James Cameron, director of huge hits like “Avatar” and “Titanic”, went on a history making dive this weekend. After a two and a half hour descent, he spent over three hours at the bottom of Challenger’s Deep, a seven mile deep trench in the western Pacific Ocean.

Mr. Cameron was the first person to ever reach the bottom of Challengers Deep alone. At 35,768 feet, Challengers Deep is the deepest known point in Earth’s oceans.

In order to safely make it to the bottom of Challengers Deep, Cameron piloted a 24 ft. deep-diving submersible. With 2.5 inch thick steel walls, the submersible was tested to be able to withstand 16,500 pounds of pressure per square inch!

Here is a video that exemplifies just how deep James Cameron went:



When he finally made it to the bottom, he was able to tweet this: “Just arrived at the ocean's deepest pt. Hitting bottom never felt so good. Can't wait to share what I'm seeing w/ you @DeepChallenge”
