The implosion sound corresponded with the vehicle's descent, the loss of communication, and the loss of navigation.
The odds of those four things happening at the same time and NOT mean the craft went kaput are PowerBall lottery-class.

Over the howling objection of his own party, not the least of which was Harry Truman, JFK made the one and the only tax cut that actually increased government revenue.
And there’s the Eich Bin Berliner speech, and “We choose to go to the moon and the other things, not because they are easy, but because they are hard.”
And when you read of the discussions among his cabinet and even his brother Bobby, if they’d had their way there would have been nuclear war, and all our invasion force would have been incinerated.
I’ve used JFK’s quote many times:
We can always blow up the world,,,,,tomorrow.
And of course we know that a series of waiting until tomorrow to end the world actually saved the world.
Yet the parties themselves have changed over sixty years, and so too has religion.
My father rejoiced he produced milk for children’s school lunches, and my mother believed in school choice, either send your kids to school or go to jail.
And although like all young Christian boys my parents never once paddled me (a custom dating back to Roman times) they surely would have if I’d chosen to refuse to be vaccinated.
The concept of ask not what your country can do for you, but rather what you can do for your country, is strangely liberal and woke today.
I agree with you. But you can't go on odds in that situation. Until it could be proven undoubtedly that the sub imploded or was otherwise sitting on the ocean floor, a surface search was all that could be done, and what had to be done. They couldn't just assume the sub imploded because of a sound, and call off the search. Since an ROV capable of exploring that depth wasn't available until yesterday, all the searchers could do was search the surface in the hopes that something could be found.
It's telling that the ROV found the wreckage within just a few hours. Id wager that everyone involved in the search who knew the Navy's information were sure that the sub imploded, but as I've said, you cant just stop a search on an inconclusive sound, until you find conclusive evidence. You also can't just go out and say, "hey the navy's super secret listening stuff probably heard the thing implode, so we're just out here playing around, the people are probably dead."
As far as the knocking sounds being a "distress signal" or whatever from the sub...that was just people being hopeful, or morbid, depending on their outlook. The Canadians and USCG never said they thought they were distress signals, or anything even related to the sub.
And the adults in charge did the adult thing and didn’t leak that information to the press.
There was a major rescue effort underway, regardless.
The public at large had no need to know of the detection of an implosion until it was verified.
This allowed the maybe a dozen family members of the men who are really the only souls on earth truly grieving today hope right up to the deadline of their oxygen expiring.
And gave the rest of us a good drama to watch.
Too late. But at least we won't realize it for a few more days.
It astounds me the information did not leak.
Whatever threats Admiral Mauger used were effective.
This is going to happen again someday, to some other deep sea exploration.
Admiral Mauger wrote the textbook on how to conduct a rescue operation.
The needed to wait a few days before going to the press so it was the only thing you saw in the news. No point in playing your cards till you really have to.It astounds me the information did not leak.

For sure. I'd bet a lot of the people involved who knew the intelligence were aware of the families of those involved, too, and what leaking that info would mean.It astounds me the information did not leak.

Id have all my money on exactly that. Carbon fiber seems to be great at holding internal pressure, like a gas cylinder...but pretty bad at repeated external pressure, like Titan. Your math is lined up right with what I've heard from various sources.
Even gas cylinders have a hard 15 year life that I mentioned before. Many carbon fiber air bottles fill to 4500 psi, though there are some that go up to 5500. There are established codes for inspecting, maintaining and filling them on top of the hydro 5 year tests and 15 year shelf life.
Cyclic fatigue is a factor in all existing submarines. Here’s a 2000 dated paper on it.
A method for the evaluation of the fatigue operational life of submarine pressure hulls
In this paper, a method is developed to calculate the fatigue lifetime of submarine pressure hulls, applying linear elastic fracture mechanics, based …

Fifty years ago Russia used titanium to build ultra deep diving submarines.
It was phenomenally expensive, and since NATO can torpedo a detected submarine at 3,000 feet nearly as easily as 1000 feet they stopped using titanium.
If money was no object every submersible would probably be made of titanium.
I understand that Titan was made from a titanium shell with carbon fiber spun around it.
Defects in the outer carbon fiber layer might be easily inspected.
But how to inspect the inner shell of titanium, which is notoriously brittle?
Also, the vessel was not stamped out like a unibody automobile. There were welds and a porthole and an escape hatch.
As the little boy said, something’s done gone wrong the wrong way already.
They’ll tell us why, eventually.
That is a point I’m wondering about.
The craft wasn’t designed to be destroyed, but there were four ways to jettison the weights.
The implosion could have jettisoned the weights.
But if they can determine the pressure hull failed after the weights dropped, the pilot knew things had gone very, very wrong.
I believe that the central part of the sub was a five-inch-thick carbon-fiber tube, and that only the fore and aft end-caps were fabricated from titanium.
Thanks.
That certainly means some method to weld all that together.
An implosion could start in the welds, or the caps, or the pressure hull.
Please keep religion and "class" out of this discussion. Well, all of 'em.
Titan sub: OceanGate CEO Stockton Rush admitted 'breaking rules' | Fortune

‘You’re remembered for the rules you break’: OceanGate CEO who was piloting the Titan admitted in 2021 that the sub’s construction had ‘broken some rules’
OceanGate was warned that the Titan, which suffered a “catastrophic implosion” on its journey to see the Titanic shipwreck, had serious design flaws.
This reminded me of my trip to Nepal. When I was flying in that can with propellers, to Lukla airport. It was terrifying, I have never been so scared as I was on those two flights.
