Titanic director and Explorer-in-Residence of the National Geographic Society James Cameron recently constructed a 43-inch-wide "capsule" that he climbed into, then had dropped to the bottom of a five-mile-deep trench off the coast of Papua New Guinea. His next goal is to get dropped into a seven-mile-deep trench, so he can look at the creepy deep sea animals that live down there. So, now we know James Cameron isn't claustrophobic, aquaphobic, ichthyophobic, or nyctophobic.
