McDonnell Douglas
–
McDonnell Douglas was a major American aerospace manufacturing corporation and defense contractor formed by the merger of McDonnell Aircraft and the Douglas Aircraft Company in 1967. Between then and its own merger with Boeing in 1997, it produced a number of commercial and military aircraft such as the DC-10 airliner. The corporation was based at Lambert–St, the company was formed from the firms of James Smith McDonnell and Donald Wills Douglas in 1967. Both men were of Scottish ancestry, graduates of MIT and had worked for the aircraft manufacturer Glenn L. Martin Company, Douglas had been chief engineer at Martin before leaving to establish Davis-Douglas Company in early 1920 in Los Angeles. He bought out his backer and renamed the firm the Douglas Aircraft Company in 1921, McDonnell & Associates in Milwaukee, Wisconsin in 1926. His idea was to produce an aircraft for family use. The economic depression from 1929 ruined his ideas and the company collapsed and he worked at three companies with the final being Glenn Martin Company in 1933. He left Martin in 1938 to try again with his own firm, McDonnell Aircraft Corporation, World War II was a major earner for Douglas. The company produced almost 30,000 aircraft from 1942 to 1945, both companies suffered at the end of hostilities, facing an end of government orders and a surplus of aircraft. After the war Douglas continued to new aircraft, including the DC-6 in 1946. The company moved into jet propulsion, producing its first for the military – the conventional F3D Skyknight in 1948, in 1955, Douglas introduced the first attack jet of the United States Navy with the A4D Skyhawk. Designed to operate from the decks of the World War II Essex class aircraft carriers, the Skyhawk was small, reliable, variants of it continued in use in the Navy for almost 50 years, finally serving in large numbers in a two-seat version as a jet trainer. Douglas also made commercial jets, producing the DC-8 in 1958 to compete with the Boeing 707, the Korean War-era Banshee and later the F-4 Phantom II produced during the Vietnam War helped push McDonnell into a major military fighter supply role. Douglas created a series of experimental high-speed jet aircraft in the Skyrocket family, Douglas also gained contracts from NASA, notably for part of the enormous Saturn V rocket. The two companies were now major employers, but both were having problems, Douglas was strained by the cost of the DC-8 and DC-9, while McDonnell suffered lean times during any downturns in military procurement. The two companies began to sound each other out about a merger, inquiries began in 1963, Douglas offered bid invitations from December 1966 and accepted that of McDonnell. The two firms were merged on 28 April 1967 as the McDonnell Douglas Corporation. The two companies were a fit for each other

Santa Monica, California
–
Santa Monica is a beachfront city in western Los Angeles County, California, United States. The Census Bureau population for Santa Monica in 2010 was 89,736, due in part to an agreeable climate, Santa Monica became a famed resort town by the early 20th century. The city has experienced a boom since the late 1980s through the revitalization of its core, significant job growth. The Santa Monica Pier remains a popular and iconic destination, Santa Monica was long inhabited by the Tongva people. Santa Monica was called Kecheek in the Tongva language, the first non-indigenous group to set foot in the area was the party of explorer Gaspar de Portolà, who camped near the present-day intersection of Barrington and Ohio Avenues on August 3,1769. Named after the Christian saint Monica, there are two different accounts of how the name came to be. One says it was named in honor of the feast day of Saint Monica, another version says it was named by Juan Crespí on account of a pair of springs, the Kuruvungna Springs, that were reminiscent of the tears Saint Monica shed over her sons early impiety. In Los Angeles, several battles were fought by the Californios, following the Mexican–American War, Mexico signed the Treaty of Guadalupe Hidalgo, which gave Mexicans and Californios living in state certain unalienable rights. US government sovereignty in California began on February 2,1848, in the 1870s the Los Angeles and Independence Railroad, connected Santa Monica with Los Angeles, and a wharf out into the bay. The first town hall was a modest 1873 brick building, later a beer hall and it is Santa Monicas oldest extant structure. By 1885, the towns first hotel was the Santa Monica Hotel, around the start of the 20th century, a growing population of Asian Americans lived in and around Santa Monica and Venice. A Japanese fishing village was near the Long Wharf while small numbers of Chinese lived or worked in Santa Monica, the two ethnic minorities were often viewed differently by White Americans who were often well-disposed towards the Japanese but condescending towards the Chinese. The Japanese village fishermen were an economic part of the Santa Monica Bay community. Donald Wills Douglas, Sr. built a plant in 1922 at Clover Field for the Douglas Aircraft Company, in 1924, four Douglas-built planes took off from Clover Field to attempt the first aerial circumnavigation of the world. Two planes returned after covering 27,553 miles in 175 days, the Douglas Company kept facilities in the city until the 1960s. The Great Depression hit Santa Monica deeply, one report gives citywide employment in 1933 of just 1,000. Hotels and office building owners went bankrupt, in the 1930s, corruption infected Santa Monica. The federal Works Project Administration helped build several buildings, most notably City Hall, the main Post Office and Barnum Hall were also among other WPA projects

