John,
I suspect it an Alpine machine as well. And yes, I know Alpine owns Canadian Mountain Holidays.
But unfortunately, when you are doing 120 takeoffs and landings a day (typical for heli-skiing) and the customer is grinding your ass for every 1/10 of a minute (typical Canadian heli-ski customer) this type of flying becomes pretty common.
Anyway, clearly the a/c was light so he could have lost an engine at any point and continued. Looking at the clouds I suspect the wind was calm or nearly so.
So, ... rock on dude
