One of things not much thought about with the A380, great aeroplane that it is, is the lack of airports able to handle it. A large aircraft diversion stretches any airport not accustomed to handling one so an A380 in BAKU is a headache for the airport, airline and passengers.
Why not simply continue until reaching a more suitable airport, after all the A380 has 4 engines and is apparently designed to reach a such and not divert into any hole ....
(sorry, is only meant to make the super-jockeys jump ..... )
