James Cameron has set the World Record for the deepest solo dive by reaching the bottom of the Mariana Trench. He is the first to ever reach the bottom alone. (The first people to reach the bottom did so in a two man sub)

Engineers made the pilot’s chamber spherical because the shape can be both strong and light. They also made the steel 2.5 inches (6.4 centimeters) thick to withstand the crushing pressure of the deep. If they had made the chamber a cylinder, by comparison, the hull would have needed to have been three times as thick to stand up to the pressure.
