Part 6: Untold Stories This is the personal account of the people and the tragedy. In never-before-seen footage, historian Charles Haas descends the depths of the North Atlantic and guides us on a tour of the Titanic. While recounting tales of triumph and struggle, we see among the many sites the doors where all passengers would have entered, peer through the porthole of a first class cabin, see the davits where the too few lifeboats hung, pause by the mailroom where the postal workers heroically died. Unique footage, letters, old stills, artefacts and new recreations help tell the human stories of the Titanic.
