Missing Titanic Submersible: ‘Catastrophic Implosion’ Likely Killed 5 Aboard Submersible (2024)

Pinned

After days of searching, no hope of finding survivors remains. Here’s the latest.

However, the revelation is likely to raise further questions about a vast, multinational dayslong search and rescue effort that has ended in failure.

Those presumed lost onboard were Stockton Rush, the chief executive of OceanGate, the company that operated the submersible, who was piloting. The four passengers were a British businessman and explorer, Hamish Harding; a British-Pakistani businessman, Shahzada Dawood, and his teenage son, Suleman; and a French maritime expert, Paul-Henri Nargeolet, who had been on over 35 dives to the Titanic wreck site. (Read more about the lives that were lost.)

Here’s what else to know:

• A remote-controlled vehicle had located the debris from the Titan, including the submersible’s tail cone, about 1,600 feet from the bow of the Titanic on the ocean floor, according to Admiral Mauger.

• Leaders in the submersible craft industry warned for years of possible “catastrophic” problems with the vehicle’s design. They also worried that OceanGate Expeditions had not followed standard certification procedures.

• OceanGate has provided tours of the Titanic wreck since 2021 — for a price of up to $250,000 per person — as part of a booming high-risk travel industry. The company has described the trip on its website as a “thrilling and unique travel experience.”

• The Titan squeezed five passengers into a tight space with no seats, only a flat floor and a single view port 21 inches in diameter. Here’s a closer look at the craft.

Secret Navy sensors detected a possible implosion around the time the Titan’s communications failed.

The data from the sensors was combined with information from airborne Navy P-8 surveillance planes and sonar buoys on the surface to triangulate the approximate location of the Titan, one of the officials said. The analysis of undersea acoustic data and information about the location of the noise were then passed on to the Coast Guard official in charge of the search, Rear Adm. John Mauger.

Because there was no visual or other conclusive evidence of a catastrophic failure, one of the officials said, it would have been “irresponsible” to immediately assume the five passengers were dead, and the search was ordered to continue even though the outlook appeared grim. Both of the Navy officials spoke on the condition of anonymity to discuss operational details.

It was not immediately clear how widely the Navy’s acoustical analysis was disseminated among the search team, nor why the Navy had not made it public earlier. The Navy’s acoustic analysis from the secret sensor network was first reported by The Wall Street Journal.

The director and deep-sea explorer James Cameron points to flaws in the Titan submersible’s design.

In an interview, Mr. Cameron called the presumed loss of five lives aboard the Titan submersible from the company OceanGate like nothing anyone involved in private ocean exploration had ever seen.

“There’ve never been fatalities at this kind of depth and certainly no implosions,” he said.

An implosion in the deep sea happens when the crushing pressures of the abyss cause a hollow object to collapse violently inward. If the object is big enough to hold five people, Mr. Cameron said in an interview, “it’s going to be an extremely violent event — like 10 cases of dynamite going off.”

In 2012, Mr. Cameron designed and piloted an experimental submersible into a region in the Pacific Ocean called the Challenger Deep. Mr. Cameron had not sought certification of the vessel’s safety by organizations in the maritime industry that provide such services to numerous companies.

“We did that knowingly” because the craft was experimental and its mission scientific, Mr. Cameron said. “I would never design a vehicle to take passengers and not have it certified.”

Mr. Cameron strongly criticized Stockton Rush, the OceanGate chief executive who piloted the submersible when it disappeared Sunday, for never getting his tourist submersible certified as safe. He noted that Mr. Rush called certification an impediment to innovation.

“I agree in principle,” Mr. Cameron said. “But you can’t take that stance when you’re putting paying customers into your submersible — when you have innocent guests who trust you and your statements” about vehicle safety.

As a design weakness in the Titan submersible and a possible cautionary sign to its passengers, Mr. Cameron cited its construction with carbon-fiber composites. The materials are used widely in the aerospace industry because they weigh much less than steel or aluminum, yet pound for pound are stronger and stiffer.

The problem, Mr. Cameron said, is that a carbon-fiber composite has “no strength in compression”— which happens as an undersea vehicle plunges ever deeper into the abyss and faces soaring increases in water pressure. “It’s not what it’s designed for.”

The company, he added, used sensors in the hull of the Titan to assess the status of the carbon-fiber composite hull. In its promotional material, OceanGate pointed to the sensors as an innovative feature for “hull health monitoring.” Early this year, an academic expert described the system as providing the pilot “with enough time to arrest the descent and safely return to surface.”

