In reply to Tim:
I've read ITA, TC, plus Leni Gammelgard and Matt Dickinson's books.
My sympathies lie with Boukreev. Sadly, Fischer isn't here to confirm Boukreev's version of events that his early descent was agreed by him, although other members of the team have supported this view.
No-one else (I'll repeat that, NO-ONE, even those who _had_ used oxygen) was in any state to stage a rescue that night. Boukreev was able to make two long searches, alone, in a raging storm, resulting in the rescue of (I think) three people. He was also fit enough the next day to go up in the continuing storm and try to help Fischer.
Not for nothing was Boukreev given an award for his efforts by the American Alpine Club.

So, if you've read Into Thin Air, _do_ read The Climb. Not as exciting, but only fair to get both sides of the story.
