Titanic: The Nightmare and the Dream.

Decades after the RMS Titanic sank into the Atlantic, the dream of investigating the wreckage was finally realized by undersea geologist Dr. Robert D. Ballard. In 1986, only a single camera crew was allowed to accompany his historic expedition. Using high-tech cameras mounted on submersibles, this remarkable program takes viewers into the frigid depths nearly two and a half miles below the ocean’s surface, revealing spectacular color images of the ship’s once-luxurious interior.
