It seems a shame to see such an amazing aircraft retire. Surely it could be converted into a freighter? Just think how much more cargo she could take compared to a MD11 / 747. Perhaps even a military version? How many more troops she could accomodate compared to an A330 or 767.
All as said before, unlike the B747, originally built as a freighter, the A380 had weight problems from the start and its floors are simply not strong enough to convert it to a viable freighter, it is a pax aircraft, pure and simple.
Flew for an airline that took one of the test B767-300ER airframes, talking to the engineers it was a bit of a nightmare at times because it still had miles of wiring looms that had been used for tests but simply disconnected rather than be removed, all accounted for in the sale price. Made a difference to the weight and balance too.
