In 1919,
John Kenworthy, chief designer of the motor manufacturer
Austin Motor Company, (who had built large numbers of aircraft under license during the First World War) designed a small single-seater light aircraft in order to cash in on an expected boom in private flying. The resulting aircraft, named the
Austin Whippet, was a small single-seat
biplane of mixed construction, with a fabric covered steel tube fuselage, and single-bay, folding wooden wings. The wings avoided the need for rigging wires by use of streamlined steel lift struts. The first prototype, powered by a two-cylinder horizontally opposed engine, flew in 1919, receiving its
Airworthiness Certificate in December that year. ==Operational history==
