Hollywood film director James Cameron has traveled to the deepest spot on Earth.

The director of Titanic and other films used a specially designed submarine called Deepsea Challenger Sunday to dive nearly 11 kilometers, about 200 miles southwest of the Pacific island of Guam.

Cameron sent the message “All systems OK,” to his support team on the ocean surface after reaching the bottom of the Mariana Trench.

He is only the third person to reach that depth. Swiss engineer Jacques Piccard and Don Walsh, a U.S. Navy captain, took a dive to the same spot in 1960. They spent about 20 minutes there but couldn't see much after their sub kicked up sand from the sea floor.

Cameron plans to spend six hours on the Pacific Ocean sea floor, collecting samples for scientific research and taking still photographs and moving images. He told the Associated Press in an interview that the water pressure on the submarine is so great that it would implode if it sprang a leak.

The Mariana Trench is 120 times larger than the Grand Canyon and more than 1.6 kilometers deeper than Mount Everest is tall.
