Hopes were fading for the five men on board the missing Titan submersible as the 96-hour oxygen supply dwindled and experts warned the chances of their recue were decreasing all the time.
More ships and expertise were scrambled to help find the missing deep-sea vessel, which lost communication on Sunday while about 435 miles south of St John’s, Newfoundland, during a voyage to the Titanic shipwreck off the coast of Canada.
OceanGate Expeditions estimated the oxygen supply on the 6.7m (22ft)-long vessel, which has British billionaire adventurer Hamish Harding on board, would last the crew of five 96 hours, giving rescuers a deadline of around midday on Thursday.
