I was scared many times on Everest, but this is all part of the challenge. When I fell down a crevasse, it was pretty scary.

Many people have been getting too casual about climbing Everest. I forecast a disaster many times.

No one remembers who climbed Mount Everest the second time.

I like to think of Everest as a great mountaineering challenge, and when you've got people just streaming up the mountain - well, many of them are just climbing it to get their name in the paper, really.

As far as I knew, he had never taken a photograph before, and the summit of Everest was hardly the place to show him how.

On the summit of Everest, I had a feeling of great satisfaction to be first there.
