Dehavilland Giant Moth

The de Havilland DH.61 Giant Moth was a 1920s British large single-engined biplane transport built by de Havilland at Stag Lane Aerodrome, Edgware. Intended primarily for use in Australia, a number were also shipped to Canada. A total of 10 aircraft were built, including one in Canada built from components with the rest coming from the Stag Lane production line. Three aircraft for Canada (G-CAPG), (G-CARD) and (G-CAJT) were fitted with Short Brothers floats at Rochester before one was delivered to Canadian Vickers. This aircraft (G-CAJT) was sent to Western Canada Airlines Ltd. on a rental arrangement. During a proving flight on 23 October 1928, the Giant Moth suffered structural damage in the air and crashed at Calgary, Alberta in a non-fatal accident.[2] The other DH.61s continued to fly in Ontario in fire-fighting operations. One Giant Moth (CF-OAK) was modified from parts and flew with a Pratt & Witney Hornet engine.[3]

Three aircraft were used in Australia on air mail services by Australian Aerial Services Ltd and QANTAS. The two QANTAS Giant Moths, Apollo (G-AUJB) and Diana (G-AUJC), were acquired in April [4] and May 1929respectively.[5] They were the first QANTAS aircraft equipped with toilets.[6] The airline took them out of service in 1935 because the Bristol Jupiter XI engines were unreliable.[6] Apollo was sold that year and crashed near Mubo, New Guinea, on 9 May 1938.[4]
