“Titanic” director James Cameron returned to the surface Monday after a solo submarine dive to the deepest point in the world’s oceans that was hailed as the ultimate test of “man and his machine.”
Cameron plunged about seven miles (11 kilometers) to the bottom of the Mariana Trench in the western Pacific, where temperatures are barely above freezing and the pressure is a crushing thousand times that at sea level.
His trip was cut short because of a mechanical problem.
