Titanic tourist sub goes missing in Atlantic Ocean, June 2023 #3

RIP
I’m glad it seems this was over instantly - they wont have known

Yes. It appears that it must have occurred around when they got to the sea floor and they died in a moment when they were excited, exploring, and never knew it was over. Maybe they are still in a state thinking they’re traveling/exploring, in the afterlife.

I think there's probably a lot of important or scientific and engineering data that can be gleaned from this crash by analyzing the surviving wreckage.

Just as the NTSB does post-crash investigations which make air travel safer, I hope one good thing to come out of this will be that the knowledge gained will help build better, safer DSVs.

Agreed. We will never stop exploring the ocean. I think this was not close to safe enough for tourists but humans are going to continue to invent, innovate and explore. So we might as well learn all we can. Right?

Titanic submersible live updates: All on board presumed dead after Titan debris is found, Coast Guard says

News on the missing Titanic tourist submersible and the international rescue effort, including updates on the search as the estimated oxygen supply dwindles.

www.nbcnews.com

All five people aboard the Titan submersible are believed to be dead, and debris discovered in the search area for the missing vessel was consistent with a "catastrophic implosion," the U.S. Coast Guard said.

The debris was found off the bow of the sunken Titanic, officials said.

The search for the Titan, which went missing Sunday after embarking on a mission to survey the wreckage of the Titanic, had been focused on an area where Canadian aircraft detected "underwater noises" Tuesday and again yesterday.

U.S. Coast Guard officials had estimated the five passengers could run out of air just before 7:10 a.m. ET today, and the location of the missing vessel had remained a mystery even as the search intensified...

I just hope that it was over in the blink of an eye. My guess is the implosion likely happened 1:45 into the descent which is why communication was cut off. All MOO.

The deep-sea vessel, operated by OceanGate Expeditions, lost contact about an hour and 45 minutes after submerging on Sunday morning with a 96-hour oxygen supply.

And if the implosion would have been "very loud," wouldn't the Mothership have heard it when it happened? Especially if it happened in the mid-depth water column; not at the very bottom?

"Some answers take many forms. There can be truth in all forms"

Faux mysticism aside....

Oceans have constantly changing thermal layers from different water temperatiures and salt levels. These levels can block out alot of sound.

During WWII, U Boats and U boat hunters played a deadly game of hide and seek by moving above, or below these layers. In the cold war, the hide and seek game got very sophisticated regarding what layers do, or do not not radiate sound upwards and what types of sounds radiate good or poorly.

Going back to the Titan....

If the mothership was a US naval support ship with the best listening devices linked to mega sound filtering computers and also having the ability to "dip" listening devices below thermal layers when needed, my bet is that they would have heard something.

But....

If the mothership is a regular ship using high quality commercial, but not military grade listening devices, I am thinking "Maybe, maybe not" in regards to hearing something.

Ok. Goodbye.
I feel sad as he!! but there we go. Would have happened quickly is my guess, my thoughts are with everyone but mainly the dad and son. Rest in peace all of you, I don't think the Titanic community will be what it was for a long time

 

[gitana1]

They just said the son did not want to go in the sub, but did it because it was Father’s Day. That is awful. OMG

Oh no. I hope that’s not true.

 

[gitana1]

This James Cameron (Titanic movie director) statement from 2018 is something to think about (imo)...


“I call it bearing witness. I get to bear witness to a miracle that’s down there all the time,” Cameron told 60 Minutes Australia in 2018 of his deep-sea explorations. “This is not just some, you know rich guy ego thing. This is about, you’ve got so much time on this planet, so much life, so much breath in your body. You have to do something. If you should be fortunate enough to make some money and have some capital, some working capital, why not put it into your dream.”

How did he get down there?

 

[Twistinginthewind]

This is so incredibly sad to learn all 5 souls on board are lost. I hope they were elated they were so close to the wreck and no suffering occurred. RIP all 5 of you, and heartfelt globally shared condolences to your families, cowokers, colleagues, friends and communities.

He's done a lot in other vessels... he went even deeper in this... @Interested_But_Confused posted about it.