In contrast to the company, Mr. Cameron called it “a warning system” to let the submersible’s pilot know if “the hull is getting ready to implode.”

Mr. Cameron said the sensor network on the sub’s hull was an inadequate solution to a design he saw as intrinsically flawed.

“It’s not like a light coming on when the oil in your car is low,” he said of the network of hull sensors. “This is different.”

Shahzada Dawood, Executive, 48, and Son, 19, Die Aboard Submersible

Mr. Dawood was the vice chairman of Engro Corporation, a business conglomerate headquartered in the Pakistani port city of Karachi that is involved in agriculture, energy and telecommunications. His family is known as one of the wealthiest business families in the country.

His work focused on renewable energy and technology, according to a statement from his family.

Mr. Dawood was born on Feb. 12, 1975, in Rawalpindi, Pakistan. He studied law as an undergraduate at Buckingham University in Britain and later received a master’s degree in global textile marketing from Philadelphia University, now part of Thomas Jefferson University. In 2012, he was named a Young Global Leader by the World Economic Forum.

His son was a business student at the University of Strathclyde in Glasgow and had just completed his first year, a spokesman for the school said. Like his father, he was a fan of science fiction and enjoyed solving Rubik’s Cubes and playing volleyball, according to a statement from Engro.

“The relationship between Shahzada and Suleman was a joy to behold; they were each other’s greatest supporters and cherished a shared passion for adventure and exploration of all the world had to offer them,” the family’s statement said.

The pair’s shared passion for science and discovery, friends and family said, led them to embark on the expedition to the wreck of the Titanic.

Travel and science were “part of his DNA,” said Ahsen Uddin Syed, a friend of the elder Mr. Dawood who used to work with him at Engro.

A lover of “Star Trek” and “Star Wars,” Mr. Dawood was also fond of nature and often traveled to faraway places and shared pictures of his adventures, Mr. Sayed said.

His Instagram profile is like a memory book of his love of travel and nature; it is blanketed with photos of birds, flowers and landscapes, including a sunset in the Kalahari Desert, the ice sheet in Greenland, penguins in the Shetlands and a tiny bird in London with the caption “Dance of the Sugar Plum Fairy.”

“Don’t adventures ever have an end?” Mr. Dawood wrote in a Facebook post last year from a trip to Iceland, quoting Bilbo Baggins from “The Fellowship of the Ring.” “I suppose not. Someone else always has to carry on the story.”

Khalid Mansoor, another former colleague of Mr. Dawood’s, said that Mr. Dawood was a passionate champion of the environment. He was also a trustee at the SETI Institute, an organization devoted to the search for extraterrestrial intelligence.

In his role at Engro, the company statement said, Mr. Dawood advocated “a culture of learning, sustainability and diversity.” He was also involved in his family’s charitable ventures, including the Engro Foundation, which supports small-scale farmers, and the Dawood Foundation, an education-focused nonprofit.

“Shahzada’s and Suleman’s absence will be felt deeply by all those who had the privilege of knowing this pair,” his family’s statement read.

Mr. Dawood is survived by a daughter, Alina, and his wife, Christine.

Stockton Rush, Pilot of the Titan Submersible, Dies at 61

Mr. Rush first looked skyward for adventure. In 1981, when he was 19, he was believed to be the world’s youngest jet-transport-rated pilot.

If the sky was the limit, though, it was too confining for Mr. Rush.

“I wanted to be the first person on Mars,” he told Fast Company magazine in 2017.

Ineligible for Air Force pilot training because of poor eyesight, he said, he abandoned his dream of becoming an astronaut. Interplanetary travel didn’t seem economically viable in the foreseeable future. But he saw potential in underwater travel, and he said he was willing to take on risk and bend the rules to achieve his goals.

“I mean, if you just want to be safe, don’t get out of bed,” he said in an interview with “CBS News Sunday Morning” last year. “Don’t get in your car. Don’t do anything. At some point, you’re going to take some risk, and it really is a risk-reward question. I think I can do this just as safely by breaking the rules.”

Richard Stockton Rush III was the scion of one of San Francisco’s most famous families. He was descended on his father’s side from two signers of the Declaration of Independence, Benjamin Rush and Richard Stockton.

He was born on March 31, 1962, in San Francisco. His father is chairman of the Peregrine Oil and Gas Company in Burlingame, Calif., and the Natoma Company, which manages apartment and other investment properties in and around Sacramento. His grandfather was the chairman of the shipping company American President Lines. Louise M. Davies Symphony Hall in San Francisco was named for his grandmother.

The Davies family’s inherited wealth was derived from Ralph K. Davies, who began at Standard Oil of California as a 15-year-old office boy and rose to become the youngest director in the company’s history.

