One of the distinctive features of this "Titan" deep diving submarine is (or was) the use of carbon fiber and composite materials for the pressure hull. It wasn't entirely made of these kinds of materials. These materials were combined with titanium to construct the pressure hull. This "hybrid" pressure hull construction enabled a lighter weight submarine, which is advantageous.
That's going to be reexamined, for sure.
Edited to add:
I see this also in the previous post from Raydar.[This message has been edited by rinselberg (edited 06-22-2023).]

I believe the sub was built up near Seattle Washington and some that saw it during testing said it looked a bit sketchy even then. Many of the posts I've seen on internet boards are people declaring how dumb the passengers were for wasting so much money to venture down that deep. It's their $$$$$$$$$, they can spend it where they want IMO. The ocean is a dangerous place, even on surface. Much much more so once you descend even a few hundred feet down. You take your hances and it either works ok or it doesn't. [This message has been edited by maryjane (edited 06-22-2023).]

On ABC evening news they had Ballard and James Cameron...Cameron pointed out something I had not actually put together; Arrogance- Both the Titanic sinking and this sub sinking are directly related to the idiotic arrogance of the people responsible for design and manufacture of these two vessels.
The Titanic; This Vessel is absolutely UNSINKABLE!
The submarine; I have used new technology- and noone can tell me I haven't been successful! I don't need anyone checking my work!
You need to be capable of seeing when your "Great Idea" is not perfect...Humility is badly needed- but the hyper successful and hyper rich many times surround themselves with "Yes men" so they only get positive feedback- which causes them to spin out of control....When they eliminate themselves- all well and good...but taking a bunch of innocent souls with them is the real tragedy.

The cost to visit the Titanic in that experimental submersible was $250K. Damn, even before this "incident", I wouldn't have gone down in that thing if I was paid $250K!

Repeated stress to carbon fiber will weaken it. Same happens to fiberglass. You can't see the damage unless you have inspections.
I wouldn't trust this kind of construction without them having to pass inspections after each dive.
I suspect that fatigue cause the submersible to implode.

We'll see what pans out here but if that truly was a 5" thick carbon fiber tube, the pressure at that depth was 6,000 pounds per inch. Carbon fiber that thick can handle WAY more pressure. I have a feeling that the sub imploded end to end and the physical tube is somewhere on the bottom of the ocean. The debris is the landing rack, rear cone, and probably all of the white panels from the sides of the sub. Basically I have a feeling it depressurized exploding all the bodies and causing both ends of the carbon fiber tube to shoot off.
Now, if they are lying about the thickness of the carbon fiber just to "appear safe", then yes, everything is in pieces.[This message has been edited by IMSA GT (edited 06-23-2023).]

Keeping in mind where it was, down very deep and under a helluva lot of pressure... would it have "depressurized"... or would it have been the opposite? I suspect anything and everything inside the sub would be immediately crushed.

I seem to recall the "weak" spot mentioned by experts was the viewing port. I don't believe it was actually rated for the depths that it was being used at with this submersible.[This message has been edited by Patrick (edited 06-23-2023).]

I read today that it's highly unlikely they'll find any remains of the passengers since the implosion is so incredibly violent. It is, for all intents and purposes, pretty much like being strapped to a huge bomb (that explodes). Also that the passengers probably never noticed a thing since it happens in milliseconds.

As Cliff said, the whole event took place in milliseconds. The implosion took around 7 milliseconds. (An involuntary blink of a human eye takes 100-400 milliseconds)
In addition, there was a mixture of oxygen and other gasses in the sub, as well as natural and manmade hydrocarbons that under sudden extreme pressures would self ignite in a violent fashion. Immediately following the implosion, it's very likely an explosion took place and blew parts of the collapsed sub apart. Possibly blowing the fore and aft sections off the main cylinder that formed the sub or splitting open the main compartment. All, in less than a second of elapsed time.
It may have happened earlier than main stream media thinks. Wall Street journal reports the US Navy reported "an anomaly' from one of their Atlantic acoustic sound sensing monitors on Monday and said it would be . It did not elaborate further except to say it was “consistent with an implosion or explosion in the general vicinity of where the Titan submersible was operating when communications were lost”..[This message has been edited by maryjane (edited 06-23-2023).]
