TITAN SUB UPDATES

'Catastrophic implosion' kills all five aboard Titan sub

A deep-sea submersible carrying five people on a voyage to the century-old wreck of the Titanic was found in pieces from a "catastrophic implosion" that killed everyone aboard, the US Coast Guard said on Thursday, ending a multinational five-day search for the vessel.

A robotic diving vehicle deployed from a Canadian ship discovered a debris field from the submersible Titan on Thursday morning on the seabed some 1,600 feet (488 meters) from the bow of the Titanic, 2 1/2 miles (4 km) beneath the surface, in a remote corner of the North Atlantic, US Coast Guard Rear Admiral John Mauger told reporters.

The Titan, operated by the US-based company OceanGate Expeditions, had been missing since it lost contact with its surface support ship on Sunday morning about an hour, 45 minutes into what should have been a two-hour dive to the world's most famous shipwreck.

Five major fragments of the 22-foot (6.7-meter) Titan were located in the debris field left from its disintegration, including the vessel's tail cone and two sections of the pressure hull, Coast Guard officials said. No mention was made of whether human remains were sighted.

"The debris field here is consistent with a catastrophic implosion of the vehicle," Mauger said.

Even before the Coast Guard's press conference, OceanGate issued a statement saying there were no survivors among the five men aboard the Titan, including the company's founder and chief executive officer, Stockton Rush, who was piloting the Titan.

The four others were British billionaire and explorer Hamish Harding, 58; Pakistani-born businessman Shahzada Dawood, 48, and his 19-year-old son, Suleman, both British citizens; and French oceanographer and renowned Titanic expert Paul-Henri Nargeolet, 77, who had visited the wreck dozens of times.

"These men were true explorers who shared a distinct spirit of adventure, and a deep passion for exploring and protecting the world's oceans," the company said. "Our hearts are with these five souls and every member of their families during this tragic time."

Rescue teams from several countries had spent days scanning thousands of square miles of open seas with planes and ships for any sign of the Titan.

Intense worldwide media coverage of the search largely overshadowed the aftermath of a far greater maritime disaster stemming from the wreck of a migrant vessel off the coast of Greece last week, killing hundreds of people.

Sounds from the deep

Mauger said it was too early to tell when Titan met its fate. The search operation had sonar buoys in the water for more than three days in the area without detecting any loud, violent noise that would have been generated when the submersible imploded, Mauger said.

But the position of the debris field relatively close the shipwreck and the time frame of the last communication with the Titan seemed to suggest the failure occurred near the end of its descent on Sunday.

The US Navy separately acknowledged that an analysis of its own acoustic data had detected "an anomaly consistent with an implosion or explosion" near the submersible's location when its communications were lost.

"While not definitive, this information was immediately shared" with commanders of the search mission, a senior Navy official said in a statement first quoted by the Wall Street Journal.

The Journal, citing unnamed US defense officials, said the sound was picked up by a top-secret system designed to detect enemy submarines.

In an interview with Reuters on Thursday, filmmaker James Cameron, who directed the Oscar-winning movie "Titanic" and has ventured to the wreck in submersibles himself, said he learned of the acoustic findings within a day, and knew what it meant.

"I sent emails to everybody I know and said we've lost some friends. The sub had imploded. It's on the bottom in pieces right now. I sent that out Monday morning," he recounted.

Sonar buoys dropped by aircraft had picked up some sounds on Tuesday and Wednesday that temporarily offered hope that the Titan was still intact and that its occupants were alive and trying to communicate by banging on the hull.

But officials said analysis of the sound was inconclusive and that the noises probably emanated from something else.

"There doesn't appear to be any connection between the noises and the location on the sea floor," Mauger said on Thursday.

Remote-controlled vehicles

Robotic craft on the seabed will continue to gather evidence, Mauger said, but it was not clear whether recovering the victims' remains will be possible given the nature of the accident and the extreme conditions at those depths.

The search had grown increasingly desperate on Thursday, when the submersible's estimated 96-hour air supply had been expected to run out if the Titan were still intact, a countdown that proved irrelevant.

The RMS Titanic, which struck an iceberg and sank during its maiden voyage in 1912, killing more than 1,500 people aboard, lies about 900 miles (1,450 km) east of Cape Cod, Massachusetts, and 400 miles (640 km) south of St. John's, Newfoundland.

The undersea expedition to the wreck, which OceanGate has been operating since 2021, cost $250,000 per person, according to the company's website.

Questions about Titan's safety were raised in 2018 during a symposium of submersible industry experts and in a lawsuit by OceanGate's former head of marine operations, which was settled later that year.

The sweeping search covered more than 10,000 square miles of ocean. On Thursday, the deployment of two specialized deep-sea robot vehicles expanded the search farther into the ocean's depths, where immense pressure and pitch-black darkness complicated the mission.

The fate of the tourist submersible captured global attention in part due to the mythology surrounding the Titanic. The "unsinkable" British passenger liner has inspired both nonfiction and fiction accounts for a century, including the blockbuster 1997 movie, which rekindled popular interest in the story.
