Titanic tourist sub goes missing sparking search

[Angelo Farina]

Were the oxygen cylinders being carried in the crew compartment, maybe under the floor?
That would make a considerable difference in any combustion event

Not really.
Only the stechiometric quantity of oxygen reacts with the combustible. And the air inside the shell was possibly already enough for this.
All the excess oxygen just contributes to the gas expansion, but does react chemically.

OceanGate CEO once said Titan sub's hull was made with carbon fiber from Boeing that was past its airplane shelf life, would-be passenger says

Arnie Weissmann said OceanGate CEO Stockton Rush told him he sourced the Titan's carbon fiber, which was too old "for use in airplanes," from Boeing.

As if it wasn’t bad enough that he used carbon fiber now someone is saying that the material was bought at a discount from Boeing because the use by date had come and gone? WTF was this guy and his enablers thinking?

His trust fund, his rules.

Hmm not sure that is true after all - this was rumored originally but (at least according to wiki), Boeing has since denied selling him carbon fiber (or rather claimed they have no record...)

According to Rush, the carbon fiber materials had belonged to Boeing, but OceanGate had purchased them at a significant discount because they were past their shelf-life.[52] Boeing stated they had no record showing they sold carbon fiber to OceanGate or Rush.[53]

Well, either way, sounds sketchy and makes one wonder where the heck did he get it in a first place.

Would the scan of the carbon fiber have picked up the screw holes where they screwed the monitor into the hull?

Probably from Wiki

So this brings up a question - how many full-depth test dives were conducted before the repair/replacement of the carbon-fiber hull? From Wikipedia it sounds like they did 13 dives on Titanic afterwards (not sure if those were all dives that made it to the wreck or if they count aborted dives). If the hull showed significant fatigue after a limited number of dives, that should have been a giant red flag.

I think that we can all agree that there are too many guesses, assumptions, opinions, feelings, hunches, hearsay, second hand intel, 5 years old information, Wikipedia stuff (since when is it considered flawless) and very few proven and updated facts around here to really determine what happened. Only the investigation from the Canadian authorities will give us that.

Look more closely at the picture of the meme.

It appears to be screwed into the insulation behind the perforated sheet that holds the insulation in place.
