@doot Someone found an article about signs of repeated stress damage to the hull when they were curious about other carbon fiber hulled subs, because turns out _that's the only one_ because it's _very stupid_ to build deep-sea subs out of carbon fiber.
I would love to see that because it confirms my biases about the stupid shit they were doing with carbon fibre.

@Homebrewandhacking comment from birdsite user I caught the link from:
>i found that first one because i was curious if anyone had done carbon fibre submersibles before, because cf can just fail on you if something goes wrong in the layup etc, and it turns out, no, no one else had @doot

In fairness, according to Techcrunch one person had tried a carbon fibre submersible before - Steve Fossett with Spencer Composites - but he died in an unrelated misadventure before they got around to using it. https://techcrunch.com/2023/06/20/a-whistleblower-raised-safety-concerns-about-oceangates-submersible-in-2018-then-he-was-fired/
If someone makes a thing but never tries it out can you still gain useful safety information?

I guess generally the making of it would be expected to involve a fair amount of testing, but even if that is done, it is probably calibrated to what the customer said their requirements were.
