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

Massachusetts
–
It is bordered by the Atlantic Ocean to the east, the states of Connecticut and Rhode Island to the south, New Hampshire and Vermont to the north, and New York to the west. The state is named for the Massachusett tribe, which inhabited the area. The capital of Massachusetts and the most populous city in New England is Boston, over 80% of Massachusetts population lives in the Greater Boston metropolitan area, a region influential upon American history, academia, and industry. Originally dependent on agriculture, fishing and trade, Massachusetts was transformed into a manufacturing center during the Industrial Revolution, during the 20th century, Massachusetts economy shifted from manufacturing to services. Modern Massachusetts is a leader in biotechnology, engineering, higher education, finance. Plymouth was the site of the first colony in New England, founded in 1620 by the Pilgrims, in 1692, the town of Salem and surrounding areas experienced one of Americas most infamous cases of mass hysteria, the Salem witch trials. In 1777, General Henry Knox founded the Springfield Armory, which during the Industrial Revolution catalyzed numerous important technological advances, in 1786, Shays Rebellion, a populist revolt led by disaffected American Revolutionary War veterans, influenced the United States Constitutional Convention. In the 18th century, the Protestant First Great Awakening, which swept the Atlantic World, in the late 18th century, Boston became known as the Cradle of Liberty for the agitation there that led to the American Revolution. The entire Commonwealth of Massachusetts has played a commercial and cultural role in the history of the United States. Before the American Civil War, Massachusetts was a center for the abolitionist, temperance, in the late 19th century, the sports of basketball and volleyball were invented in the western Massachusetts cities of Springfield and Holyoke, respectively. Many prominent American political dynasties have hailed from the state, including the Adams, both Harvard University and the Massachusetts Institute of Technology, also in Cambridge, have been ranked among the most highly regarded academic institutions in the world. Massachusetts public school students place among the top nations in the world in academic performance, the official name of the state is the Commonwealth of Massachusetts. While this designation is part of the official name, it has no practical implications. Massachusetts has the position and powers within the United States as other states. Massachusetts was originally inhabited by tribes of the Algonquian language family such as the Wampanoag, Narragansett, Nipmuc, Pocomtuc, Mahican, and Massachusett. While cultivation of crops like squash and corn supplemented their diets, villages consisted of lodges called wigwams as well as longhouses, and tribes were led by male or female elders known as sachems. Between 1617 and 1619, smallpox killed approximately 90% of the Massachusetts Bay Native Americans, the first English settlers in Massachusetts, the Pilgrims, arrived via the Mayflower at Plymouth in 1620, and developed friendly relations with the native Wampanoag people. This was the second successful permanent English colony in the part of North America that later became the United States, the event known as the First Thanksgiving was celebrated by the Pilgrims after their first harvest in the New World which lasted for three days

