While climbing in Chamonix in the French Alps at 17 years of age friend took a massive leader fall just before dark. We spent the night at 13500 ft on a 6 inch ledge. Next day hauled him back down to glacier to be picked up by a lama.
36 years later still remember that first helicopter ride, as the pilot must have been power limited and at time I thought he was having fun as he threw it off the cliff edge almost vertical, I now know better !!!
