The Boeing 707 is a mid-size, narrow-body four-engine jet airliner built by Boeing Commercial Airplanes from 1958 to 1979. Its name is commonly pronounced as "Seven Oh Seven". Versions of the aircraft have a capacity from 140 to 189 passengers and a range of 2,500 to 5,750 nautical miles (4,600 to 10,650 km).
Developed as Boeing's first jet airliner, the 707 is a swept-wing design with podded engines. Dominating passenger air transport in the 1960s and remaining common through 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 "7x7" designations. The later 727, 737, and 757 share elements of the 707's fuselage design.
The 707 was developed from the Boeing 367-80, a prototype jet aircraft first flown 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 regular 707 service on October 26, 1958. Later 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 & Whitney JT3D turbofans debuted on the 707-120B and 707-320B models in 1961 and 1962, respectively.
The 707 has been used on domestic, transcontinental and transatlantic flights, and 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 Boeing 707 were in airline service.
