Titanica

Computer-generated imagery and other visualization techniques reveal how it would look if all the water was removed from RMS Titanic's final resting place.

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.

Documentary about the sinking of the Britannic during the First World War, examining how she ultimately came to suffer the same fate as her sister ship, the Titanic. The Titanic sank in April 1912, and her sister ship, the Britannic, ultimately suffered the fate, sinking in 1916 due to an explosion caused by an underwater mine. In the wake of the Titanic disaster, Britannic was re-engineered to be even stronger. And yet she sank in just 55 minutes - three times faster than Titanic. It's one of Britain's greatest untold disaster stories. Now on the 100th anniversary, presenters Kate Humble and Andy Torbet piece together exactly what happened in those 55 minutes. While Andy makes a dangerous dive to the wreck, Kate speaks to descendants of the survivors. The characters she uncovers include Violet 'Miss Unsinkable' Jessops, who survived both Titanic and Britannic, Captain 'Iceberg Charlie' Bartlett and lookout Archie Jewell, who miraculously survived while those around him died.
