thread wander ....once heard a story that the Concorde was built on the same jigs as the scrapped TSR2 , seems unlikely , but possibly the wings had some similarity since they were both designed and built near Bristol , (Filton? /Fulton? )

Yes but that were the sonic boom you heard not the engines.

What I heard was a very loud engine noise that could only come from a low flying aircraft, no sighting and no sonic boom if it was going so fast (mach1 +) to have come, been and gone before the engine noise arrived.