Azmeh claimed that her nephew did not want to go on the submarine but agreed to take part in the expedition because it was important to his father, a lifelong Titanic obsessive. Suleman "wasn't very up for it" and "terrified," she claimed, explaining that the 19-year-old expressed his concerns to another family member.

Wouldn’t he be prevented from going if the people involved detected he was terrified? I mean the people who go are super motivated to be there. Wouldn’t it be obvious if he wasn’t? Ugh. Poor kid.

I’d like to learn about those other vessels. I really didn’t understand much of anything about this prior to this tragedy.

 

[MsMarple]

It's been said in many articles that the Titan only knew such things through communication with the surface crew. That's why the loss of communication was so dire, even if the sub was intact. It had no means to navigate itself.

MOO

I managed to find the information. It had 4 electric thrusters and a sonar navigation system.

* Titan weighs 9,525 kg (21,000 lbs), and can travel at a speed of 3 knots (3-1/2 miles per hour) using electric thrusters. OceanGate says it is equipped with powerful LED lights, a sonar navigation system and high-end camera equipment. It has a single porthole.

What is the OceanGate Titan submersible and how does it work?

The owner of the submersible that went missing during a tourist expedition to the Titanic's wreckage said on Thursday it believed that the crew on board have "sadly been lost" after debris matching the missing sub was found on the ocean floor.

How did he get down there?

I know he designed and built a submersible.


Here's an article from 2012

Mr Cameron has spent the past few years working in secret with his team of engineers to design and build the craft, which weighs 11 tonnes and is more than 7m (23ft) long.
He describes it as a "vertical torpedo" that slices through the water allowing him a speedy descent.

Debris found on ocean floor has been assessed to be from the external body of the Titan sub​

From CNN's Priscilla Alvarez

The debris discovered within the search area of the missing Titanic submersible has been assessed to be from the external body of the sub, according to a memo reviewed by CNN.

The search for the crew capsule of the Titan vessel continues, the memo says.

The debris was located on the ocean floor, roughly 500 meters (about a third of a mile) off of the bow of the Titanic, and it was found around 8:55 a.m. ET.

I do not know much about subs or pressure, but have any of the experts or people on here said if the passengers would have been aware that they were about to face a catastrophic failure moments before the implosion? And if the implosion would have been "very loud," wouldn't the Mothership have heard it when it happened? Especially if it happened in the mid-depth water column; not at the very bottom?

I don't think there is really any way to know if they would have been aware that an implosion was coming. Could there have been sounds/noises indicating that something was wrong in the moments before? Who knows. I would think if there was it would have been only moments before. Once the structure began to fail, due to the immense pressure, it would not have been gradual but almost instantaneous.

As for the sound of the implosion, it wouldn't have been audible to the human ear on the ship. The communications folks would have been listening for a specific sound, but may have heard a thump or something. The ocean is a noise place really

Deeply sad, deeply tragic, but hopefully as others have said here, their lives were lost in an instant, filled with awe and wonder as they marveled at the sight of the mother ship.

It's time to move on from this one. More than many cases here, I've found this a difficult one to process and rationalise. At least now their loved ones have some form of closure.

I am hopeful too, that our society, governments and organisations will learn from this at some point.

“People in the community were very concerned about this sub,” Cameron said. “A number of the top players in the in the deep submergence engineering community even wrote letters to the company, saying that what they were doing was too experimental to carry passengers and that it needed to be certified. 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. For us, it’s 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. It’s really quite surreal.”

“PH, the French legendary submersible dive pilot was a friend of mine,” Cameron said. “You know, it’s a very small community. I’ve known PH for 25 years, and for him to have died tragically in this way is almost impossible for me to process.”

Cold comfort, but I think the fact that they weren't trapped down there for days, alive, with him enduring it when he didn't want to go at all makes it less awful than it could have been. The hull failure would have been so fast none of them would have known about it.

MOO

Do we know they were trapped down there for days, alive? I was under the impression the implosion happened when they reached the depth of the Titanic.
