"Caroline MacKenzie: From a medical standpoint getting you to the top of Everest is really about oxygen. And the lack of it. To give you the best chance of summiting you need to prepare your bodies for the thin air up there."

"Helen Wilton: That's the cooking tent, and over there is the toilet. It's a little bit drafty, but just remember that when the wind gets up here, you've got the same view that George Everest did."

"Doug Hansen: I'm climbing Mount Everest... because I can... because to be able to climb that high and see that kind of beauty that nobody ever sees, it'd be a crime not to."

"Anatoli Boukreev: We don't need competition between people. There is competition between every person and this mountain. The last word always belongs to the mountain."

"Everest is another beast altogether."

"Something beyond the power of words to describe."

"You my friends are following in the very footsteps of history..."

"Can you just listen up? Guys? We got 2,000 feet, 600 vertical meters to Camp Four. It's roped all the way, so I know you can make it. Now, once we get to the yellow band we're gonna regroup, put on the masks, turn on the gas. Make sense?"

"1996: Other commercial operators follow Rob Hall's lead, including Scott Fischer's Mountain Madness. More than 20 expeditions compete to summit Everest in the same two week window."

"Title Card: Edmund Hillary and Tenzing Norgay became the first climbers to summit Everest. Over the next 40 years, only top professional climbers attempted the same feat. One in four died."

"1992: New Zealander Rob Hall pioneered the concept of commercial guiding on Everest for amateur climbers. Over the next four years his team, Adventure Consultants, successfully led 19 clients to summit without a single fatality."
