The Boeing 707 is a mid-size, narrow-body four-engine jet airliner that was manufactured by Boeing Commercial Airplanes from 1958 to 1979. Its name is most commonly pronounced as "Seven Oh Seven". Versions of the aircraft have a capacity from 140 to 202 passengers and a range of 3,680 to 3,735 nautical miles (6,820 to 6,917 km). Developed as Boeing's first jet airliner, the 707 features a swept-wing design with podded engines. Dominating passenger air transport in the 1960s, and remaining common throughout the 1970s, the 707 is generally credited with ushering in the Jet Age. Although it was not the First jetliner in service, the 707 was the first to be commercially successful. It established Boeing as one of the largest manufacturers of passenger aircraft, and led to the later series of aircraft with "7×7" designations. The subsequent 727, 737 and 757 also share elements of the 707's fuselage design.

The 707 was developed from the 367-80, a prototype jet aircraft which Boeing produced as a design study in 1954. A larger fuselage cross-section and other design modifications resulted in the initial production 707-120, powered by Pratt & Whitney JT3C turbojet engines, which first flew on December 20, 1957. Pan American World Airways began regularly scheduled 707 service with the type's first commercial flight on October 26, 1958. Subsequent derivatives included the shortened long-range 707-138 and the stretched 707-320, both of which entered service in 1959. A smaller short-range variant, the 720, was introduced in 1960. The 707-420, a version of the stretched 707 with Rolls Royce Conway 508 turbofans,debuted in 1960, while Pratt & Whiteny JT3D turbofans debuted on the 707-120B and 707-320B models in 1961 and 1962, respectively.

During its service career, the 707 has been used in a variety of roles, including domestic, transcontiental, and transatlantic operations. The 707 has also been used for cargo and military applications. A convertible passenger-freighter model, the 707-320C, entered service in 1963, and passenger 707s have been modified to freighter configurations. Military derivatives include the E-3 Sentry airborne reconnaissance aircraft and the C-137 Stratoliner VIP transports. During the 707's production run, Boeing produced and delivered a total of 1,011 aircraft, including the smaller 720 series. Over 800 military versions were also produced. As of August 2011, 10 examples of the 707 remain in airline service

The 707-420 was identical to the -320 but fitted with Rolls Royce Conway 508 turbofans (or by-pass turbojets as they were known at the time). First announced customer was Lufthansa. BOAC's controversial order was announced six months later but the British carrier got the first service-ready aircraft off the production line. The British Air Registration Board refused to give the aircraft a certificate of airworthiness in the form presented, citing insufficient lateral control, excessive rudder forces and the ability to over rotate on take off, stalling the wing on the ground (a fault of the de Havilland Comet 1). Boeing responded by adding 40 inches to the vertical tail, applying full instead of partial rudder boost and fitting an underfin to prevent over rotation. These modifications became standard on all 707 variants and were retrofitted to all previously built aircraft. Only 37 -420s were built, for BOAC, Lufthansa, Air-India, El Al and Varig; Lufthansa was the first to carry passengers, in March 1960.
