Submersible wreckage brought to surface.

This seems to be the consensus among some experts. If there was only one vessel making the voyages, then Titan had made 13 previous trips to the Titanic: 6 in 2021 and 7 in 2022. This ill-fated trip was the first for this year, No. 14. It was probably one too many compression cycles, leading to catastrophic failure.

Carbon fiber is not the wonder material some people seem to think it is. It is not that good in shear or compression compared with many metals. When it fails, it does so without warning. It also does not weather well (was the Titan stored outside when not in use?) and eventually causes corrosion in metal in contact with it. None of that is good in this application either.

You also have to consider the properties, strength, and adhesion of whatever resins and glues are used to fabricate it, which are topics I seldom see discussed when people praise carbon fiber.

I would be concerned with possible voids in the carbon fiber layers. Voids and compression/decompression cycles.

Was it this one:

Florida's iconic 'dome home' built to survive hurricanes is destroyed

The final blow: How the legendary landmark 'dome home' in Cape Romano, Florida that was originally built to withstand deadly storm surges succumbed to Hurricane Ian

This is the "UFO" house on Pensacola Beach. It has been there since the 1970's and has survived every hurricane to hit the beach, including Ivan. The bottom structure has flooded but the top has survived unscathed.

This guy was an arrogant, condescending jerk. (Rush). When one of his own engineers severely questioned the safety of his design, he fired him on the spot, and gave him 10 minutes to gather his things and vacate the building.

He hired based on diversity. Not based on knowledge, and the best qualifications for the job. He was repeatedly warned by other people with far more experience than him in deep submergence, that he was making too many shortcuts, and taking unnecessary and dangerous chances.

He was also told by engineers with far more experience than himself, that carbon fiber was NOT sound material to be used in this application. And that by using it, he was placing himself, and his paying customers in a very compromising position that risked their, and his own safety.

He ignored most everyone who told him anything he didn't want to hear. Now he's dead because of both his stubbornness and arrogance. He got what he set himself up for.

I have some sympathy for the others. In spite of the fact they should have known better. There were a lot of people making plenty of noise about this guy, and his methods.

There was a lawsuit from former employee(s) that tried to alert him of engineering problems and safety issues.

It seems the white male CEO of OceanGate also thought he could be chief engineer as well...

Indeed, no context on the left picture and no mention of a young aspiring female who led the programming team for the lunar landers either.

my favorite part:

The state-of-the-art vessel, designed and engineered by OceanGate Inc. in collaboration experts from NASA, Boeing and the University of Washington, made its subsea debut in 2018. Through the innovative use of modern materials, Titan is lighter, more spacious, and more comfortable than any other deep-diving submersible exploring the ocean today.

Yeah. CF uses epoxy, both in the layering process and in the metal-to-CF joining process.

And now I read that some people are outraged because Netflix is bringing back the movie Titanic on July 1st. Grow up!

The real thing that’s outrageous is the entire OceanGate operation.

Should show Titanic 2 and a retrospective on this tragedy
