Design and development

At the end of 1937 Sproule and Ivanoff decided to design a glider that would be cheap, be easy to control and have a good speed range. It would also have wing-folding for quick assembly.[1] The glider was a high wing strut-supported single-spar monoplane with no flaps of airbrakes and an enclosed single-seat cockpit.[1] The Camel first flew at Ratcliffe in Leicestershire in 1939.[2] In 1949 the Camel was registered to Alexander Ivanoff as G-ALLL.[3]

Accidents

On 19 August 1951 the Camel was destroyed in a fatal mid-air collision with another glider over Dunstable.[4][5] The pilot, an instructor with the London Gliding Club, was killed when the Camel suddenly descended on top of an EoN Olympia glider.[5] The pilot of the Olympia, from the South Downs Gliding Club, took evasive action when he saw the Camel descend; the glider lost four foot of wing tip but landed safely.[5] The Camel did not have a certificate of airworthiness, which was not a compulsory requirement. The Deputy Coroner recorded a verdict of accidental death, saying "there was no evidence that either glider was anything but airworthy".[6]
