The Miles M.77 Sparrowjet was a twin-engined jet-powered racing aeroplane built by Miles Aircraft by fitting Turbomeca Palas jets to the prototype Miles Sparrowhawk. The conversion commenced in December 1950 and the Sparrowjet first flew on 14 December, 1953. Other modifications included a new tail section and front fuselage (in place of the Sparrowhawk's single engine), fixed, faired-in undercarriage and a large clear canopy. The wing roots were modified to take the Palas engines.
The Sparrowjet won the SBAC Challenge Cup at Yeadon, West Yorkshire in 1956 and the King's Cup in 1957 with a top speed of 228 mph (367 km/h). In 1964 the Sparrowjet was destroyed in a hangar fire.
