The Boeing 727 is a mid-size, narrow-body, three-engine, T-tailed commercial jet airliner, manufactured by Boeing. The Boeing 727 first flew in 1963, and, for over a decade, it was the most produced commercial jet airliner in the world. When production ended in 1984, a total of 1,831 aircraft had been produced.[2] The 727's sales record for the most jet airliners ever sold was broken in the early 1990s by its younger stablemate, the Boeing 737.

The 727 was produced following the success of the Boeing 707 quad-jet airliner. Designed for short-haul routes, the 727 became a mainstay of airlines' domestic route networks. A stretched variant, the 727-200, debuted in 1967. In August 2008, there were a total of 81 Boeing 727-100 aircraft and 419 727-200 aircraft in airline service.[3]

Design and development

The 727 design arose as a compromise between United Airlines, American Airlines, and Eastern Air Lines requirements over the configuration of a jet airliner to service smaller cities, which often had shorter runways and smaller passenger demand.[4] United Airlines wanted a four-engined aircraft for its flights to high-altitude airports, especially its hub at Stapleton International Airport at Denver, Colorado.[4] American, which was operating the four-engined Boeing 707 and Boeing 720, wanted a twin-engined aircraft for efficiency reasons. Eastern wanted a third engine for its overwater flights to the Caribbean, since at that time twin-engined commercial flights were limited by regulations to routes with 60-minute maximum flying time to an airport (see ETOPS/LROPS). Eventually, the airlines agreed on a trijet, and thus the 727 was born.[4]