Long Beach, California
–
Long Beach is the 36th most populous city in the United States and the 7th most populous in California. It is located on the Pacific Coast of the United States, as of 2010, its population was 462,257. Long Beach is the second largest city in the Los Angeles metropolitan area, the Port of Long Beach is the second busiest container port in the United States and is among the worlds largest shipping ports. The city also maintains a progressively declining oil industry with minor wells located both directly beneath the city as well as offshore, manufacturing sectors include those in aircraft, automotive parts, electronic equipment, audiovisual equipment, petrochemicals, precision metals and home furnishings. Long Beach lies in the corner of Los Angeles County. Downtown Long Beach is approximately 22 miles south of Downtown Los Angeles, indigenous people have lived in coastal Southern California for over 10,000 years, and several successive cultures have inhabited the present-day area of Long Beach. By the 16th-century arrival of Spanish explorers, the dominant group were the Tongva people and they had at least three major settlements within the present-day city. Tevaaxaanga was a settlement near the Los Angeles River, while Ahwaanga and Povuunga were coastal villages. Along with other Tongva villages, they were forced to relocate in the century due to missionization, political change. In 1784 the Spanish Empires King Carlos III granted Rancho Los Nietos to Spanish soldier Manuel Nieto, the Rancho Los Cerritos and Rancho Los Alamitos were divided from this territory. The boundary between the two ran through the center of Signal Hill on a southwest to northeast diagonal. A portion of western Long Beach was originally part of the Rancho San Pedro and its boundaries were in dispute for years, due to flooding changing the Los Angeles River boundary, between the ranchos of Juan Jose Dominguez and Manuel Nieto. In 1843 Jonathan Temple bought Rancho Los Cerritos, having arrived in California in 1827 from New England and he built what is now known as the Los Cerritos Ranch House, a still-standing adobe which is a National Historic Landmark. Temple created a cattle ranch and prospered, becoming the wealthiest man in Los Angeles County. Both Temple and his house played important local roles in the Mexican–American War. On an island in the San Pedro Bay, Mormon pioneers made an attempt to establish a colony. Two years previous Flint, Bixby & Co had also purchased along with Northern California associate James Irvine, to manage Rancho Los Cerritos, the company selected Lewellyns brother Jotham Bixby, the Father of Long Beach. Three years later Bixby bought into the property and would form the Bixby Land Company

Aircraft
–
An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the lift of an airfoil. The human activity that surrounds aircraft is called aviation, crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as type, aircraft propulsion, usage. Each of the two World Wars led to technical advances. Consequently, the history of aircraft can be divided into five eras, Pioneers of flight, first World War,1914 to 1918. Aviation between the World Wars,1918 to 1939, Second World War,1939 to 1945. Postwar era, also called the jet age,1945 to the present day, aerostats use buoyancy to float in the air in much the same way that ships float on the water. They are characterized by one or more large gasbags or canopies, filled with a relatively low-density gas such as helium, hydrogen, or hot air, which is less dense than the surrounding air. When the weight of this is added to the weight of the aircraft structure, a balloon was originally any aerostat, while the term airship was used for large, powered aircraft designs – usually fixed-wing. In 1919 Frederick Handley Page was reported as referring to ships of the air, in the 1930s, large intercontinental flying boats were also sometimes referred to as ships of the air or flying-ships. – though none had yet been built, the advent of powered balloons, called dirigible balloons, and later of rigid hulls allowing a great increase in size, began to change the way these words were used. Huge powered aerostats, characterized by an outer framework and separate aerodynamic skin surrounding the gas bags, were produced. There were still no fixed-wing aircraft or non-rigid balloons large enough to be called airships, then several accidents, such as the Hindenburg disaster in 1937, led to the demise of these airships. Nowadays a balloon is an aerostat and an airship is a powered one. A powered, steerable aerostat is called a dirigible, sometimes this term is applied only to non-rigid balloons, and sometimes dirigible balloon is regarded as the definition of an airship. Non-rigid dirigibles are characterized by a moderately aerodynamic gasbag with stabilizing fins at the back and these soon became known as blimps. During the Second World War, this shape was adopted for tethered balloons, in windy weather

