Author James Neal Harvey has been a pilot for more than 40 years and has owned a dozen aircraft (including a De Havilland Tiger Moth built for the RAF, a Stinson V-77 that flew in the Royal Navy, and a Messerschmitt Bf-108 that served in the Luftwaffe). Author of six previous books, his grasp of aero-dynamics informs the narrative, as he examines how Messerschmitt might well have changed the course of the Second World War.
