Question

Numerous everest expedition have failed. why?​

Answer 1

Answer:

People die every year on Everest from falls, storms, avalanches, lack of oxygen, freezing or underlying health issues. But this year stood out because so many of the deaths happened while a climber was on the descent from the summit on clear weather days.

Answer 2

Explanation:

FATALITIES

First off we cannot ignore that, sadly, people die year on year on Everest. Interestingly there is no direct correlation between numbers on the hill and deaths that happen every year – so one cannot come up with a straight %age figure. Partly this will be due to variables (people, their experience, their acclimatisation rotations etc) but also will be due to the variances every year with weather conditions, route conditions and, in particular, how people fare on summit day.

There would appear, however, to be a direct correlation between fatalities and experience (or lack of it) as well as fatalities and cheap operations on the mountain.

More people die as a result of high altitude and / or exhaustion than any other reason. Falls account for the next highest %age closely followed by exposure. In reality falls may well be down to human error and possibly a result of either complacency or lack of experience. I’m not entirely sure how exposure can be differentiated from high altitude and exhaustion because, surely, an exhausted climber who sits down and can’t move … will eventually become a cold climber who can’t move. So, personally, I’d say that exposure is right up there with the high altitude and exhaustion issue.
