Chuck Yeager, one of the most famous test pilots in US aviation history, takes listeners though the development of the rocket-propelled Bell XS-1 / X-1 in which he became the first man to fly faster than the speed of sound in level flight, including taking us through the test flights and politics of the X-1 flight programme. Yeager also discusses the flight tests of the X-1a, Northrop X-4 Bantam and McDonnell F-4 Phantom, then discusses some of his contemporaries in the test pilot seat, including working with Neville Duke on the Hawker Hunter. Yeager finishes off by talking about the Lockheed F-104 Starfighter altitude record and training astronauts to fly the machine.

The interview took place in 1979 and was conducted by Rodney Giesler and was edited by Mike Stanberry MRAeS.
