[edit] History

Following the success of the de Havilland DH.50 in Australia the company was asked to design a larger replacement using a Bristol Jupiter engine. The cabin had room for up to 8 passengers with the pilot in an open cockpit behind the wings. The aircraft took only ten weeks to design and the prototype first flew in December 1927. Following test flights in England the aircraft was sent to De Havilland Aircraft pty in Melbourne, Australia. It first flew on 2 March 1928 in aviation and was used on scheduled services between Adelaide and Broken Hill by MacRobertson Miller Aviation. The prototype was originally called Canberra which was used as a type name until changed to Giant Moth.

Ten aircraft were built (including one in Canada built from components). Two aircraft for Canada were fitted with Short Brothers floats at Rochester before delivery to Western Canada Airlines Ltd. Three aircraft were used in Australia on air mail services by Australian Aerial Services Ltd and QANTAS. Another aircraft G-AAAN was bought by the Daily Mail to carry a photographer and his motorcycle around the United Kingdom, the aircraft would land at the nearest airfield to the story. This aircraft was also equipped with a dark room to enable the photographs to be developed on the return journey. One aircraft G-AAEV named Youth of Britain was used by Alan Cobham in an aviation promotional tour in 1929 of the United Kingdom. During the tour the aircraft carried 10,000 schoolchildren were given free trips.
