I guess one (slightly) positive is there are plenty of preserved Vixens around to get some airframe and other parts from, Notwithstanding of course that most of them will not have flown for some 45 years and corrosion etc will of course have taken it's toll and pumps, gearboxes etc will need extensive overhauls. However, some of the later frames operated by FR Aviation and RAE Llanbedr last flew only some 25 years ago.
XS590 has been preserved at Yeovilton and stored undercover most of the time too and I believe is also the last built Sea Vixen too. Potential boom donor maybe, swapping with the now cracked ones off XP924? All subject to being sound structurally and corrosion wise of course.
But then there is the money.......given their long association with the Sea Vixen I would love to see my old company FR Aviation (now Cobham) donating some cash and possibly resources given their large airframe and component overhaul business. Might be some good
PR for them....
