At the beginning of the Second World War there was no thought of delivering planes by air across the Atlantic. It was assumed to be too costly and too dangerous, especially in winter. Despite this initial reluctance, between the fall of 1940 and the spring of 1945, Royal Air Force Ferry Command's mixed civilian and military crews flew almost ten thousand aircraft, mainly American-built, to operational squadrons overseas. In Ocean Bridge Carl Christie provides the first full account of the genesis, history, and importance of Ferry Command.
