USN != USCG. See my other comment in this thread that can explain it well.

That doesn't matter, dude. This is all set up on an ICS model. They're highly coordinated. Turn on your news sometime and one guy, a fire chief, a sheriff, or maybe rarely a military guy will be speaking and it won't be because they rock-paper-scissored for it. I'm the last person to deny the massive frustrating bureaucracy that is the US military, but in this kind of thing, that's not an issue. Former O-4 17 alpha.…

Wouldn't it be possible, if the Navy program were too secret, that they had no counterpart in the Coast Guard cleared for it?

Those who are familiar with US submarine operations would assume this from the start. For an excellent account of the development of US submarine capabilities (including listening and detection), I wholeheartedly recommend the book "Blind Man's Bluff".[0] How that book hasn't been made into a mini-series is beyond me. The stories and characters are incredible. [0] https://www.amazon.com/Blind-Mans-Bluff-Submarine-Esp…

Does this mean the passengers had an instantaneous death?

I believe James Cameron called it being turned into a, "meat cloud." Absolutely occurred in under 30ms (upper bound). Possibly as quick as 2ms, and in all likelihood well under 10ms.

Rough estimates, but at that depth, it’s around 450 atmospheres of pressure, or around 6,500 lbs per square inch. Pretty much instantaneous.

Well heck I just argued with a bunch of people, who said the USN knew but would never tell anyone and me saying it's a baseless claim. I guess we were both wrong.

Well, we've had US intelligence, and specifically SOSUS, make its way to the public before, like with [0] https://en.wikipedia.org/wiki/Vela_incident

Or https://en.wikipedia.org/wiki/SOSUS (article created 2003)

Maybe this is off-topic, but in the midst of so much controversy about "top-secret documents" -- is it actually legal to leak out that such a "top secret military acoustic detection system" even exists, and if so, the results of the system's use? I mean, how is it "top secret" if it's in the newspaper?

It's usually illegal for the person to tell the reporter, but legal for the reporter to repeat what he was told. Notice that the Navy asked (not told) the reporter to withhold certain details.

I can understand that, if the reporter is not aware that the information is secret. But clearly they do know this is a "top secret" system, it's in the headline, so I'd assume the plausible deniability excuse doesn't apply.

It's very common for "technical details" of a system to receive a different classification than the "fact of existence" of said system. In other words, it's widely known that the Navy has a system for listening. The internal designation, capabilities and limits of operation are not widely known and that information should be kept secret. > The Navy asked that the specific system used not be named, citing national sec…

So the name, and internal designation, is "top secret"? You're saying the capabilities are also secret but the newspaper just reported the data it generated, which certainly suggests what its capabilities are.

And why is it "widely known" that the military has this listening system? If it's really "top secret" then no, the public shouldn't know about it. Seems like everything is "top secret" until someone wants to show off all the cool toys.

I'm pretty sure the Navy also knows what was causing the "banging" heard underwater during the search. I don't understand the point of leaking this information now, it just makes it look like the Coast Guard spent 3 days and considerable money pretending to look for a target it knew was probably destroyed.

The cynical part of me thinks everyone involved knew what had happened on Sunday. There was ample evidence that the submersible imploded (repeated stress on a carbon fiber frame, zero regard for safety, the fact that all communication was lost permanently). Then there was the fact that the logistics involved in a rescue were basically insurmountable. The Navy/Coast Guard saw this as a good live training exercise and…

> hopeless and not really worth pursuing

Even a hopeless situation, people still want to see, and possibly recover, the surviving wreckage. The whole point of the original exploration was to view the Titanic wreckage. Various military spent enormous resources looking for MH370 for months/years.

It's not about plausible deniability. They know the information is top secret. They asked the Navy for comment and were probably told that.

The 1st amendment still protects the reporter. They are legally in the clear. The person who told them is not.

Theres an avid discussion on the other thread about this, but the short answer is likely yes. They were probably crushed, incinerated and then bludgeoned to death in less than 3ms, and probably unconscious before they were aware of any of the rest of it.

While the physical trauma would have been instantaneous, they might have known it was going to happen. James Cameron just said in an interview[0] that they had a sensor system inside which detects when the hull is starting to fail, and that they probably had warning because they had dropped their weights to ascend.

Not an expert, but seeing hydrolic press videos using carbon fibre it snaps instantly, also seeing ocean gate videos they don't cross weave the carbon fibre
