"The de Havilland company conceived the idea of a wooden aircraft to take advantage of the underused resources and skills of the furniture industry at a time of great pressure on the conventional aircraft industry combined with wartime shortages of steel and aluminium. The Air Ministry was initially not interested in the innovative approach; de Havilland, under chief designer Ronald Bishop, developed the Mosquito on a speculative basis. The ministry became interested when they saw the Mosquito prototype's performance. Throughout the 1930s, de Havilland had established a reputation in developing innovative high-speed aircraft such as the DH.88 Comet mailplane and DH.91 Albatross airliner that had already successfully employed the composite wood construction that the Mosquito would use."
