An unprecedented two-year scanning project has produced the first-ever "digital twin" of the Titanic wreckage, offering new insights into the 1912 disaster.

Titanic, which was owned and operated by the British company White Star Line, sank during the early hours of 15 April, with the scan also revealing the personal possessions of passengers that litter the surrounding seabed. The wreck is deteriorating rapidly under the water and could disappear completely within the next 40 years.

A new documentary reveals the incredible results of a project to create 3D underwater scans of the doomed ocean liner RMS Titanic, which sank 113 years ago.
