Andy Harris and the oxygen bottles...SPOILERS!
I know that in reality there is thought that Andy Harris was suffering from delirium due to oxygen deprivation, which often happens on high altitude climbs.
Although they didn't really suggest this in the film, and one can only speculate, I did see something that I thought was a bit odd, especially for an experienced climber. Whether it was something that was done on purpose, or a simple movie goof, I have no idea.
When Andy was checking the oxygen bottles left by the Sherpas, and claimed that they were empty, he is seen shaking one. This makes zero sense, as oxygen doesn't liquefy under pressure at normal temperatures, nor at the freezing temperatures on Everest. Other gasses do, like propane and acetylene and others, but not oxygen. I found this interesting.
Did anyone notice this and found it odd? Is this a subtle attempt by the filmmakers to suggest that he was suffering from hypoxia? What I've read suggests that he was, and he mistakenly thought they were empty, but the movie doesn't make that distinction. They movie leaves it open to interpretation.
Time wounds all heels.