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

104th Fighter Wing
–
The 104th Fighter Wing is a unit of the Massachusetts Air National Guard, stationed at Westfield-Barnes Regional Airport, Westfield, Massachusetts. If activated to service, the Wing is gained by the United States Air Force Air Combat Command. As commonwealth militia units, the units in the 104th Fighter Wing are not in the normal United States Air Force chain of command and they are under the jurisdiction of the Massachusetts National Guard unless they are federalized by order of the President of the United States. Specifically, the Wing is tasked to provide operationally ready combat units, combat support units and its goal is to organize, train and equip assigned personnel to provide an operationally ready squadron to the Air Combat Command that flies and fights successfully. As a result, the 131st Fighter-Interceptor Squadron at Barnes Municipal Airport was authorized to expand to a level. The 131st FIS becoming the flying squadron. Other squadrons assigned into the group were the 104th Headquarters, 104th Material Squadron, 104th Combat Support Squadron, the mission of the 104th Fighter Group was the air defense of Massachusetts. The 104th, along with the new 102d Fighter Group at Logan Airport, the air defense mission ended on 10 November 1958 when the Massachusetts Air Guard and its units were reassigned to Tactical Air Command and converted to F-86H Sabre fighter-bombers. During the 1950s and early 1960s, better training and equipment, during the summer of 1961, as the 1961 Berlin Crisis unfolded, the 131st TFS was notified on 16 August of its pending federalization and recall to active duty. On 1 October the 131st was federalized and assigned to the 102d Tactical Fighter Wing, the mission of the 102d TFW was to reinforce the United States Air Forces in Europe and deploy to Phalsbourg-Bourscheid Air Base, France. In France, the unit was to close air support to NATO ground forces. This involved keeping its aircraft on 24/7 alert, between 28 and 30 October, the 102d TFW departed Otis AFB for Phalsbourg. The wing deployed 82 F-86H Sabres, in addition 2 C-47 and 6 T-33 aircraft were assigned to the wing for support and training purposes. Starting on 5 December, the 102d began deploying to Wheelus Air Base Libya for gunnery training, during its time in Europe, the 102d participated in several USAF and NATO exercises, including a deployment to Leck Air Base, West Germany near the Danish border. At Leck, ground and support crews from both countries exchanged duties, learning how to perform maintenance and operational support tasks. On 7 May 1962, USAFE Seventeenth Air Force directed that the 102d TFW would deploy back to the United States during the summer, and the unit returned to the United States in July 1962. Regular USAF personnel, along with a group of ANG personnel who volunteered to remain on duty formed the 480th Tactical Fighter Squadron of the newly activated 366th Tactical Fighter Wing. The last of the ANG aircraft departing on 20 July, operational readiness inspections also honed the edges of the wing

McDonnell Douglas F-15 Eagle
–
The McDonnell Douglas F-15 Eagle is an American twin-engine, all-weather tactical fighter aircraft designed by McDonnell Douglas to gain and maintain air supremacy in aerial combat. Following reviews of proposals, the United States Air Force selected McDonnell Douglas design in 1967 to meet the services need for an air superiority fighter. The Eagle first flew in July 1972, and entered service in 1976 and it is among the most successful modern fighters, with over 100 victories and no losses in aerial combat, with the majority of the kills scored by the Israel Air Force. The Eagle has been exported to Israel, Japan, and Saudi Arabia, the F-15 was originally envisioned as a pure air superiority aircraft. Its design included a secondary ground-attack capability that was largely unused, the aircraft design proved flexible enough that an all-weather strike derivative, the F-15E Strike Eagle, was later developed and entered service in 1989. The F-15 Eagle is expected to be in service with the U. S. Air Force past 2025, newer models are still being produced for foreign users. The F-15 production line is set to end in 2019,47 years after the types first flight. The F-15 can ultimately trace its origins to the Vietnam War, when the U. S. Air Force, at the time, Defense Secretary Robert McNamara was pressing for both services to use as many common aircraft as possible, even if there were performance sacrifices involved. The former were capable in the tactical role, while the latter might be less so. If the Air Force did choose a design, maintaining air superiority would be a top priority. The next month, a report on light tactical aircraft suggested the Air Force purchase the F-5 or A-7 and this point was reinforced after the loss of two Republic F-105 Thunderchief aircraft to obsolete MiG-15s or MiG-17s on 4 April 1965. In April 1965, Harold Brown, at that time director of the DDR&E, stated the position was to consider the F-5. On 1 August, Gabriel Disosway took command of Tactical Air Command and reiterated calls for the F-X, an official requirements document was finalized in October, and sent out as a request for proposals to 13 companies on 8 December 1965. Following a downselect, four companies were asked to further developments. In total, they developed some 500 design concepts, typical designs featured variable-sweep wings, weighed over 60,000 pounds, included a top speed of Mach 2.7 and a thrust-to-weight ratio of 0.75. When the proposals were studied in July 1966, the aircraft were roughly the size and weight of the TFX, and like that aircraft, through this period, studies of combat over Vietnam were producing worrying results. Previous doctrine had stressed long-range combat using missiles, and optimized aircraft for this role, the result was highly loaded aircraft with large radars and excellent speed, but limited maneuverability and often lacking a gun. In early 1967, they proposed that the design had a thrust-to-weight ratio of near 1,1, a maximum speed further reduced to Mach 2.3, a weight of 40,000 pounds

