Crash n Smash did it with the Vulcan that went to RAFM Hendon 40 years ago, but that wasn't with the intention of it ever being live again, so they chopped through the electric looms runs and cables at the joints when it was split......and that was still a huge undertaking. If its never going to be a live a/c again, why bother trying to move it, as there are plenty of dead Vulcan' already in museums?
I think the only way '558 will be leaving DSA is in bits in a load of skips.
