No injuries, no damage, but a great deal of embarrassment all round. This sort of thing has happened before and will no doubt occur again. The case given below has its similarities, but the guy in question did actually make it to the correct airport.
AAIB Aircraft Accident Report 3/94 - Boeing 737-2Y5A, 9H-ABA, London Gatwick, 20 Oct 1993
I'm surprised the same thing hasn't happened at Mahon. Two airfields more or less side by side.
