People have been spitballing on this problem for generations, and that latter one’s been tried too… problem is it’s effectively the same thing as trying to pinpoint a diver by her bubbles; if she’s near the surface, works great… if she’s 4KM down then the bubbles hit the surface spread effectively randomly over hundreds and hundreds of square kilometers, and usually kilometers off horizontally.

The best way to maintain communication with a submersible is a tether. The best way to know the position of a submersible is a tether. The best way to raise a submersible in trouble is a tether… this company chose to go another way. And, let’s be clear, even if they knew precisely where it was the odds are very good that they couldn’t possibly effect a rescue.

The grim truth is that everyone aboard is already dead, the hope is that it was a sudden implosion rather than slowly freezing, drowning, or asphyxiating.

You were right man! Tragic. I'm hoping you're a navy insider and can feed us interesting tidbits about UFOs. Any stories? Do you know how the Navy detected the anomaly? Was a ship nearby or was it their monitoring grid? It's good they informed everyone--I had a feeling they definitely knew what happened or would be the ones who would find it.

Not Navy, just did some technical diving when I was younger. Most likely the signature of the implosion was picked up by the old fixed hydrophone arrays that form the backbone of submarine surveillance. It would have been like a really loud thunderclap as about 20 cubic meters of interior volume (and 5 people) tried to instantaneously squeeze into 0.05 cubic meters (about the space 2/3rds of 1 human usually occupies)… odds are hydrophones were still picking it up hours later and thousands of miles away.

And yeah, they knew pretty quick that a sound consistent with an implosion was heard at a time consistent with the loss of communication… not entirely sure why there wasn’t more communication of that earlier, though. Probably some fairly rich constituents pushing on the political side for a showy (and costly) rescue attempt that was always going to end up being a salvage and recovery operation.

Now that the engineering choices have become clear it’s no wonder this happened… they really had “disrupted” their way into a time bomb.

Cool, thanks! Technical divings, sounds like using gases and specialized stuff. I wonder why you did that, just for fun? Pretty interesting anyway. :)

I was in Vancouver, BC at the time, and all the diving that wasn’t just wading in from shore was technical, due to the depths and the temperatures. So drysuits, nitrox, argon bottles for insulation in the cold, that sort of thing. It’s a fascinating world, but that time I had to do an emergency, no-air ascent from pitch black 110ft down after an o-ring snapped in my regulator kind of told me it wasn’t a life-long hobby.

Wow man, that’s impressive. Kinda makes me want to try it all the more now. Is that crazy?
