The missing Titanic submersible may have less than 20 hours of oxygen left, risking the five lives inside, an admiral has said.
Rear Admiral John Mauger from the US Coast Guard said that five people on board the submarine-like vessel likely will run out of oxygen tomorrow morning, he told the BBC.
Two British-based Pakistanis, a billionaire Brit, a Frenchman and an American pilot have been trapped in the Atlantic Ocean since Sunday after they set out to view the Titanic shipwreck.
