You never know what the whole truth is. A dear friend of mine ( a VERY experienced and sought-after climber) died several years ago on Everest and is still there. The conditions often defy the imagination.
David Sharp, 34, was still alive at 28,000 feet. Double amputee Mark Inglis, told the news source: "He was in a very poor condition, near death. We talked about [what to do for him] for quite a lot at the time and it was a very hard decision. About 40 people passed him that day, and no one else helped him apart from our expedition. Our Sherpas (guides) gave him oxygen. He wasn't a member of our expedition, he was a member of another, far less professional one."..."The latest case is British David Sharp. David vanished on his summit bid last week, and the only reason the world knew was thanks to a blog entry by his team mate Vitor Negrete. Vitor dispatched that David had died, and reported 3 more climbers missing on the mountain. He was distraught by the situation, including the fact that his high camp had been robbed. 'All these events have affected me deeply – I even considered calling the attempt off,' he said. The next day, Vitor was dead."
