A new National Geographic documentary, "Titanic: The Digital Resurrection," reveals unprecedented details of the Titanic's sinking using a revolutionary 3D scan of the wreckage. The scan, comprising 715,000 images, creates a highly accurate digital model, challenging existing theories. New evidence potentially clears First Officer William Murdoch's name, supporting accounts of his active role in lifeboat preparations before his death. The documentary premieres Friday on National Geographic.
