VAUGHAN glider No.I 1909
This was a Chanute type two bay biplane with fixed boxkite type tail, the pilot standing in the lower center section and controlling the machine by weight shift. During the trials the top, and then the whole of the tail, were removed with disastrous results, convincing Vaughan of the need for proper control surfaces. He described a revised version in January 1911.

VAUGHAN glider No.II 1910-1912
After his experiences with No.I, Vaughan decided to build a Wright type glider with control surfaces and span increased to 33ft. This had a biplane elevator in front and a single rudder on tail booms. In the summer of 1912, Vaughan presented it to the Polytechnic Flying Society. It flew very successfully with this society at its gliding camps at Amberley on the slopes of the South Downs.
