This is the first comprehensive, well-illustrated documentation on the Do 335, one of the milestones in German aviation history.The Do 335 was developed by Dornier as a heavy fighter in 1943.One of the last high-performance piston-engined aircraft designed, the Do 335 was powered by tandem fore-aft engines, a concept proven in numerous Dornier flying boats.As a result of this configuration, drag was reduced to little more than that of a single-engined aircraft, enabling the Do 335 to achieve very high speeds.The Do 335 represented the apex of propeller-driven aircraft in the Second World War.
