"What it would involve to launch a rescue would almost be beyond the brain capacity of a person at high altitude."
Sorry, but this sounds like CYA bigtime, like the John Kerry stories of soldiers who "can't control themselves" and kill innocent people.
The excuse here is basically "You lose your mind on the way up and just keep going"? BS
This is going to sound harsh but it's not intended that way.
It's my understanding at that altitude it is physically impossible to carry someone down the mountain whose not able to walk themselves. Climbers know that once that last push to the summit starts either they get themselves back down to the highest camp and their tents(usually around 26,500 ft)or they die on the mountain.
That altitude is called the zone of death and for a good reason. It takes a superhuman effort to get yourself up and down. Having the strength to bring someone else down is not in the cards.
If they had tried there'd have been one or two more dead on the mountain.
