Bristol Racing Biplane

The Bristol Racing Biplane, also known as the Racer or Biplane No. 33 from its Bristol sequence number, was a British single seat biplane designed to combine the performance of a monoplane with the strength of a biplane. Robert Grandseigne and Leon Versepuy designed it, supervised by George Challenger, for the British and Colonial Aeroplane Company of Bristol. It was powered by a 50 hp Gnome engine driving a four bladed tractor propeller and had unequal span wings, each with a single steel tube spar, and a twin skid undercarriage whose long skids acted as brakes. Displayed at Olympia in 1911, it was taken to Larkhill in April 1911, where it overturned and was wrecked attempting its first flight.
