Surprised to hear that rumour. There is a facebook page someone has set up about bringing her to back to Bruntingthorpe and a comment from Denis Parker (who I used to see a lot back in the 90s at Brunty events), that its a HLF requirement which rules Bruntingthorpe out. Seems all very odd to me, if they have a Victor, VC10, Comet, Nimrod, Lightenings, Bucaneers etc, then a Vulcan seems to fit right in. The open days are already fantastic, an addition of a Vulcan would be even better - and getting a hangar built for all of them would be a great use of funds.
Well maybe if Wellesbourne gets redeveloped 655 could be move to Brunty by road, or even if Doncaster doesn't work out, 558 could be moved at some point in the future. Possible, but expensive:
