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 airliner has a seating capacity of up to 400 passengers and a range of over 4,000 nautical miles (7,410 km; 4,600 mi). Its trijet configuration has three Rolls-Royce RB211 engines with one engine under each wing, along with a third engine center-mounted with an S-duct air inlet embedded in the tail and the upper fuselage .
For example, if the dimensions are all doubled in size, then the area and lifting capacity increase 2 × 2 = 4 times, while the volume increases 2 × 2 × 2 = 8 times. For a passenger aircraft, this doubling in size allows up to twice the cabin space per passenger.
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 wing of the passenger version holds 64,225 US gal (243 m 3) of jet fuel, and that of the cargo aircraft 60,925 US gal (231 m 3). [120] Compared to the 747-400 and an intermediate 747 Advanced concept, the extra fuel capacity in the redesigned wing allowed Boeing to avoid adding costly new tanks to the horizontal tail . [ 121 ]
