The first humans to descend into the Challenger Deeps were Jacques Piccard and Don Walsh. They were in a bathyscaphe called "Trieste." At 30,000ft (9000m), an outer window cracked, but in a display of awesome human courage, they continued the dive to the bottom, and Trieste held up. This took place in 1960.
