The exact time when the Titan sub crew will run out of time has been revealed.

After using the majority of oxygen reserves, the five crew members of OceanGate’s doomed submersible have just hours left to be rescued before they run out of breathable air.

According to the US Coast Guard, Titan will run out of oxygen on June 22 at 7.08 am EST or 4.08 am PDT.

This means that, as of this writing, the rescuers have just around eight hours of time left to both located the submersible and pull it to safety.

Despite the grim projections, officials insist that the mission is still one of a search and rescue nature, implying that they haven’t given up on finding the crew alive.

It was since the sub went missing on Sunday confirmed that the members of the crew include OceanGate CEO Stockton Rush, French explorer Paul-Henri Nargeolet, British billionaire Hamish Harding, Pakistani businessman Shahzada Dawood, and Dawood’s 19-year-old son Sulaiman Dawood.

As officials and rescuers race against time to locate Titan, at least two submersibles have been deployed to aid in search for the vessel that presumably stopped working or got trapped in debris somewhere along the journey.

“We have to remain optimistic and hopeful when we are in a search and rescue case,” US Coastguard Captain Jamie Frederick said.

“If we continue to search, potentially we could be at that point… And that’s a discussion we will have with the families long before I am going to discuss here publicly.”

The news comes after several “banging noises” were detected in the area where Titan was last seen. Unfortunately, all ROV operations so far have yielded negative results and the lost sub has yet to be found.