Southern California
–
Southern California, often abbreviated as SoCal, is a geographic and cultural region that generally comprises Californias 10 southernmost counties. The region is described as eight counties, based on demographics and economic ties, Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara. The more extensive 10-county definition, which includes Kern and San Luis Obispo counties, is used and is based on historical political divisions. Southern California is an economic center for the state of California. The 8-county and 10-county definitions are not used for the greater Southern California Megaregion, the megaregions area is more expansive, extending east into Las Vegas, Nevada and south across the Mexican border into Tijuana.5 million people. With over 22 million people, Southern California contains roughly 60 percent of Californias population, located east of Southern California is the Colorado Desert and the Colorado River at the border with Arizona. The Mojave Desert is located at the border with the state of Nevada while towards the south is the Mexico–United States border, within Southern California are two major cities, Los Angeles and San Diego, as well as three of the countrys largest metropolitan areas. With a population of 3,792,621, Los Angeles is the most populous city in California and the second most populous in the United States. South of Los Angeles and with a population of 1,307,402 is San Diego, the second most populous city in the state and the eighth most populous in the nation. The counties of Los Angeles, Orange, San Diego, San Bernardino, and Riverside are the five most populous in the state, the motion picture, television, and music industry are centered in the Los Angeles area in Southern California. Hollywood, a district within Los Angeles, gives its name to the American motion picture industry, headquartered in Southern California are The Walt Disney Company, Sony Pictures, Universal, MGM, Paramount Pictures, 20th Century Fox, and Warner Brothers. Universal, Warner Brothers, and Sony also run major record companies, Southern California is also home to a large homegrown surf and skateboard culture. Companies such as Vans, Volcom, Quiksilver, No Fear, RVCA, some of the worlds biggest action sports events, including the X Games, Boost Mobile Pro, and the U. S. Open of Surfing, are all held in Southern California. Southern California is also important to the world of yachting, the annual Transpacific Yacht Race, or Transpac, from Los Angeles to Hawaii, is one of yachtings premier events. The San Diego Yacht Club held the Americas Cup, the most prestigious prize in yachting, from 1988 to 1995, Southern California is home to many sports franchises and sports networks such as Fox Sports Net. Many locals and tourists frequent the Southern California coast for its popular beaches, the desert city of Palm Springs is popular for its resort feel and nearby open spaces. Southern California is not a geographic designation and definitions of what constitutes Southern California vary. Geographically, Californias North-South midway point lies at exactly 37°958.23 latitude, around 11 miles south of San Jose, however, when the state is divided into two areas, the term Southern California usually refers to the 10 southernmost counties of the state

Boeing
–
The Boeing Company is an American multinational corporation that designs, manufactures, and sells airplanes, rotorcraft, rockets, and satellites worldwide. The company also provides leasing and product support services, Boeing stock is a component of the Dow Jones Industrial Average. The Boeing Companys corporate headquarters are located in Chicago and the company is led by President, Boeing is organized into five primary divisions, Boeing Commercial Airplanes, Boeing Defense, Space & Security, Engineering, Operations & Technology, Boeing Capital, and Boeing Shared Services Group. Boeing bought Heaths shipyard in Seattle on the Duwamish River, which became his first airplane factory. Boeing was incorporated in Seattle by William Boeing, on July 15,1916, Boeing was later incorporated in Delaware, the original Certificate of Incorporation was filed with the Secretary of State of Delaware on July 19,1934. Boeing, who studied at Yale University, worked initially in the timber industry and this knowledge proved invaluable in his subsequent design and assembly of