The North American X-15 was the record-breaking high-speed and high-altitude research aircraft that played an important part in the race to the moon. In this lecture the test pilot who pegged up most ‘firsts’ in the X-15 gives his British peers insights into the aircraft’s flight test programme, including the aircraft’s stability and control and handling qualities, and goes onto describe the cockpit set-up and the programme’s use of simulation. He also explored the aircraft’s and the programme’s early objectives and the challenges facing those working on the aircraft, such as those caused by aerodynamic heating.

Robert M. White addressed the Third Meeting of the Royal Aeronautical Society’s Test Pilots’ Group on 11 December 1964. The lecture was introduced by Bill Bedford FRAeS, the recording was digitised thanks to a grant from the RAeS Foundation and the podcast was edited by Eur Ing Mike Stanberry FRAeS.
