Sixty years ago, on the morning of May 29, 1953, climbers Edmund Hillary and Tenzing Norgay reached the summit of Mount Everest -- the first successful ascent of the world's tallest peak. Since then, many mountaineers have followed in their footsteps. Some have lost their lives in the attempt, while other adventurers have taken on additional challenges to set new world records.