airplanes. The company stayed in Seattle to take advantage of the supply of spruce wood. William Boeing founded his company a few months after the June 15 maiden flight of one of the two B&W seaplanes built with the assistance of George Conrad Westervelt, a U. S. Navy engineer. Boeing and Westervelt decided to build the B&W seaplane after having flown in a Curtiss aircraft, Boeing bought a Glenn Martin Flying Birdcage seaplane and was taught to fly by Glenn Martin himself. Boeing soon crashed the Birdcage and when Martin informed Boeing that replacement parts would not become available for months, Westervelt agreed to build a better airplane and soon produced the B&W Seaplane. This first Boeing airplane was assembled in a hangar located on the northeast shore of Seattles Lake Union. Many of Boeings early planes were seaplanes, on April 6,1917, the U. S. declared War on Germany and later in the year entered World War I. On May 9,1917, the became the Boeing Airplane Company. With the U. S. entering the war, Boeing knew that the U. S. Navy needed seaplanes for training, so Boeing shipped two new Model Cs to Pensacola, Florida, where the planes were flown for the Navy. The Navy liked the Model C and ordered 50 more, the company moved its operations to a larger former shipbuilding facility known as Boeing Plant 1, located on the lower Duwamish River, Washington state. Others, including Boeing, started selling other products, Boeing built dressers, counters, and furniture, along with flat-bottom boats called Sea Sleds. In 1919 the Boeing B-1, flying boat made its first flight and it accommodated one pilot and two passengers and some mail. Over the course of eight years, it made international airmail flights from Seattle to Victoria, on May 24,1920, the Boeing Model 8 made its first flight

First aerial circumnavigation
–
The first aerial circumnavigation of the world was conducted in 1924 by a team of aviators of the United States Army Air Service, the precursor of the United States Air Force. The trip took 175 days, covering over 27,553 miles, in the early 1920s several countries were vying to be the first to fly around the world. The British had made one unsuccessful around-the-world air flight attempt in 1922, the following year, a French team had tried, the Italians, Portuguese, and British also announced plans for a world-circling flight. In the spring of 1923, the U. S. Army Air Service became interested in having a squadron of military aircraft undertake a round-the-world flight. It assigned a group of officers in the War Department planning group, the War Department instructed the Air Service to look at both the Fokker T-2 transport and the Davis-Douglas Cloudster to see if either would be suitable and to acquire examples for testing. Although deemed satisfactory, the group considered other U. S. S. The DT-2 had proven to be an aircraft that could accommodate interchangeable wheeled. Since the aircraft was a model, Douglas stated that a new aircraft. The Air Service agreed and sent Lieutenant Erik Henning Nelson, a member of the planning group, Douglas, assisted by Jack Northrop, began to modify a DT-2 to suit the circumnavigation requirements. The main modification involved its fuel capacity, all the internal bomb carrying structures were removed with additional fuel tanks added to the wings and fuselage fuel tanks enlarged in the aircraft. The total fuel capacity went from 115 gallons to 644 gallons, Lieutenant Nelson took the Douglas proposal to Washington where Major General Mason M. Patrick, Chief of the Air Service, approved it on 1 August 1923. The War Department awarded a contract to Douglas for the construction of a single prototype. The prototype met all expectations, and a contract was awarded for four production aircraft. The last DWC was delivered on 11 March 1924, the spare parts included 15 extra Liberty engines,14 extra sets of pontoons, and enough replacement airframe parts for two more aircraft. These spare parts were sent ahead to locations along the route around the world the aircraft planned to follow, Seattle, Maj. Frederick Martin and SSgt. Alva Harvey Chicago, Lt. Lowell H. Smith and 1st Lt. Leslie P, Arnold Boston /Boston II, 1st Lt. Leigh P. Wade and SSgt. Ogden New Orleans, Lt. Erik Nelson and Lt. Jack Harding The pilots trained in meteorology and navigation at Langley Field in Virginia, the crews then practiced on the production aircraft in Los Angeles and San Diego. Four aircraft, Seattle, Chicago, Boston, and New Orleans, left Santa Monica, California, on 4 April 1924, for Sand Point, Washington, near Seattle, Washington, on 6 April 1924, they left Seattle for Alaska

