A KLM DC-10 one morning was inside the outer marker (as it was in those days) for 10L at Heathrow when the pilot announced that he wished to divert to Amsterdam. We never found out why.
In this example would anyone apart from KLM and the Dutch authorities have a right to know the cause(s) and Reason(s) ? Or is it no-one's business and the captain made a decision and that's that ?
