Conisborough Glider No. 1
The Conisborough Glider No. J was flown by the Conisborough and District Aero Society, Yorks., during 1911. It was a biplane of 42 ft. span, presented to the Society by the Sheffield Aero Club. In this form it carried its pilot to a height of 20 ft. when towed by hand into a light breeze. This was evidently thought to be too risky, and the span was reduced later to 24 ft. for training purposes.