The population was 39,018 at the 2010 census, located on the Mississippi River, it is one of the Quad Cities, along with neighboring Moline, East Moline, and the Iowa cities of Davenport and Bettendorf. The Quad Cities has a population of about 380,000, the city is home to Rock Island Arsenal, the largest government-owned weapons manufacturing arsenal in the US, which employs 6,000 people. Theres a wide variety of housing available in Rock Island including historic homes, new downtown condos, new construction in the heart of the city, the Rock Island-Milan School District, Rockridge School District along with private schools, serve the city. The District has art galleries and theaters, nightclubs and coffee shops, golf courses, parks, a casino, botanical center, marina, historic tours, bike paths, and festivals offer entertainment opportunities. In 2015 Rock Island was ranked the 32nd Best Small City in the based on economic health, affordability. Rock Island made the list of the nations 25 Most Affordable Housing Markets and this area has been a fortuitous place first for settlement and then for steamboat traffic, bridges, and railroads. Various Native American tribes occupied this area for thousands of years before settlement, by the early nineteenth century, it was occupied chiefly by the historic Sauk tribe. Their major village of Saukenuk was located on the side of Rock Island. After the War of 1812, the United States built Fort Armstrong on the island for defensive reasons in 1816, Saukenuk was the birthplace of the Sauk war chief Black Hawk, for whom the Black Hawk War of 1831–1832 was named. Fort Armstrong served as the US militarys headquarters for the war, today the Black Hawk State Historic Site, listed on the National Register of Historic Places, includes much of the site of the original village of Saukenuk. The park includes a museum and a number of hiking trails along the Rock River, the Chicago, Rock Island & Pacific Railroad was founded here in 1851. It was informally known as the Rock Island Line, as part of later nineteenth-century development, two first-class hotels, the Harper House and the Rock Island House were built in town. Rock Island Arsenal has manufactured military equipment and ordnance for the U. S. Army since the 1880s, the railroad was liquidated in bankruptcy in 1980. The first railroad bridge across the Mississippi River was built between Arsenal Island and Davenport in 1856, two weeks after the bridge opened, the steamboat Effie Afton collided with the bridge, caught fire, and damaged the bridge. The owner of the Effie Afton sued the company for damages. This test case was appealed to the United States Supreme Court, although the original bridge is long gone, a monument exists on Arsenal Island marking the Illinois side

Dayton is the sixth-largest city in the U. S. state of Ohio and is the county seat of Montgomery County. A small portion of the city extends into Greene County, the Dayton-Springfield-Greenville Combined Statistical Area had a population of 1,080,044 in 2010, making it the 43rd-largest in the United States. Dayton is within Ohios Miami Valley region, just north of the Cincinnati–Northern Kentucky metropolitan area, Dayton also hosts significant research and development in fields like industrial, aeronautical, and astronautical engineering that have led to many technological innovations. Much of this innovation is due in part to Wright-Patterson Air Force Base, with the decline of heavy manufacturing, Daytons businesses have diversified into a service economy that includes insurance and legal sectors as well as healthcare and government sectors. Other than defense and aerospace, healthcare accounts for much of the Dayton areas economy, hospitals in the Greater Dayton area have an estimated combined employment of nearly 32,000 and a yearly economic impact of $6.8 billion. It is estimated that Premier Health Partners, a network, contributes more than $2 billion a year to the region through operating, employment. In 2011, Dayton was rated the No.3 city in the out of the top 50 cities in the United States by HealthGrades for excellence in health care. Many hospitals in the Dayton area are consistently ranked by Forbes, U. S. News & World Report, and HealthGrades for clinical excellence. Dayton is also noted for its association with aviation, the city is home to the National Museum of the United States Air Force and is the birthplace of Orville Wright, other well-known individuals born in the city include poet Paul Laurence Dunbar and entrepreneur John H. Patterson. Dayton is also known for its patents, inventions, and inventors that have come from the area. In 2008,2009, and 2010, Site Selection magazine ranked Dayton the No.1 mid-sized metropolitan area in the nation for economic development, also in 2010, Dayton was named one of the best places in the United States for college graduates to find a job. Dayton was founded on April 1,1796, by 12 settlers known as The Thompson Party and they traveled in March from Cincinnati up the Great Miami River by pirogue and landed at what is now St. Clair Street, where they found two small camps of Native Americans. Among them was Benjamin Van Cleve, whose memoirs provide insights into the Ohio Valleys history, two other groups traveling overland arrived several days later. In 1797, Daniel C. Cooper laid out Mad River Road, Ohio was admitted into the Union in 1803, and the city of Dayton was incorporated in 1805. The city was named after Jonathan Dayton, a captain in the American Revolutionary War who signed the U. S, constitution and owned a significant amount of land in the area. Historically, Dayton has been the home for many patents and inventions since the 1870s, according to the National Park Service, citing information from the U. S. Patent Office, Dayton had granted more patents per capita than any other U. S. city in 1890, the Wright brothers, inventors of the airplane, and Charles F. Kettering, world-renowned for his numerous inventions, hailed from Dayton. Paul Laurence Dunbar – a famous African-American poet and novelist – penned his most famous works in the late 19th century, innovation led to business growth in the region

