English explorer George Mallory dreamed of conquering Mount Everest. He organized an expedition, but it failed. A second attempt also failed. A third expedition, launched after the most extensive preparation possible, was most tragic of all. An avalanche killed Mallory and most of his team. Back in England, friends invited the survivors to a banquet honoring Mallory and his valiant group. At its close, a surviving team member stood and looked around the room at photos of Mallory and his slain comrades. Then, in tears, he turned to face a huge picture of Mount Everest behind the banquet table. "Mount Everest," he said, "you defeated us once, you defeated us twice, you defeated us three times. But we shall someday defeat you, because you can't get any bigger, and we can!"
