Jet : Sapere Books : 9781800557093 : 14 Mar 2023 : The remarkable story of the early days of jet development as told by the 'father of the jet engine', Frank Whittle. For aviation enthusiasts and readers of Ian Mackersey, Duncan Campbell-Smith and Graham Hoyland. On the evening of 15th May 1941, a small group gathered at RAF Cranwell in Lincolnshire to watch as the Gloster-Whittle E.28/39 made its maiden flight - Britain's first jet-engined aeroplane. This book chronicles the story behind that historic event. Sir Frank Whittle, who eleven years earlier, at the age of 22, had applied for his patent for a turbo-jet engine, here sets on record his own pioneering work and that of the small company, Power Jets Ltd, which he helped to form in 1936 to develop the engine. The dreams of his youth were brought to fruition in an invention that not only revolutionised military aircraft but set Britain ahead of the world in civil aviation, bringing the inventor a knighthood at the age of 41.
