Frantic search for Titanic submarine crew who have until 10am on Thursday before air runs out

The Independent says The families of five people missing in a submarine that vanished near the wreck of the Titanic have been handed a grim deadline of 10am on Thursday for rescuers to find their lost loved ones alive in the depths of the Atlantic Ocean.

A frantic search for the OceanGate Expeditions submarine became an increasingly desperate race against time as it entered its second day on Tuesday, as officials said those on board would have already used more than half of their 96-hour oxygen supply.

Despite US, Canadian and French authorities having expanded what is the deepest undersea rescue operation in history to cover some 10,000 square miles of ocean, an adviser to the submarine firm warned that the extraordinary mission had been hampered by red tape, bureaucracy, and a lack of urgency on the part of US officials.
