What's harder, picking up some body parts off the ground like 5 times a year or flying a heli next to a cliff trying to pick someone out of the water who hopped over a guard rail? Not saying this guy did but lots of people do.
In the mid 60s, flew into that area in a Bell to pick up left overs from some swimmers at the top who ventured too far, too late and too sad. Chocked up the skids for a spell to facilitate collecting and on liftoff we got sucked into the upper falls and literally spit out. The pilot, Roy, who had over 10,000 hours of mountain time flying was pale as a ghost when we landed. Ah, the innocence of youth!
