i understand what you are basing your statement on (a cleaner version would be asphyxiation by breathing an inert gas) but you are very wrong. as a matter of fact people with an impaired amygdala who can't experience fear will panic when forced to breathe co2. also your breathing will get very shallow and cause co2 to accumulate triggering those very receptors you argue will stay silent. https://www.nature.com/articl…

But kids and people die regularly due to having a barbeque thing lit in a close space and the coals consume the oxygen and make CO2. Wouldn't that wake them up? I also assumed that too much CO2 fast is the key not the super slow version of what those people in the sub have experienced

what you mean is CO - not CO2

What can we learn from this? Don't go in pressure vessels; don't go in confined spaces.

There are a number of reasons why it might have failed, fatigue, deviation from process/protocol but pressure vessels are well understood and not the problem here.

The main cause for the failure seems to be "sheer f-ing hubris," but those could certainly be contributing factors.

The outcome everyone knew would happen. I don't understand the desire to go to that depth to see a sunken ship when I presume there is camera footage of it available. You can't get out and do anything, your view is probably pretty crappy given the thickness of any see through material. I see the allure with Everest and the view for your 60 seconds at the top must be impressive and it is a physical feat. But a sunken…

The desire is motivated 100% by bragging rights for the uber rich. So they can recant their journey as an intrepid explorer (/s) at a cocktail party with their other smug uber rich friends. Same for going to space.

Was the company insured for the massive cost of the rescue attempt? Do they have enough assets to pay for it?

I would be surprised if there was no criminal negligence or something like that in store for them. At least going on by what was published, the company functioned in a way that made it essentially guaranteed that something like this will happen ... while having no real "in case of catastrophe" plans in place.

Yes, who cares if someone killed a child and several other adults by repeatedly ignoring warnings of clear dangers! Why shouldn't people be allowed to experiment with negligence at the cost of human life?

Now, it would be really interesting to know whether they really knew actual risk involved. Not just that they might die ... but also how likely it seems to be.

Also, hating someone does not imply wanting them to be dead. Not all of us are want to kill people we find assholes. Sometimes we just want them to have less power so that they cause less damage.

> The late CEO of OceanGate told David Pogue last fall, “at some point, safety is just pure waste.” In and of itself, what is actually incorrect about that statement? I think a lot of normal people are going to smugly harp on that statement, but in and of itself it seems perfectly reasonable to believe that there's a diminishing return to safety measures for anything at some point. The issue with this sub thing seems…

They were pretty far from that point when he said that.

Just thinking about that outcome yesterday caused my blood pressure to skyrocket. Dark, cold, cramped, fetid, hungry, thirsty, knowing oxygen is running out.

These kind of long, agonizing, pointless deaths are all too common when dealing with the ocean. There was a horrifying case after Pearl Harbor where bodies were found in the airpocket of the USS West Virginia. They had flashlights with batteries and fresh water and had marked off 16 days on a calendar. Legend has it that sailors could hear banging for weeks knowing they could not cut through the thick battleship armo…

Are carbon-fiber pressure vessels well understood? I get that there's a lot of armchair quarterbacking from internet material experts here, but this does seem to be an outlier with this particular submarine.

I think their behaviour under pressure is well understood. Not a popular choice for subs, though.

Somewhere a redditor did the math and I believe it would have taken 24ms for the glass to break and the water to rush in. Instant death if it was indeed the glass.

Just how instant is that death? Do you die from quickly drowning in the water or is the water pressure enough to also crush your skull quick enough to make sure you die without having the chance to feel anything? Guillotined people can still be alive and feel about 30 second safter their head has been removed from their body.

It would be more like dying from a shockwave from a massive explosives blast. You're going to turn entirely to jelly. Within a few ms there will be nothing left working properly.

Do airplanes count?

Also the airplane shell has to endure tension forces, as inside has greater pressure than outside, whereas the sub has to endure pressure. Some materials work well under tension but not pressure and vice-versa.
