If it did implode in multiple pieces it means the experts were right; many said that carbon fiber was a poor choice because while it's light, it breaks like glass, contrary to steel which tends to "open" slowly.

I felt it was kind of telling that they found the two titanium end caps in the debris field, presumably intact, but only pieces of the pressure hull.

I'm curious if the window remained intact. This seemed like a logical failure point.

Based on this it seems pretty likely that it immediately imploded and the ‘banging’ was from the Titanic debris itself.

The banging was likely the sound of hundreds of news organizations flogging this story to get more clicks.

compared to the little coverage of the vessel carrying hundreds of migrants which capsized and sank in the mediterranean, and, by factor of sitting, watching, and waiting without intervening, were killed by the eu and greek coast guard

Stockton Rush (OceanGate's CEO) was known in the Seattle tech community [0] My understanding (very much not first hand) is that he was seen as an expert in the specific engineering disciplines necessary to safely build and operate deep sea submersibles like Titan. He was also apparently a father to members of the Seattle tech community, who are no doubt grieving at the moment. Please remember that, for some members o…

Not gonna shed a tear given how avoidable this entire tragedy was, and how terribly managed and selected his engineering team was.

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.

I am curious how we (the society) justify the shared costs incurred in searching for people involved in such a reckless mission.

The same way we justify the significant resources devoted to the attempted rescues of the Thai boys in the cave and the Chilean miners.

At least he died doing it and not someone he employed.

It's also probably related to the "launch or die" ecosystem that Y Combinator, Sand Hill investors, and pretty much the entire ecosystem promotes. When was the last time an investor handed an additional $10 million check for 0% to a startup to improve and test their safety systems before launching? Instead their usual mandate is "launch yesterday or die". Which is okay for a SaaS platform or grocery delivery app, but…

Well "move fast, break things" is fine in certain contexts... SpaceX could be said to have done that. Their first few launches exploded. But they put in the engineering discipline, extensively tested all new/innovative processes, and they didn't dare put a human or even a paying payload on top of their rocket until they'd done extensive work on the test stand and actual launches.

You can move fast and innovate in life-critical systems so long as you prioritize the engineering and testing.

Does the search team/agency simply eat the cost or does the cost get passed back to the insurance for the company, the company itself, or the CEO personally since he has the means to pay. Further, everyone on board has the means to pay for a recovery, should they too share some of the cost?

I believe almost all Search and Rescue is free because S&R organizations don’t want people to hesitate to call 911 (or equivalent) because of cost concerns, and have the situation deteriorate while they delay calling.

As to who should share in the cost… my take is that it’s time to discuss whether some expeditions (e.g. risky commercial tourist rides) should sign a Do Not Rescue pledge before they head out and/or self-fund a commercial rescue operation.

Or half the east coast. The implosion[?] of the ARA San Juan was supposedly heard 6000km away by hydrophones at Ascension Island. ( https://www.ctbto.org/news-and-events/news/ctbto-hydroacoust... ) Or maybe they did and the data hasn't been processed/made public yet.

San Juan was 2300 tons and is made of metal. Titan was 10 tons and mostly made of carbon fibre.

It also probably was armed with torpedoes when it was sunk, which probably detonated due to the explosive decompression.

Ah, I see he's got the 'Elon Musk school of thought' in regards to cutting corners in vehicles carrying people's lives and seeing safety regulations as a nuisance hindering his "visionary progress" that these pesky gray-beard engineers just can't grasp. Fucking idiot CEO, took 4 innocent people with him. Aero, naval, automotive, all have a a history written in blood, and all those rules and regulations aren't to hind…

I support the hate but don’t compare this to Elon Musk, his companies have taken more people more places safer than dozens of other competitors. Tesla is one of the safest car brands to drive, SpaceX has yet to kill or maim anyone.

Yes, and SpaceX's approach to safety and testing is significantly different for crewed and uncrewed rockets.

Forgiveness. We frequently forgive stupid a5es, and adopt regulations to prevent other a5es causing too much damage. It was Jesus' message, after all.
