While on principle I agree. It doesn't matter. There can be 2 problems at the same time. Whatever people focus on shouldn't be a topic. Edit: That seems far more callous than it was meant. You're right, people are forced to travel the sea almost daily, desperate people will do anything. This IS different. And hits different because it was a choice, with a real discussion about "Hey, it's really possible you can die,…

>There can be 2 problems at the same time. >Whatever people focus on shouldn't be a topic. On the contrary, I think what people focus on is irrelevant topic for reflection and more importantly introspection. It's important to know what Yanks your emotional chains and who is yanking them. Looking at what drives public attention lets you know what people really care about, not what they might say they care about. You c…

I can't argue with that actually, I just think there is a time and place for that introspective reflection.

I do agree with you, though I think BT game controller wasn't a bad idea for two reasons: - Battle-tested and easily replaceable, compared to a custom one. - Cables have a snapping risk in that limited physical space, Bluetooth solves it and there's no risk of EMI 4km underwater anyway. The carbonfiber structure... that's another story. Terrible.

The Logitech F710 was not a "battle-tested" controller, it's a cheap third party controller of inferior quality. The official Microsoft controllers have serious R&D behind them, but not the Logitech ones.

third party doesn't mean anything if you're not controlling a first party device

The most troubling thing about this to me is Stockton Rush’s cavalier attitude toward ageism [1]. In considering young college graduates as uniquely “inspirational” he set them up for a lifetime of guilt. I don’t think age or race has any place in inspirational calculus. I’m uncomfortable with how comfortably he dismisses submariner veterans as “old white guys”. Engineering is a discipline that requires experience an…

>This is a lesson the entire tech industry would do well to meditate on. This is a lesson everyone in the business of making things would do well to meditate on. Age and skin color, let alone sex, don't a good product make. It's whether the people involved have what it takes to make a good product. OceanGate clearly did not have what it takes, even if they did check all the proper identity boxes.

> OceanGate clearly did not have what it takes, even if they did check all the proper identity boxes.

I don't think the ageism was some kind of identity politics - I assume it's b/c veterans refused to sign up to such an unsafe project, and the guy sugar-coated the dubious hiring practise by implying it was his choice not to hire them.

Bluetooth as the only means of control of a sub that would most definitely kill you if it loses control? The same battle tested Bluetooth that still can't reliably connect to the exact same device despite having done so all the time? The same Bluetooth that disconnects if I were to turn on 2 more Bluetooth devices due to interference? How about the batteries that are required to power a wireless controller? Everythin…

The other major issue with the controller is that it is not designed for a marine environment -- the water, salt exposure, and humidity inside the sub. Surely there are off-the-shelf marine controllers that are better suited.

Apparently being ageist is now "woke". What an incredibly flexible term the right wing has appropriated!

He might as well have said I couldn't inspire a 60 year old veteran in the field to work for me like a slave for pittance of a salary. In engineering experience and precision and discipline matters a lot. OTOH I hope he still is alive somewhere somehow down there and gets rescued, but he does speak like a douchustler.

I don't think he even offered the 60 year old veterans a chance. Probably a few of them would have advised a bit for free.

Most old engineers I’ve worked with are terrible and many younger ones are way more talented.

Sounds like you need to find a better job. Good luck, with that attitude.

As I understand it: the pressure vessel was full of air, and at the moment it failed, that air-filled space became the equivalent of the cylinder of a 2-stroke engine, instantly heating as the air compressed.

You probably meant diesel engine. The compression pressure of those is around 300-500psi, and that's sufficient to heat the air to a few hundred degrees and ignite the injected fuel. For comparison, what happened in this sub was 10x that pressure. (Yes, 2-stroke diesels also exist, and sound absolutely amazing.)

Much higher than that. The external pressure was ~6000psi, but water has inertia. The peak pressure as the bubble imploded was many orders of magnitude higher than that.

This is the attitude you need to give birth to truly innovative ideas like a Bluetooth controller attached to the desktop PC that controlled his hunk of shit submarine that killed everyone on board. He proudly describes it here: https://www.youtube.com/watch?v=ClkytJa0ghc

Does he ever explain why carbon fiber and bluetooth were improvements over working technology?

To lower costs in order to attract more billionaire customers.

The looking glass was only rated for 4,000 feet. Implosion happened around 9,000 feet, which would suggest the glass handled over twice its rated depth.

and survived several dives before that to 13000ft, no?

Pressure cookers that are rated for 15 PSI typically come apart at 75 PSI.

But that’s the thing about ratings. The manufacturer guarantees safe usage at 15 PSI and anything above that all bets are off and you’re on your own. Same with milk and expiration dates. Many times the milk is fine after the date, but the dairy won’t guarantee freshness and food safety.

Same for this looking glass. It says what the CEO thought about safety. He was willing to take chances and roll the dice. And every once in a while you get snake eyes. The consequences of rolling • • at 9,000ft of depth in the ocean is sadly instant soup. The water entering the vessel would likely be 5,000F degrees or so. While some people say it would be an instant death and not consciously detectable, I disagree. I think they were given just enough time for the brain to go oh shit, but only got to the oh part, and lights out.