Liberty L-12
–
The Liberty L-12 was an American 27-litre water-cooled 45° V-12 aircraft engine of 400 hp designed for a high power-to-weight ratio and ease of mass production. It was succeeded by the Packard 1A-2500, the two left their positions at the Fageol Motors Co. putting an end to the short production of the most luxurious automobile of the period. They were given the task of designing as rapidly as possible an aircraft engine that would rival if not surpass those of Great Britain, France, the Board specified that the engine would have a high power-to-weight ratio and be adaptable to mass production. The Board brought Vincent and Hall together on 29 May 1917 at the Willard Hotel in Washington, in July 1917, an eight-cylinder prototype assembled by Packards Detroit plant arrived in Washington for testing, and in August, the 12-cylinder version was tested and approved. Hall-Scott in California was considered too small to receive a production order, manufacturing by multiple factories was facilitated by its modular design. Lincoln constructed a new plant in record time, devoted entirely to Liberty engine production, by the time of the Armistice with Germany, the various companies had produced 13,574 Liberty engines, attaining a production rate of 150 engines per day. Production continued after the war, for a total of 20,478 engines built between July 4,1917 and 1919, although it is widely reported otherwise, a few Liberty engines did see action in France as power for the American version of the Airco DH.4. This led to Henry Leland leaving Cadillac to form the Lincoln Motor Company to make Liberty engines and he quickly gained a $10,000,000 government contract to build 6,000 engines. Subsequently the order was increased to 9,000 units, with the option to produce 8,000 more if the government needed them, more than 16,000 Liberty engines were produced during the calendar year 1918. To November 11,1918, more than 14,000 Liberty engines were produced, Lincoln had delivered 6,500 of the 400 hp, V-12, overhead camshaft engines when production ceased in January 1919. Durant later changed his mind and both Cadillac and Buick produced the engines, the Liberty engine was a modular design where four or six cylinders could be used in one or two banks, with the cylinders designed as individual units, each with their own water jacket. A pair of the 52 engines produced were destroyed by William Christmas testing his so-called Christmas Bullet fighter, an inverted Liberty 12-A referred to as the V-1650 was produced up to 1926 by Packard. The same designation was applied to the Packard V-1650 Merlin. This was a World War II Packard produced version of the Rolls-Royce Merlin, the Allison VG-1410 was an air-cooled inverted Liberty L-12, with a geared super-charger and Allison epicyclic propeller reduction gear and reduced displacement. An 8-cylinder V engine using Liberty cylinders in banks of four at 90°, the Nuffield Liberty tank engine was licensed and produced in World War II by the UK car manufacturer Nuffield. It was used in early Cruiser tanks, the Crusader, the Cavalier, the Nuffield Liberty ran through multiple versions, Mark I, US built engines modified in Britain. Modification incorporated new carburettors and a new system from Solex, revision of the crankcase breather, new timing gear. This produced 340 hp when governed to 1,500 rpm with the new carburettors, the air compressor wasnt used, and was removed on later engines Mark III, IIIA and IIIB, made for the Crusader tank

Seattle
–
Seattle is a seaport city on the west coast of the United States and the seat of King County, Washington. With an estimated 684,451 residents as of 2015, Seattle is the largest city in both the state of Washington and the Pacific Northwest region of North America. In July 2013, it was the major city in the United States. The city is situated on an isthmus between Puget Sound and Lake Washington, about 100 miles south of the Canada–United States border, a major gateway for trade with Asia, Seattle is the fourth-largest port in North America in terms of container handling as of 2015. The Seattle area was inhabited by Native Americans for at least 4,000 years before the first permanent European settlers. Arthur A. Denny and his group of travelers, subsequently known as the Denny Party, arrived