    There are reports that acoustic systems picked up banging noises at 30 minute intervals. Until.I heard that, I was convinced it had imploded. Now I’m not so sure, and it’ll only be worse if they aren’t rescued. Implosion would at least have been fast.

      I heard about that, but I find it very unlikely that they could make a noise loud enough on the carbon fiber hull, not exactly known for it’s acoustic properties and the resin acts as a sound damper. I’m not a material or acoustic engineer though, so who knows. Plus, the article did say that the sounds had stopped.

        I believe the forward end cap (where the porthole is installed) is titanium, and exposed on both sides, so presumably that’s what they’d be banging on.

        I feel like if there was a way to dampen sounds that well then military submarines would have adopted it long ago. No idea though.

          I don’t mean it’s meant to dampen sound, just that carbon fiber that the hull is made from doesn’t conduct sound waves like metal. But someone else kindly reminded me that I forgot about the titanium cap or the sub
