One-hundred, ten years ago, today…
The Duigan […] biplane was an early aircraft which made the first powered flight by an Australian-designed and built machine when it flew in Victoria in 1910. The aircraft was constructed by John Duigan, with help from his brother Reginald, on their family farm at Mia Mia. The effort was especially significant in that the brothers built the aircraft almost entirely by themselves and without input from the pioneering aviation community. [A] photo-postcard of the Wright Flyer inspired the design and Sir Hiram Maxim‘s book Artificial and Natural Flight provided the theoretical basis. The only components not built by the Duigans themselves were the engine, made by the J. E. Tilley Engineering Company of Melbourne and the propeller. However, both of these components were extensively modified by John before they could be used.
The aircraft flew for the first time on July 16, 1910, taking off under its own power and flying [24 feet] (7 meters). Within two months, this had been extended to [300 feet] (90 meters) and, soon thereafter, to [590 feet with an altitude of 12 feet] (180 meters [with] an altitude of 3.5 meters). By the end of the year, Duigan had made a flight of [nearly a mile] (1 km) at an altitude of [100 feet] (30 meters).
Duigan informed the Department of Defence of his achievements, hoping to claim a £5,000 prize that had been offered in September 1909 for the construction of an aircraft suitable for military purposes. Duigan was ineligible for the prize, which had expired at the end of March 1910 but, was asked to demonstrate his aircraft for the military anyway. He also flew it in a public demonstration in front of a crowd of 1,000 spectators at Bendigo Racecourse in January 1911. In 1920, Duigan donated the aircraft to the Industrial and Technological Museum of Victoria, which was later absorbed into Museum Victoria.
Museum Victoria also preserves a flying replica of the Duigan biplane built by Ronald Lewis and flown in 1990. It was donated to the museum in 2000.