from Illinois via Portland, the settlement was moved to the eastern shore of Elliott Bay and named Seattle in 1852, after Chief Siahl of the local Duwamish and Suquamish tribes. Logging was Seattles first major industry, but by the late-19th century, growth after World War II was partially due to the local Boeing company, which established Seattle as a center for aircraft manufacturing. The Seattle area developed as a technology center beginning in the 1980s, in 1994, Internet retailer Amazon was founded in Seattle. The stream of new software, biotechnology, and Internet companies led to an economic revival, Seattle has a noteworthy musical history. From 1918 to 1951, nearly two dozen jazz nightclubs existed along Jackson Street, from the current Chinatown/International District, to the Central District, the jazz scene developed the early careers of Ray Charles, Quincy Jones, Ernestine Anderson, and others. Seattle is also the birthplace of rock musician Jimi Hendrix and the alternative rock subgenre grunge, archaeological excavations suggest that Native Americans have inhabited the Seattle area for at least 4,000 years. By the time the first European settlers arrived, the people occupied at least seventeen villages in the areas around Elliott Bay, the first European to visit the Seattle area was George Vancouver, in May 1792 during his 1791–95 expedition to chart the Pacific Northwest. In 1851, a party led by Luther Collins made a location on land at the mouth of the Duwamish River. Thirteen days later, members of the Collins Party on the way to their claim passed three scouts of the Denny Party, members of the Denny Party claimed land on Alki Point on September 28,1851. The rest of the Denny Party set sail from Portland, Oregon, after a difficult winter, most of the Denny Party relocated across Elliott Bay and claimed land a second time at the site of present-day Pioneer Square, naming this new settlement Duwamps. For the next few years, New York Alki and Duwamps competed for dominance, david Swinson Doc Maynard, one of the founders of Duwamps, was the primary advocate to name the settlement after Chief Sealth of the Duwamish and Suquamish tribes. The name Seattle appears on official Washington Territory papers dated May 23,1853, in 1855, nominal land settlements were established. On January 14,1865, the Legislature of Territorial Washington incorporated the Town of Seattle with a board of managing the city

Airplane
–
An airplane or aeroplane is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller. Airplanes come in a variety of sizes, shapes, and wing configurations, the broad spectrum of uses for airplanes includes recreation, transportation of goods and people, military, and research. Commercial aviation is a massive industry involving the flying of tens of thousands of daily on airliners. Most airplanes are flown by a pilot on board the aircraft, the Wright brothers invented and flew the first airplane in 1903, recognized as the first sustained and controlled heavier-than-air powered flight. They built on the works of George Cayley dating from 1799, between 1867 and 1896, the German pioneer of human aviation Otto Lilienthal also studied heavier-than-air flight. Following its limited use in World War I, aircraft continued to develop. Airplanes had a presence in all the battles of World War II. The first jet aircraft was the German Heinkel He 178 in 1939, the first jet airliner, the de Havilland Comet, was introduced in 1952. The Boeing 707, the first widely successful commercial jet, was in service for more than 50 years. Aéroplane originally referred just to the wing, as it is a plane moving through the air, in an example of synecdoche, the word for the wing came to refer to the entire aircraft. In the United States and Canada, the airplane is used for powered fixed-wing aircraft. In the United Kingdom and most of the Commonwealth, the aeroplane is usually applied to these aircraft. Many stories from antiquity involve flight, such as the Greek legend of Icarus and Daedalus, and this machine may have been suspended for its flight. Some of the earliest recorded attempts with gliders were those by the 9th-century poet Abbas ibn Firnas, leonardo da Vinci researched the wing design of birds and designed a man-powered aircraft in his Codex on the Flight of Birds. In 1799, George Cayley set forth the concept of the airplane as a fixed-wing flying machine with separate systems for lift, propulsion. Cayley was building and flying models of fixed-wing aircraft as early as 1803, in 1856, Frenchman Jean-Marie Le Bris made the first powered flight, by having his glider LAlbatros artificiel pulled by a horse on a beach. Then Alexander F. Mozhaisky also made some innovative designs, in 1883, the American John J. Montgomery made a controlled flight in a glider. Other aviators who made similar flights at that time were Otto Lilienthal, Percy Pilcher, sir Hiram Maxim built a craft that weighed 3.5 tons, with a 110-foot wingspan that was powered by two 360-horsepower steam engines driving two propellers
