Something I've learned over my life is not to automatically trust that someone has done or will do the right thing just because they stick their neck out. Sometimes they stick their neck out because they don't actually understand the risks and consequences, but they are pretending that they do. They're artificially signaling confidence. In this case, the CEO risking his life on this third(!) voyage means 1 of 2 possi…

The target of the adventure is also surprisingly ironic.

The Titanic is one of the most notorious icons of human hubris. And these tourists died to the same.

Interesting a commenter on the video notes the pressure there is equivalent to only 10 meters underwater. Imagine the force 2 miles below

I am probably too stupid, but how is that possible? A lot of divers go 10 meters underwater and don't die of pressure, right?

Well, sea level is at 1 atm already, so an increase to 2 atm isn't immediately catastrophic. However, if you took that tank filled entirely with sea level air and shoved it down 30 feet under the water the same thing would happen. It instantly crumples because its hollow. We're full of water with some air in a couple places. We'd crumple too if we were just a layer of skin over an air sac. But as it stands, the human body can withstand that pressure alright

Well, this explains a lot... they didn't have a window rated for the right depth and weren't really testing whether the hull was de-laminating according to the whistleblower, so we have a few guesses as to why the sub would just implode. The lack of contact would be because nobody was alive to contact, which is honestly better, at least they had a quick death instead of slow suffocation. And the banging noises are pr…

Probably combusted? At 400 atms their biomass would compress into a gelatinous hydrocarbon fat blob with the oxygen present, resulting in automatic combustion. The amount of compression their bodies would experience is an order of magnitude greater than a diesel engine cylinder. The explosion would immediately be quenched by the surrounding water and the only thing remaining of the occupants would be ash. This would…

Someone put Mythbusters on the case

They sorta did one like this ...

Pressure at that depth is about 5800 psi. Imagine 3 ton, 1 cubic inch cubes being dropped on every square inch of your body from every side all at once and you'll have your answer.

Hmm, but human body is mostly solids and liquids, not very compressible. Their lungs and airways, sure, would be compressed to nothing, but what of the rest of their bodies? Eg I'd imagine the poor souls on the Titanic next door are not crushed by the pressure, for the same reason. Or with scuba diving, deep scuba is complicated and dangerous for many reasons, but the pressure compressing the body is not one of them.

i'd assume the air forced into various cavities (especially the skull) would send shock waves into neighbouring tissue ripping everything apart upon surge of pressure. also probably lots of turbulence creating shearing forces also ripping everything apart. so, everybody ripped apart. titanic victims sank slowly allowing for continuous evacuation of cavities. air streaming out and water in.

Is there anything the NY Post can't try to blame on wokeness? The objection seems to be age, not race: > “I wanted our team to be younger, to be inspirational and I’m not going to inspire a 16-year-old to go pursue marine technology, but a 25-year-old, uh, you know, who’s a sub pilot or a platform operator or one of our techs can be inspirational,” said Rush. Not an uncommon scenario at startups.

It's different when your company deals works in a life critical space.

That suggests it was the carbon fibre shell that failed. If it was the Plexiglas that failed (or other part of the end bell assembly), I'd expect the pressure to quickly equalise though the failure point and the carbon fibre shell to remain relatively intact and hold those end bells together. Though, I'm not an engineer. Maybe the rapid change in loading could result in the carbon fibre shattering.

I'm curious why Stockton Rush thought carbon fibre would be enough? I'm trying to find out how it would be sufficient. I'm sure we'll find out more later why it failed. https://en.wikipedia.org/wiki/OceanGate#Design_and_construct...

Apparently another sub was made with carbon fiber and it worked fine, however that one only had a single dive because they knew that it would lose strength after each dive. It may be feasible if they had replaced it more often (I don't think they ever replaced it, and there were former staff who claim to have brought up concerns about its condition).

Almost as interesting as this story has been the comments online. Everyone, everywhere just parroting and re-parroting the same comments, attitude, pretending to understand the engineering with snippets from comments they’ve read, reactive talking points, etc… Very strange. Did anyone else feel like an alien following this story online?

Not really. I work with a company that does this kind of stuff (deep see exploration vehicle design), materials science is a tricky but very interesting subject. When someone seemingly does 'the impossible', subjects paying passengers to extreme risks and throws the rulebook on safe design out of the porthole you can bet there will be an entry in 'Risks Digest' at some point or another. Carbon fiber is a great materi…

> What I didn't understand is the focus on the electronics and the control system, those are irrelevant if the hull isn't going to work out.

Two reasons, I think. First, the (apparent) shoddiness of a control mechanism is easily understood, whereas the reasons why carbon fiber makes a poor choice for a pressure hull are more difficult to understand. Consequently, the use of a game controller is a more salient example of a company cutting corners than their choice of material in the pressure hull. (This is somewhat undermined by the fact that a game controller actually isn't necessarily a problem--Ars Technica ended up running articles on consecutive days with the first one being a tee-hee-they're-using-a-game-controller article and the second one being a why-the-military-uses-game-controllers article.)

The second reason may be that some people would rather focus on the potential failure that admits a possibility that the inhabitants are alive instead of potential the failure that guaranteed their death before the search started.

3) Something else than naive

"The OceanGate CEO who is trapped on a 22-foot submersible on an ill-fated voyage to see the Titanic wreck once explained how he didn’t hire “50-year-old white guys” with military experience to captain his vessels because they weren’t “inspirational.”

The CEO, Stockton Rush, added that “expertise was unnecessary” because “anybody can drive the sub” with a $30 video game controller." [0]
