Testing and Evaluation
The single aircraft XP841 flew for first time on 17 August 1961 at the Royal Aircraft Establishment Bedford, with J.M. Henderson at the controls. It was subsequently used for low speed research in support of the Concorde development programme while the BAC 221, (a modified Fairey Delta 2) covered high-speed research. The HP.115 was a very capable aircraft; pilots were able to demonstrate rapid changes of bank, while still safely retaining control at speeds as low as 69 mph (111 km/h). Despite two minor mishaps, the experimental programme was a very lengthy one continuing until 1974, providing significant data regarding delta wing operations on takeoff and landing.
Neil Armstrong was due to fly the HP.115 as a test pilot in 1962, but after his selection as an astronaut, NASA refused him permission to fly the aircraft. He eventually flew it in 1971.
