3 European Climbers and sherpa's have fist-i-cuffs high up on the mountain at Camp 3.
lol norty boys.
Camp 3 is way above 25,000 feet, well into the "Death Zone" where the body begins to die from oxygen shortage, which happens even when one uses bottled oxygen. Chances are the climbers became hypoxic, which causes personality change, poor judgment, and high-altitude sickness. If the climbers were sent back down, it was to save their lives.
Everest is not a walk in the park, even though it's not a "technically" difficult mountain to climb (you don't need a lot of rock-climbing experience). But the high altitude can be, and often is, deadly.
Jon Krakauer's "Into Thin Air" relates just how wrong things can go high up on Everest, where even experienced mountaineers can and do die very easily.
Anyone read the book
Three Cups of Tea by Greg Mortenson
A great book.
Coincidentally, Jon Krakauer also wrote a book about Greg Mortenson, called "Three Cups of Deceit." Good read.
