Rush quoted someone saying: "You're known for the rules you break."
He was right. He's famous now.

Funny how neither NASA nor the University of Washington had anything to say about the level of collaboration with Oceangate before the tragedy. But as soon as tragedy struck, they both released statements saying the collaboration was minimal. They had no problem with Stockton name dropping their organizations in every interview before the accident, but afterwards “we had nothing to do with this”

Once the carbon fibers started popping, each pop was further degradation of the hull’s integrity. At that point, it was only a matter of time, and I think Rush knew that (he had too) and was just rolling the dice that he could squeeze in a few more dives. He had no idea how many dives the hull could take, which was something he absolutely needed to know.

[timestampterrysassistant]

Stockton should be a case study, lots to learn.

[Olivershoesoff]

I'm kinda over it at this point....
The carbon-fiber hull is strong in tension...not compression.
An improper use of a material caused a loss of people too unfortunate to know that Stockton Rush was a goddamn fool.
He earned his place in engineering history for others on what NOT to do.

[allbuckwild]

Why do they think comparing flying airplanes and deep sea diving is what makes it safe? Pressure 30, 000 feet in the air is NOT the same as pressure 4000 meters underwater..the pressure difference is astronomical..air gets thinner the higher you go..water is DENSE..but not as dense as stockton rushs attitude I guess

[TheChiefEng]

Any cracking from a carbon fiber matrix is usually a sign that some of the fibers in the matrix are snapping. While a 5 inch thick carbon hull of course will buy a little time when this process starts, the problem is that you never know how the process accelerates so the process could be relatively slow but it could also speed up violently and fail very quickly.
The Titan carbon fiber hull did not seem to have a cross woven carbon fiber matrix which would have made the carbon matrix less strong. Another problem is that the hull was never cured in an autoclave so there is a high likelihood that there may have been some voids in the carbon fiber and binder agent matrix.
Another point of concern is the fact that carbon fiber is very good in tension (stretching force) but not a wonder material to withstand compression forces and especially not compression cycle forces.
It is also problematic to use carbon fiber together with another material such as Titanium since the Titanium transition rings were glued in place. The end caps of the submersible were made of Titanium and since the carbon fiber hull was cylindrical, there would have been very high forces working on the Titanium transition rings due to the pressure transfer coming from the end caps together with the surrounding pressure working on the carbon fiber cylindrical hull.
The Titan was basically a very risky design and virtually no expert in the deep sea exploration industry had anything good to say about the design.

[Hittlinho]

Why am I obsessed of this Titan thing.

[younge]

the emphasis is always on the lack of certification, but the complete disregard of industry standards was the real issue. had they chose more conventional materials and components then they would probably still be alive and operating the sub. i find it very hard to understand how people with an education in engineering designed something so improper when the consequences are so great

[skiprockjr.]

It seems like a couple of Japanese 6th graders could have figured out Titan was going to implode.

[Commander-McBragg]

Funny that everybody wanted to be associated with this project, but after it went bababoom everyone skidaddled.

[CertifiedSupplyChainPro]

It's interesting @ 5:18 he says the hemispheres were carbon fiber, but Titan's were titanium

[kevinashley]

Rush is definitely to blame for his ignorance and ego, but these other companies should be held accountable too. They wanted the credit during success, yet they want nothing to do with the failure.

[Flyingmsdaisy]

Even if the carbon fiber was adequate, the way he joined the titanium rings was lacking. Experts say:
Titanium mating surface should have been acid etched.

There should never had been bare hands touching the mating surfaces prior to glueing. (The video shows a bare handed man wiping it)

Excess adhesive should have been used.

Assembly should have cured under pressure and heat in an autoclave.

NDT inspection of the joints after curing to insure no air and complete attachment.

Stockton didn’t perform a single step of this proven Process.

[sirxanthor]

I'd tell Stockton Rush to not let the door hit him in the ass on the Way out, but basically the door, portal, and ceiling hit him as well.

Thank you for creating this video, EddieGM. It is much more comprehensive compared to most as it clearly demonstrates the affiliation OceanGate had with other agencies & universities. Many of these entities have denied or attempted to lessen any involvement with OceanGate following the loss of the Titan submersible. I like that you show actual statements/releases made and note the date they were made. No other content creators I've seen have addressed this particular element. You have earned a new subscriber. Well done!

Man the video with Stockton saying it’s unsinkable aged like fine, sour milk.

[jdaniel]

There is so much AI-read garbage with the Titan debacle. This is refreshing and very well produced. A+

[torana]

Rush calling Boeing : so how much atmospheric pressure can your carbon fiber handle.
Boeing : it’s a plane so anywhere from zero to one.
Rush : sounds perfect

[HappyMealBieber]

Oceangate would have been fine going in shallow mid dives, The Titanic thing was a terrible idea. And made no sense other than to make quick easy millions. Greed and Massive Ego was to blame here. Also hubris pride and arrogance. All cobbled together like his carbon fiber and Super Glue
