Inspection hole cover from the De Havilland Gipsy moth Aeroplane, by De Havilland Aircraft Company, Brent, Greater London, United Kingdom, 1928

In 1930, English aviator Amy Johnson (1903-1941) piloted Jason I to become the first woman to fly solo from Great Britain to Australia, flying from Croydon in Greater London, to Darwin in the Northern Territory. The Gipsy Moth contributed to the growth of private and sport flying between the two world wars, and was used for many great aviation feats. About 1000 were built by the de Havilland company at Edgware, Greater London.
