Thanks Brit312 and ChristiaanJ.
Living in Bristol we used to see her go over on the way in to LHR and on a quiet day with the wind in the right direction we could sometimes here a very faint version of the "BaBoom" that was in the linked video.
Such a shame that they didn't keep at least one in a relatively easier to restore to flight condition and send it on the air show circuits with the Vulcan. With the talk of analogue FBW and PFCUs it reminded me of some of the Vulcan controls that I have read about, was there much technology transfer from the Vulcan to Concorde in the design stage?
