I recommend this mighty tome unreservedly' Journal of Aeronautical History 'A long overdue corrective of an extraordinary man' James Hamilton-Paterson 'A fine, deeply researched book' Military History Monthly In 1938, a thirty-one-year-old RAF pilot and engineer named Frank Whittle – given special leave to pursue his own startlingly original concept of flight – presented the Air Ministry with a written proposal for a revolutionary jet-powered fighter aircraft. A ready response might have changed the course of history, but Whittle got no reply. In this gripping and insightful biography, Duncan Campbell-Smith charts Whittle's success at building a pre-war jet engine against all the odds – and tracks his desperate struggle to have it launched into active service against Hitler's Luftwaffe. It arrived too late – but nonetheless transformed the future of aviation.
