The last ‘ping’ from the sub was received yesterday afternoon above the wreck site. The submarine, which can hold up to five people paying $250,000 each for the trip, is estimated to have up to 96 hours of oxygen left, meaning the rescuers have a deadline of midday on Thursday to recover it. However there are growing fears if the vessel is stricken in the depths, it will be impossible to ever recover it.
Rear Admiral John W Mauger of the US Coast Guard said they are doing "everything" they can to find the submersible, saying it has one pilot and four mission specialists aboard with up to 96 hours of emergency oxygen on board."We anticipate that there's somewhere between 70 to the full 96 hours at this point," he said on Monday.
His cousin, Kathleen Cosnett, told The Daily Telegraph she saw Mr Harding as "daring" and "inquisitive", and that she was "devastated" to learn he was missing.
