Delta Alpha was the first prototype Gipsy Major powered DH82A Tiger Moth and joined the de Havilland School of Flying in February 1933.

She then served with the RAF as BB724 before being disposed of in 1943 and purchased by a Devonshire landowner and put into storage until being purchased by Richard Biddle in 1977. Following a full restoration she was badly damaged hitting a pylon after only 20 minutes of flight in a forced landing during test flying, was then subsequently rebuilt again by the same owner only to suffer further considerable damage in a hangar fire.

In 1997 she was purchased by Bryn Hughes and in 2008 following a meticulous restoration took to the air once again at the hands of Dennis Neville who along with Scott Butler were both privileged to fly Delta Alpha.
