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.

If it was actually them, I'd guess they were banging on the titanium end cap.

Oh yeah, I forgot about that part of the sub, lol. Whoops

No worries! We're making a lot of assumptions here either way.

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
