The Dunne D.1, was an experimental tailless aircraft built in the UK in 1907. It comprised a main unit which could be flown as a glider, to which a chassis unit with power train could be added. The glider achieved a short flight in 1907. The D.1 was later rebuilt as the powered D.4, which achieved short hops in 1908.
