and Guam. Reservists from 4 AF units are deployed to Air Expeditionary units in combat areas of Central. It was redesignated Fourth Air Force on 26 March 1941 with a mission for the defense of the Southwest, during World War II Fourth Air Force was the primary air defense command for the West Coast. The command also flew antisubmarine patrols along coastal areas of the Gulf of Mexico from after Pearl Harbor until October 1942, one of its primary fighter units was the 10th Fighter Wing at Hamilton Field, California. On 29 September 1942, Rice Municipal Airport located in the Desert Training Center was acquired by the IV Air Support Command, re-designated Rice AAF it was used to train pilots and crews of aircraft whose mission it was to support ground troops. The Fourth Air Force became predominantly a fighter OTU and RTU organization, most P-51 Mustang and P-38 Lightning groups were trained by Fourth Air Force primarily due to the proximity of their manufacturing plants in Southern California. Air Defense Wings were also organized for the metropolitan areas along the West Coast. By 1944 the likelihood of an air attack along the West Coast was remote, on 13 December 1944, First, Second, Third and Fourth Air Force were all were placed under the unified command of the Continental Air Forces. It was also responsible for training Air Force Reserve and Air National Guard personnel throughout the region, on 1 September 1960, Air Defense Command inactivated Fourth Air Force, transferring its reserve training mission to the Sixth Air Force Reserve Region. Fourth Air Force was re-activated on 20 January 1966 again at Hamilton AFB and its area of responsibility was essentially unchanged from its 1948 region. Subordinate organizations assigned by ADC were the 25th 26th and 27th Air Divisions, on 16 January 1968 Air Defense Command was re-designated Aerospace Defense Command as part of a restructuring of USAF air defense forces. ADCOM reassigned the units under the inactivated Fourth Air Force were reassigned primarily to the 25th and 26th Air Divisions. The command remained inactive until 8 October 1976, when it was activated as Fourth Air Force at McClellan Air Force Base, CA, Fourth Air Force has been a key component of the Air Force reserve ever since

Continental Air Command
–
Continental Air Command was a Major Command of the United States Air Force responsible primarily for administering the Air National Guard and Air Force Reserve. During the Korean War, ConAC provided the necessary augmentation to the regular Air Force while it rebuilt itself under wartime conditions, later, during the 1950s, it was a training force for reservists with no prior military service. ConAC provided peacetime airlift missions for the Air Force and it was mobilized twice in 1961 and 1962 by president Kennedy for the Berlin and Cuban Missile Crisis. Lastly, it was used by president Lyndon B. Johnson for airlift operations into the Dominican Republic and it was inactivated in 1968 and replaced by Headquarters, Air Force Reserve. After the end of World War II, the Truman Administration was determined to bring the Federal budget back into balance, an enormous deficit had built up, so expenditure was cut, resulting in relatively little money for the new United States Air Force to modernize its forces. Planning for reserve forces took place, in any event. Their single firm conviction about the nature of the program was that it must provide opportunities for pilots to fly. This was fundamentally different from the National Guard concept, the National Guard is the designated state militia by the Constitution of the United States. Although the Air National Guard fulfills state and some federal needs, in the first place, not every person in the United States with an obligation or desire for military service wants to serve in a state militia. Second, the prescribed nature and organization of the National Guard does not provide for service as individuals. As the Army Air Forces demobilized in 1945 and 1946, inactivated unit designations were allotted and transferred to various State Air National Guard bureaus, as individual units were organized, they began obtaining federal recognition, and the state Air National Guard units were established. The Army Air Forces Air Reserve program was approved by the War Department in July 1946, Army Air Forces Base Units were organized by Air Defense Command at each training location. They were located at both Army Airfields and civil airports where the Air Force retained partial jurisdiction after turning over the facility to the community after the end of World War II. The reservists were to report to a unit located in their area. The base unit furnished the personnel to operate the detachment and provided base services. ADC programmed to have AT-6 Texans, AT-11 Kansans and P-51 Mustangs available for pilots to fly four hours per month to train and maintain proficiency. ADC intended to activate forty base units operational by 1 July, by the end of 1946, the command had organized Air Reserve training detachments at seventy bases and airfields. On 21 February 1947, Headquarters Army Air Forces informed ADC to eliminate twenty-nine reserve training detachments as quickly as possible, the Air Force Reserve was affected by fundamental legislation pertaining to the parent Air Force

