Recovery efforts were underway Friday after officials determined a “catastrophic implosion” killed the five people aboard a submersible that had been missing for days in a dive to the Titanic wreckage site.
Search crews remotely operating an underwater vehicle discovered a debris field Thursday morning in the general area of the Titanic “consistent with a catastrophic implosion of the vessel,” Rear Adm. John Mauger, commander of the First Coast Guard District, said in a news conference.
The debris was found about 1,600 feet from the Titanic’s bow on the sea floor. Mauger said it was too early to tell when the Titan imploded.
After the craft was reported missing, the U.S. Navy analyzed its acoustic data and found an anomoly consistent with an implosion near where the submersible was operating when communications were lost, Coast Guard spokesperson Briana Carter confirmed to USA TODAY. The information was shared immediately with the search commander. Still, the search continued for possible survivors.

What happened when the Titan submersible imploded?
The final moments of the Titan would have been swift – and unleashed amid a force difficult to comprehend, experts in physics and submarines told USA TODAY. Pressure at the depth of the Titanic — 12,500 feet down — is nearly 380 times greater than at the surface, said Luc Wille, a professor and chair of physics at Florida Atlantic University.
Even high-grade military submarines don’t wander around the ocean at full depth because it’s just too dangerous, said Eric Fusil, a submarine expert and associate professor in the University of Adelaide’s School of Electrical and Mechanical Engineering. It would take about “20 milliseconds to crush a hull” at those depths, Fusil said.
Although the Titan’s composite hull is built to withstand intense deep-sea pressures, any defect in its shape or build would compromise its integrity and increase the risk of implosion, said Professor Stefan Williams, a marine robotics and underwater vessel expert at the University of Sydney.

Family member says Pakistani teen was ‘terrified’ of dive
A family member of the two Pakistani passengers killed in the dive says her 19-year-old nephew was hesitant to accompany his father on the voyage.
Azmeh Dawood, the older sister of Shahzada Dawood, told NBC News that her nephew, Suleman, informed a relative that he “wasn’t very up for it” and felt “terrified” about the trip.
She told the outlet that Suleman ended up going on the trip because it fell over Father’s Day weekend and he was eager to please his dad, who was passionate about the Titanic. “I feel disbelief,” Azmeh told NBC. “It’s an unreal situation.”
Suleman was a student at the University of Strathclyde in Glasgow, Scotland, the university confirmed. He just completed his first year in the business school there.
The other three people believed to have perished are Stockton Rush, CEO of OceanGate, British adventurer Hamish Harding and French deep-sea explorer and Titanic expert Paul-Henri Nargeolet.
“Tragic news that those on the Titan submersible, including three British citizens, have been lost following an international search operation,” U.K. Foreign Secretary James Cleverly wrote on Twitter on Thursday. “The UK government is closely supporting the families affected and expresses our deepest condolences.”
Who designed the Titan submersible?
Submersible company OceanGate designed, owned and operated the Titan vessel, according to the company’s website. OceanGate Expeditions, based in the Bahamas, operates the U.S.-based OceanGate Inc., headquartered in Everett, Washington.
The Titan submersible was about 8 feet high, 9 feet wide and 22 feet long, according to the OceanGate website. It was designed to reach about 13,000 feet deep and travel at 3 knots, the company says. The vessel had a five-inch-thick carbon fiber and titanium hull and four 10-horsepower electric thrusters, according to court filings.

