OceanGate submarine disappears at bottom of ocean

The US Navy detected the sound of the explosion of the Titan bathyscaphe using a secret system, the name of which was not mentioned for reasons of national security.

Probably, we are talking about SOSUS (Sound Surveillance Undersea System) — a system of underwater reconnaissance and surveillance, which was used to listen to Soviet submarines:

— it began to be created in 1950, when the United States studied the features of sound propagation over long distances in the oceanic environment;

— in 1953, the first hydrophones and cables were deployed on the continental shelf near the East Coast of the United States, and by 1960, a chain of coastal sonar stations (BGAS) was created. Their location is marked on the map;

— each BGAS consists of antennas, cable routes and coastal data processing posts. With their help, you can receive the noise of submarines and determine their location;

— The United States secretly installed SOSUS cables and acoustic sensors on key sea routes to track the movements of Soviet submarines, wrote Japan's Nihon Keizai;

— according to open sources, the mission was strictly classified throughout the Cold War, it became known only in 1991.

Earlier, the WSJ — after four days of searching for the Titan — wrote that the US military recorded the sound of its explosion on Sunday, around the time when communication was lost with it, but they kept silent about it.

Jack Posobiec, a veteran of US naval intelligence, believes that the Biden administration hid this information in order to give it out later when it would be necessary to divert attention from the case of Hunter Biden, who is accused of corruption. Today, the informants of the case are giving evidence in court.

 
"It has emerged that the US navy had already reported sounds consistent with an implosion on Sunday. It is not clear why this information is only coming to light now."

Also note that there are about 3000 boat migrants that drown each year in the Mediterranean. The media could've easily run stories about those all year long, but they don't. They did have round the clock coverage on this sub though, although it was apparently known since Sunday that the crew died already.
 
There are two ways I could think of that would make such diving attempts much safer:

- Only use proven, heavy duty and reliable submersibles; like the russian ones, as mentioned a couple of posts above

- „Park“ a ship at the spot and permanently attach the submarine with a heave duty cable/chain that is about as long as the depth of the diving. When something goes wrong the ship can pull it up again. And even if the submarine gets stuck in the depths and the ship can‘t pull it up, at least you can find the submarine much quicker.
 
IMO it was a crazy mission, since you are mainly visiting a huge graveyard underwater. As far as I read, one of people had long distance relatives you have been on the Titanic itself.

Nonetheless, it is very sad and I hope that the passengers had a good and quick transition.
 
Cameron says it all. Don't build a submarine with carbon fibre because eventually it will crack.

Indeed. From an engineers perspective it is kind of a nobrainer that you shouldn’t use a material that has a low breaking strength and high predetermined breaking points, or in other words: a material that cracks easily. Instead you would want a material that has high breaking strength that tends not to crack.

PS: And in terms of form you would use a perfect sphere and make the material as thick as possible.

So what was banging on the sea floor?

Banging sounds: The US Coast Guard said it has not identified the source of banging noises that were picked up by sonar Tuesday and Wednesday during the search.


Nothing. They lied about the banging to stall since the sub diversion was being used to distract us from something else.

One must wonder if they did indeed cross into a supernatural void of the unforgiving.
It genuinely was not a place for amateurs or sightseers.


“Today we learned the tragic news about Titan that no one wanted to hear, but that was consistent with the evidence all along: a catastrophic failure of the entire vessel, not just its communication system.

Mercifully, the end came quickly and painlessly for the five precious souls aboard the submersible.

People will naturally wonder if the journey to the Titanic was worth the cost of life. That’s a deep question each person is entitled to answer for themselves. This much is certain: we humans alone are possessed of a mysterious spirit that drives us to abandon the proverbial struggle for survival in order to explore worlds far beyond the Darwinian jungle.

No other animal on the planet has it. We alone are driven to explore the bottom of the deepest ocean, the top of the highest mountain, and the hostile environs of extraterrestrial bodies within and beyond our solar system – all at great peril and cost to ourselves. We alone have traveled to the moon and now speak about going to Mars and then to the stars.

Why? Because of that unique human spirit science alone cannot explain. It’s a spirit at once wondrous and dangerous. A spirit that defines us, that marks us as exceptional among all the marvelous animals on planet Earth.

Rest in peace, you five passengers of the Titan.”Dr. Michael GuillénFormer ABC News Science Editor http://michaelguillen.com

Who knows. It could be anything. It was a very regular pattern, almost mechanical, so I can imagine it was from a ship somewhere. Sound can travel long distances in the water. If it were me, I would play "shave and a haircut" or Wipeout or some other familiar drum pattern or SOS in Morris Code... maybe all three. Something that was unambiguously human.

I agree. And to make suspense. To keep people in front of the news. To give hope when there was no hope. Then when reality comes, to make people more sad. It is a sort of social engineering. It works.
 
Apparently, the implosion killed the crew in milliseconds, which means they didn't suffer. I hope it's at least some consolation to their families and loved ones. The thought of the crew being stuck in the submersible and running out of air must have been terrible to bear.


Death came in “milliseconds” for the five people aboard the doomed Titan submersible, according to experts who spoke after pieces of the vessel that carried its passengers into the depths of the Atlantic to view the Titanic were discovered on the ocean floor.

A remote-operated vehicle (ROV) searching the seabed for the missing submersible found the rear cover of the Titan around 1,600 feet from the Titanic’s bow, Coast Guard Rear Admiral John Mauger said in a news conference. The ROV found more pieces of the submersible, leading authorities to rule that the debris discovered is consistent with “the catastrophic loss of the pressure chamber,” meaning all five aboard the Titan likely died from a massive amount of underwater pressure that killed them instantly.

“A debris field implies a break-up of the submersible … that really sort of indicates what is the worst-case scenario, which is a catastrophic failure and generally that’s an implosion,” marine scientist and rescue expert David Mearns told Sky News.

“The only saving grace is that it would have been immediate — literally in milliseconds — and the men wouldn’t have known what was happening,” Mearns added.

The iconic ship, which sank in 1912, lies some 12,500 feet below the surface, and about 400 miles off the coast of Newfoundland.

The Coast Guard admiral said at the news conference that it would be difficult to locate the bodies because the debris showed that it imploded due to the intense pressure. Mauger added that it was still too early to tell when exactly the vessel imploded, and they will continue conducting remote operations on the sea floor.

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

OceanGate CEO and founder Stockton Rush was piloting the submersible and was joined by billionaire explorer Hamish Harding, British businessman Shahzada Dawood and his son Suleman, and Paul-Henri Nargeolet, an esteemed French maritime expert with decades of experience diving to the Titanic wreckage.

OceanGate released a statement following the Coast Guard’s findings, expressing their sorrow for the loss of life.

“We now believe that our CEO Stockton Rush, Shahzada Dawood and his son Suleman Dawood, Hamish Harding, and Paul-Henri Nargeolet, have sadly been lost,” the statement said.
 
This was not a submarine. I am, personally, ready to go in a Russian submarine to the end of the world! But it has to be Russian. ;-) Because Russians are good in this type of machinery...

Yeah, that’s kinda where I was coming from when I said that looking at the company and the vessel, there’s an argument to be made for them winning the Darwin Award.
