NEWS ALERT: ‘They’re Probably Dead’

( – BREAKING NEWS ALERT: The tourist submarine that attempted to visit the Titanic shipwreck that disappeared during its journey to the 111-year-old wreckage deep in the Atlantic Ocean is still missing, and authorities believe the sub, called the Titan, might have run out of oxygen by now. However, search operations are still ongoing.

Still, unfortunately, as one expert said on background, “they’re probably dead by now.”

OceanGate Expeditions, the company that manages the Titan, informed the Coast Guard that the sub had enough oxygen for 96 hours. The CEO of OceanGate, Stockton Rush, was onboard the missing sub. The oxygen supply was set to run out on Thursday at 7:08 a.m.

Five passengers were aboard the sub when it disappeared, but their condition remains unknown. U.S. and Canadian officials are tirelessly working to locate the missing Titan sub, which vanished around 900 miles east of Cape Cod.

Thursday morning, a remotely operated vehicle (ROV) was deployed to search for the missing sub on the sea floor. The French vessel L’Atalante was also preparing its ROV to join the search.

Along with Rush, who was the sub’s pilot, the missing persons include British billionaire Hamish Harding, Pakistani tech and energy tycoon Shahzada Dawood and his 19-year-old son Sulaiman, and noted Titanic explorer Paul-Henri Nargeolet.

OceanGate reported to the U.S. Coast Guard about the missing submersible eight hours after it lost communication with its main ship, the Polar Prince. OceanGate said the sub disappeared less than two hours after its Sunday afternoon descent.

Unlike regular submarines, a submersible relies heavily on its main ship for navigating the deep sea. The Titan needed the Polar Prince to go to the bottom of the ocean and back.

If the passengers on the Titan panicked, experts believe they might have used up their 96-hour oxygen supply sooner.

Mike Tipton, a specialist from the U.K.’s Portsmouth University, explained to Insider that humans can survive without oxygen for about three minutes. A lack of oxygen can cause restlessness, headaches, confusion, shortness of breath, blue fingertips, increased heart rate, and eventually, unconsciousness. Brain damage can occur after three minutes without oxygen, leading to death.

Tipton also warned of the possibility of carbon dioxide poisoning inside the sub if the filtration system was damaged or ran out of power.

These horrific scenarios are among the three potential outcomes experts have predicted for the missing tourist group. The U.S. Coast Guard has considered the possibility that the Titan may have resurfaced but can’t communicate its location, or it may still be underwater, stuck on the way to the Titanic shipwreck site located 12,500 feet below the ocean’s surface.

Coast Guard Capt. Jamie Frederick told reporters on Tuesday, “If it’s on the surface, we’re fairly sure we’re going to be able to find it.” But how long the passengers could survive if drifting on the ocean’s surface is still unclear.

Titanic expedition leader G. Michael Harris warned the families of the five passengers to prepare for the worst-case scenario, which he thought could be a breach in the Titan’s hull. Harris told Fox News, “Worst situation is something happened to the hull. Our fear is that it imploded at around 3,200 meters,” or 10,500 feet.
