The Waverider re-entry vehicle, based on the Blue Streak missile, was devised by Professor Terence Nonweiler of Queen's University Belfast, and was intended to be the manned spacecraft in the British space programme. The programme was cancelled by the Macmillan government, but the work on Waverider continued at the Royal Aircraft Establishment, Farnborough — mainly to establish Waverider's potential as a Mach 6 airliner. During this period (1960–1965) at least one Waverider was tested at the Woomera Test Range. There were rumours that free-flight tests were also conducted at this time. Tests of X and Y-winged projectiles (in effect, three or four Waveriders mounted back-to-back) related to the Waverider were performed at NASA's Ames Research Center.