National Guard Bureau
–
It was created by the Militia Act of 1903. The National Defense Authorization Act for Fiscal Year 2008, elevated the National Guard to a joint function of the Department of Defense. This act also elevated the Chief of the National Guard Bureau from Lieutenant General to General with the appointment of General Craig R. McKinley, the National Guard Bureau holds a unique status as both a staff and operation agency. United States Secretary of War Elihu Root militated for reform of the guard, in annual reports of 1901 of 1903. The Militia Act of 1792 was obsolete, the resulting Militia Act of 1903 became law. It gave federal status to the militia and required the militia of the States to conform to Regular Army organization. It dramatically increased funding of the militia, between 1903 and 1916, the federal government spent $53 million on the Guard, more than the total of the previous hundred years. The 1903 act authorized the creation of a section responsible for National Guard affairs. The Division remained a part of the Office of the Secretary of War until July 25,1910 when the Chief was directed to report directly to the Army Chief of Staff. The Division continued to perform under the jurisdiction of the Chief of Staff until the passage of the National Defense Act of June 3,1916. Then the Division of Militia Affairs became the Militia Bureau of the War Department, the National Defense Act of 1916 is the most important piece of legislation in the history of the National Guard. It transformed the militia from individual state forces into a Reserve Component of the U. S. Army—and made the term National Guard mandatory. The act stated that all units would have to be recognized. It increased the number of training days to 15, increased the number of yearly drills to 48. The 1916 act transformed the Division of Militia Affairs into a separate Militia Bureau, increasing its autonomy, eight new civilian positions were authorized, something which the various Chiefs had been requesting for years, the number of military assigned to the Bureau had grown to 13. The National Defense Act also authorized the President to assign two National Guard officers to duty with the Militia Bureau, the inclusion of National Guard officers in the Militia Bureau was an important step towards creating a centralized planning organization for the National Guard headed by its own officers. The first National Guard officer assigned to the Bureau was Major Louis C. Wilson of Texas in 1916, thus the National Guard Bureau was charged with the responsibility of maintaining high standards in the National Guard. Prior to 1910 the Chief of the Militia Bureau was a Regular Army officer and this situation changed on June 4,1920, when Congress passed an amendment to the National Defense Act of 1916

Korean War
–
The Korean War began when North Korea invaded South Korea. The United Nations, with the United States as the principal force, China came to the aid of North Korea, and the Soviet Union gave some assistance. Korea was ruled by Japan from 1910 until the days of World War II. In August 1945, the Soviet Union declared war on Japan, as a result of an agreement with the United States, U. S. forces subsequently moved into the south. By 1948, as a product of the Cold War between the Soviet Union and the United States, Korea was split into two regions, with separate governments, both governments claimed to be the legitimate government of all of Korea, and neither side accepted the border as permanent. The conflict escalated into open warfare when North Korean forces—supported by the Soviet Union, on that day, the United Nations Security Council recognized this North Korean act as invasion and called for an immediate ceasefire. On 27 June, the Security Council adopted S/RES/83, Complaint of aggression upon the Republic of Korea and decided the formation, twenty-one countries of the United Nations eventually contributed to the UN force, with the United States providing 88% of the UNs military personnel. After the first two months of war, South Korean forces were on the point of defeat, forced back to the Pusan Perimeter, in September 1950, an amphibious UN counter-offensive was launched at Inchon, and cut off many North Korean troops. Those who escaped envelopment and capture were rapidly forced back north all the way to the border with China at the Yalu River, at this point, in October 1950, Chinese forces crossed the Yalu and entered the war. Chinese intervention triggered a retreat of UN forces which continued until mid-1951, after these reversals of fortune, which saw Seoul change hands four times, the last two years of fighting became a war of attrition, with the front line close to the 38th parallel. The war in the air, however, was never a