Tourist submersible visting the Titanic is missing 101

They likely heard it go 'pop' or whatever sound it made, but for security reasons couldn't tell anyone.

I am sure that the Navy passed the info though the proper channels.
Who in the field got the message is another issue.

P.E. Metallurgy, consulting work welcomed
 
An engineer just told me the sound the sub made was MOOB... an imploding BOOM. [tongue]

The military might not want to let anyone know how good their hearing is...

It sounds like they did tell the unified SAR command early on. The thing is, even the sound on their super-secret listening network would be inconclusive. I.e. it still couldn't be said for certain that it was this sub imploding. In the SAR world, you keep searching while there's still a chance of a successful rescue (even if it's a slim chance). Until either too much time had passed for any reasonable chance of survival, or more definitive wreckage was located, they had to keep treating it as a rescue.
 
Even if the coast guard commander got the info, the report would have been fairly vague - "possible collapse noise in vicinity at xx:xx time" - but you (the CG) still need to search and verify, and there is no point broadcasting that information if you want your search teams to do their job effectively.
 
It'll be interesting to me to see if a full investigation gets performed of this. I'm not sure under what circumstances that happens, given an experimental one-off craft in international waters. Just retrieving bits of it is inordinately expensive, compared to, say, an airplane crash.

On the silliness-factor above- that's bound to come. And one of the issues they look at in these kind of investigations is corporate attitudes and culture.
However, so far, there's just been a whole lot of rehashing of a limited amount of information, so a lot of things get blown out of proportion. Another example is that video game controller, which, it appears, had zero to do with the incident.

The people at the surface might have been aware that the sub had potentially (or even "probably") imploded very early on. But either it did or it didn't, and they couldn't just give up and go home because "maybe it imploded". If it did, there was nothing they could to do help anyone, and if not, time was of the essence, so they proceeded accordingly. I suspect the surface searches were also looking for debris as well as the whole sub. Come to think of it, why didn't those foam floats rise to the surface? And what kind of foam can you even use for that pressure?
 
I was always curious, maybe suspicious, that the Navy didn't record any acoustic event associated with the MH 370 disappearance.
The SOSUS system was good enough in the 60s that they were able to locate at least 2 lost submarines using it, and I'm sure that capability is much better today.
I'm not a conspiracy theorist, BTW.[bigglasses]
If an airliner impacted the surface at several hundred MPH then it would certainly create an acoustic event that should be detectable from a great distance. It should be a much larger event than this small submersible implosion, I think.
Either the navy has no capability in the area, maybe that type of acoustic signature is different enough to become indistinct from background noise, or maybe they did detect it but can't report it for reasons of secrecy of their capability (I think that's unlikely).

The more you know, the more you know you don't know.
 
The listening network is extremely developed in the Atlantic.

"we can hear a whale fart and triangulate in under 30mins" was how it was described to me years ago.

The pacific they never had the need to develop such a network.

There is also something to do with the thermal incline and if your above it or below it. It bounces soundwaves. So things happening on the surface don't get down to the bottom sensors which is the reason why they still use air sub hunters dropping buoys. And stuff below it can be heard the other side of the Atlantic.

Where MH370 headed off towards a lot of the charts are still Cook's era. And that's part of the conspiracy. Basically its a hole in ground based primary detection assets. And calling it a hole is a bit of an understatement its whole percentage numbers of the earths surface. And it would have produced noise above the thermal incline so it would have relative short range. But that also presumes it hit the water hard. But who knows what happened, a water ditching wouldn't have produced much noise.

 
It was operating from a Canadian mothership, and departed from a Canadian port. Both of those are significant factors in maritime jurisdiction. The flag of the mothership, in particular, pretty much trumps everything else in international waters.
 
@boofi,
That reddit thread has a lot of speculative nonsense.
And the video doesn't present anything that wasn't known 40+ years ago.
Supposedly the Titan cylinder was designed to a factor of safety of 2.5, so the cyclic loads should have been nowhere near levels that would cause significant damage; though I have my doubts about how they sized the cylinder for the static loads based on what is in the Compositesworld article linked above, so they could have been very optimistic for static strength leading to having a cyclic loads problem.
Then there is the "bonding" .....

 
Think SOSUS was only North Atlantic?

Maybe Northern Pacific?

Not Southern Ocean.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

The best known sosus is an array that stretches from UK Faroes Greenland down to Barbados.

They will have something up in Alaska listening to what goes into the Pacific from the north east of Russia.

It's a bit like the radar stations watching East.

My generation treat them as general knowledge. The youngsters these days don't have a clue about them.

It's like the big radar head on ST Kilda. Never seen in any pictures but it's there.
 
Thought all those DEW line radars were replaced by satellite IR launch detection platforms.

--Einstein gave the same test to students every year. When asked why he would do something like that, "Because the answers had changed."
 
Having 5 layers material bonded together is good for some applications like bullet proof vests. It's a poor choice for something that has to hold liquid at extreme pressures. Once the water gets in between layers and starts distributing pressure to the inner layers it's going to undergo a progressive delamination. I read somewhere that epoxies have rather poor peel strength. That would have been a disaster once the inner shell started to bulge inward with the outer shell holding in place.

Edit: Never mind, it was 5 inches not layers. But they did layer the carbon fiber so the point may still be valid.
 
The ST Kilda radar also does the Missile range tracking in Benbecular.

There is another one up in Shetland I think that does the Bears coming in from the North.
And the big one down near Leeds.

They are dotted about.
