Talking about repairing aircraft, what about the BAC 1-11 that force landed on a motorway in Germany having suffered double engine failure on take off. The only problem was that the German Autobahn engineers never thought to design the loading gauge of the overhead bridges to clear British designed T tailed airliners...
Some oversight..... but that's for another thread.
Anyway, when one came in contact with the other, the bridge won and the tail came off.
I understand that BAC engineers decided on reviewing the remains, that the aircraft could be rebuilt, it duly was, and returned to service.
By all accounts it turned out to be (in it's second life) one of the best flying examples (re) built!!
And to be fair, that would be a crew I would want to fly with again.
