From the article it seems like this ROV doesn't have sonar, and can only search visually at a short distance. They claim a distance of around 20 feet. I'm surprised they could find a debris field so fast with such a small range of observation.

Turns out that the debris field was only a few hundred meters from the bow of the Titanic which is approximately where they lost contact in the water column, so I suspect their search consisted of diving to the last known location of the Titan and then just going to the sea floor from there.

It appears to me that for all the rushing about (which was appropriate and neccessary if there were any surviors or surface debris to be found at all) the somewhat grim reality is:

1) hydrophones heard it implode at the same time it lost contact

2) it took until early 6/22 to get a deep-diving ROV on site

3) once the ROV got to the bottom, it swiftly found the debris from the implosion as expected

> 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.

maybe so but a lot of contributors here are pretty loaded and could def drop $250k on something on a whim

Carbon fiber is a lot easier to work with than metal in this case because welding metal creates failure points. I don't think they could afford building a titanium pressure vessel. Weight is a factor too, carbon fiber is lighter so you can make the pressure vessel thicker and still have enough buoyancy to reach the surface(probably a good thing). From their perspective it kinda made sense even though its not safe at…

Obviously there seem to be some compelling reasons why the choice of a carbon hull was a faulty idea to begin with. The CEO would have been familiar with those critiques and proceeded anyway, presumably because of counter arguments he put more confidence in. Anyone out there familiar with what some of those counter points may have been?

Their website extensively mentions the acoustic monitoring system, with the thinking that any stress fractures would be detected prior to failure.

It probably did, but unfortunately, I think the window of time was not enough the return to the surface (perhaps milliseconds, but who knows)

Sometimes I wonder what it is that enables some people to have empathy for strangers but others not. Is it mostly your upbringing? Genetics? Can people like you be fixed, or are you incorrigible?

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

You must live on the coast. There's plenty of us in the midwestern US that could never make it to a coast before the boats were all gone.

Not that it involved a catastrophe but most of those people had been traveling dangerously for months to make it to Libya (or Egypt?)

A migrants boat. Most of the people crossing the Med into Europe are economic migrants but in the past decade it has become known that claiming asylum on arrival (or at least if caught) is a good strategy so many do.

He's also on record as saying things like, " It's obscenely safe because they have all these regulations. But it also hasn't innovated or grown — because they have all these regulations. " ( https://www.insider.com/titan-submarine-ceo-complained-about... )

He seemed especially proud about combining titanium and carbon fibre against the advice of others, which seems to now have been in a pretty active role in the demise of the Titan. > "I'd like to be remembered as an innovator. I think it was General MacArthur who said "you're remembered for the rules you break." And I've broken some rules to make this. I think I've broken them with logic and good engineering behind me…

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

> how we (the society) justify the shared costs incurred in searching for people involved in such a reckless mission

Nobody asked me if I want to pay for it or not. So i don’t feel that the “we” is justified. But if they would have asked me i would have voted to not move a finger unless some private entity (the company or the families, or literally anyone who wants to) pays for it.

They went out of their way to do something knowingly recklesly dangerous, and the cost of any rescue attempt is enermous.

I think the idea of being trapped in a confined space kilometers under the sea has a visceral effect on the imagination that a boat voyage on the surface doesn't, regardless of how tragic the outcome is in both events. It pokes and prods many of our deep phobias. Similar stories like the Thai boys trapped in the cave, or the Chilean miners, had a similar effect. A bit like "Snakes on a plane". Again, trapped with you…
