The Bristol Type 175 Britannia is a British aircraft designed in the 1950s, primarily for long-range passenger and cargo transport. It features a high-wing design and four Bristol Proteus turboprop engines, allowing it to operate efficiently over long distances. The Britannia was known for its spacious cabin and advanced technology for its time. First flown in 1952, the Britannia entered service with several airlines, including British Overseas Airways Corporation (BOAC). Despite its innovative design, it faced competition from jet aircraft, leading to a decline in its use by the late 1960s. The Britannia remains a notable example of post-war aviation engineering.