Stockton, as Mr. Rush was known, graduated from Phillips Exeter Academy in New Hampshire and earned a Bachelor of Science degree in aerospace engineering from Princeton University in 1984. He received a Master of Business Administration degree from the University of California, Berkeley, Haas School of Business in 1989.

During summer breaks, he served as a DC-8 first officer, flying out of Jeddah, Saudi Arabia, for Overseas National Airways. The year he graduated, he joined the McDonnell Douglas Corporation as a flight test engineer on the F-15 program and was named the company’s representative at Edwards Air Force Base on the APG-63 radar test protocol.

Before founding OceanGate, he served on the board of BlueView Technologies, a sonar developer in Seattle, and as chairman of Remote Control Technologies, which makes remotely operated devices. He was also a trustee of the Museum of Flight in Seattle from 2003 to 2007.

In 1986, he married Wendy Hollings Weil, a licensed pilot, substitute teacher and account manager for magazine publishing consultants. She became the director of communications for OceanGate.

Her grandfather, Richard Weil Jr., was president of Macy’s New York, and she was the great-great-granddaughter of the retailing magnate Isidor Straus and his wife, Ida, two of the wealthiest people to die when the Titanic sank.

The aging Mr. Straus, a co-owner of Macy’s, refused to board the lifeboat while younger men were being prevented from boarding. Ida Straus, his wife of four decades, declared that she would not leave her husband, and the two were seen standing arm in arm on the Titanic’s deck as the ship went down.

Information on Mr. Rush’s survivors was not immediately available.

In his CBS News interview, Mr. Rush acknowledged that it was prudent while exploring the ocean at depths of thousands of feet to avoid fish nets, overhangs and other hazards. But, he said, safety concerns could also be a drag on a swashbuckling career in which risk paid returns not only in profits but also in unforgettable experiences.

“It really is a life-changing experience, and there aren’t a lot of things like that,” he told Fast Company. “Rather than spend $65,000 to climb Mount Everest, maybe die, and spend a month living in a miserable base camp, you can change your life in a week.”

His trips in the Titan brought him the adventure he craved.

“I wanted to be sort of the Captain Kirk,” he said. “I didn’t want to be the passenger in the back. And I realized that the ocean is the universe. That’s where life is.”

The Coast Guard says it found five major pieces of debris on the ocean floor.

The debris was “consistent with catastrophic loss of the pressure chamber” of the submersible, he added.

Asked about the possibility of recovering the bodies of the victims, Admiral Mauger said that he did not have an answer. “This is an incredibly unforgiving environment down there on the sea floor,” he said.

Chances for the survival of the five passengers had begun to look grim by midweek, but rescuers had said that they were holding out hope that the Titan could be out there somewhere.

But on Thursday morning, a remotely operated vehicle discovered a debris field on the ocean bottom. Paul Hankins, a salvage expert for the U.S. Navy, said there were “five major pieces” that appeared to be parts of the Titan, a 22-foot-long vessel owned by OceanGate, including a nose cone, the front end of the pressure hull and the back end of the pressure hull.

It was too early to tell exactly when the vessel imploded, Admiral Mauger said. The implosion “would have generated significant broadband sound down there that the sonar buoys would have picked up,” he added, but listening devices in the area did not hear any signs of such a catastrophic failure.

Some underwater banging noises were picked up by searchers earlier this week, but they did not appear to have had any relation to the submersible, Admiral Mauger said. Previously, the Coast Guard had said that they repositioned their search efforts around where those noises were detected.

“I know there’s a lot of questions about how, why, when this happened,” Admiral Mauger said, adding that the authorities had those same questions. “That’s going to be, I’m sure, the focus of future review,” he said. “Right now, we’re focused on documenting the scene.”

Hamish Harding, an Explorer Who Knew No Bounds, Dies at 58

Mr. Harding was 58.

Passengers had paid up to $250,000 each for the privilege of plunging nearly 13,000 feet below the surface for a glimpse of the remains of history’s most storied oceanic tragedy. The R.M.S. Titanic hit an iceberg and sank in 1912, four days into its maiden voyage, about 400 miles off Newfoundland. More than 1,500 people died.

At the outset of the tour, Mr. Harding saw the opportunity as an unlikely stroke of good fortune. “Due to the worst winter in Newfoundland in 40 years,” he wrote in a social media post on Saturday, “this mission is likely to be the first and only manned mission to the Titanic in 2023.”

He described himself as a “mission specialist” on the expedition.

