What the 3D scan of the Titanic reveals about the doomed ship

A 3D scan of the Titanic reveals new details about its sinking, confirming that engineers worked until the very end to keep the lights on.
The scan, created from over 700,000 images taken by underwater robots, shows a porthole likely smashed by the iceberg, corroborating survivor accounts.
It also indicates that small punctures across a long length of the hull, rather than a single large gash, led to the flooding and sinking.
The scan reveals that the ship's boilers were still operational and steam was still flowing to the electricity system, suggesting engineers were working until the final moments.
The wreck is deteriorating rapidly and could disappear within 40 years.
