The de Havilland DH.98 Mosquito is a British multi-role combat aircraft with a two-man crew which served during and after the Second World War. It was one of few operational front-line aircraft of the era constructed almost entirely of wood and was nicknamed "The Wooden Wonder". The Mosquito was also known affectionately as the "Mossie" to its crews. Originally conceived as an unarmed fast bomber, the Mosquito was adapted to roles including low to medium-altitude daytime tactical bomber, high-altitude night bomber, pathfinder, day or night fighter, fighter-bomber, intruder, maritime strike aircraft, and fast photo-reconnaissance aircraft.
When production of the Mosquito began in 1941, it was one of the fastest operational aircraft in the world. Entering widespread service in 1942, the Mosquito was a high-speed, high-altitude photo-reconnaissance aircraft, continuing in this role throughout the war.
