The first prototype aircraft – G-ALBO – flew on 16 August 1952. A second prototype aircraft G-ALRX was lost in an accident on December 1953. Engine intake icing problems delayed the Britannia 102’s entry into service. The 200-series aircraft built by Bristol was designed to provide cargo-carrying, or a combination of freight and passenger-carrying capabilities. Twenty-three Britannia aircraft were built for the Royal Air Force, providing troop and cargo transport. The later 300-series were built for transatlantic operation, and entered service by BOAC on the London-New York route on 19 December 1957.
By the time development was completed, “pure” jet airliners from France (Caravelle), United Kingdom (Comet) and the United States (Douglas DC-8 and Boeing 707) were about to enter service, and consequently, only 85 Britannias were built before production ended in 1960.
The RAF used twenty-three as long range troop and freight transports. Despite initial setbacks, Bristol’s ‘Whispering Giant’ proved itself a successful airliner with its speed, comfort and lack of vibration putting it ahead of its competitors.
