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.
