You misquote them slightly but I can forgive that....
They also sang:
‘A cripple walks in a straight line
An imitation of dignity
From despair to where’
I fear those may be the words you find yourself reflecting upon.
What is this unique aircraft, and why (in all that’s holy) a UK AOC..? Must you charter it?
Otherwise you’re running flat-out into a minefield with clown shoes on. (And I’ve been closely involved in doing extraordinary things on UK AOCs in the near-past, but when we hit on acquiring N-reg airframes we swiftly rejected taking on the miserable path you propose. We got them flying, in the end, by other means).
