I have a number of thoughts about this. Without trying to 'out' myself, I was previously the Secretary of a State Deer Hunting Association and, of course, I'm a helicopter pilot. I have conducted heli-hunting trips.
How far do we take our briefings (without trying to blame the pilot)? How far do we brief a passenger before we land or after landing about a particular confined area or dangerous spot? How much do we test the dextrity of a passenger before we let them get themselves, gear and a rifle on and off a helicopter? Was age and experience a factor?
How much is plain bad luck when a bloke slips on a wet patch of ground? If there wasn't a helicopter involved, it would be easy to say it was just bad luck. But there is a helicopter involved. It could happen anywhere; heli-hunting, heli-skiing, heli-fishing...
Life is a risk. My condolences to the family,
and the pilot.