Bellows Air Force Station
–
Bellows Air Force Station is a United States military reservation located in Waimanalo, Hawaii. Bellows AFS is operated by Detachment 2, 18th Force Support Squadron of the 18th Mission Support Group based at Kadena Air Force Base, Okinawa, located on the opposite side of Oahu is the similar Pililaau Army Recreation Center, part of the Armed Forces Recreation Centers system. Created in 1917 as the Waimanalo Military Reservation, the base was renamed Bellows Field in 1933 after Lt. Franklin Barney Bellows, a World War I war hero. Bellows Field was made a permanent military post in July 1941, Bellows Field was used for recreational gliders in the late 1950s and early 1960s. In this way the pilot could keep the glider in the air as long as desired, Bellows AFS was also the Air Force transmitter facility site for long haul HF radio communications from the late 1950s until HF radio was largely replaced by the military satellite program. HF radio links were established using highly directional Sloping V antennas to Clark Air Base, Philippines, message circuits were originated or relayed at Hickam AFB, near Pearl Harbor, and sent to Bellows for re-transmission over the HF systems. The receiver site was separated from the transmitter site to prevent RF interference from the high power transmitters. In 1958, when the last runways were closed and the flying field status terminated, as a Recreation Center, Bellows AFS provides beachfront cabins, camping, and limited condominium style apartments for active duty, reserve, and retired military personnel to stay in. Additionally, there is a small AAFES Express shopette, a paintball course, the Marine Corps acquired approximately 1,049 acres of Bellows from the Air Force in 1999. The Marine Corps Training Area Bellows is now part of Marine Corps Base Hawaii, MCTAB adds significant training capabilities and maneuver space for non-live fire military training activities. The Marines and other services use the areas to conduct amphibious, helicopter. It is currently the only place in Hawaii where amphibious landings can transition directly into maneuver training areas for extremely military training. Recent improvements to the area over the old runway include construction of a forward operating base mock-up around the old Bldg. 700 renovations, and a military operations in urban terrain training system that consists of 74 buildings on four separate sites. Additional containers have been moved into the training area to be used as part of a combat vehicle operators course for Marines to simulate driving in real-world conditions. The 298th Regiment, Multi-Functional Training Unit, Regional Training Institute is part of the Armys Training, the headquarters and 1st and 2nd Battalions are located at Bellows Air Force Station in Waimanalo, Hawaii. The Ordnance Training Company is located at the Regional Training Site Maintenance facilities in Pearl City, Hawaii World War II Army Airfields Bellows Air Force Station Homepage Bellows Air Force Station at GlobalSecurity. org

Bell P-39 Airacobra
–
The Bell P-39 Airacobra was one of the principal American fighter aircraft in service when the United States entered World War II. The P-39 was used by the Soviet Air Force, which scored the highest number of individual kills attributed to any U. S. fighter type in the Eastern European theatre. Other major users of the type included the Free French, the Royal Air Force, the United States Army Air Forces, and the Italian Co-Belligerent Air Force. Designed by Bell Aircraft, it had a layout, with the engine installed in the center fuselage, behind the pilot. It was also the first fighter fitted with a tricycle undercarriage, although its mid-engine placement was innovative, the P-39 design was handicapped by the absence of an efficient turbo-supercharger, preventing it from performing high-altitude work. As such it was rejected by the RAF for use over western Europe but adopted by the USSR where most air combat took place at medium, together with the derivative P-63 Kingcobra, the P-39 was one of the most successful fixed-wing aircraft manufactured by Bell. It was a request for a single-engine high-altitude interceptor having the mission of interception. Despite being called an interceptor, the aircrafts role was simply an extension of the traditional pursuit role, using a heavier. This was the most demanding set of fighter specifications USAAC had presented to that date and this happened because H. M. Poyer, designer for project leader Robert Woods, was impressed by the power of this weapon and pressed for its incorporation. This was unusual, because fighter design had previously driven by the intended engine. Although devastating when it worked, the T9 had very limited ammunition, a low rate of fire, a secondary benefit of the mid-engine arrangement was that it created a smooth and streamlined nose profile. Much was made of the fact that this resulted in a configuration “with as trim, entry to the cockpit was through side doors rather than a sliding canopy. There were no problems with propeller shaft failure, the XP-39 made its maiden flight on 6 April 1938. At Wright Field, Ohio, achieving 390 mph at 20,000 ft, however, the XP-39 was found to be short on performance at altitude. Flight testing had found its top speed at 20,000 feet to be lower than the 400 mph claimed in the original proposal, as originally specified by Kelsey and Saville, the XP-39 had a turbo-supercharger to augment its high-altitude performance. Bell cooled the turbo with a scoop on the side of the fuselage. Kelsey wished to shepherd the XP-39 through its early engineering teething troubles, the XP-39 project was handed over to others, and in June 1939 the prototype was ordered by General Henry H. Arnold to be evaluated in NACA wind tunnels to find ways of increasing its speed, tests were carried out, and Bell engineers followed the recommendations of NACA and the Army to reduce drag such that the top speed was increased 16%