Mr. Harding seemed to presage his own fate in a 2021 interview after a record-setting plunge to Challenger Deep, the deepest part of the ocean in the Mariana Trench.

At nearly 36,000 feet below the western Pacific Ocean, deeper than Mount Everest is tall, that four-hour, 15-minute voyage took him nearly three times further down than the Titanic site. That expedition, with the American explorer Victor Vescovo, earned two citations by Guinness World Records, for the longest distance traversed at full ocean depth by a crewed vessel and the longest time spent there on a single dive.

As Esquire Middle East magazine pointed out at the time, only 18 people had ever journeyed to the bottom of the Challenger Deep, as opposed to the 24 astronauts who had orbited or landed on the moon and the thousands who successfully had scaled the peak of Mount Everest.

Mr. Harding knew the risks. “If something goes wrong, you are not coming back,” he told The Week, an Indian newsmagazine. But in business, and in his life of adventure seeking, he seemed to embrace them.

A pilot licensed to fly both business jets and airliners, Mr. Harding started the first regular business jet service to the Antarctic in 2017, in partnership with the luxury Antarctic tourism company White Desert. The service landed its first flight, a Gulfstream G550, on a new ice runway known as Wolf’s Fang.

A lifelong space buff, he traveled to Antarctica in 2016 with Buzz Aldrin, the Apollo 11 astronaut and the second man to walk on the moon. At 86, Mr. Aldrin became the oldest person to reach the South Pole. Four years later, Mr. Harding took a similar journey with his son Giles, who at 12 became the youngest person to accomplish that feat.

In 2019, Mr. Harding set off on another record-setting venture with a former astronaut when he and the former International Space Station commander Col. Terry Virts completed the fastest circumnavigation of the world over both the North and South Poles in a Qatar Executive Gulfstream G650ER long-range business jet.

In June 2022, Mr. Harding finally got to experience the wonder of being an astronaut himself, soaring some 60 miles aboard the New Shepard spacecraft, from Jeff Bezos’s Blue Origin space tourism company, to the edge of outer space.

“Once the liquid hydrogen/oxygen booster rocket gets the capsule to the edge of space, 350,000 feet above the earth,” he said in an interview last year with Business Aviation Magazine, “the sky above you is totally, completely black, even right next to the sun.”

Despite a life of dramatic quests that seemed drawn from boys’ adventure books, Mr. Harding was by nature “an explorer, not a thrill seeker,” Colonel Virts said in an interview with the BBC.

Mr. Harding apparently agreed. In discussing the Challenger Deep mission, he emphasized science, not derring-do.

“As an explorer and adventurer, I want this expedition to contribute to our shared knowledge and understanding of planet earth,” he said in the Esquire interview. He spoke of collecting samples from the ocean floor “that could contain new life forms and may even provide further insights into how life on our planet began.”

“And in searching for signs of human pollution in this remote environment,” he continued, “we hope to aid scientific efforts to protect our oceans and ensure they flourish for millennia to come.”

George Hamish Livingston Harding was born on June 24, 1964, in Hammersmith, London.

He was always drawn to the skies, and beyond. “I was 5 years old when the Apollo landing took place,” he said in the Business Aviation interview. “I vividly remember watching the event on an old black-and-white TV set with my parents in Hong Kong, where I grew up.”

“This event set the tone of my life in a way,” he continued. “We sort of felt that anything was possible after that, and we fully expected there to be package holidays to the moon by now.”

At 13, he became a cadet in the Royal Air Force flying Chipmunk trainer airplanes. He earned his pilot’s license in 1985 while an undergraduate at the University of Cambridge, where he studied chemical engineering and natural sciences.

In the 1990s, he built a career in information technology, rising to managing director of Logica India, a company based in Bangalore. He used the money he made in that industry to found Action Group, a private investment company, in 1999. He started Action Aviation in 2002.

His survivors include his wife, Linda; his sons, Rory and Giles; a stepdaughter, Lauren Marisa Szasz; and a stepson, Brian Szasz.

In the Business Aviation interview, Mr. Harding said that the Titanic dive, initially scheduled for last June, had been delayed because “the submersible was unfortunately damaged on its previous dive.” Instead, that summer he climbed Mount Kilimanjaro in Tanzania with 20 family members and friends.

When asked about the risks of his boundary-pushing ventures, Mr. Harding, who was the chairman of the Middle East chapter of the Explorers Club, said, “My view is that these are all calculated risks and are well understood before we start.”

“I should add that I do not go out seeking these opportunities,” he continued. “People tend to bring them to me, and I keep saying ‘Yes!’”

