re: Titanic tourist submarine goes missing

Didn’t the same thing do it multiple times before?

What does that matter, when each subsequent attempt is less safe than the previous?

If I recall SpaceX moved from using carbon fiber overwrapped pressure vessels to stainless steel simply because it proved too difficult to determine if there were structural flaws in the composite. This would also entail a difficulty in assessing fatigue in these structures, so that’s definitely an issue when you plan on taking multiple trips and placing your vessel under load repeatedly as in the case of this submarine.

But my main gripe is just the fact that the structure wasn’t homogenous. The titanium end caps being adhered to the carbon fiber matrix seems like an obvious point of failure.

It’s honestly surprising this vehicle was legal to operate.

Using previous experience and expertise. Military experience would be good since they “ perfected” submarines.

If you are going to start re-engineering a submarine like you are “ Bubba “ in the shop. You better keep the damn thing in the pond on the Back 40.

One of the passengers was on his 38th trip to Titanic if I recall.

Just when you thought it couldn't get worse.

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

This guy cut every corner to pinch pennies.

When, if ever, will we get pictures of the debris field?

Would be interested to see what vessels were in the area beginning late Sun into mid afternoon Monday.

Vesseltracker has preliminary details but someone above my pay grade could assemble it.

I watched a video earlier from a guy called Sub Brief on YT. He showed stills from a video about the construction of the vessel and he showed how they wove the carbon fiber.

They did not do it in the expected fashion where it was woven in multiple overlapping layers going diagonally across the length of the hull. Instead they wrapped it around like they were rolling up a roll of tape.

Knowing the CEO they probably did it in this fashion to save money and time. He didn't have time to do things correctly, he only had time to get people to give up a quarter of a million of dollars per trip.

Additionally it turns out they once had radio communications on previous missions and tests. The CEO demanded they do away with that because he did not want to be "bothered" with update requests and other items when on his trips. This is why they had such a rudimentary system setup in later missions.

I'm convinced this guy just found a way to get others to pay for his dopamine hit of going down to the depths of the ocean and really cared little about anything else. It wasn't about seeing a historic ship wreck or about pushing the science of deep sea diving further along, it was all about him getting his feel good kick and he got himself and 4 others killed doing it.