Thirteenth Air Force
–
The Thirteenth Air Force was a numbered air force of the United States Air Force Pacific Air Forces. It was last headquartered at Hickam Air Force Base on the island of Oahu,13 AF has never been stationed in the continental United States. It was one of the oldest continuously active numbered air forces in the United States Air Force. Established on 14 December 1942 at Plaine Des Gaiacs Airfield, on New Caledonia,13 AF was a United States Army Air Forces combat air force deployed to the Pacific Theater of World War II. During the Cold War,13 AF remained in the Philippines, providing air defense of the nation, during the Korean War, its units provided staging areas for people and equipment destined for the war zone. 13 AF units last engaged in combat during the SS Mayaguez Incident in May 1975 and it was inactivated on 28 September 2012 and its functions merged with PACAF. The command is charged with planning, executing, and assessing operations in support of the U. S. On behalf of the Pacific Air Forces commander, the 13th AF commander is positioned to command Air Force forces, combined or joint force air components, Antarctic Program through Operation Deep Freeze. Headquarters,13 AF is made up of an A-staff, personal staff, 613th Air and Space Operations Center, known as the Maj Richard Bong AOC, the 613th AOC is one of the U. S. The AOC serves as the center of air operations during any campaign. Thirteenth AF relocated and officially established its headquarters at Andersen AFB, Guam, the command was moved from Guam to Hickam AFB in May 2005. It also includes a squadron of Lockheed F-22s, finally it serves as an important en-route location for transient aircraft. 36th Wing, Andersen AFB, Guam The 36th WG has a mission to support global projection. On 5 January 2007, Detachment 1,13 AF was activated at Yokota AB, the 13th Air Expeditionary Group, and formerly the 500th Air Expeditionary Group, is activated seasonally to support Operation Deep Freeze in the Antarctic. Thirteenth Air Force has never been stationed in the continental United States, it is one of the oldest, continuously active. It engaged in combat in the Pacific Theater during World War II, since World War II, it has provided air defense in the Far East, primarily the Philippines, until the 1991 eruption of Mt. Pinatubo forced the closure of Clark AB. Numerous Thirteenth Air Force organizations participated in Southeast Asia combat operations in the 1960s and 1970s, established as Thirteenth Air Force on 14 December 1942 Activated on 13 January 1943 U. S. Served in combat with Thirteenth AF until the end of the war, inactivated in the Philippines on 15 March 1946

