Mount Everest, that's easy. I want to see someone go to Mars and climb Olympus Mons.

I don't know the numbers, but from what I've read/seen, the real killer would be the K2, which kills almost 1 in 4 climbers.

K2 and another mountain, those two are very dangerous. Add on top of that, I think no one has been able to climb K2 in the winter. 

Pfft, Mount Everest is nothing. Now Mauna Kea, that was tough. Needed my Iron boots and Zora tunic for that one.

Beat me to making a witty Zelda comment =p

The Annapurna I has a 38% death ratio.

People falling, that sounds nasty, especially if they aren't all recovered, imagine how much of a morale killer that must be to find a splattered guy right before you climb the mountain.

You are crazy to even consider climbing a 8,000m+ mountain. Mt. Everest(10% death rate), K2(20% death rate), Ana Purna(38% death rate). It would be really cool if you could ascend the mountains and base jump from their peak and land safely down onto the soft ground.

I'm not sure, but I think over 7000m is hard for them to fly, due to the lower air density.

It's called "gorunf effect", and (please correct me if I'm wrong) it's when the air pressure difference between the top and bottom of the rotors is not enough to push the copter higher.

Reaching this point depends on the design of the rotor. As such there are helicopters that can't go higher than 3 or 4.000 m while others, mostly experimental, have landed on the Everest and even reached the 12.000 m.
