During the climb, Simpson fell and broke several bones in his leg, crippling him. His friend, determined to find a way to get Simpson home, tied their two lengths of rope together (each was 150 feet) and lowered his friend down the mountain 300 feet at a time. When Simpson failed to respond to Yate's signal to retie the rope, Yates made the agonizing decision to cut the rope.

Sherpa Jamling Tenzing Norgay was Climbing Leader for the 1996 Everest IMAX Filming Expedition and summitted the Mountain that year. He's also the son of Tenzing Norgay, one of the first men in history to summit Mt. Everest. In his book, Touching My Father's Soul, Jamling Norgay recounts his 1996 Mt. Everest ascent: the climb and its familial meaning. He now heads Tenzing Norgay Adventures, which is based in India. This interview originally aired April 19, 2001.
