sub's hull was made with carbon fiber from Boeing that was past its airplane shelf li

I'm in the hull penetration failed category myself. The way that sub was assembled, the joints and penetrations represent serious weak spots in the hull. At depth, one little leak and you're finished.

I don't see the porthole as that big an issue on its own. Even the bathyscaphe, Trieste had one back in the 60's and it went to the bottom of the Mariana trench.

It worked on the principle of a helium balloon. The big hull was filled with avgas that is lighter than water and incompressible. There were two lead shot tanks and two ballast tanks that you used to keep it at a certain depth. The two-man sphere on the bottom was where things were controlled from. Being a sphere, it was going to be the strongest shape possible.

There's a photo of one of the monitors being bolted directly to the hull lol. This thing was doomed.

Bingo!! You can't just super glue that stuff together and think it was going to hold.

Fiber doesn't give, it starts to deteriorate over a period of time under pressure, it doesn't give, and can fail.

I think the crew heard the thing starting to make noises and they knew something was wrong, and knew they were in trouble, as someone said they deliberately dropped their lowering weights about half-way down. They may have had time for a last prayer.

Had the pressure cabin been one piece- entirely made out of titanium, it would have given a little under that kind of pressure, but without deteriorating or imploding.

But, I like you, think it was in the bonding that failed rather than the fibrous section itself. I think pictures taken by the search sub shows the fibrous middle still in tack with the titanium endcap and the aft tailpiece laying nearby separated from the middle part.

I hope they can raise this thing and prove it though- before someone else thinks they know more about physics than Donald Trump!

What does Donald Trump have to do with it?

That's why we have regulations, capitalism likes to cut corners anywhere it can to reduce cost/maximize profit.

What makes you think politicians are incorruptible saints? ... that never skim, never overcharge, despise nepotism, and don't spend on, or create, engineering failures?

It was cost. Titanium hulls are expensive. Bargain basement carbon fiber from Boeing was cheap. Weight isn't as much of a factor as it is with flight.

OceanGate promoted the Titan’s carbon fiber construction — with titanium endcaps — as “lighter in weight and more efficient to mobilize than other deep diving submersibles” on its website. It also said the vessel was designed to dive four kilometers (2.4 miles) “with a comfortable safety margin,” according to court documents.

For all of you Titaniacs that are dying (OK, that was bad!) to see the Titanic, I found this interesting short film...

That was my argument. You can see more by watching videos than you can by fighting with other passengers to look out of the tiny window.

Well he paid the ultimate price for cutting corners

Yes he did. Like Musk, he was drinking his own piss.

You have to be pretty delusional to go on a dive after cutting corners on a craft that is performing extremely dangerous tasks.

I feel sorry for the kid who died despite not wanting to attend the dive with his father.

Agreed. Just like you don't need to go to Washington, DC, Europe or anywhere else since you can see the entire world online. :thup:

That said, I do not advocate nor support barring people from doing so if they so choose. Same goes for Bunji jumping, mountain climbing, scuba diving, etc.

Yup. Super Bowl too. No better seat than in your own living room.

My buddy wants to go to a UFC event one day. I told him that we have much better seats in the living room, and we don't risk getting into a brawl with rowdy fans.
