Thanks for your answers and siteswhere I could find revews. I really enjoy them and I agree with must of the doubts expressed in those reviews. I still admire the author's endurance and ability to get out of the mountains all by himself. I don't think that I could have endured that ordeal in his condition.
One thing that bothers me is his lack of preparation and lack of survival equipment in his plane. Also he did'nt take with him some of the few things in the plane that could had helped him maybe to have some fire, or drink water, or rope to help him construct a shelter.
Somethings that I found hard to believe is the part about falling and holding himself up the ridge with so many fractures, and the climbing of the tree.
Finally why did he changed his walkout plan and went in a different direction than agreed with the guy that stayed behind for no apparently good reason at all?
