In November 1940, a remarkable prototype aircraft made its maiden flight from an airstrip north of London. Novel in construction and exceptionally fast, the new plane was soon outpacing the Spitfire, and went on to contribute to the RAF’s offensive against Nazi Germany as bomber, pathfinder and night fighter. The men who flew it nicknamed this most flexible of aircraft ‘the wooden wonder’ for its composite wooden frame and superb performance. Its more familiar name was the de Havilland Mosquito, and it used lightning speed and agility to inflict mayhem on the German war machine. From the summer of 1943, as Bomber Command intensified its saturation bombing of German cities, Mosquitos were used by the Pathfinder Force, which marked targets for night-time bombing, to devastating effect. This book traces the contrasting careers of the young men of 627 Squadron.
