The second biggest problem that the RAF faces with regard to storing and restoring old aircraft is keeping the airframes out of the cr*p weather we get for most of the year (June & July 2006 excepted!) until they are ready to deal with them properly. So has anyone on high ever considered some sort of arrangement with the Aerospace Maintenance and Regeneration Center (AMARC) at Davis-Monthan AFB, whereby selected airframes could be moth-balled there until somebody has decided on some positive course of action and then done it.
The biggest problem, as you already know, is the complete lack of interest by the powers-that-be, so I suppose this idea is a non-starter.
Yes, I know - and money.
