Military derivatives include the E-767 for surveillance and the KC-767 and KC-46 aerial tankers.Īfter being initially used on U.S. Studies for a higher-capacity 767 in 1986 led Boeing to develop the larger 777 twinjet, introduced in June 1995. Its two-crew glass cockpit, a first for a Boeing airliner, was developed jointly for the 757 − a narrow-body aircraft, allowing a common pilot type rating. The aircraft has a conventional tail and a supercritical wing for reduced aerodynamic drag. JT9D engines were eventually replaced by PW4000 engines. The 767 is Boeing's first wide-body twinjet, powered by General Electric CF6, Rolls-Royce RB211, or Pratt & Whitney JT9D turbofans. To complement the larger 747, it has a seven-abreast cross-section, accommodating smaller LD2 ULD cargo containers. It was stretched again into the 767-400ER from September 2000. The 767-300F, a production freighter version, debuted in October 1995. It was stretched into the 767-300 in October 1986, followed by the 767-300ER in 1988, the most popular variant. The original 767-200 entered service on September 8, 1982, with United Airlines, and the extended-range 767-200ER in 1984. The aircraft was launched as the 7X7 program on July 14, 1978, the prototype first flew on September 26, 1981, and it was certified on July 30, 1982. The Boeing 767 is an American wide-body aircraft developed and manufactured by Boeing Commercial Airplanes.
