Pretty sure these trips cost in the 6 figure range. I don't have a ton of sympathy for people that rich.

However they are possibly going to die in one of the more mentally terrible ways. In the dark, slowly running out of oxygen with no chance of escape. It's only slightly better than being buried alive in a casket.

The more likely scenario is that the hull of the sub was compromised and they died instantly as it violently imploded under the intense water pressure.

I don't know about that. It sounds from the bits I've watched, the part they actually put resources into was making it structurally sound and able to withstand pressure. The entire rest of the submersible seems to be super macgyvered up so something like an electrical failure taking basically the entire craft offline or the ballast tanks being hosed up and making surfacing impossible seems just as likely as a catastrophic failure of the pressure vessel.

I dunno if they'll ever find this thing though.

How is this supposed to surface after it sinks normally? It kinda sounds like it can't surface on it's own and relies on that platform thing so if you lose thrust, or possible even if you just lose one thruster, you're SOL. Don't most submersibles like have some kind of ballast tanks to blow or weights to detach so they can surface quickly?

Having a separate platform thing you need to dock to feels like a very unnecessary thing that creates an extra fail point in the whole process.

My dumb theory:

They got to the correct depth fine and started scootin around the titanic as planned.
The electrical system failed, leaving them without propulsion, communication, and lights.
Because of the above they could not dock with the recovery platform thing and are kinda just stuck at the bottom of the ocean.

This could have been solved by just not having a loving recovery platform it needs to dock with and just giving the thing it's own way to surface, ideally any control of this is either directly mechanical or has some kind of redundant back up power, because not being able to surface is bad.

Even if it turns out that the pressure vessel failed, having a separate platform the vessel needs in order to surface is the dumbest poo poo ever.

Okay, yesterday I posted how I didn't know if the sub had its own way of surfacing without the platform thing. First it didn't look like it really had any kind of ballast tanks it could blow with pressurized air. It had some kind of tank on the outside, but that looked too small for this purpose. Second, and more relevantly, they had ballast weights on the outside, which can often be released to allow them to surface, but these were like resting on fixed hooks and the skids on the bottom of the sub. I thought there was no chance these were intended to be removed for deballasting because it would involve the crew desperately rocking the sub around trying to get them off, which seems deeply stupid.

It turns out they did the deeply stupid thing lol.

Death By SnuSnu posted:

Let's say they do have some ballast situation going on. I feel like they would have issues from ascending too quickly because I doubt it would have any way to slow it down. So if they don't die from an implosion, lack of oxygen, or freezing to death they would definitely die from the bends.

Since you arent directly exposed to the ocean pressure, the bends wouldn't be a problem I don't think.

Even if by some miracle they manage to find the submersible intact on the ocean floor, good luck trying to recover it from there.

Also finding a bottomed out submersible of that size is very difficult even with modern side scanning sonars.

Yeah, basically their best scenario at this point is they were instantly killed when the pressure vessel failed. Every other scenario is a nightmare.

I assume the billionaire killed the others on board the second things started going wrong so I figure 96 hours of air for 5 people is, what, 480 hours for one dude?

At the very least we can assume everyone else murdered the CEO as soon as they were stuck, so like an extra 20ish hours.

Bad Purchase posted:

however, the rescue efforts should focus on the survivable scenarios, which would be that they surfaced without working comms or that they are stuck / very slowly ascending at some intermediate depth where a rescue could perhaps be attempted.

Oh yeah, the deeply stupid "Deballast by rocking the boat around" thing could easily have left them like halfway to the surface.

Carbon fibre hull. loving hell.

People have already made the point of between 0 and 1 atmospheres of pressure (:argh:). Cyclical stress from each dive will make defects more and more likely, and given general standards I doubt they've got any inspection regime. I'm now far more convinced that the submarine imploded.

... Not that it's going to be much better if they're on the surface; submarines are not designed for surface stability, so it's going to be hellish for those inside even in the most calm seas. Given the stress they're under, I doubt that 40 hours is accurate.

No transponder, no automatic ballast detachment, no internal release mechanism, no wired controls. This is great fodder for engineering safety lectures.

I originally thought that failure other than the pressure vessel was more likely because of how much the CEO crowed about how they spent so much money and resources on just that part. Since then, not only have I learned that they did that in stupid ways, but they did SO many things wrong that we likely will have no idea what caused it unless we find the sub.

Why did they go with carbon fiber for the pressure vessel? Cost? Weight? Did Elon do it for his space ships?

So if the 'banging every 30 minutes' was them, how could have sonar picked that up? What? Tapping on the inside walls somehow is picked up in the ocean by underwater drone??

Maybe them doing the really stupid "Rock the sub to knock the ballast off" procedure and taking ~30 minute breaks because that poo poo probably tires you out.

they would have dropped the ballast (which can be done with or without power)

You've made the fatal mistake of thinking they can easily drop the ballast like a normal sub. To drop the ballast in this terrible sub they needed to get the sub to rock around until the weights fell off. It wasn't like just pull a lever and drop the big weight, it was move around and hope enough small weights fall off and they'd had problems with it before.

Hell, in normal operation this thing wasn't even supposed to surface on its own, it was supposed to dock with the platform thing for the last 100m or so, probably because their method to deballast the sub was SO bad.

There's literally so many things wrong with this sub that we actually have no idea what happened.
