The Shorts Sperrin was a low tech insurance policy by the RAF to ensure it had a stategic bomber if delays arose with the cutting edge Vulcan and Victor bombers. However, Valiant developed by Vickers took this role and only two Sperrins were built (used as flying test beds).
Short SC.1 - demonstration of both prototypes (XG900 and XG905) at Royal Aviation Establishment in Bedford. Short SC.1 (first flight 1957 (CTOL), 1958 (VTOL)) was the first British fixed-wing vertical take-off and landing (VTOL) aircraft. The SC.1 was designed to study the problems with VTOL flight and the transition to and from forward flight.
