Surely, whether the aircrat was landing or taxiing, if it ran off the runway or taxiway and repairs of some sort were required to either the airport facilities or the aircraft, it must be reported?
The airport authorities say they have the entire incident on videotape, so why all the cloak and dagger? What's so hard about releasing the footage to the airline and showing it to the VP?
It may be that he really doen't know about it, or it may be that he has not had an official report about it - these are two completely different things, so it could be that they are playing with semantics.
If AOT have it on tape, as they claim, then there is absolutely no question one way or another.
If the airport or the aircraft needed repairs, then it is a reportable incident, as it could impact the safety aspects of the aircraft concerned or of other users of the airport.
Simple - whats so hard about it?
