Filmmaker James Cameron emerges from the Deepsea Challenger submersible.
Cameron piloted his specially designed solo submersible to a site known as "Challenger Deep," the deepest part of the Pacific Ocean's Mariana Trench -- about 6.8 miles down.
Cameron is the only individual ever to complete the dive in a solo vehicle, and the first person since 1960 to reach the very bottom of the world in a manned submersible.
