On the 16th of July, 1910 John Robertson Duigan completed the first flight of the Duigan pusher biplane, the first aircraft designed and built in Australia.
The first flight travelled only seven metres, but within two months they’d extended the journey to ninety metres.
Within a year, they were able to travel a kilometre at an altitude of thirty metres.
The brothers honoured on a 1970 postage stamp.
The Duigan brothers, John and Reginald built the aircraft almost entirely by themselves.
