There is no way to make travel up there safe. There’s no real way to have a rescue team anywhere near there. People can only stay at altitude for brief periods of time, it’s just very dangerous up there.
And people climb Everest not despite it being risky, but because it is. As someone who climbs and hangs around lots of climbers, no one would want it to be a place where you can call in a rescue at all times. It would devalue the experience for most, perverse as that sounds.
The teams, Sherpas, and clear-thinking leaders turn you around before you get in serious trouble. They are there when some extra oxygen turns can prevent you from collapsing or revive you immediately after. One clearheaded individual can prod and push someone down when they can’t do it themselves. But wait too long and you can’t do that. The key up there is to keep moving and turn around before things get too bad.
Also, getting Sherpas, supplies, tents, fixed ropes, etc up there takes money that all these other groups paid and planned for. It’s harsh that this is the case, and it wasn’t the case in Sir Edmands time. This is the part that I have the hardest time dealing with, since you are essentially putting a price on someone’s life.
I don’t want it to sound like I’m defending all the actions of everyone up there. I think the whole zoo that Everest has become makes things like this inevitable, but that’s what has happened. Climbers (often foolish and deluded) go into this with their eyes open. I’m sure more could have been done for Sharp before he got that bad, but the guy was determined to summit and that seems to be the proximate cause. After that happened, I’m not sure what the options were.
And having never have been up that high I can’t say with any certainty what is possible and what isn’t. I’ve been to 18,000 and I know that I wasn’t thinking all too clearly at times, and I would have been much less effective if called upon for a rescue. I can’t imaging what it’s like at 28,500.
The rescue of Lincoln Hall, by all the teams on the north side of the mounatin, is nothing short of amazing. He managed to revive and contribute to his own rescue, which I’m sure improved the chances of success. It does make you question if a rescue of Sharp was possible (although it also appears that Sharp was in much worse shape). I’m not sure about the terrain enough to know what the route is like on that side. But all those Sherpas who performed the rescue (and it appears to have been all Sherpas) knowingly put their lives at risk to do this, and did it willingly. What they did is awesome in all respects.
