After Mac Brazel found remnants of a strange object on his ranch in New Mexico in July 1947, the tiny town of Roswell would never be the same. As federal authorities descended and removed all traces of the silvery object, rumours about UFOs spread like wildfire. Authorities were quick to deny any out-of-this-world link, dismissing the flying object as a weather balloon. But to this day, some still swear the government is hiding something big: if not a UFO, perhaps a top-secret spying device, or weapon of war that might have blown this hamlet to bits.
Academy Award-winning director James Cameron leads a team of underwater explorers on a series of historic dives to document the remains of the world's most famous shipwreck. Using two, $20-million research subs, four mini-robots, a seafloor-to-satellite data system and a suite of the most advanced cameras and lights, Cameron's team provides real-time images of the ship's interior, including hidden passageways and vast rooms that haven't been seen in over 90 years. Directing the robot explorers from inside his mini-sub - two-and-a-half miles under the Atlantic Ocean - Cameron plays the ultimate video game. Using piloting techniques perfected in earlier dives to other parts of the ship, he steers his 'bot down the Titanic's massive staircase toward the elaborate, electric-powered Turkish Baths - an impressive swimming and recreational complex that was a marvel of engineering at the time of the ship's construction. But less than 100 feet away, beyond a series of barriers, is an even more impressive sight - one of the last great, unseen places inside the Titanic.
