The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the 707 in October 1958, Pan Am wanted a jet 2 + 1 ⁄ 2 times its size, to reduce its seat cost by 30%. In 1965, Joe Sutter left the 737 development program to design ...
The Boeing 747-400 is a large, long-range wide-body airliner produced by Boeing Commercial Airplanes, an advanced variant of the initial Boeing 747.The "Advanced Series 300" was announced at the September 1984 Farnborough Airshow, targeting a 10% cost reduction with more efficient engines and 1,000 nautical miles [nmi] (1,900 km; 1,200 mi) of additional range.
The 747-8 was the first lengthened 747 to go into production and the second 747 version with a fuselage of modified length after the shortened 747SP. The 747-8 was intended to use the same engine and cockpit technology as that of the 787, including the General Electric GEnx turbofan and fly-by-wire ailerons and spoilers. [9]
English: An overlay diagram showing five of the largest airplanes ever built, the Hughes H-4 Spruce Goose (airplane with the greatest height), the Antonov An-225 Mriya (the largest airplane), the Boeing 747-8 Intercontinental (the largest version of the Boeing 747 Jumbojet), the Airbus A380-800 (the largest passenger airplane), and the Scaled Composites Stratolaunch (airplane with the greatest ...
However, some of the engineering work on the 747SP was reused with the development of the 747-300. In the 747SP, the upper deck begins over the section of fuselage that contains the wing box, not ahead of the wing box (as is the case with the 747-100 and 747-200). This same design was used in the 747-300 and newer 747-400, resulting in a ...
A cross-section comparison of Airbus A380 (double-deck the full length) and Boeing 747-400 (double-deck only in the front section) The production of the large Boeing 747-8 and Airbus A380 four-engine, long-haul jets has come to an end as airlines are now preferring the smaller, more efficient Airbus A350, Boeing 787 and Boeing 777 twin-engine ...

Pratt & Whitney faced difficulties with the JT9D design during the Boeing 747 test program. Engine failures during the flight test program resulted in thirty aircraft being parked outside the factory with concrete blocks hanging from the pylons, awaiting redesigned engines. Boeing and Pratt & Whitney worked together in 1969 to solve the problem.
