Actually there is no problem if you think outside of the box.
If you are stranded on a mountain with four other guys during the storm of the century the logical answer is obvious.
Instead of cuting that rope with that knife you use that knife to kill other 4 guys.
But you must plan this so that you catch them by suprise with that knife.
Once they are dead you will have enough warm clothing to complety cover yourself beneath a very thick layer of cloths. So that you have a chance to survive the storm.
When the storm passes you can take your time and dig a deep hole in snow or better soil if there is any. So that you can bury your comrades and their cloths.
Once you are done you can get off the mountain and claim that you got seperated from the group and that you don't know what happened to them and you have survived by pure luck since you have managed to hide between the rocks. What in a way is true it just that you have wrap yourself in half a meter of very warm cloths.
Most people who are climbing on this kinds of mountains are not doing it in their country so no one will be suprised if you move far away from the crime scene indefinitively.
Also many of those mountains are in third world countries so they will probably not even start a search to find the missing corpses. If you are in a developed country then you must make everything faster with more calculation. But you will know in which part of the world are you so this should not be a problem.
Even if you get caught someway what is not too likey your chances of survival are stil much better then in the helicopter case where you surely die.
So judging from the thread I dare to say that NTs failed at logic COMPLETELY!