stalemate, North Korea was subject to a massive bombing campaign. Jet fighters confronted each other in combat for the first time in history. The fighting ended on 27 July 1953, when an armistice was signed, the agreement created the Korean Demilitarized Zone to separate North and South Korea, and allowed the return of prisoners. However, no treaty has been signed, and the two Koreas are technically still at war. Periodic clashes, many of which are deadly, continue to the present, in the U. S. the war was initially described by President Harry S. Truman as a police action as it was an undeclared military action, conducted under the auspices of the United Nations. In South Korea, the war is referred to as 625 or the 6–2–5 Upheaval. In North Korea, the war is referred to as the Fatherland Liberation War or alternatively the Chosǒn War. In China, the war is called the War to Resist U. S

Aerospace Defense Command
–
Aerospace Defense Command was a major command of the United States Air Forces, responsible for continental air defence. It was activated in 1968 and disbanded in 1980 and its predecessor, Air Defense Command, was established in 1946, briefly inactivated in 1950, reactivated in 1951, and then redesignated Aerospace rather than Air in 1968. Its mission was to air defense of the Continental United States. It directly controlled all active measures, and was tasked to coordinate all passive means of air defense, the air districts established on 16 January 1941 before the Pearl Harbor attack. The four air districts also handled USAAF combat training with the Army Ground Forces and organization and training of bomber, fighter and other units, the USAAFs Aircraft Warning Corps provided air defense warning with information centers that networked an areas Army Radar Stations which communicated radar tracks by telephone. The AWC information centers also integrated visual reports processed by Ground Observer Corps filter centers, AWC information centers notified air defense command posts of the 4 continental air forces for deploying interceptor aircraft which used command guidance for ground-controlled interception. The USAAF inactivated the aircraft warning network in April 1944, Continental Air Forces was activated on 12 December 1944 with the four Air Forces as components to consolidate the CONUS air defense mission under one command. The Continental Air Forces reorganization began in 1945, when ground radar, the Distant Early Warning Line was first conceived—and rejected—in 1946. By 1948 there were only 5 AC&W stations, including the Twin Lights station in NJ that opened in June and Montauk NY Air Warning Station #3 --cf. SAC radar stations, e. g. at Dallas & Denver Bomb Plots. By the time ADC was inactivated on 1 July 1950, ADC had deployed the Lashup Radar Network with existing radars at 43 sites, in addition,36 Air National Guard fighter units were called to active duty for the mission. ADC was reinstated as a command on 1 January 1951 at Mitchel Air Force Base. The headquarters was moved to Ent Air Force Base in Colorado Springs on 8 January 1951 and it received 21 former ConAC active-duty fighter squadrons. ADC was also assigned the 25th, 26th 27th and 28th Air Divisions ADC completed the Priority Permanent System network for Aircraft Warning, gaps were filled by additional Federal Aviation Administration radar stations and the Ground Observation Corps. During the mid-1950s, planners devised the idea of extending the wall of powerful land-based radar seaward with Airborne early warning, the RC-121s, EC-121s and Texas Towers, it was believed, would contribute to extending contiguous east-coast radar coverage some 300 to 500 miles seaward. In terms of the air threat of the 1950s, this meant a gain of at least 30 extra minutes warning time of a bomber attack. ADCs Operation Tail Wind on 11–12 July tested its augmentation plan that required Air Training Command interceptors participate in an air defense emergency, a total of seven ATC bases actively participated in the exercise, deploying aircraft and aircrews and supporting the ADC radar net. As the USAF prepared to deploy the Tactical Air Command E-3 Sentry in the later 1970s, all remaining EC-121s were transferred to the Air Force Reserve, which formed the 79th AEWCS at Homestead Air Force Base, Florida in early 1976. Besides monitoring Cuban waters, these last Warning Stars also operated from NAS Keflavik, final EC-121 operations ended in September 1978

North American F-86 Sabre
–
