Titan sub noise heard on board support ship.

[LittleInch]

Just watched a new documentary by the BBC and others like Discovery so if you're interested look out for it. Implosion: The titanic sub disaster.

Key new part for me is that they released video of the moment a loud "crump" was actually heard on board the support vessel apparently through the hull with Rushs wife Wendy doing the monitoring of the sub and her saying "what was that?". They then got a message from the sub which must have been somehow delayed saying dropped two weights which confused them. It is pretty chilling to listen to alright. That and the fact that they were thought not to be at the ocean floor implies they were getting some warnings.

This is a clip but there are others.

Not much we didn't already know, but they have noted dive 81 (out of 88) where there was a very large bang heard which they reckon was the point at which the hull was on its last legs after a major internal failure.

The Discovery documentary maker back in 2022 was very unimpressed with the whole thing and persuaded the company to can their documentary as he was convinced it would end in failure and didn't want to be seen to promote the operation.

Looks like it's on Discovery pretty soon. If you're interested, it's pretty good and not that big into the human interest side, but does have input from the wife of the man and his son that died which is quite moving.

Multiple engineers had singled the issue out and documented the urgent danger in writing, specifically warning about the risk posed by cold temperatures on the day of launch. And just like Stockton Rush, NASA’s program managers ignored those warnings, shut the door, and pressed ahead anyway.

The decision wasn't NASA's, McDonald claimed that he refused to signoff on the launch and that Thiokol execs overruled him.

His claim doesnt pass the sniff test tho, nor do others he's made. He was the Chief Engineer for a mega-corp, a 27-year employee, physically at Cape Canaveral for the launch, surrounded by VIPs and reporters, and purportedly predicted a disaster based on a few non-catastrophic failures during the little testing conducted........yet he didnt say/do anything memorable to stop the launch. If true, he had little regard for human life. The other possibility is that he didnt think the risk was particularly great. Also noteworthy is that he spent years spouting conspiracy theories including that his career was severely limited; in 15 years employment post-Challenger Thiokol only promoted him to VP of Engineering rather than CEO.

Remember, there were 3 o-rings so everything was ok even if one failed...

Today it's becoming uncomfortably clear that a person, regardless of intelligence, can fall into delusion and totally separate themselves from reality. For example, there are good engineers out there that are also flat earthers.

Remember, there were 3 o-rings so everything was ok even if one failed...

The Challenger report states that the primary o-ring was a single point failure because the design could not guarantee that the secondary o-ring would work as intended or desired

 

[LittleInch]

I guess the Titan was like the first O ring being burnt, but no one replaced it....

In both of these cases, all the warning signs were there but ignored / overridden due to other forces and egos.

I don't think though that anyone else will ever make a carbon fibre hulled submersible. So at least there is one positive out of this mess.

The original SRB design hsd 2 o-rings. The redesign included a third.

It's all in the report that NASA noticed it, and measured the degradation down to the mil; the issue was they never had complete blow-through, even though they had lots of cases where the 2nd o-ring was also degraded.

They simply got complacent, complacency which was duplicated with the heat tiles getting damaged from being hit with ice for the 2nd disaster.

I would not call that person a good engineer.

 

[thebard3]

Tug might be talking about me. I might tell people I'm a flat earther, but it's only because it pisses them off. Then I would get to go on a junket to Vegas with other flat earthers, get TV interviews, gamble, spend the night with hookers, and say it's all in the interest of science.

Manned submersible, possibly not. There already are unmanned submersible vessels using composite hulls, and they work for the depths they were designed for.

"Through comprehensive engineering studies conducted in partnership with the Office of Naval Research, CET has developed advanced engineering models to optimize the performance and structural integrity of underwater carbon fiber pressure vessels. By leveraging cutting-edge materials science and computational analysis, these models are designed to predict how pressure vessels will perform under extreme deep-sea conditions, ensuring maximum durability and efficiency. To confirm the accuracy of these models, CET has subjected numerous pressure vessel designs to rigorous implosion and cycle tests at the Woods Hole Oceanographic Institute (WHOI) Hydrostatic Test Facility. This validation process, to deep-sea pressures, has thoroughly proven the reliability and precision of CET’s models, further solidifying our expertise in the development of high-performance marine technology."

Well i suppose they are doing it properly.... Even so its now going to be a difficult technology to sell I suspect.

You don't get it.
That's engineering humour.
A good throwaway line at parties, that is never taken seriously;
"I'm a member of the Flat Earth Society".
Some engineers even join the Society to support their joke.

Is membership in the "Flat Earth Society" mandatory in any law schools?
It would be excellent practice for arguing a known falsehood.

How do you feel about religious engineers? It seems like the two characteristics should be mutually exclusive.

We have a captain that is also a flat earther.

People can be very good at compartmentalization.

since cats haven't knocked everything off the Earth by now, then the Earth is not flat. QED.

Regarding compartmentalization: in the late 1980s/early 1990s I worked with a professional land surveyor who was an adherent of Religious Science, which (as I understand it) believes that the physical world is an illusion. At the time, we had an AutoCAD drafter who had Bachelor's Degrees in History and Philosophy (double major) and was then working on a Master Degree in History (he later started a PhD program in History, but I lost track of him and I don't know if he completed it). When the drafter questioned the surveyor about the obvious problem of measuring a physical world that he believed was an illusion, the surveyor went full "deer in the headlights." To add to the irony, his wife, also an adherent of Religious Science, was a veterinarian.

I am a card carrying member. And it's no joke.

Fel3, was the person still a good surveyor despite their beliefs?

He was excellent.
