Overview
The Hawker Siddeley HS-121 Trident is a British airliner produced by Hawker Siddeley.
In 1957, de Havilland proposed its DH.121 trijet design to a British European Airways (BEA) request.
By 1960, de Havilland had been acquired by Hawker Siddeley.
The Trident's maiden flight happened on 9 January 1962, and it was introduced on 1 April 1964, two months after its main competitor, the Boeing 727.
By the end of the programme in 1978, 117 Tridents had been produced. The Trident was withdrawn from service in 1995.
