Yeah, the deaths from the past couple of weeks have come from mismanagement of the death zone. Every climber knows he might die on Everest, but if you throw in a logjam of people at 29,000 feet the risks become much greater. Under typical circumstances, not bottleneck, and reasonably good weather, the vast majority of these climbers who died would have made it back alive, like most of the 250 - 300 other climbers have this month.