The North American F-86 Sabre, sometimes called the Sabrejet, is a transonic jet fighter aircraft. Considered one of the best and most important fighter aircraft in that war and its success led to an extended production run of more than 7,800 aircraft between 1949 and 1956, in the United States, Japan and Italy. Variants were built in Canada and Australia, the Canadair Sabre added another 1,815 airframes, and the significantly redesigned CAC Sabre, had a production run of 112. The Sabre was by far the most-produced Western jet fighter, with production of all variants at 9,860 units. North American Aviation had produced the propeller-powered P-51 Mustang in World War II, by late 1944, North American proposed its first jet fighter to the U. S. Navy, which became the FJ-1 Fury. It was an unexceptional transitional jet fighter that had a wing derived from the P-51. Initial proposals to meet a United States Army Air Forces requirement for a medium-range, single-seat, in early 1945, North American Aviation submitted four designs. The USAAF selected one design over the others, and granted North American a contract to build three examples of the XP-86, despite the gain in speed, early studies revealed the XP-86 would have the same performance as its rivals, the XP-80 and XP-84. It was also feared that, because these designs were advanced in their development stages. Crucially, the XP-86 would not be able to meet the top speed of 600 mph. The North American F-86 Sabre was the first American aircraft to take advantage of research data seized from the German aerodynamicists at the end of World War II. By 1944, German engineers and designers had established the benefits of swept wings based on designs dating back to 1940. Study of the data showed that a wing would solve their speed problem. Because development of the XP-86 had reached a stage, the idea of changing the sweep of the wing was met with resistance from some senior North American staff. Despite stiff opposition, after results were obtained in wind tunnel tests. Many Sabres had the 6–3 wing retrofitted after combat experience was gained in Korea and this modification changed the wing airfoils to the NACA 0009-64 mod at the root and the NACA0008. 1–64 mod at the tip. Delays caused by the major redesign meant that manufacturing did not begin until after World War II, the XP-86 prototype, which would lead to the F-86 Sabre, was rolled out on 8 August 1947. The maiden flight occurred on 1 October 1947 with George Welch at the controls, flying from Muroc Dry Lake, the United States Air Forces Strategic Air Command had F-86 Sabres in service from 1949 through 1950

124th Fighter Group
–
The 124th Fighter Wing is a unit of the Idaho Air National Guard, stationed at Gowen Field Air National Guard Base, Boise, Idaho. If activated to service, the Wing is gained by the United States Air Force Air Combat Command. S. The 190th FIS becoming the flying squadron. Other squadrons assigned into the group were the 124th Headquarters, 124th Material Squadron, 124th Combat Support Squadron, also in 1955, the F-86A day interceptors were replaced by the F-94A Starfire all-weather interceptor. The 190th changed aircraft four times over the next 23 years to fly the F-89C Scorpion, F-86L Sabre Interceptor. In 1958, the 124th implemented the ADC Runway Alert Program, in which interceptors of the 190th FIS were committed to a runway alert. In 1968 Air Defense Command was re-designated as Aerospace Defense Command, in November 1975, the 124th Fighter-Interceptor Group was transferred from Air Defense Command to Tactical Air Command. It was re-equipped by TAC with the RF-4C Phantom II Mach 2 high speed reconnaissance aircraft, many of these planes were veterans of combat in Vietnam. F-4 Phantom jets would eventually spend 20 years on Gowen Field, the unarmed RF-4C carried high resolution cameras and electronic sensors, which soon proved their worth to thousands of people in Idaho. Aerial photographs were taken immediately after the 1983 Borah Peak earthquake near Challis. The Challis-Mackay region experienced rather thorough damage, with 11 commercial buildings and 39 homes with major damage, while another 200 houses were damaged, the reconnaissance photos helped emergency response crews locate and evaluate the damage. The RF-4C was still in service at the time of the 1991 Gulf War, Operation Desert Storm, following the end of Desert Storm, all of the remaining RF-4Cs were withdrawn from USAF service. In 1991, Idaho’s Air Guard changed aircraft and mission again, the Idaho ANG was to be the only ANG unit to operate the F-4G. The F-4G was designed as an anti-Surface to Air Missile aircraft to jam, the F-4Gs were received from the 37th Tactical Fighter Wing at George AFB, California as part of the closure of George AFB. The squadron was re-designated as the 190th Fighter Squadron with the changeover of its parent 124th to the Air Force Objective Wing organization, in 1992, the 124th Fighter Group became part of the new Air Combat Command. In April 1993 the squadrons Wild Weasel jets were sent to Southwest Asia to support Operation Southern Watch, twice 190th airmen were challenged by illegal Iraqi air defense radar near Basra. The threats were answered — and silenced — with AGM-88 High-Speed Anti-Radiation Missile anti-radiation missiles, from 1993 to 1995 there were a total of four deployments to the Gulf. The last such deployment returned to Boise in December 1995, Idaho’s airmen served longer in Southwest Asia than any other flying unit in the Air National Guard

Lockheed F-94 Starfire
–
