Wow I didn't know they were going to recover it at all. Pretty cool. Can't wait to read about how shitty the design was.

I mean, it’s well known by this point. But a “seconds from disaster” version of it would be interesting to watch as disaster porn.
This is haunting.
There's no gore or anything, it's just twisted metal and cables. Still, seeing it and thinking "humans were alive in there mere days ago" made my gut drop. It's not like looking at wreckage of an old ship or plane or something, it's different. Because it's so small, it feels more intimate. Like looking at a coffin vs looking at a graveyard

I did not expect this thing to actually be hauled to shore. Kind of thought they were just going to leave it. How much did it cost to pull that thing up?
Hopefully, examination of the wreckage will yield valuable information about the cause of the failure and help future designs of deep-sea submersibles.
We already know how to build submersibles. Engineers told the CEO that this submersible was not built to spec and not safe. He fired them.
Sure we do but there's always something to be learned from a failure. This sub was unique in it's design and while that design ultimately failed, the knowledge gained from the failure could potentially lead to an improved design that maintains some of the benefits such as low cost and high occupancy.

Normally I’d agree with you, but we already know that carbon fiber is weaker in compression than in tension and that you really shouldn’t attach it to titanium either, due to their differences in malleability.
Not-even-that Future deep-sea submersibles: "yo do not compare us to this garbage"

Both titanium support rings were recovered intact. These are what bonded the carbon fiber hull to the titanium ends. There isn't any evidence of carbon fiber still attached in the photos/ videos of the debris.
Edit: more photos
So the front AND the back fell off? Is that normal?
Doesn't matter, it happened outside of the environment.
Well it must be somewhere?
Does it have a wheel on it?

From your link it seems that even the front titanium hemisphere is still relatively intact.
Looks like the acrylic window is missing on the front dome. I wonder if it gave out first or got popped out by the implosion.
These are the non-pressurised systems that would have gotten the least damage most likely.
Ya the only damage would be from the implosion and shrapnel. Everything else was sitting at the same pressure, so there's nothing really going on to cause damage.
It's weird seeing huge pieces that look relatively undamaged. Looks like you can just throw that frame with all the electronics in the spare parts bin and call it a day lol
Whats the source?
Interesting - I had imagined it being imploded into bits like the simulations on the news show.
I believe this is the outer portion. The carbon fiber shell imploded and is probably not recoverable.
I'm certainly no expert but I understand submarines have an inner and outer hull. The inner hull has to withstand the pressure of the deep but the outer hull does not. The inner hull would be crushed into bits but the outer hull and any equipment in-between would likely be ripped into large chunks as such a violent event occurs inside of it.

The outer shell didn't hold pressure and was there to cover wires/ equipment exposed outside the pressure vessel.
like the simulations on the news show
Why would you put any faith in a simulation by an organization that has no knowledge of the domain?

I wonder if they recovered the Xbox controller?
It was a Logitech controller. I guess he couldn't spring for the pricier Xbox controller.
Have you priced one of those Pro Controllers?
Is it ironic when the billionaires who live by cutting costs get stung by cost cutting?
Controllers like that are used on nuclear attack submarines aswell so that is not the issue even though it might seem funny to someone not familiar with this stuff.
Those companies have made billions of them over several decades. It's much more reliable to go with a one like that than to develop a new one from scratch. Submarines don't implode because it was steered by a logitech controller
In a video I heard the CEO say they have spare ones on hand, just in case. But still, having my life depend on a Bluetooth device seems just wrong. Why not go with a direct cable? Much less to go wrong!
I don't disagree. I almost refuse to use even wireless headphones myself.
However all the fail-safes on the sub were quite decent in my opinion so the controller isn't really life-critical. The issue was that none of the safety features protects you from far exceeding the rated maximum dive depth. They probably didn't know what hit them.
Nuclear subs do not however use them for propulsion. Something like a very basic input delay or other Bluetooth issue could be catastrophic.
