Dylsexlic,
It can fit but crushing the runway is not what the airports will allow to happen. Realize this, an A380 that diverts to its ETOPS airport for whatever reason will shut down the entire ETOPS line because once down it won't be able to leave the runway. All of the sudden every aircraft that claimbed that airport as and ETOPS possible now has to recalc everything.
I was not putting the A380 down. All I said was it's going to take awhile to adjust the system.
It's kinda like buying a car and then they tell you "oh by the way, there are no roads for you to drive on"

"Well cept a few and they are here, there and far between."
