Something about tragedies, and something about statistics... But there's also the concern of frequency, [2] occurs more frequent than [1], people generally don't care about the people at [2] because they are "unimportant", and not prominent in any way. They are background characters on the other side of the world for many, they are not well dressed, they do not perform functions with significant influence on the broa…

The comparison between these two stories is being made (elsewhere on the Internet) because humans were literally still being found and fished out of the Mediterranean, alive, while entire nation states mobilized to try to rescue a few wreckless rich guys who were likely already dead. The point being made is about misallocation of resources, not news coverage. (Novel stories will always grab more attention.)

The families of the missing rich people have the resources to fund the search. The families of the missing people in the Mediterranean obviously do not.

Immediate implosion if a far more likely explanation because give that we knew it imploded the most likely time would be immediately after the pressure vessel reached maximum or near maximum stress and it failed. The time actually is not the biggest factor; it is the number of cycles the pressure vessel has endured. An implosion after a relatively low number of cycles is consistent with past incidents with pressuriza…

The most puzzling aspect, from what I understand from the experts, if it imploded at time and depth you are suggesting it would have been very likely to be registered by at least the controlling ship due to the noise. As you highlighted the sub is pretty large, imploding in a millisecond causes huge effects in the surroundings. So saying it got lost and imploded after a few days solves two problems. Explains why ther…

They mentioned in the press conference that it was very unlikely that the implosion would have happened after more listening equipment was in use on the scene. I believe there were sonar buoys dropped on Monday, so the implosion likely happened before then.

I agree with your observation but Mediterranean disaster had coverage since last week at least in European news I am following. This accident will also soon disappear from the news since we now know the fate.

How many rescue ships were deployed to the med incident? How many to the titanic? The victims/ships ratio demonstrates that one garnered exponentially more government attention.

different countries of very different sizes and capabilities were near the incidents.

the US and Canadian coast guards don't operate in the Mediterranean, and (presumably) couldn't have gotten ships there fast enough to do anything about it, anyways.

What I don't understand is, if it imploded, why didn't the boat hear the implosion? Surely that would be really loud. Louder than the 15 min audio ping that the boat is normally listening for.

have we ever identified an implosion from carbon fiber? does it matter?

Well, that's a conclusion that I suppose many expected. It's rather tragic, yeah. What I can't say I expected is the gleeful tone from: - class warfare enthusiasts because the passengers were rich - regulation enthusiasts because the pilot espoused weakening them You'll see this online when a pedestrian or cyclist gets hit by a driver (along with "right of way doesn't mean anything when you're dead!" and "was he wear…

We're not allowed to "eat the rich" anymore because of the repressive nature of the neo-liberal system, so incidents like this one where not one, but two billionaires find their gruesome death is the closest to a Middle Ages egalitarian-imposing peasant revolt that we could ever get. Sucks for the 19-year old kid involved in all this, that I agree with.

What a ghoulish take

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.

The size is irrelevant, the energy released is significant either way and definitely beyond the thresholds of hydrophones. During the USCG press conference today it was stated that the implosion made a significant soundwave as a result of the implosion, and I think in the coming weeks we'll hear reports of findings in regards to hydrophones which picked up the noise.

> the average person here is probably a lot closer to taking a holiday trip in a submersible than to taking a refugee boat across the Mediterranean There is no way in hell I would pay $250k to board a janky-ass sub going deep into the ocean. For $250k, I could buy a nice house for me, my girlfriend and our future family. And even that is not possible yet. Because I don’t have that kind of money.

Reminder too that literally everyone is one country-ending catastrophic event away from being on a refugee boat

Only those near a coast, actually

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…

"Two months later, OceanGate faced similarly dire calls from more than three dozen people — industry leaders, deep-sea explorers and oceanographers — who warned in a letter to its chief executive, Stockton Rush, that the company’s “experimental” approach and its decision to forgo a traditional assessment could lead to potentially “catastrophic” problems with the Titanic mission."

It is notable how much news-coverage this received (for understandable reasons [1]) relative to the almost simultaneous disaster in the Mediterranean [2], where a shipwreck killed hundreds of people.

In European news both events received significant coverage.

Local news trumps global.

I am sure in Greece the Messenia migrant boat disaster got more coverage than Titan.

That said, the big factor is how sadly common migrant boat disasters are (just like liquid gas exploding in a restaurant in China and killing 10+ people, happened yesterday).

Carbon fiber submersible on the way to Titanic containing cocky inventor, plus billionaire, plus kid hits so many spots for news cycle.

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

I hope the other souls onboard fully understood the risk of death, otherwise that isn't fair to them.

To relate it to flying in an airplane, “If you take one flight a day, you would on average need to fly every day for 55,000 years before being involved in a fatal crash.”

I'll take those odds.

Take a deep dive in an experimental vessel with public safety concerns expressed over years, nope I'm out.
