In response, design began on a new Trident 1A, powered with up-rated Rolls-Royce Spey 510 engines of 10,700 lbf (47.6 kN) thrust, and a larger wing with more fuel, raising gross weight to 120,000 lb (54,000 kg) and range to 1,800 mi (2,900 km), but AA eventually declined the aircraft in favour of the Boeing 727.
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.

The placement of the remaining two engines varies. Most smaller aircraft, such as the Hawker Siddeley Trident and the Boeing 727, as well as the intermediate-sized Tupolev Tu-154, have two side-mount engine pylons in a T-tail configuration. The larger widebody Lockheed TriStar and DC-10/MD-11 mount an engine underneath each wing.

Conceptually similar to the British Hawker Siddeley Trident, which first flew in 1962, and the American Boeing 727, which first flew in 1963, the medium-range Tu-154 was marketed by Tupolev at the same time as Ilyushin was marketing its long-range Ilyushin Il-62. The Soviet Ministry of Aircraft Industry chose the Tu-154, as it incorporated the ...
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 ...
This is a list of aircraft by date and usage. The date shown is the introduction of the first model of a line but not the current model. For instance, while "the most popular" aircraft, such as Boeing 737 and 747 were introduced in 1960x, their recent models were revealed in the 21st century. [1]
