Titanic's Lost Sister

Program Overview


Titanic, the most famous of the three ships owned by the White Star Line, was claimed to be "practically unsinkable." When Titanic sank in 1912, construction on her sister ship, Britannic, was interrupted so she could be overhauled to comply with new, post-Titanic regulations. Yet in 1916 Britannic sank within less than an hour. No one knows why. Some evidence suggests the ship was intentionally struck by a torpedo, while other evidence shows it accidentally hit a mine. In this program, explorer Robert Ballard seeks the point of impact that triggered Britannic's demise. Using his "debris field theory," which describes how the ocean current distributes sinking debris in a specific pattern on the ocean floor, Ballard follows the trail of wreckage predicted by his theory in search of answers.
