    There’s nothing to rescue except a waterlogged carbon fiber tube filled with gore.

      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

      It sure sounds like they’re likely alive based on the reported banging. Sadly rescue before oxygen runs out seems impossible.

        They were alive, which is very very sad, but if they lost power (seems likely) then without heaters they would have froze to death a couple days ago.

          That’s what an article emphasized that I skimmed through. The sub had automatic pinging, and systems to automatically raise it to the surface if an untoward event happened. For communication and pinging to be lost, as well as the lack of floating submersible… It’s likely whatever happened buggered the whole setup. The banging also was supposedly heard in 30 minute intervals, but no one is saying how many of those intervals happened. The banging could be from anything. The deeps get strange, and the water distorts much of what we know. Multiple people with knowledge from other searches, like the 2014 MH flight, said banging was often heard during their searches but it was always from other sources.