The Lockheed F-94 Starfire was a first-generation jet aircraft of the United States Air Force. It was developed from the twin-seat Lockheed T-33 Shooting Star in the late 1940s as an all-weather, the aircraft reached operational service in May 1950 with Air Defense Command, replacing the piston-engined North American F-82 Twin Mustang in the all-weather interceptor role. The F-94 was the first operational USAF fighter equipped with an afterburner and was the first jet-powered all-weather fighter to combat during the Korean War in January 1953. It had a brief operational life, being replaced in the mid-1950s by the Northrop F-89 Scorpion. The last aircraft left active-duty service in 1958 and Air National Guard service in 1959, the F-94 was derived from the TF-80C which was a two-seat trainer version of the F-80 Shooting Star. A lengthened nose area with guns, radar and automatic control system was added. Since the conversion seemed so simple, a contract was awarded to Lockheed in early 1949, the early test YF-94s used 75% of the parts used in the earlier F-80 and T-33As. The fire control system was the Hughes E-1, which incorporated an AN/APG-33 radar and this short-range radar system was useful only in the terminal phases of the interception. Most of the operation would be directed using ground-controlled interception, as was the case with the aircraft it replaced. The combination reduced the fuel capacity. The F-94 was to be the first US production jet with an afterburner, the J33-A-33 had standard thrust of 4,000 pounds-force, and with water injection this was increased to 5,400 pounds-force and with afterburning a maximum of 6,000 pounds-force thrust. The YF-94As afterburner had many teething problems with its igniter and the stabilization system. The initial production model was the F-94A, which entered service in May 1950. Its armament was four 0.50 in M3 Browning machine guns mounted in the fuselage with the muzzles exiting just behind the radome, two 165 US Gallon drop tanks, as carried by the F-80 and T-33, could be carried beneath the wingtips. Alternatively, these could be replaced by 1,000 lb bombs, the F-94A was in operational service for only a brief time as it was originally built, and was not received well by its aircrews. Primarily, this was due to the unreliability of its J33 engine, the aircraft was judged as unstable and hard to maneuver at high altitude by its pilots. The pilot and radar operator found that the cockpit was too narrow for them to be able to get in and out of the aircraft quickly during alerts, the clearance for the ejection seats was too small, resulting in several tragic accidents during emergency ejections. The subsequent F-94B, which entered service in January 1951, was virtually identical to the F-94A

Northrop F-89 Scorpion
–
The Northrop F-89 Scorpion was an American all-weather interceptor built during the 1950s, the first jet-powered aircraft designed as such from the outset to enter service. The Scorpion stemmed from a United States Army Air Forces Air Technical Service Command specification for a fighter to replace the P-61 Black Widow. The preliminary specification, sent to manufacturers on 28 August 1945. The aircraft was to be armed with aerial rockets stored internally, each mount had to be capable of 15° of movement from the longitudinal axis of the aircraft. Each mounts guns were to be controlled by radar. For ground attack, it had to be capable of carrying 1, 000-pound bombs, bell Aircraft, Consolidated-Vultee, Douglas Aircraft, Goodyear, Northrop and Curtiss-Wright all submitted proposals. In March 1946, the USAAF selected the Curtiss-Wright XP-87, adapted from their proposed XA-43 attack aircraft, the N-24, designed by Jack Northrop, was a slim-bodied swept-wing aircraft with a two-man pressurized cockpit and conventional landing gear. To reduce drag, the two Allison J35 turbojet engines were buried in the fuselage, directly behind their air intakes. The horizontal stabilizer was mounted just above the junction of the stabilizer with the fuselage and had some dihedral. It was inspected on 25 September, and the USAAF was not impressed, other changes had to be made as wind tunnel and other aerodynamic tests were conducted. The swept wings proved to be less satisfactory at low speeds, delivery of the first prototype was scheduled for November 1947,14 months after the inspection. The position of the horizontal stabilizer proved to be unsatisfactory, as it was affected by the engine exhaust, moving the horizontal stabilizer forward solved the problem. Another major change occurred when USAAF revised its specification to delete the rear gun installation on 8 October, another inspection of the mock-up was held on 17 December, and the inspectors only suggested minor changes, even though the fuselage fuel tanks were still above the engines. Northrops efforts to protect the tanks were considered sufficient, as the only alternative was to redesign the entire aircraft. The XP-89 had a thin, straight, mid-mounted wing and a crew of two, seated in tandem, the slim rear fuselage and the high-mounted horizontal stabilizer led Northrop employees calling it the Scorpion—a name later formally adopted by the Air Force. The intended armament of four 20 mm M-24 cannon in a nose turret was not ready when the XP-89 was completed in 1948. Pending the availability of either of the two turrets under development, an interim six-gun fixed installation, with 200 rounds per gun, was designed for the underside of the nose. The thin wing had a ratio of 9% and used a NACA 0009-64 section

