Did the pilot have a medical condition that made any of that more likely?
The reason for the medical suspension was that he had some time previously "woken up in a confused state" and a mini stroke could not be ruled out. However no test had ever found anything unusual subsequently.
There seemed to be a judgement call that the injured hunter had a good chance of dying overnight if not rescued vs the risk of the pilot having a medical event.
[edit]
John Funnell reckons he made the right call. To me that counts for more than anything I've seen said here so far.