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

Pacific Ocean
–
The Pacific Ocean is the largest and deepest of the Earths oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west, the Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 metres. Both the center of the Water Hemisphere and the Western Hemisphere are in the Pacific Ocean, the oceans current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favourable winds on reaching the ocean. He called it Mar Pacífico, which in both Portuguese and Spanish means peaceful sea, important human migrations occurred in the Pacific in prehistoric times. Long-distance trade developed all along the coast from Mozambique to Japan, trade, and therefore knowledge, extended to the Indonesian islands but apparently not Australia. By at least 878 when there was a significant Islamic settlement in Canton much of trade was controlled by Arabs or Muslims. In 219 BC Xu Fu sailed out into the Pacific searching for the elixir of immortality, from 1404 to 1433 Zheng He led expeditions into the Indian Ocean. The east side of the ocean was discovered by Spanish explorer Vasco Núñez de Balboa in 1513 after his expedition crossed the Isthmus of Panama and he named it Mar del Sur because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. Later, Portuguese explorer Ferdinand Magellan sailed the Pacific East to West on a Castilian expedition of world circumnavigation starting in 1519, Magellan called the ocean Pacífico because, after sailing through the stormy seas off Cape Horn, the expedition found calm waters. The ocean was often called the Sea of Magellan in his honor until the eighteenth century, sailing around and east of the Moluccas, between 1525 and 1527, Portuguese expeditions discovered the Caroline Islands, the Aru Islands, and Papua New Guinea. In 1542–43 the Portuguese also reached Japan, in 1564, five Spanish ships consisting of 379 explorers crossed the ocean from Mexico led by Miguel López de Legazpi and sailed to the Philippines and Mariana Islands. The Manila galleons operated for two and a half centuries linking Manila and Acapulco, in one of the longest trade routes in history, Spanish expeditions also discovered Tuvalu, the Marquesas, the Cook Islands, the Solomon Islands, and the Admiralty Islands in the South Pacific. In the 16th and 17th century Spain considered the Pacific Ocean a Mare clausum—a sea closed to other naval powers, as the only known entrance from the Atlantic the Strait of Magellan was at times patrolled by fleets sent to prevent entrance of non-Spanish ships. On the western end of the Pacific Ocean the Dutch threatened the Spanish Philippines, Spain also sent expeditions to the Pacific Northwest reaching Vancouver Island in southern Canada, and Alaska. The French explored and settled Polynesia, and the British made three voyages with James Cook to the South Pacific and Australia, Hawaii, and the North American Pacific Northwest, one of the earliest voyages of scientific exploration was organized by Spain in the Malaspina Expedition of 1789–1794. It sailed vast areas of the Pacific, from Cape Horn to Alaska, Guam and the Philippines, New Zealand, Australia, and the South Pacific. Growing imperialism during the 19th century resulted in the occupation of much of Oceania by other European powers, and later, Japan, in Oceania, France got a leading position as imperial power after making Tahiti and New Caledonia protectorates in 1842 and 1853 respectively. After navy visits to Easter Island in 1875 and 1887, Chilean navy officer Policarpo Toro managed to negotiate an incorporation of the island into Chile with native Rapanui in 1888, by occupying Easter Island, Chile joined the imperial nations

