Bristol Biplane Type 'T'

The Bristol Biplane Type 'T', sometimes called the Challenger-Dickson Biplane, was a derivative of the Bristol Boxkite built in 1911 by the British and Colonial Aeroplane Company as a cross country racing aircraft for Maurice Tabuteau. George Challenger designed it, with practical advice from the pilot Captain Bertram Dickson. It kept the Farman configuration of the Boxkite but added an enclosed nacelle for the pilot. The first aircraft was built for the 1911 Circuit de l'Europe race, powered by a 70 hp Gnome Gamma rotary engine, and Tabuteau completed all nine stages. Four more were built for the 1911 Daily Mail Circuit of Britain, and none finished that race.
