While I agree that the Hurricanes and Spitfires could be flown and operated in civilian hands, I question that the same could be said for the Lancaster. The Sally B people are facing big funding problems, while the France-based B-17 is now grounded. If industry continued to offer the support, fine, but industry are not always so keen to support privately operated concerns, as the Vulcan To The Sky Trust have found in the past.
Having said all that, all my best wishes and good luck for the East Kirkby Lancaster and the Coventry Shackleton, and I look forward to seeing them both airborne.
