Avro 504K (H5199) [@ Shuttleworth Collection]
The Avro 504, which first flew at Brooklands in July 1913, was a straightforward development of the Type E, which was already on order for the Royal Flying Corps. In a production life spanning well over a decade more than 10,000 Avro 504s were built, serving as bomber, reconnaissance, fighter and training aircraft during World War I. It is as a trainer that the Avro 504 is best remembered; thousands of British and Commonwealth pilots learned to fly in it, and after the war surplus 504s were snapped up for “commercial use”, being used for joy-riding, ‘barnstorming’ and for training civilian pilots.
