Boeing 727

The Boeing 727 is a mid-size, narrow-body three-engine jet airliner built by Boeing Commercial Airplanes. It has a capacity of 149 to 189 passengers and a range of 2,400 to 2,700 nautical miles (4,400 to 5,000 km), depending on variant. Intended for short-haul routes, the 727 is capable of operating out of restricted length runways and smaller airports. Its trijet design features three Pratt & Whitney JT8D engines at the rear section of the aircraft, along with a T-tail. One engine each is mounted on either side of the rear fuselage, while a center-installed engine connects through an S-duct to an air inlet mounted at the junction of the tail and the upper fuselage.

The 727 followed the success of the 707 quad-jet airliner, with which it shares its upper fuselage cross-section and cockpit design. The original 727-100 completed its maiden flight in 1963 and entered service with Eastern Air Lines the following year. The stretched 727-200 first flew in 1967 and entered service with Northeast Airlines later that year. During its production run, the 727 became a mainstay of airlines' domestic route networks, and was also used on short- and medium-range international routes. Passenger, freighter, and convertible versions of the 727 were built. The last 727 was delivered in 1984
