Design and development
The conversion commenced in January 1951 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.
Air racing history
The aircraft was bought by Fred Dunkerley's Oldham Tyre Cord Company in January 1951. It was modified to M.77 standard, and first flown by Dunkerley in air races during the Goodyear Air Challenge Trophy at Shoreham on 28 August 1954. He won the SBAC Challenge Cup at Yeadon, West Yorkshire in 1956 and the King's Cup Race in 1957 with a top speed of 228 mph (367 km/h).
The Sparrowjet was severely damaged in a hangar fire at Upavon, Wiltshire in July 1964. In 2004 it was under rebuild in the Bristol area using discarded components from the 1950/53 conversion. The rebuild was still ongoing in early 2012.
