In the late 60s a Lightning went supersonic at an airshow in UK - it was flown by one of the Air Marshals who is accused of being the villain of the Chinook inquiry. He certainly did not get court martialled and I can't remember anybody else who did from that era either. Supersonic flight was allowed anywhere over Germany in that period provided one tried to avoid the Ruhr and it was not unusual for a boom to be dropped in UK although it was not permitted.
