The Boeing 707 is an American long-range narrow-body airliner that was developed and produced by Boeing Commercial Airplanes, its first jetliner. The initial 707-120 first flew on December 20, 1957. Pan American World Airways began regular 707 service on October 26, 1958. The airplane 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.
Powered by Pratt & Whitney JT4A turbojets, the 707-320 entered service in 1959, and the 707-420 with Rolls-Royce Conway turbofans in 1960.
The 707-320C convertible passenger-freighter model entered service in 1963, and passenger 707s have been converted to freighter configurations. Military
