Director James Cameron completed a record-setting 6.8-mile solo dive to the bottom of the Mariana Trench off the coast of Guam–the deepest point on Earth. The Titanic mastermind began the dive at 5:15 a.m. local time and resurfaced around noon. Cameron spent around six hours collecting samples, before making the 70-minute return journey. The only other dive to that spot was in 1960; it took the divers five hours to reach the ocean floor and they spent only 20 minutes there before heading home. Cameron was inside a "vertical torpedo" sub and used a "slurp gun" to gather samples on the sea floor.
