Crazy. You never know what could happen. Even bomber placements could fail if the rock fractures or displaces slightly. I wonder how many pieces he had below him.....being it was a moderate pitch, he may have made a decision I've made many times and just foregone some pieces. As I've gotten older, and have 3 kids, I no longer make decisions like that. I'm not judging him, just wondering about the specifics. Horrible when things like this happen. My buddy's uncle, vet of many Himalayan climbs, died when he tied into a double rope rappel as if it were a single rope....crazy things happen to the best of us.
