The Bristol Type 167 Brabazon was a large propeller-driven airliner which was designed by the Bristol Aeroplane Company to fly transatlantic routes between the United Kingdom and the United States. The type was named Brabazon after the Brabazon Committee and its chairman, Lord Brabazon of Tara, who had developed the specification for which the airliner had been designed.
At the time of its construction, the Brabazon was amongst one of the largest aircraft in the world to have ever been built, being sized roughly between the much later Airbus A300 and Boeing 767airliners. Despite its vast size, the Brabazon was designed to carry a total of only 100 passengers, each one being allocated their own spacious area about the size of the entire interior of a small car. On 4 September 1949, the first prototype conducted its maiden flight. In addition to participating in a flight test programme in support to intended production aircraft, the prototype made high-profile public flying displays at the 1950 Farnborough Airshow, Heathrow Airport, and the 1951 Paris Air Show.
However, the Brabazon was unable to attract any firm commitments for the type due a widespread feeling amongst airlines that the airliner was too large and expensive to be practical and applicable to their existing operations. Being unable to attract any orders, the aircraft became regarded as a commercial failure. On 17 July 1953, Duncan Sandys, the Minister of Supply, announced that the Brabazon had been cancelled due to a lack of military or civil orders for the type. In the end, only the single prototype was flown; it was broken up in 1953 for scrap, along with the uncompleted turboprop-powered Brabazon I Mk.II.
