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.
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.
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'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.
Subs have dual hulls so they can fill the void between them with water to sink, or air to float, but they don’t dive anywhere near as deep. Most regular naval subs operate above 800 meters. They only have to be below the surface of the water for stealth, not at the bottom of the ocean.
This craft was a single hull design as far as I’m aware, designed with a rigid hull to try and counteract the pressure at the bottom.