Iwo Jima
–
The U. S. occupied Iwo Jima until 1968 when it was returned to Japan. The first European to arrive at Iwo Jima was Spanish sailor Bernardo de la Torre who named it Sufre Island, at that time Iwo Jima and other islands were the limit between the Spanish and Portuguese Empires in the far East. In 1779, the island was charted as Sulphur Island, the translation of its official name. The name Sulphur Island was translated into Late Middle Japanese with the Sino-Japanese rendering iwau-tau, from Middle Chinese ljuw-huang sulfur, the historical spelling iwautau had come to be pronounced Iwō-tō by the age of Western exploration, and the 1946 orthography reform fixed the spelling and pronunciation at Iō-tō. An alternative, Iwō-jima, modern Iō-jima, also appeared in nautical atlases, tō and shima are different readings of the kanji for island, the shima being changed to jima in this case. Japanese naval officers who arrived to fortify the island before the U. S. invasion mistakenly called it Iwo Jima, in this way, the Iwo Jima reading became mainstream and was the one used by U. S. forces who arrived during World War II. Moves to revert the pronunciation were sparked by the high-profile films Flags of Our Fathers and Letters from Iwo Jima, the change does not affect how the name is written with kanji, 硫黄島, only how it is pronounced or written in hiragana, katakana and rōmaji. The island has an area of 21 km2. The most prominent feature is Mount Suribachi on the southern tip, named after a Japanese grinding bowl, the summit of Mount Suribachi is the highest point on the island. Iwo Jima is unusually flat and featureless for a volcanic island, Suribachi is the only obvious volcanic feature, as it is only the resurgent dome of a larger submerged volcanic caldera. 80 km north of the island is North Iwo Jima and 59 kilometres south is South Iwo Jima, just south of Minami-Iō-jima are the Mariana Islands. Iwo Jima has a history of volcanic activity a few times per year. Late 1779, Captain Cooks surveying crew landed on a beach which is now 40 m above sea level due to volcanic uplifting. Such uplifting occurs on the island at a rate of between 100 and 800 mm per year, with an average rate of 200 mm per year. Early 1945, USA armed forces landed on a beach which as of 2015 was 17 metres above sea level due to volcanic uplift,28 March 1957, Phreatic eruption without warning 2 km northeast of Suribachi, lasted 65 minutes and ejected material 30 m high from one crater. Another crater,30 m wide and 15 m deep, formed by collapse 50 minutes after the eruption ended,31 March 1957, Gas emissions increased. 9-10 March 1982,5 phreatic eruptions from vents on the northwest shore of Iwo-jima,21 September 2001, Submarine eruption from 3 vents southeast of Iwo-jima. It built a 10 m diameter pyroclastic cone,19 October 2001, A small phreatic eruption at Idogahama, made a crater 10 m wide and 2–3 m deep

Boeing B-29 Superfortress
–
The Boeing B-29 Superfortress is a four-engine propeller-driven heavy bomber designed by Boeing which was flown primarily by the United States during World War II and the Korean War. It was one of the largest aircraft operational during World War II and it was the single most expensive weapons project undertaken by the United States in World War II, exceeding the cost of the Manhattan Project by between 1 and 1.7 billion dollars. A manned tail gun installation was semi-remote, the name Superfortress continued the pattern Boeing started with its well-known predecessor, the B-17 Flying Fortress. Designed for the strategic bomber role, the B-29 also excelled in low-altitude nighttime incendiary bombing missions. One of the B-29s final roles during World War II was carrying out the bomb attacks on Hiroshima. The B-29 served in roles throughout the 1950s. The Royal Air Force flew the B-29 as the Washington until phasing out the type in 1954, the Soviet Union produced an unlicensed reverse-engineered copy as the Tupolev Tu-4. The B-29 was the progenitor of a series of Boeing-built bombers, transports, tankers, reconnaissance aircraft, the type was retired in the early 1960s. The B-29 production total was 3,970 aircraft, dozens of B-29s remain as static displays but only two examples, Fifi and Doc, have been restored to flying status, with Doc flying again for the first time from McConnell AFB on July 17,2016. A transport developed from the B-29 was the Boeing C-97 Stratofreighter, first flown in 1944, followed by its commercial airliner variant and this bomber-to-airliner derivation was similar to the B-17/Model 307 evolution. In 1948 Boeing introduced a variant of the B-29 as the KB-29. A heavily modified line of outsized-cargo variants of the Stratocruiser is the Guppy / Mini Guppy / Super Guppy which remain in service today with operators including NASA, Boeing began work on pressurized long-range bombers in 1938, in response to a United States Army Air Corps request. Boeings design study for the Model 334 was a derivative of the Boeing B-17 Flying Fortress with nosewheel undercarriage. Although the Air Corps did not have money to pursue the design, in April 1939, Charles Lindbergh convinced general Henry H. Arnold to produce a new bomber in large numbers to counter the Nazi production, Boeings previous private venture studies formed the starting point for its response to this specification. Boeing submitted its Model 345 on 11 May 1940, in competition with designs from Consolidated Aircraft, Lockheed, Consolidated continued to work on its Model 33 as it was seen by the Air Corps as a backup in case of problems with Boeings design. Boeing received a production order for 14 service test aircraft and 250 production bombers in May 1941. The B-29 featured a design with circular cross-section for strength
