According to the New York Post, OceanGate Expeditions, which operates the Titan sub and has its CEO Stockton Rush aboard the missing vessel, told the Coast Guard Sunday evening that the vehicle was equipped with only 96 hours of oxygen, with the timer running out around 7:08 a.m. Thursday. Despite authorities continuing to push forward with the search operation, the Titanic tourist submersible is believed to have run out of oxygen.
On Thursday morning, June 22, the Coast Guard confirmed that a remote-controlled vehicle "has reached the sea floor" and began looking for the missing submarine.
It went on to say that "the French vessel L'Atalante is preparing their ROV to enter the water."
British billionaire Hamish Harding, Pakistani tech and energy mogul Shahzada Dawood and his 19-year-old son Sulaiman, and renowned Titanic explorer Paul-Henri Nargeolet are among the missing, along with Rush, who was the ship's pilot.
The submersible went missing eight hours after it lost contact with its mothership, the Polar Prince, according to the US Coast Guard. OceanGate informed them of the situation.
According to OceanGate, the submarine vanished less than two hours after it sank on Sunday afternoon.
According to Insider, Mike Tipton, who is in charge of the extreme environments laboratory at Portsmouth University in the United Kingdom, humans can only survive for approximately three minutes without oxygen.
According to the expert, people may experience restlessness, headaches, confusion, shortness of breath, blue fingertips, increased heart rate, and eventually loss of consciousness when there is a depletion in the air supply.
Brain damage and eventual death can result from oxygen deprivation lasting longer than three minutes.
Tipton admonished the passengers that, in addition to the lack of oxygen, they could.
