American Airlines was the first US major carrier to order the MD-80 when it leased twenty 142-seat aircraft from McDonnell Douglas in October 1982 to replace its Boeing 727-100s. It committed to 67 firm orders plus 100 options in March 1984, and in 2002 its fleet peaked at more than 360 aircraft, 30% of the 1,191 produced.
The Pratt & Whitney JT8D is a low-bypass (0.96 to 1) turbofan engine introduced by Pratt & Whitney in February 1963 with the inaugural flight of the Boeing 727.It was a modification of the Pratt & Whitney J52 turbojet engine which powered the US Navy A-6 Intruder and A-4 Skyhawk attack aircraft.
In August 2013, USA Jet Airlines became the world's first operator of an MD-80 Passenger-to-Freighter conversion. The aircraft, converted by Aeronautical Engineers, Inc., competes against the Boeing 727 in the cargo market. [5] In February 2023, USA Jet retired the last three of their McDonnell Douglas DC-9 fleet. [citation needed]
For instance, waiting to swap out the 727 fleet it had at deregulation (yet the abortive 1982/1983 Braniff deal would have doubled-down on 727s), which were too large and too fuel inefficient (given the rise in fuel prices, which PSA also blamed) and too labor intensive (given its three person cockpit vs two places for the MD-80).
The 727 is equipped with a retractable tailskid that is designed to protect the aircraft in the event of an over-rotation on takeoff. The 727's fuselage has an outer diameter of 148 inches (3.8 m). This allows six-abreast seating (three per side) and a single aisle when 18-inch (46 cm) wide coach-class seats are installed.
The MD-80 series was further developed into the third generation, the MD-90 series, in the early 1990s. It has yet another fuselage stretch, an electronic flight instrument system (first introduced on the MD-88), and completely new International Aero V2500 high-bypass turbofan engines. In comparison to the very successful MD-80, relatively few ...
On December 3, 1990, two Northwest Airlines jetliners collided at Detroit Metropolitan Wayne County Airport. Flight 1482, a scheduled Douglas DC-9-14 operating from Detroit to Pittsburgh International Airport, taxied by mistake onto an active runway in dense fog and was hit by a departing Boeing 727 operating as Flight 299 to Memphis International Airport.
During the 2012 Boeing 727 crash experiment, a flight crew took off in the Boeing 727 that was to be crashed and flew it to a pre-selected desert site before safely parachuting from the airstair, as the Mexican government required that the plane be flown by a human crew for part of the experiment, especially as the aircraft's route to the crash ...
