Not far from green boots is another guy that basically died during a discovery series. Different expedition, actually more of a pay to get you there and setup some basic supply caches on the route and then have fun on your own outfit more so than an expedition iirc, but they crossed paths both going up and down while he froze to death and the radio traffic made it into the show. Lots of others passed as well either not seeing him or thinking he was already dead.
They took a *expletive deleted*it load of flack over it. Mostly from people who have never so much as took a stroll on a nice path in the park, of course.
From what I just read, the reason they took flak for it was because they found him in trouble, but alive and still able to move, on their way up, while they were fresh, and left him there so they could complete their summit rather than abandon their climb to help him down.
I certainly hope they caught flak for it. Even if they had been unsuccessful at saving his life, making the attempt *should* be more important than getting your bragging rights for climbing a mountain.
