The rival Boeing 727 had quickly established a lead over the Trident. [32] The 727's early lead only strengthened it in subsequent competitions; one such example is Trans Australia Airlines, which had determined the Trident to be superior to the Boeing 727 from an operational standpoint, but it was also viewed as having been commercially risky ...
Boeing 727 cockpit Flight engineer's station on a Boeing 727-200F In 1959, Lord Douglas , chairman of British European Airways (BEA), suggested that Boeing and de Havilland Aircraft Company (later Hawker Siddeley ) work together on their trijet designs, the 727 and D.H.121 Trident , respectively.

Although it was designed in response to a specification issued by British European Airways (BEA), the Type 200 was larger than the airline's requirements and was closer to the Boeing 727 in size and range. The project was cancelled when BEA selected the Hawker Siddeley Trident instead. The Trident went on to have a production run of 117, while ...
The DH.121 design was modified to be smaller to fit the needs of one airline—British European Airways. Other airlines found it unattractive and turned to a rival tri-jet, the Boeing 727 which was much the same size as the initial DH.121 design. De Havilland, as Hawker Siddeley, built only 117 Tridents, while Boeing went on to sell over 1,800 ...
The most common configuration is having the central engine located in the rear fuselage and supplied with air by an S-shaped duct; this is used on the Hawker Siddeley Trident, Boeing 727, Tupolev Tu-154, Lockheed L-1011 TriStar, and, more recently, the Dassault Falcon 7X. The S-duct has low drag, and since the third engine is mounted closer to ...
Boeing 747-300 Trijet – downsized 747 to compete with the DC-10 and L-1011, changed to four engines; Blended Wing Body Trijet – proposed design based on the Boeing X-48; McDonnell Douglas MD-XX – stretched derivative of the DC-10, project shelved; North American NR-349 – proposed interceptor derivative of the A-5 Vigilante, cancelled
The 1960s jet airliners include the BAC One-Eleven and Douglas DC-9 twinjets; Boeing 727, Hawker Siddeley Trident and Tupolev Tu-154 trijets; and the paired multi-engined Ilyushin Il-62, and Vickers VC10. [4] The world-renowned supersonic Concorde first flew in 1969 but proved to be an economical disaster. Only 14 ever entered service, and the ...
The BAC Two-Eleven and BAC Three-Eleven were a pair of proposals for British airliners that were produced by the British Aircraft Corporation (BAC) during the late 1960s. The projects had emerged from design studies which had been aimed at competing first with the Boeing 727-200 and then with the proposed European Airbus.
