The de Havilland DH.88 Comet was a twin-engined British aircraft designed for the 1934 MacRobertson Air Race. Three examples took part in the race and one of them (G-ACSS) won it. The type set many aviation records during the race and afterwards, as a pioneer mail plane. The DH.88 might have been the only wooden British high-performance monoplane, but for a shortage of metal for aircraft construction during the Second World War. Experience with the DH.88 would later be put to use in designing the DH.98 Mosquito, also a twin-engined monoplane of wooden construction.
