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%.
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.

After the 747 test flights, Boeing re-registered the aircraft as N1352B in July 1970 to explore missions beyond its original design specifications. These missions were primarily military, including using N1352B as a refuelling tanker for the Lockheed SR-71 Blackbird and the Boeing B-52 Stratofortress. Unfortunately, the idea of using the Boeing ...
The Pratt & Whitney JT9D high-bypass turbofan engine was developed for the Boeing 747. The JT9D program was launched in September 1965 and the first engine was tested in December 1966. It received its FAA certification in May 1969 and entered service in January 1970 on the Boeing 747.
The first flight with one of these engines took place on 22 February 2007, using a Boeing 747-100, fitted with one GEnx engine in the number 2 (inboard left hand side) position. By fall 2019, General Electric was offering the GEnx-2B, developed for the 747-8, for the revised 767-XF variant based on the 767-400ER, but needed enough volume to ...
The 747-8 is a development of the Boeing 747 that takes advantage of improvements in technology and aerodynamics. The two 747-8 variants feature a fuselage stretch of 18.3 ft (5.6 m) over the 747-400, bringing the total length to 250 ft 2 in (76.25 m).
A shorter derivative of the 747-100, the SP was developed to target two market requirements. [5] The first was a need to compete with the DC-10 and L-1011 while maintaining commonality with the 747, [5] which in its standard form was too large for many routes. Until the arrival of the 767, Boeing lacked a mid-sized wide-body to compete in this ...