F-86L Sabre Interceptor
–
The North American F-86D Sabre was a transonic jet all-weather interceptor of the United States Air Force and others. Based on North Americans F-86 Sabre day fighter, the F-86D had only 25 percent commonality with other Sabre variants, with a fuselage, larger afterburner engine. The YF-95 was a development of the F-86 Sabre, the first aircraft designed around the new 2. 75-inch Mighty Mouse Folding-Fin Aerial Rocket, a second prototype, 50-578, was also built, but the YF-95 nomenclature was short-lived as the design was subsequently redesignated YF-86D. Later models of the F-86D received an uprated J-47-GE-33 engine rated at 5,550 lbf, a total of 2,504 D-models were built. On 18 November 1952, F-86D, 51-2945, set a record of 698.505 mph. Captain J. Slade Nash flew over a three km course at the Salton Sea in southern California at a height of only 125 ft. Another F-86D broke this record on 16 July 1953, when Lieutenant Colonel William F. Barns, flying F-86D 51-6145, in the same path of the previous flight. YF-95A prototype all-weather interceptor, two built, designation changed to YF-86D YF-86D originally designated YF-95A, F-86D Production interceptor originally designated F-95A,2,504 built.

Convair F-102 Delta Dagger
–
The Convair F-102 Delta Dagger was an American interceptor aircraft that was built as part of the backbone of the United States Air Forces air defenses in the late 1950s. Entering service in 1956, its purpose was to intercept invading Soviet strategic bomber fleets during the Cold War. Designed and manufactured by Convair,1,000 F-102s were built, a member of the Century Series, the F-102 was the USAFs first operational supersonic interceptor and delta-wing fighter. It used an internal weapons bay to carry guided missiles and rockets. As originally designed, it could not achieve Mach 1 supersonic flight until redesigned with area ruling, the F-102 replaced subsonic fighter types such as the Northrop F-89 Scorpion, and by the 1960s, it saw limited service in the Vietnam War in bomber escort and ground-attack roles. It was supplemented by McDonnell F-101 Voodoos and, later, by McDonnell Douglas F-4 Phantom IIs, the follow-on replacement was the Mach-2 Convair F-106 Delta Dart, which was an extensive redesign of the F-102. On 8 October 1948, the board of officers of the U. S. Four months later, on 4 February 1949, the USAF approved the recommendation, in November 1949, the Air Force decided that the new aircraft would be built around a fire-control system. The FCS was to be designed before the airframe to ensure compatibility, the airframe and FCS together were called the weapon system. In January 1950, the USAF Air Materiel Command issued request for proposals to 50 companies for the FCS, by May, the list was revised downward to 10. Following recommendations by the committee to the Saville Board, the proposals were further reduced to two competitors, Hughes Aircraft and North American Aviation. Although the Valley Committee thought it was best to award the contract to companies, Hughes was chosen by Saville and his team on 2 October 1950. Proposals for the airframe were issued on 18 June 1950, on 2 July 1954, three companies, Convair, Republic and Lockheed won the right to build a mockup. Until then, Convair had done research into delta-winged aircraft, experimenting with different designs, of the three, the best design was to win the production contract under the name Project MX-1554. In the end, Convair emerged as the victor with its design, designated XF-102, after Lockheed dropped out, the development of three different designs was too expensive and in November, only Convair was allowed to continue with its Model 8-80. To speed development, it was proposed to equip the prototypes, continued delays to the J67 and MA-1 FCS led to the decision to place an interim aircraft with the J40 and a simpler fire control system into production as the F-102A. The failure of the J40 led to the Pratt & Whitney J57 turbojet with afterburner, rated with 10,000 pounds-force of thrust being substituted for the prototypes, the F-102B would later evolve to become the F-106A, dubbed the Ultimate Interceptor. The prototype YF-102 made its first flight on 23 October 1953, at Edwards AFB, the second aircraft flew on 11 January 1954, confirming a dismal performance

Tactical Air Command
–
