Search and rescue teams are racing to find a deep-sea vessel that went missing with five people on board during a dive to explore the wreck of the Titanic ocean liner.
The US Coast Guard is leading the search for the small craft, named Titan, in the North Atlantic Ocean. The remote area is where the Titanic struck an iceberg and sank in 1912, killing all but about 700 of the roughly 2,200 passengers and crew.
