The Trident, model DH121 or HS121, was a short/medium-range airliner designed by de Havilland in the 1950s, and built by the Hawker-Siddeley Group in the 1960s when de Havilland was merged, along with several other British aviation firms. Designed specifically to a British European Airways requirement, it had limited appeal to other airlines and sold only in small numbers. Nevertheless it was an important airliner in Europe but high operational costs doomed it to a short lifespan. British Airways chose to upgrade their fleet with the Boeing 737, and the Trident left service in the 1980s.
