Boeing 727

The Boeing 727 is a mid-size, narrow-body, three-engine commercial jet airliner. It first took to the skies in 1963 and for over a decade was the most produced commercial jet airliner in the world. 1,831 727s were delivered. The 727's sales record for the most jets bought in history was broken in the early 1990s by its sister, the Boeing 737. In August 2006, a total of 127 Boeing 727-100 aircraft and 493 Boeing 727-200 aircraft remain in airline service.
