I did my last five years at Marham so I'll be sad to see her go but I guess it's inevitable really as I expect she's in a right state internally. It makes you wonder what some of the other large aircraft preserved outside are like, Waddington Vulcan?
Further afield I would hope the VC10 and C130 C3 at Cosford will survive a while longer being fairly recently retired but I expect they will eventually go a similar way? Likewise the Vulcans at various civvy sites up and down the country.
Although I have a soft spot for the Bev it was a fairly small fleet, operated a long time ago and is not well known by the public, it's also flipping big, all of which don't work for it sadly. No disrespect intended- I'd love to see it survive but I can't see it somehow.
At least a couple of Victor's have long term futures, the Duxford K1 (?) looked to be undergoing some pretty serious maintenance work when I visited last year
Hopefully parts of the Marham Victor will survive.
