More than that, one report mentioned the US Navy notified the search teams that they heard an explosion Sunday night and used it to limit the search area. The US Navy has literally has experience detecting underwater explosions (see project Azorian). It's not guaranteed of course, but any loud sound near the point of contact loss seems pretty open shut. Imo, it made a more interesting story in a slow news cycle. How…

From the date of lost-contact (18 June 2023), there have been 13 deaths from mass shootings in the US. https://www.gunviolencearchive.org/reports/mass-shooting

I’m not exactly acquainted with the topic, but that feels like a slow week?

depending on the failure type (shear, compression, tension) carbon fiber behaves differently. but when the fibers actually break it pops so quickly that it exceeds human perception. real time view of tensile failure: https://youtu.be/gmMRPmEYWhU high speed 10m fps view of tensile failure: https://youtu.be/OePpVwCvCZg when compressed along an axis that's not properly reinforced by carbon fibers, it will just disintegr…

The same guy that runs the channel as your last video actually did one on imploding objects under sea depth pressures: https://www.youtube.com/watch?v=WD7CfnQC5HQ

Note that their pressure gauge only goes up to 4500psi. The water pressure at the Titanic's location is around 6000psi.

> [Cameron] and other submersible industry experts believe that the system worked. Cameron did not say "the system worked" nor do I agree with summarizing what he did say as "the system worked." The claim in the blog post was this: > With this RTM system, we can determine if the hull is compromised well before situations become life-threatening , and safely return to the surface . It obviously did not do that. The sy…

Cameron implies that the system did detect a crack in the hull, giving them at least a few minutes of warning. Obviously, a few minutes isn't enough, but the point is that the occupants were likely aware something was wrong because of this system, as opposed to being vaporized without having enough time to comprehend their reality.

I only take issue with saying that the system worked. It didn't work, since it was designed to detect failures well in advance which it did not do. Almost only counts in horse shoes and hand grenades.

I wonder if they knew they were doomed or whether Rush was telling them not to worry to the very end. Personally, I think I would have rather been vaporized without the minutes of terror beforehand.

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?

The carbon fiber obviated the need for expensive to produce syntactic foams.

The Bluetooth?

Eh. It was there.

The sad thing is, the carbon fiber hull material may not necessarily be a totally losing proposition if you can make the carbon fiber hull module swappable and recyclable, and testable.

Evidently they got, what? 20ish descents to service depth before it lost integrity?

If you worked from there, and figured out those pesky details, you could make something workable.

In fact, we may even be lauding the man if they'd done the 30 + journeys to service depth unmanned, and used the data collected from scanning/ultrasounding or otherwise probing that hull piece to draw strong, clear, unambiguous bars around "number of trips til new hull needs to be swapped in".

Nobody would fault the guy for doing that, and he may have truly advanced the State of the Art in ways he'd still be alive to enjoy.

But here we are.

No amount of poor decision making changes the fact that several precious human lives were lost. Frustration over the company's potential negligence and sadness over the loss of life can coexist.

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…

Apparently being ageist is now "woke". What an incredibly flexible term the right wing has appropriated! Conservatives Are Now Blaming The Titanic Sub Tragedy On 'Wokeness': https://news.yahoo.com/conservatives-now-blaming-titanic-sub...

This is a harmful comment. Ageism is a real issue in tech and we should be able to talk about it constructively. It's unfortunate you responded to such an opportunity with a shallow invocation of a political wedge issue.

As Jon Stewart once said "Please stop hurting us."

It happens :) I do on occasion ramble on with unpopular opinions or say things which are probably incorrect

In that case, maybe you're just human like the rest of us.

There was never an indication the comment was supposed to be excluded from the generality. If anything, this thread is just showing it to be more likely (me included). The only way not to show it as such is to get an actual expert on the topic to post an informed opinion with reasoning or citations. This, as the original comment suggested, seems much less likely than us continuing to talk about it instead :).

This quote shines light on his hiring philosophy: “When I started the business, one of the things you’ll find, there are other sub-operators out there, but they typically have, uh, gentlemen who are ex-military submariners, and they — you’ll see a whole bunch of 50-year-old white guys,” Rush told Teledyne Marine in a resurfaced interview. “I wanted our team to be younger, to be inspirational and I’m not going to insp…

Wow, could be a Musk quote. Same vibes of 'break things fast'. EDIT: "Hide yo kids, hide yo wife; the karma snatching Tesla fanbois are rife"

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

Are you seriously trying to suggest that less experienced engineers are better than more experienced engineers?

Hubris like this will leave you joining the other ghosts floating around the wreck of the titanic shortly.
