I really dont want to flog a dead horse but the last three posts miss the point. We agree the casualty needed medical assistance that night. I would have put in a team of two to carry in the kit to make the position safe, give shelter and provide medical support ready to evac the next day.
That needed one legal flight with pilot, unofficial navigator and medical team of two.
Any further medical crew were a luxury - OK insert them if it is safe and legal - but they were not needed that night
I think the facts we know are adequate to be confident this casualty did not need anyone to break the law.
