Bristol Brabazon

The Bristol Brabazon airliner was a gian of an aircraft larger even than a Boeing 747. It was also in many ways a strikingly advanced design for its day. Yet, commercially, this huge piston-engine airliner was a total failure for the British aircraft industry. The aircraft was named after Lord Brabazon of Tara, who headed a committee that produced a government report on British aviation that, among other things, called for construction of a large, high-speed airliner capable of crossing the Atlantic non-stop. Work on the project began in 1943, but the sheer size of the aircraft imposed problems that took time to resolve, delaying its maiden flight until September 1949. Technologically sophisticated, the eight-engine airliner pioneered innovations such as all-powered flying controls and high-pressure hydraulics.Planned facilities included a cocktail lounge and a cinema, yet despite its vast interior, the Bristol Brabazon was intended to carry only 60-80 passengers.
Airlines doubted they could operate such a large, heavy, expensive airliner at a profit with so few passengers. Only the prototype was ever built. With no one queuing up to buy the flying Goliath, it became a political embarrassment and was ignominiously scrapped in October 1953.
