I would like to invite you to watch one of movie of Everest collection…
Climbing Mt. Everest without (bottled) oxygen. Sometime between 1 and 2 in the afternoon on May 8, 1978, Messner and Habeler achieved what was believed to be impossible — the first ascent of Mt. Everest without oxygen.
Now a comment on this video. It consists of parts from the documentary ”Everest Unmasked”. In the documentary, the real dangers of this attempt are presented. Moving glacier, avalanches and serious health problems because of the low oxygen. To deal (to some extent) with the latter, extremely good physical fitness is undoubtedly needed in order to reduce the time exposed to the (very) low oxygen and not only. That’s all, enjoy the video.Update: After some thoughts i think a viewer discretion is advised might be needed. Needless to say, that what you see is performed by experts..