OceanGate exaggerated ties to NASA, Boeing in Titan submersible design
Questions were swirling Friday about whether OceanGate may have exaggerated its ties to NASA, Boeing, and the University of Washington in developing its Titan submersible.
“The state-of-the-art vessel, designed and engineered by OceanGate Inc. in collaboration experts from NASA, Boeing and the University of Washington, made its subsea debut in 2018,” OceanGate Expeditions wrote on its website in 2021, according to archived webpages.
In a statement, Boeing said it “was not a partner on the Titan and did not design or build it.”
A spokesperson for NASA told USA TODAY the Marshall Space Flight Center had a “Space Act Agreement” with OceanGate and “consulted on materials and manufacturing processes for the submersible.”
“NASA did not conduct testing and manufacturing via its workforce or facilities, which were done elsewhere by OceanGate,” Lance Davis, Marshall Space Flight Center acting news chief said.
Representatives for the University of Washington did not immediately respond to requests for comment
How many times did OceanGate go to the Titanic?
At least 46 people successfully traveled on OceanGate’s submersible to the Titanic wreck site in 2021 and 2022, according to letters the company filed with a U.S. District Court in Virginia.
“On the first dive to the Titanic, the submersible encountered a battery issue and had to be manually attached to its lifting platform,” one filing says. “In the high sea state, the submersible sustained modest damage to its external components and OceanGate decided to cancel the second mission for repairs and operational enhancements.”
Was the Titan submersible regulated?
When the Titan submersible made its fateful dive into the North Atlantic on Sunday, it also plunged into the murkily regulated waters of deep-sea exploration. It’s a space on the high seas where laws and conventions can be sidestepped by risk-taking entrepreneurs and the wealthy tourists who help fund their dreams. At least for now.
“We’re at a point in submersible operations in deep water that’s kind of akin to where aviation was in the early 20th century,” said Salvatore Mercogliano, a history professor at Campbell University in North Carolina who focuses on maritime history and policy.
Mercogliano said such operations are scrutinized less than the companies that launch people into space. In the Titan’s case, that’s in part because it operated in international waters, far from the reach of many laws of the U.S. or other nations.
The Titan wasn’t registered as a U.S. vessel or with international agencies that regulate safety, Mercogliano said. Nor was it classified by a maritime industry group that sets standards on matters such as hull construction.

James Cameron says passengers may have had ‘warning’ before implosion
Filmmaker and ocean explorer James Cameron, who directed the blockbuster movie “Titanic,” reflected on the eerie parallel between the Titan submersible and the wreck of the Titanic in interviews with multiple news outlets this week.
“The (Titanic) captain was repeatedly warned about ice ahead of his ship, and yet he steamed at full speed into an ice field on a moonless night and many people died as a result,” Cameron told ABC News. “For a very similar tragedy, where warnings went unheeded, to take place at the same exact site with all the diving that’s going on all around the world, I think it’s just astonishing.”
Cameron has embarked on 33 deep-sea dives to visit the Titanic’s wreck site and co-designed a submersible that went to the deepest part of the ocean. He has been vocally critical of the engineering behind the Titan and said he was always concerned it could be too experimental to take passengers to the Titanic wreckage.
He told ABC the five people on the Titan may have had a warning that something was going wrong before the sub imploded. “They probably had warning that their hull was starting to delaminate,” Cameron told the outlet. He said the submersible had sensors on the inside of the hull, “to give them a warning when it was starting to crack.”
Warning system may have given crew little time to react, lawsuit suggests
The Titan sub’s warning system might have given the crew very little time to react, according to court filings by an ex-employee who was sued by OceanGate in 2018.
David Lochridge, a former director of marine operations, was sued over an engineering report he wrote saying the craft under development needed more testing and that passengers might be endangered when it reached “extreme depths.” He claimed he expressed concern that the company was relying on an acoustic monitoring system to “detect the start of a hull break down when the submersible was about to fail.”
“(T)his type of acoustic analysis would only show when a component is about to fail — often milliseconds before an implosion — and would not detect any existing flaws prior to putting pressure onto the hull,” Lochridge contended in a countersuit.
Prior submersible passengers express concerns
Science writer and CBS correspondent David Pogue, who boarded the submersible for a report that aired in November, told USA TODAY he was concerned about the vessel’s safety.
“There were parts of it that seemed to me to be less sophisticated than I was guessing. You drive it with a PlayStation video controller … some of the ballasts are old, rusty construction pipes,” Pogue said. “There were certain things that looked like cut corners.”
Arthur Loibl, a retired businessman from Germany, took a dive to the site two years ago. “Imagine a metal tube a few meters long with a sheet of metal for a floor. You can’t stand. You can’t kneel. Everyone is sitting close to or on top of each other,” Loibl told the Associated Press. “You can’t be claustrophobic.”
During the 2.5-hour descent and ascent, the lights were turned off to conserve energy, he said, with the only illumination coming from a fluorescent glow stick. The dive was repeatedly delayed to fix a problem with the battery and the balancing weights. In total, the voyage took 10.5 hours, he said.
Titanic sub lost at sea documentary receives criticism
A news special on the Titan submersible sparked backlash this week while crews were in the midst of searching for the vessel at sea. ITN’s “Titanic Sub: Lost at Sea” was scheduled to air on Britain’s Channel 5 on Thursday at 2 p.m. ET. Members of the public slammed the program because of its timing.
