We hover taxi-ed to the side of the car-park and then followed the road down, about the same distance away from the skiers cars descending as our Dauphin friend is.
Then descended in a sideslip down the scree slope - again, probably about 10 feet agl until we broke out of the fog.
Same technique when flying to the wreck of Ansett 703 in a Squirrel - except going up rather than down - absolutely socked in on the day.
The average dashcam has a very wide angle lens - our special forces driving friend may have appeared to be closer than he really was.
As a previous poster said - hover and mosey - nothing to see here.
