Rescuers raced against time on Tuesday in search of a missing submersible carrying five people on a mission to document the wreckage of the Titanic, the iconic ocean liner that sank more than a century ago.
The United States Coast Guard is leading the search for the small craft, named Titan, in the remote North Atlantic Ocean where the Titanic struck an iceberg and sank in 1912, killing all but about 700 of the roughly 2,200 passengers and crew.
