Exactly what happened during Titanic five’s final moments, revealed by former Navy doctor 

A decorated former Navy medic has revealed what allegedly happened during the Titanic Five’s tragic final moments before their ship suffered a “catastrophic implosion.”

Dr. Dale Molé, the former director of submarine medicine and radiation health for the US Navy, told DailyMail.com that death would have been quick, painless, almost instantaneous due to the extraordinary forces exerted by the ocean at depth.

Molé said, “It would have been so sudden, they wouldn’t even have known there was a problem, or what had happened to them.

“It’s like you’re here for a minute, and then the switch turns off. One millisecond you’re alive and the next millisecond you’re dead.’

U.S. Coast Guard Rear Admiral John Mauger confirmed at a news conference Thursday that the search for Titan turned up debris “consistent with a catastrophic loss of the pressure chamber.”

Five people were on board, including British billionaire adventurer Hamish Harding and Shahzada Dawood and his son Suleman, who was just 19

The crew was more than 2 miles below the ocean’s surface, which would have generated more than 5,500 pounds per square inch (PSI) of pressure.

Aboard the ship was OceanGate CEO Stockton Rush, 61; French Navy veteran Paul-Henri (PH) Nargeolet, 77; British billionaire Hamish Harding, 58; Pakistani businessman Shahzada Dawood, 41; and his son Suleman, who was just 19.

The small craft and crew were protected by a pressurized chamber, a sealed pod that maintains internal pressure significantly above ambient pressure, a pressurized gas system to control internal pressure, and a supply of breathing gas for the occupants.

Molé said, “The pressure hull is the room where the occupants reside. It sounds like they had bottomed out when the pressure vessel imploded, and usually when it gives way, it gives way all at once.

“It sounds like it was the carbon fiber cylinder that gave way and resulted in the implosion.”

How the pressure chamber was breached remains unclear. But such an implosion could be the result of a leak, a power outage, or a small fire from an electrical short circuit.

What would have resulted would have been a violent and instantaneous implosion as the high pressure water rushed in from the outside, tearing away the tailgate and landing frame and tearing the submarine’s hull apart, crushing the inside.

Molé said, “They would have been ripped to shreds.

“An implosion is when the pressure wave is inward, while an explosion is when the pressure wave or the shock wave goes out from whatever source it is.”

He explained it like overinflating a balloon – the balloon will eventually pop if there is too much pressure.

In an implosion the opposite happens, when there is more external pressure than the container can take, then the inside collapses.

Molé said, “If someone steps on an empty soda can, it would support your weight, but if you then press on the sides, the can will immediately collapse.”

He added, “It’s just where the debris and fragments and everything else go in because of a strong external force. In this case it was the ocean.

“At least at the depth of the Titanic, which is 12,500 feet, the external pressure would be 6,000 lbs per square inch. It is that pressure that, if there were a weakness in the hull, would cause the hull to collapse and suddenly create a shock wave. An implosion can certainly be just as destructive as an explosion.’

According to Scientific Americanif the submarine was near the Titanic, it would have experienced a higher pressure than a great white shark bite.

Nicolai Roterman, a deep-sea ecologist at the University of Portsmouth, UK, agreed that if such an implosion occurred, the pressure would have killed the occupants almost instantly.

“If there were a rupture in the hull, the occupants would succumb to the ocean in an instant.”

The company’s Titan submarine sank about 400 miles southeast of St John’s, Newfoundland, on Sunday morning at 8 a.m. EST, according to the U.S. Coast Guard. It lost contact at 9:45 a.m. but was not reported to the Coast Guard until 5:40 p.m.

Following Thursday’s announcement of the Titanic Five’s death, tributes were posted and released.

Paul-Henri Nargeolet, 77 – commonly known as PH – was part of the first human expedition to visit the Titanic wreck in 1987, having visited the site at least 35 times. His family said their hearts were broken by his death.

“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 everything we know about the ship today, you think of Paul-Henri Nargeolet and his legendary work.

But what we will remember him for most 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.”
