Search Day 4: Titan submersible debris found, all onboard presumed dead

Tech journalist and “CBS Sunday Morning” correspondent David Pogue, who observed an OceanGate Expeditions Titanic shipwreck trip last year, the last before the Titan disappeared this week, said a “massive amount of misinformation” has circulated online this week.

In an interview, Pogue, whose coverage of the submersible last year has attracted renewed interest in light of the disaster, also responded to attacks on his reporting over the past two days.

Critics on Twitter have suggested that Pogue and other journalists undersold how dangerous the submersible was or even that he conspired to shield the company from accountability. 

Pogue countered that the safety issues were the “centerpiece” of his OceanGate coverage. “There is a fundamental lack of understanding of the deep-sea diving industry process,” he said.

Paul-Henri Nargeolet, a French diver and Navy veteran who died aboard the Titan, was “fearless” and understood the potential danger of traveling to the Titanic's wreckage, his stepson said in an interview.

"Anyone who gets into those submersibles knows the risks that could happen," stepson John Paschall said, adding: "Going into this, he knew the risks that were possible with this expedition."

Paschall described Nargeolet, who had led several expeditions to the sunken passenger ship and supervised the recovery of at least 5,000 artifacts, as “the world expert on the Titanic.”

The ocean, Paschall said, was Nargeolet’s “home away from home. He was just so comfortable out there and in any ocean and any lake or whatever it was. The water was just so connected to him.”

“And that especially goes for the Titanic,” Paschall said. “He put so much of his life into that ship.”

Paschall also recalled Nargeolet as a “really incredible stepfather” — someone who was respectful, loving and funny. 

While Nargeolet knew the risks of traveling in a submersible, Paschall said, he wanted to know more about how the company that operated the boat, OceanGate, had maintained the vessel and whether it had kept passengers properly informed.

“Were all the safety procedures followed as closely as possible?” Paschall said. “Was everyone aware of everything that was going on? Was there anything that was missed during any kind of inspection?”

In the days before the Titan vessel went into the ocean off Newfoundland, Canada, the 19-year-old university student accompanying his father on the expedition expressed hesitation about going, his aunt said in an interview Thursday.

Azmeh Dawood — the older sister of Pakistani businessman Shahzada Dawood — said her nephew, Suleman, informed a relative that he “wasn’t very up for it” and felt “terrified” about the trip to explore the wreckage of the Titanic.

But he ended up going aboard OceanGate’s 22-foot submersible because the trip fell over Father’s Day weekend and he was eager to please his dad, who was passionate about the lore of the Titanic, Azmeh Dawood said.

The family of French dive expert Paul-Henri Nargeolet say they will remember him for the rest of their lives after he and four other people died in the Titan submersible accident.

Nargeolet was an “extraordinary father and husband,” the family said.

"He is a man who will be remembered as one of the greatest deep-sea explorers in modern history. When you think of the Titanic and all we know about the ship today, you will think of Paul-Henri Nargeolet and his legendary work," they said in a statement.

The statement added: "But what we will remember him most for is his big heart, his incredible sense of humor and how much he loved his family. We will miss him today and every day for the rest of our lives."

Nargeolet led several expeditions to the Titanic wreckage site, completing at least 35 dives in submersibles and supervising the recovery of at least 5,000 artifacts, including the recovery of the "big piece" — a 20-ton section of the Titanic’s hull — according to Experiential Media Group, where he was the director of underwater research.

The family thanked everyone involved in the dayslong rescue effort and extended condolences to the families of the others who died.

The family of British billionaire Hamish Harding and his company are “united in grief” with the families of four other people all dead in the Titan submersible incident, Action Aviation said in a statement.

“Hamish Harding was a loving husband to his wife and a dedicated father to his two sons, whom he loved deeply. To his team in Action Aviation, he was a guide, an inspiration, a support, and a Living Legend,” the company said.

Harding, a former pilot and explorer, was inducted as a Living Legend of Aviation last year, Action Aviation said.

The family of the father and son who died in the Titan submersible are asking for prayers and said they found strength in rescue efforts.

Pakistani businessman Shahzada Dawood and his son, Suleman, were among the five people killed on the submersible that imploded.

“It is with profound grief that we announce the passing of Shahzada and Suleman Dawood," the family said in a statement released by the Dawood Foundation. "Our beloved sons were aboard OceanGate’s Titan submersible that perished underwater. Please continue to keep the departed souls and our family in your prayers during this difficult period of mourning.”

The family said they were grateful to the people involved in the rescue efforts, saying that "their untiring efforts were a source of strength for us during this time."

"We are also indebted to our friends, family, colleagues, and well-wishers from all over the world who have stood by us during our hour of need," the statement said. "The immense love and support we receive continues to help us to endure this unimaginable loss.”

The Dawood family also offered condolences to the families of the other people aboard the Titan.

A U.S. Navy analysis of acoustic data “detected an anomaly consistent with an implosion or explosion” near the Titan around the time it lost communications, a senior Navy official said.

The sound consistent with an implosion was heard Sunday, shortly after the submersible lost communications, the official said.

The sound was not definitive, the official said, and it was immediately shared with commanders, who decided to continue searching.

“This information was considered with the compilation of additional acoustic data provided by other partners and the decision was made to continue our mission as a search and rescue and make every effort to save the lives on board,” the Navy official said.

The Wall Street Journal first reported that the sound had been detected.

“Titanic” director James Cameron said he was astonished by the similarities between the ship that sank in 1912 and the Titan submersible that imploded with five people aboard.

“I’m struck by the similarity of the Titanic disaster itself, where the 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 said in an interview with ABC News.

“For a very similar tragedy, where warning signs went unheeded, to take place at the same exact site, with all the diving that’s going on all around the world … it’s just astonishing,” he added. “It’s really quite surreal.”

Cameron said submersible diving is a “mature art” and noted many people in the deep submergence engineering community wrote letters to OceanGate Expeditions, the company behind the mission, pleading that what the company was doing was “too experimental to carry passengers.”

The movie director said one of the passengers aboard the Titan, French dive expert Paul Henry Nargeolet, whom he called “PH,” was a friend he had known for 25 years. He said Nargeolet’s death “is almost impossible for me to process.”

Cameron said he's made 33 dives to the Titanic wreckage site and calculated he's “spent more time on the ship than the captain did back in the day.”

Cameron’s 1997 film starring Leonardo DiCaprio and Kate Winslet is among the highest-grossing movies of all time, raking in more than $2 billion.
