I’ve always said that the most difficult thing about corporate rotary is when to take stock and say no!
That comment holds true for SAR and, I suspect, HEMS as well.
This is the sort of incident that is dissected well on military (and I'm sure civilian) Flight Safety courses - too much focus on achieving the task, poor weather, adverse cockpit gradient and a breakdown in CRM - leading to poor decision making - all ingredients we have seen so often in so many accidents.
Such dissections allow you to measure yourself against the decisions made - you can ask yourself how far down that same path would you have gone before you said no. If you get to the end and still don't see a problem - then you are the problem!
