I already said this about 5 pages ago.
But, before that they were heading basically straight towards it. It's possible that one or other has brain fade and configured the plane for landing at the old airport while the other was preparing to turn and land at the new airport. It's easily done - how many times have you moved house and ended up driving to the old one, maybe weeks later?
By the time such an error was realised it might be too late to correct it. The difference in seniority may also have led to a delay. Only a theory, but in the absence of a concrete cause it cant be discounted and it doesn't appear to be mech failure.
