From Wikipedia:
The 727 is an American mid-size, narrow-body, three-engine, T-tailed commercial jet airliner. The first 727 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. The 727`s sales record for the most jet airliners ever sold was broken in the early 1990s by its younger stablemate, the 737.

The 727 was produced following the success of the 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 81 727-100 aircraft and 419 727-200 aircraft in airline service.

The 727 was designed to be used at smaller, regional airports, so independence from ground facilities was an important requirement. This gave rise to one of the 727`s most distinctive features: the built-in airstair that opens from the rear underbelly of the fuselage.

The Justice Prisoner and Alien Transportation System, also known as Con Air, currently uses four 727 aircraft to transport persons in legal custody between prisons, detaining centers, courthouses, and other places where they must be transported.
