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.
