Titan Submersible: Hopes fade as only four hours of oxygen left

Newfoundland: Hopes of locating the missing Titan Submersible in ocean depths are dwindling, as the remaining oxygen supply is only sufficient for a few more hours.

After receiving the signals from the submarine, maritime and aerial vessels from the United States (US), Canada, and France have scoured an area of ten thousand square miles in the open sea.

However, the exact location of the submarine remains elusive.

Experts state that even if a rescue team manages to reach the submarine, bringing it back to the surface would be an extremely challenging task.

Five individuals, including two Pakistanis, are on board the tourist submarine.

Former US Navy Commander David Marquet, an expert in submarine operations, cautioned that the recent sounds detected do not appear to be emanating from the Titan submarine.

 He stated, "I don't believe it's their noise; it could just be natural sounds."