Tactical Air Command is an inactive United States Air Force organization. It was a Major Command of the United States Air Force, established on 21 March 1946 and headquartered at Langley Air Force Base and it was inactivated on 1 June 1992 and its personnel and equipment absorbed by Air Combat Command. Tactical Air Command was established to provide a balance between strategic, air defense, and tactical forces of the post–World War II U. S. Army Air Forces followed by, in 1947, the U. S. Air Force. In 1948, the Continental Air Command assumed control over air defense, tactical air, after two years in a subordinate role, Tactical Air Command was established as a major command. World War II showed the effectiveness of air power in supporting army ground forces. However, the demobilization in late 1945 meant that the huge air armada that had brought Germany to her knees. Following the end of World War II, Headquarters United States Army Air Forces had little funding and most wartime personnel had been released from active duty and returned to civilian life. Many USAAF aircraft were being sent to storage or scrapyards, although the tension with the Soviet Union meant that combat military air forces were still needed. The big questions were how large and what kind of forces, a major realignment of the USAAF was undertaken in early 1946. As part of the realignment, three major divisions within the Continental United States were formed, Strategic Air Command, Tactical Air Command. Each was given a specific responsibility, using assets prescribed to accomplish the assigned mission, Tactical Air Command was formed to command, organize, equip, train and administer assigned or attached forces. It was to plan for and participate in tactics for fighter, light bombardment and these included tactical fighters, tactical bombers, tactical missiles, troop carrier aircraft, assault, reconnaissance, and support units. TAC also planned for and developed the capability to deploy tactical striking forces anywhere in the world, during its existence, Tactical Air Command deployed personnel, material and/or aircraft to Asia, Africa, North America, South America, Europe and Australia in support of its prescribed mission. TACs original authorization was 25,500 officers and enlisted men, aircraft assets available consisted of propeller-driven North American P-51 Mustangs, Republic P-47 Thunderbolts and a handful of the new jet-powered Lockheed P-80 Shooting Stars. TAC was also given control of the Third Air Force, Ninth Air Force, on 18 September 1947, the United States Air Force was established as a separate military force, with TAC as one of its major commands. At the time, there was only one U. S. Air Forces in Europe tactical air unit available in Europe, TAC was called upon to send additional units and aircraft to Europe to reinforce the 86 FG. The 36th Fighter Group, flying Lockheed F-80B Shooting Stars, was transferred from Howard AFB in the Panama Canal Zone to Furstenfeldbruck Air Base near Munich. In addition to fighter aircraft, TAC also deployed available C-47 Skytrain transports to Europe, transferring them to USAFE

McDonnell Douglas F-4 Phantom II
–
It first entered service in 1960 with the U. S. Navy. Proving highly adaptable, it was adopted by the U. S. Marine Corps and the U. S. Air Force. The Phantom is a fighter with a top speed of over Mach 2.2. It can carry more than 18,000 pounds of weapons on nine hardpoints, including air-to-air missiles, air-to-ground missiles. The F-4, like other interceptors of its time, was designed without an internal cannon, later models incorporated an M61 Vulcan rotary cannon. Beginning in 1959, it set 15 world records for performance, including an absolute speed record. The Phantom has the distinction of being the last U. S. fighter flown to attain ace status in the 20th century. The F-4 Phantom II remained in use by the U. S. in the reconnaissance and Wild Weasel roles in the 1991 Gulf War, finally leaving service in 1996. It was also the aircraft used by both U. S. flight demonstration teams, the USAF Thunderbirds and the US Navy Blue Angels. The F-4 was also operated by the forces of 11 other nations. Israeli Phantoms saw extensive combat in several Arab–Israeli conflicts, while Iran used its fleet of Phantoms in the Iran–Iraq War. Phantoms remain in front line service with five countries, Phantom production ran from 1958 to 1981, with a total of 5,195 built, making it the most numerous American supersonic military aircraft. The F-4 is currently used by Greece, Iran, Japan, South Korea and it has been recently used in combat against the Islamic State. In 1952, McDonnells Chief of Aerodynamics, Dave Lewis, was appointed by CEO Jim McDonnell to be the preliminary design manager. With no new aircraft competitions on the horizon, internal studies concluded the Navy had the greatest need for a new and different aircraft type, in 1953, McDonnell Aircraft began work on revising its F3H Demon naval fighter, seeking expanded capabilities and better performance. The company developed several projects including a variant powered by a Wright J67 engine, the J79-powered version promised a top speed of Mach 1.97. On 19 September 1953, McDonnell approached the United States Navy with a proposal for the Super Demon, the Navy was sufficiently interested to order a full-scale mock-up of the F3H-G/H, but felt that the upcoming Grumman XF9F-9 and Vought XF8U-1 already satisfied the need for a supersonic fighter. On 26 May 1955, four Navy officers arrived at the McDonnell offices and, within an hour, because the Navy already had the Douglas A-4 Skyhawk for ground attack and F-8 Crusader for dogfighting, the project now had to fulfill the need for an all-weather fleet defense interceptor