Here is why the U.S. Coast Guard led the search effort.

Most Americans are familiar with Coast Guard operations closer to home — from interdicting drug smugglers to assisting recreational boaters — but the maritime force has long been dedicated to search and rescue efforts at sea, including those in international waters.

For the past week, the Coast Guard oversaw an armada of vessels, aircraft and specialists from North America and Europe to find the Titan. International agreements divide the ocean into regions and offer guidance about which nations and agencies take primary responsibility for search and rescue in each. The site of the Titanic wreck is in an area generally assigned to the Coast Guard, even though it is closer to the coast of Newfoundland, Canada, than that of the continental United States.

Beyond that, the U.S. Coast Guard is considered “the premier maritime search and rescue agency in the world,” said Aaron C. Davenport, a senior researcher at the Rand Corporation and 34-year veteran of the service.

Chris Boyer, the executive director of the National Association for Search and Rescue, a nonprofit advocacy group, called the Coast Guard “the best prepared and the best choice, given the circ*mstances.” He added that while the United States Navy also had underwater rescue capabilities and was participating in the search, it was more focused on defense than on this type of mission.

The disappearance of the Titan, which vanished while descending to view the wreck of the Titanic, presented a unique challenge. The small, privately owned vessel was sealed shut from the outside, and rescuing people from it far below the surface would have been very difficult, Mr. Boyer said.

The Coast Guard handles thousands of rescues every year, but many are comparatively straightforward, like finding a lost fishing boat, according to Robert B. Murrett, aretired Navy vice admiralwho is now deputy director of theSyracuse University Institute for Security Policy and Law.

“This one’s a little bit different because of the water depth involved, and the nature of the vehicle,” Professor Murrett said.

Even so, he said, the Coast Guard is adept at coordinating search efforts involving different agencies from different countries.

The search for the Titan was “an incredibly complex operation,” Rear Adm. John Mauger, a Boston-based Coast Guard commander, told reporters on Thursday.

“We were able to mobilize an immense amount of gear to the site in just a really remarkable amount of time, given the fact that we started without any sort of vessel response plan for this or any sort of pre-staged resources,” he said.

OceanGate was warned of potential for ‘catastrophic’ problems with its Titanic mission.

OceanGate’s director of marine operations, David Lochridge, started working on a report around that time, according to court documents, ultimately producing a scathing document in which he said the craft needed more testing and stressed “the potential dangers to passengers of the Titan as the submersible reached extreme depths.”

Two months later, OceanGate faced similarly dire calls from more than three dozen people — industry leaders, deep-sea explorers and oceanographers — who warned in a letter to its chief executive, Stockton Rush, that the company’s “experimental” approach and its decision to forgo a traditional assessment could lead to potentially “catastrophic” problems with the Titanic mission.

A spokesman for OceanGate declined to comment on the five-year-old critiques from Mr. Lochridge and the industry leaders. Nor did Mr. Lochridge respond to a request for comment.

The Coast Guard said it would hold a news conference at 3 p..m. Eastern time in Boston to address findings from a remote-operated vehicle deployed by the Canadian vessel Horizon Arctic on the sea floor near the Titanic.

Another remotely controlled deep-sea vehicle is en route to the search area.

Magellan’s vehicle has been to the wreckage of the Titanic — which sits at a depth of about 12,500 feet — more than any other vehicle and has mapped the site, including the surrounding debris, Richard Garriott de Cayeux, president of the Explorers Club, said in a statement. It has manipulator arms that can attach lifting cables directly to a submersible, and “may prove invaluable” to the ongoing search and rescue efforts, Mr. Garriott de Cayeux said. Magellan did not respond to a request for comment.

Mr. Garriott de Cayeux said that other club members with experience diving to similar depths had a sense of what the passengers on the Titan may be facing.

“While the planned life support supply depletes, we believe crew conservation and the near freezing temperatures could prolong life support by some time and the crew knows this,” he said in the statement.

“While the situation is very difficult, we can all be grateful and hopeful as the very best people are on the job,” Mr. Garriott de Cayeux said.

“We are deeply concerned about Suleman, his father and the others involved in this incident,” the spokesman said. “Our thoughts are with their families and loved ones and we continue to hope for a positive outcome.”

Photos from an early test of the Titan show how the submersible is deployed.

The Titan’s lighter weight and launch and recovery platform would make it “a more financially viable option for individuals interested in exploring the deep,” the company said in a 2018 news release.

But even before the April 2018 saltwater test, experts inside and outside the company had begun warning of potentially “catastrophic” problems that could result from what they said was the company’s “experimental” approach.
