Rescuers in a remote area of the Atlantic Ocean are racing against time to find a missing submersible before the oxygen supply runs out for five people who were on a mission to document the wreckage of the Titanic. Despite an international rescue effort, US Coast Guard officials said the search covering 26,000 square kilometres had turned up no signs of the lost sub known as the Titan, but they planned to continue looking. Authorities reported the carbon-fibre vessel overdue Sunday night, setting off the search in waters about 700km south of St John’s, Newfoundland. Aboard were a pilot, renowned British adventurer Hamish Harding, two members of a Pakistani business family, and a Titanic expert. The submersible had a 96-hour oxygen supply when it was put to sea at roughly 6am Sunday, according to David Concannon, an adviser to OceanGate Expeditions, which oversaw the mission. That means the oxygen supply could run out tomorrow night (NZ time). Titanic tourist submersible missing graphic CBS News journalist Da