Teton Dam
–
The Teton Dam was an earthen dam on the Teton River in Idaho, United States. It was built by the Bureau of Reclamation, one of eight federal agencies authorized to construct dams. Located in the part of the state, between Fremont and Madison counties, it suffered a catastrophic failure on June 5,1976. The collapse of the dam resulted in the deaths of 11 people and 13,000 cattle, the dam cost about $100 million to build, and the federal government paid over $300 million in claims related to its failure. Total damage estimates have ranged up to $2 billion, the dam has not been rebuilt. There had been interest in building a dam in the eastern Snake River Plain for many years to control spring runoff, the area had suffered a severe drought in 1961, followed by serious flooding in 1962. The Bureau of Reclamation proposed the Teton Dam in 1963, the planned dam was to be an earthen structure 310 feet high and 0.6 miles long and create a reservoir 17 miles in length. The impounded water would be used to generate hydroelectric power, an environmental impact statement was issued for the dam in 1971, but it did not raise the possibility of a collapse. The primary contractor for the dam was Morrison-Knudsen Co. of Boise, assisted by Peter Kiewit Sons Co. of Omaha, the $39 million contract was awarded in December 1971 and work began in 1972. The eastern Snake River Plain is almost entirely underlain by basalt erupted from large shield volcanos on top of rhyolitic ash-flow tuff, the tuff, a late-Cenozoic volcanic rock is 1.9 million years old. The dam site is composed of basalt and rhyolite, both of which are considered unsuitable for dam construction because of their high permeability and this was confirmed by long term pump-in tests at rates of 165 to 460 US gallons per minute. The widest fissures were determined to be 1.7 inches wide, the Bureau planned to seal these fissures by injecting grout into the rock under high pressure to create a grout curtain in the rock. The two largest, near-vertical fissures trend generally east-west and extend more than 100 feet below the bottom of the key trench, some of the fissures are lined by calcite, and rubble fills others. Several voids, as much as 6 inches wide, were encountered 60 to 85 feet below the surface beyond the right end of the dam. The largest fissures were actually enterable caves, one of them was eleven feet wide and a hundred feet long. Another one was nine feet wide in places and 190 feet long and these were not grouted because they were beyond the keyway trench and beyond the area where the Bureau had decided grouting was required. This necessitated using twice as much grouting as had originally anticipated –118,000 linear feet were used in total. The dam was completed in November 1975, and filling the reservoir began at the rate of 1 foot a day

1983 Borah Peak earthquake
–
The 1983 Borah Peak earthquake occurred on October 28 at 8,06,09 local time in the Lost River Range at Borah Peak in central Idaho, United States. The shock measured 6.9 on the moment magnitude scale and had a maximum Mercalli intensity of IX, the event is the largest and most significant to strike in the state of Idaho. Two children were killed by falling masonry while walking to school in Challis, about 120 miles northeast of Boise, twelve and a half million dollars in damage took place in the Challis-Mackay region. As a result of surface faulting, a maximum Mercalli intensity of IX was decided upon. The rupture caused clear surface faulting, a 21-mile long northwest-trending zone of fresh scarps and ground ruptures was present on a slope of the Lost River Range. Extensive breakage occurred along a 5-mile zone between West Spring and Cedar Creek, ground surface was literally shattered into tilted blocks, each several meters in width and these scarps were as broad as 330 feet. The Challis-Mackay region experienced rather thorough damage, with 11 commercial buildings and 39 homes sustaining damage while another 200 houses suffered minor to moderate damage. Mackay in particular, about 50 miles southeast of Challis, experienced the most severe damage, most of the citys large buildings on its Main Street were damaged, to some extent, eight of these buildings were deemed condemned and closed down. Most of these buildings were built from such as brick, concrete block. Near Chilly Buttes of Thousand Springs Valley, a series of artesian fountains/sand blows erupted immediately after the main shock, groundwater gushed from these fountains forming small craters and depositing aprons of light-colored sandy sediment around each crater.
