Hubertus Strughold, the German physiologist hailed as the ‘Father of Space Medicine’, was later found to have experimented on live prisoners at Dachau concentration camp. John Derry, the first British pilot to break the sound barrier, died along with his crew in the crash that killed 29 spectators at the 1952 Farnborough Air Show. The history of the development of space medicine is one of breathtaking courage, foolhardy experiments and terrifying gambles with death, some won, some lost. Dr Gordon Sharp, who for years was one of our most prominent aerospace doctors, tells the story from the inside by focusing on the fearless individuals from the past who helped to make modern flying safe by daily risking their lives.
