Underwater robots map Titanic's final resting place

The first map of the entire three-mile by five-mile field of debris from the Titanic has been drawn by researchers using sonar and underwater robots.

They hope it will provide new clues about what exactly happened on the night 100 years ago when the liner hit an iceberg and plunged to the bottom of the North Atlantic. Up until now explorers had only known where the the bow and stern had landed, 13,000ft down on the ocean floor.
