Researchers find Titanic-warning shipwreck

During World War I, a German torpedo sunk the steam-powered SS Mesaba in the Irish Sea.

The ship may have been forgotten but for its connection to the 1912 Titanic catastrophe.

The Mesaba shipwreck was found by Bangor University on Tuesday.

Mesaba was a commercial ship in Titanic's seas.

The Mesaba warned the Titanic of thick pack ice and big icebergs, according to Encyclopedia Titanica.

The bridge never received the notification. The Titanic hit an iceberg and sunk that evening, killing 1,500 people.
