Question: Who is the manufacturer of the 747 aircraft, with the name of the company whose downturn drastically affected Seattle's economy?

full_context: Document 1: Boeing 747: The Boeing 747 is an American wide - body commercial jet airliner and cargo aircraft, often referred to by its original nickname, ``Jumbo Jet ''. Its distinctive`` hump'' upper deck along the forward part of the aircraft makes it among the world's most recognizable aircraft, and it was the first wide - body produced. Manufactured by Boeing's Commercial Airplane unit in the United States, the original version of the 747 was envisioned to have 150 percent greater capacity than the Boeing 707, one of the common large commercial aircraft of the 1960s. First flown commercially in 1970, the 747 held the passenger capacity record for 37 years.
Document 2: Seattle: War work again brought local prosperity during World War II, this time centered on Boeing aircraft. The war dispersed the city's numerous Japanese-American businessmen due to the Japanese American internment. After the war, the local economy dipped. It rose again with Boeing's growing dominance in the commercial airliner market. Seattle celebrated its restored prosperity and made a bid for world recognition with the Century 21 Exposition, the 1962 World's Fair. Another major local economic downturn was in the late 1960s and early 1970s, at a time when Boeing was heavily affected by the oil crises, loss of Government contracts, and costs and delays associated with the Boeing 747. Many people left the area to look for work elsewhere, and two local real estate agents put up a billboard reading "Will the last person leaving Seattle – Turn out the lights."

Document 4: General Electric GEnx: The General Electric GEnx ("General Electric Next-generation") is an advanced dual rotor, axial flow, high-bypass turbofan jet engine in production by GE Aviation for the Boeing 787 and 747-8. The GEnx is intended to replace the CF6 in GE's product line.
Document 5: Seattle: Prior to moving its headquarters to Chicago, aerospace manufacturer Boeing (#30) was the largest company based in Seattle. Its largest division is still headquartered in nearby Renton, and the company has large aircraft manufacturing plants in Everett and Renton, so it remains the largest private employer in the Seattle metropolitan area. Former Seattle Mayor Greg Nickels announced a desire to spark a new economic boom driven by the biotechnology industry in 2006. Major redevelopment of the South Lake Union neighborhood is underway, in an effort to attract new and established biotech companies to the city, joining biotech companies Corixa (acquired by GlaxoSmithKline), Immunex (now part of Amgen), Trubion, and ZymoGenetics. Vulcan Inc., the holding company of billionaire Paul Allen, is behind most of the development projects in the region. While some see the new development as an economic boon, others have criticized Nickels and the Seattle City Council for pandering to Allen's interests at taxpayers' expense. Also in 2006, Expansion Magazine ranked Seattle among the top 10 metropolitan areas in the nation for climates favorable to business expansion. In 2005, Forbes ranked Seattle as the most expensive American city for buying a house based on the local income levels. In 2013, however, the magazine ranked Seattle No. 9 on its list of the Best Places for Business and Careers.
Document 6: Airbus A380: The Airbus A380 is a double - deck, wide - body, four - engine jet airliner manufactured by European manufacturer Airbus. It is the world's largest passenger airliner, and the airports at which it operates have upgraded facilities to accommodate it. It was initially named Airbus A3XX and designed to challenge Boeing's monopoly in the large - aircraft market. The A380 made its first flight on 27 April 2005 and entered commercial service on 25 October 2007 with Singapore Airlines. An improved version, the A380plus, is under development.
Document 7: Seattle: Logging was Seattle's first major industry, but by the late 19th century the city had become a commercial and shipbuilding center as a gateway to Alaska during the Klondike Gold Rush. By 1910, Seattle was one of the 25 largest cities in the country. However, the Great Depression severely damaged the city's economy. Growth returned during and after World War II, due partially 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, with companies like Microsoft becoming established in the region. In 1994 the Internet retail giant Amazon was founded in Seattle. The stream of new software, biotechnology, and Internet companies led to an economic revival, which increased the city's population by almost 50,000 between 1990 and 2000.

