The Boeing 757 is a twin-engine short-to-medium-range jetliner incorporating advanced technology for exceptional fuel efficiency, low noise levels, increased passenger comfort and top operating performance. The 757 offers other virtues as well, including great versatility by reducing airport congestion. It can fly both long- and short-range routes and its broad use effectively lends itself to "hub-and-spoke" planning. The 757 is one of seven commercial models that have sold more than 1,000 airplanes, and more than 1,030 757s are still in service.
