The twin engine, double seat aircraft was made primarily from wood, and was successfully used during and after the War. Between 1940 and 1950, over 7,700 Mosquitos were built. Because of its high speed and high altitude performance, the German air defences were almost completely unable to combat the Mosquito. As well as Great Britain, the Mosquito was also used by the USA, Canada, Australia, China, New Zealand, South Africa, Czechoslovakia, Yugoslavia and Israel.
