@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
Carbon fibre is great until it isn't. If I was a billionaire, I'd check the damn hull out before every dive. 4000 = metres = atmospheres of pressure!

The next closest is 500m. Which exceeds the 130m of the nuclear sub Thresher.
