The FD2 may have been restricted to 'banging' overwater, but it's 'development', the BAC221, WAS allowed to go supersonic over the UK. There was a supersonic corridor notified over the Bedford Levels until at least 1980; it was in the RAE Bedford Flying Order Book.
To develop the original question (tongue in cheek) did the VTOL version of the Mirage, the Dassault Balzac, become the Scott-Furlong Predator?
