It's actually very typical for metal ships to break down in that deep of ocean. Wood ships are, paradoxically, the ones preserved on the deep sea floor.
That's cause wood ships are eaten by aerobic bacteria and metal ships are eaten by anaerobic bacteria.

The Daily Mail thought the ship was repairing itself and preparing to set sail once again some time in the future. They were banking on "Titanic sinks AGAIN!" And then blame it on immigration and explore in depth how it'd affect house prices.
