Boeing 707 narrow-body airliner (1957)

The Boeing 707 is an American long-range narrow-body airliner produced by Boeing Commercial Airplanes, its first jetliner. Developed from the Boeing 367-80, a prototype first flown in 1954, the initial 707-120 first flew on December 20, 1957. Pan American World Airways began regular 707 service on October 26, 1958, and it was built until 1979. A quadjet, the 707 has a swept wing with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later 720, 727, 737, and 757.

Although it was not the first commercial jetliner in service, the 707 was the first to be widespread and is often credited with beginning the Jet Age.[5] It dominated passenger air transport in the 1960s and remained common through the 1970s, on domestic, transcontinental, and transatlantic flights, as well as cargo and military applications. It established Boeing as a dominant airliner manufacturer with its 7×7 series. The initial, 145-foot-long (44 m) 707-120 was powered by Pratt & Whitney JT3C turbojet engines. The shortened long-range 707-138 and the more powerful 707-220 entered service in 1959

Operational History

During and after World War II, Boeing was known for its military aircraft. The company had produced innovative and important bombers, from the B-17 Flying Fortress and B-29 Superfortress, to the jet-powered B-47 Stratojet and B-52 Stratofortress. The company had produced aircraft that were not as successful commercially as those from Douglas and other competitors, with the only noteworthy exception being the Boeing 314 Clipper. As Douglas and Lockheed dominated the postwar air transport boom the demand for Boeing’s offering, the 377 Stratocruiser, quickly faded with only 56 examples sold and no new orders as the 1940s drew to a close. That venture had netted the company a $15 million loss.[6] During 1949 and 1950, Boeing embarked on studies for a new jet transport and saw advantages with a design aimed at both military and civilian markets. Aerial refueling was becoming a standard technique for military aircraft, with over 800 KC-97 Stratofreighters on order. The KC-97 was not ideally suited for operations with the USAF’s new fleet of jet-powered bombers; this was where Boeing’s new design would win military orders.

The VC-137C variant of the Stratoliner was a special-purpose design meant to serve as Air Force One, the secure transport for the President of the United States. These models were in operational use from 1962 to 1990. The two aircraft remain on display: SAM 26000 is at the National Museum of the United States Air Force near Dayton, Ohio and SAM 27000 is at the Ronald Reagan Presidential Library in Simi Valley, California.

The Canadian Forces also operated the Boeing 707 with the designation CC-137 Husky (707-347C) from 1971 to 1997.

The 132 in (3,352.80 mm) wide fuselage of the Dash 80 was large enough for four-abreast (two-plus-two) seating like the Stratocruiser. Answering customers' demands and under Douglas competition, Boeing soon realized this would not provide a viable payload, so it widened the fuselage to 144 in (3,660 mm) to allow five-abreast seating and use of the KC-135's tooling.[10] Douglas Aircraft had launched its DC-8 with a fuselage width of 147 in (3,730 mm). The airlines liked the extra space and six-abreast seating, so Boeing increased the 707's width again to compete, this time to 148 in (3,760 mm).
