The Hawker Siddeley Trident was a British short-haul airliner developed in the 1960s. It was notable for being one of the first commercial jets to feature a three-engine configuration, which provided improved performance and efficiency. The aircraft was designed to operate from shorter runways, making it suitable for regional airports. First flown in 1962, the Trident entered service with several airlines, including British Overseas Airways Corporation (BOAC). It was known for its quiet operation and advanced technology for its time, such as a fully automated landing system. The Trident remained in service until the late 1990s, with over 100 units produced.
