If it ruptured at that depth, you'd be dead before you knew it - it would be a quick death, at least. 6,000 psi/410 bar!

Not quick enough. I watched a terrible documentary focused on dead on a submarine. Ususaly when the hull is compromised, the water compresses the air and air kills you.

Did the passengers buy a one way ticket?
I'm claustrophobic, I wouldn't have even gotten in the sub.

I'm fat, I wouldn't have fit in the sub 
Jokes aside, two things spring to mind: a) let's hope they are found before the 96 hours air reserve deadline - loss of life is tragic no matter circumstances; b) just because something can be done it doesn't mean is should be done.

The Titanic is a mile down, odds of survival are not in their favor, but I do hope they come out alive.

More like 2 miles, but after a certain point it doesn't matter.

You're right, don't know where I got 1 mile from.

Me and the missus went on a submarine in Hawaii, around 100-125 ft down. My wife was marveling at the fish and coral we were seeing, me thinking how screwed we'd be if something went wrong.

LOL! It brought to mind a brief conversation I had with tourists standing on the Sky Walk at work. Grand Canyon West Sky Walk is a glass walkway extending out over the edge of the Grand Canyon with a marvelous view of the bottom, some 4000' down. I casually mentioned to the others on the walk, "you do know that this was built by the low bidder, right?" Expressions were priceless... Being crushed in a sub would be a terrible way to die, but it's quick. Falling from that thing you'll have some time to think about it.
I wonder what the guy who jumped last week was thinking about?

Yup. Fell, my hiney. There's all sorts of barriers around it, and people within 50' to help. He either jumped or was pushed.

So he could not have climbed up to 'get a really good selfie' and then leaned too far back? Pictures I found don't really make it clear if there is a catch net around it.
Certainly other people at the Grand Canyon in other places have done exactly that.

They don't allow cell phones on the Walk, and if you want a picture, the staff will take one and sell it to you! It's quite a racket.

Does that go for old style cameras as well? Or do they simply assume that nowadays, photos are made with a telephone?
(So what if an old style camera has phone electronics so you can make a call with your camera?  )

Yes. Nothing in your hands, no purses, packages, or anthing else that might be dropped or hurled over the side. They don't quite strip search, but it's close.

Ah. That makes sense.
Wonder if they do it to protect the Canyon or because they don't want to deal with people yelling about how they 'must get it back'.

Curious question, does anyone know: It is reported that they lost communication with the submarine Sunday afternoon.
What kind of communication technology is used under such conditions?
Sea water sucks up short radio wavelengths like a sponge. Do they use very long wavelength radio waves? (Loran-C, navigation system developed for submarine use, operated around 100 kHz.)
I know laser / optical has been used for underwater communication under some circumstances, but as far as I know, quite different from 3800 meters of depth. Ultrasound has been used as well, but again: Certainly not down to 3800 meters.
If they had cabled connection, which is not uncommon with ROVs, even at such depths, I guess the submarine could have been found by simply following the cable. So that is probably not the answer.
Are there other alternatives?

If cabled, would there be chances that the cable got cut?

Some years ago, an ocean fiber cable was cut over in the outer Oslo fjord, and a couple days later, a swordfish (not regularly seen in Norwegian waters) were caught in the same area. Believe it or not: This is a true story. But the swordfish was never convicted for cutting the cable. (He probably wasn't even sued.)
The cable may of course have been cut, but that would be such an essential point that I am sure it would have been reported in the news. I also would think that a cable designed to run to a depth of 3800 m would be extremely strong, so if cut, some rather dramatic event must have taken place. (My guess only!)

Thanks for the link. It is probably reasonably reliable - but I guess that it takes some fancy encoding and error correction to go almost four kilometers through plankton, currents, microplastics, fish schools ...
I am not sure about the interpretation of "The Titan would have had ...", though. A corresponding wording in Norwegian, "Titan skal ha hatt ..." should be read as "We have heard this as a rumor, but don't nail us if it turns out to be incorrect!" Maybe "would have had" is more reliable

In 2009, we had gone in a sub, to a depth of about 120 feet off the coast of Mauritius. Luckily we came up as planned.

I am reading the book from Itzik on T-SQL about logical query processing. it is really good.
my question is: Is this logical query processing the same for Teradata SQL?

I don't know what, "logical query processing", means.
