The Boeing 757 is a short to medium range narrow-body commercial passenger aircraft manufactured by Boeing Commercial Airplanes. It was launched by Eastern Air Lines and British Airways to replace the Boeing 727 and entered service in 1983. Production of the 757 ended on October 28, 2004 after 1,050 had been built.[1] The final aircraft was delivered to Shanghai Airlines on November 28, 2005. As of July 2007, a total of 1,019 Boeing 757 aircraft were in airline service.

Design and development

The 757 (designated “7N7″ during initial development)[3] was designed by Boeing to replace the Boeing 727 and complement the Boeing 767 on thin routes. Boeing originally offered the airlines a stretched, re-engined 727-200, known as the 727-300, but this never received enough interest from the airlines to proceed. Early 7N7 and 757 concepts featured a “T-tail” with under-wing engines, but a conventional tail was ultimately adopted. The 757 retains the same upper-fuselage diameter as the previous Boeing 707, 727, and 737. The first Boeing 757 was delivered to Eastern Air Lines on 22 December 1982.

The 757 was the first Boeing airliner launched with engines produced outside the United States, with early customers selecting the Rolls-Royce RB211. Pratt & Whitney soon offered the PW2000, launched by Delta Air Lines. General Electric offered an engine option early in the program, the CF6-32, but eventually abandoned the engine due to insufficient demand.