Document 9: Seattle: Seattle in this period attracted widespread attention as home to these many companies, but also by hosting the 1990 Goodwill Games and the APEC leaders conference in 1993, as well as through the worldwide popularity of grunge, a sound that had developed in Seattle's independent music scene. Another bid for worldwide attention—hosting the World Trade Organization Ministerial Conference of 1999—garnered visibility, but not in the way its sponsors desired, as related protest activity and police reactions to those protests overshadowed the conference itself. The city was further shaken by the Mardi Gras Riots in 2001, and then literally shaken the following day by the Nisqually earthquake.
Document 10: Seattle: A shipbuilding boom in the early part of the 20th century became massive during World War I, making Seattle somewhat of a company town; the subsequent retrenchment led to the Seattle General Strike of 1919, the first general strike in the country. A 1912 city development plan by Virgil Bogue went largely unused. Seattle was mildly prosperous in the 1920s but was particularly hard hit in the Great Depression, experiencing some of the country's harshest labor strife in that era. Violence during the Maritime Strike of 1934 cost Seattle much of its maritime traffic, which was rerouted to the Port of Los Angeles.
Document 11: Boeing 747-8: The Boeing 747-8 is a wide-body jet airliner developed by Boeing Commercial Airplanes. It was officially announced in 2005. The 747-8 is the third generation of the 747, with a lengthened fuselage, redesigned wings, new engines, and improved efficiency. The 747-8 is the largest 747 version, the largest commercial aircraft built in the United States, and the longest operational passenger aircraft in the world.
Document 12: Seattle: The second and most dramatic boom and bust resulted from the Klondike Gold Rush, which ended the depression that had begun with the Panic of 1893; in a short time, Seattle became a major transportation center. On July 14, 1897, the S.S. Portland docked with its famed "ton of gold", and Seattle became the main transport and supply point for the miners in Alaska and the Yukon. Few of those working men found lasting wealth, however; it was Seattle's business of clothing the miners and feeding them salmon that panned out in the long run. Along with Seattle, other cities like Everett, Tacoma, Port Townsend, Bremerton, and Olympia, all in the Puget Sound region, became competitors for exchange, rather than mother lodes for extraction, of precious metals. The boom lasted well into the early part of the 20th century and funded many new Seattle companies and products. In 1907, 19-year-old James E. Casey borrowed $100 from a friend and founded the American Messenger Company (later UPS). Other Seattle companies founded during this period include Nordstrom and Eddie Bauer. Seattle brought in the Olmsted Brothers landscape architecture firm to design a system of parks and boulevards.
Document 13: Boeing 747: The huge cost of developing the 747 and building the Everett factory meant that Boeing had to borrow heavily from a banking syndicate. During the final months before delivery of the first aircraft, the company had to repeatedly request additional funding to complete the project. Had this been refused, Boeing's survival would have been threatened. The firm's debt exceeded $2 billion, with the $1.2 billion owed to the banks setting a record for all companies. Allen later said, "It was really too large a project for us." Ultimately, the gamble succeeded, and Boeing held a monopoly in very large passenger aircraft production for many years.
Document 14: Seattle: Seattle's economy is driven by a mix of older industrial companies, and "new economy" Internet and technology companies, service, design and clean technology companies. The city's gross metropolitan product was $231 billion in 2010, making it the 11th largest metropolitan economy in the United States. The Port of Seattle, which also operates Seattle–Tacoma International Airport, is a major gateway for trade with Asia and cruises to Alaska, and is the 8th largest port in the United States in terms of container capacity. Though it was affected by the Great Recession, Seattle has retained a comparatively strong economy, and remains a hotbed for start-up businesses, especially in green building and clean technologies: it was ranked as America's No. 1 "smarter city" based on its government policies and green economy. In February 2010, the city government committed Seattle to becoming North America's first "climate neutral" city, with a goal of reaching zero net per capita greenhouse gas emissions by 2030.
Document 15: Douglas DC-8: The Douglas DC-8 (also known as the McDonnell Douglas DC-8) is an American four-engine mid- to long-range narrow-body jet airliner built from 1958 to 1972 by the Douglas Aircraft Company. Launched after the competing Boeing 707, the DC-8 nevertheless kept Douglas in a strong position in the airliner market, and remained in production until 1972 when it began to be superseded by larger wide-body designs, including the Boeing 747, McDonnell Douglas DC-10, and Lockheed L-1011 TriStar. The DC-8's design allowed it a slightly larger cargo capacity than the 707 and some re-engined DC-8s are still in use as freighters.
