“Walter Mittys with Everest dreams need to bear in mind that when things go wrong up in the Death Zone--and sooner or later they always do--the strongest guides in the world may be powerless to save a client's life; indeed, as the events of 1996 demonstrated, the strongest guides in the world are sometimes powerless to save even their own lives. Four of my teammates died not so much because Rob Hall's systems were faulty--indeed, nobody's were better--but because on Everest it is the nature of systems to break down with a vengeance.”
