A submersible watercraft bearing five people on board has reportedly disappeared without a trace after it set out on Sunday to explore the site of the Titanic shipwreck in the North Atlantic.
At a news conference on Tuesday afternoon, Capt. Jamie Frederick of the U.S. Coast Guard estimated that there was only about 40 hours of breathable air left on the vessel.
The American and Canadian Coast Guards, commercial vessels and aircraft have been involved in searching for the missing vessel.
