'''Percy Sinclair Pilcher''' (16 January 1867 – 2 October 1899) was a [[British people|British]] inventor and pioneer aviator who was his [[United Kingdom of Great Britain and Ireland|country's]] foremost experimenter in unpowered flight near the end of the nineteenth century.

After corresponding with [[Otto Lilienthal]], Pilcher had considerable success with developing [[hang glider]]s. In 1895, he made repeated flights in the ''Bat'', and in 1896–1897 many flights in the ''Hawk'' culminated in a world distance record.

By 1899, Pilcher had produced a motor-driven triplane, which he planned to test at [[Stanford Hall, Leicestershire|Stanford Hall]] in [[Leicestershire]] on September 30, 1899; however, the attempt was delayed by mechanical problems. When he substituted a flight of ''Hawk'', it suffered structural failure in mid-air and he was fatally injured in the resulting crash, with his powered aircraft never having been tested.

Research carried out by [[Cranfield University]] in the early 2000s concluded that Pilcher's triplane was more or less workable, and would have been capable of flight with design modifications. This raised the possibility that Pilcher could have been the first to fly a heavier-than-air powered aircraft had he survived.
