1. AS350, towing a 33ft geophysics survey bird on a 100ft string in the Kiglapait Mountain range, Northern Labrador, Canada. We went out at dawn to get 20 lines or so done in a 3600ft cirque that hadn't let us in for a week due to high winds. Cirque valley was full of snow and it was summer (you mountain boys already know the rest). The cold air decided to rush out of the cirque while we were descending vertically down the cirque wall on Line 12. We lost 1300-1500 ft and recovered at the bottom.
2. SK61, Canadian Arctic. Blade pocket let go causing serious 1/rev all the way down to the creek bed.
3. B212, Cambodia, Jungle, Monsoon rain, lost, both low fuel lights on. While preparing the pax (14 Bangladeshi soldiers) for the landing (if one could find a place), and inevitably being taken hostage by the NADK, the UN camp we had been looking for came in view. Landed, tried to look cool like nothing ever happened, removed horseshoe, drank large amount of black rum.
