The family of missing British billionaire Hamish Harding have said they have “great faith and trust” in rescue teams, as the US Coast Guard expands its search for the submersible tourist vessel he is on into deeper waters.
There may be as little as 52 hours of emergency oxygen left aboard the submersible, named Titan, which lost communication with tour operators on Sunday while about 435 miles south of St John’s, Newfoundland, during a voyage to the Titanic shipwreck off the coast of Canada.
