Unprecedented 3D Scans Reveal New Insights into Titanic's Sinking.

A team of researchers spent six weeks last summer mapping the whole Titanic shipwreck and the surrounding 3-mile debris field, resulting in a 10 times larger than any underwater 3D model ever attempted before. The resulting data, including 715,000 images, is an absolutely one-to-one digital copy of the Titanic in every detail. The new technology will help researchers work out details of how the Titanic met its fate and allow people to interact with history in a fresh way.
