The De Havilland Mosquito made of wood was designed based on high-speed bomber shaking off fighter. The design of the Mosquito was completed in 1939. De Havilland had experienced producing "DH88 Comet" made of wood before, therefore they paid attention that the surface of wooden wing could be finished smoothly and the amount of aluminum could be saved. Two of Rolls Royce Merlin engines were selected as the source of power and the wood was used as the material of this fuselage. The parts with the metal were only the parts of the periphery of the engine and the landing gear.
