James Cameron, the Oscar-winning director of “Titanic,” said on Thursday that the OceanGates’ Titan submersible that imploded underwater did so because it was not constructed out of the proper materials.
Cameron, who is considered an expert at diving and submersibles, made the remarks during interviews with ABC News and The New York Times after officials announced that they had located the debris of the vessel on the ocean floor and the five passengers on board had all died.

Yes, but our subs go maybe 1,000 feet and Titanic is 12,000.
Nobody has pointed out that submarines as warships were typically meant to be stealth ships. Before nuclear-powered submarines, they would run on the surface and only dive to avoid being detected.
When they dived, they only needed to dive to a depth of about 70 feet in order to raise their periscope. They dove lower than that only to avoid depth charges or find inversion layers in the water.
That was it.
WWII era Gato-class submarines had a maximum depth of around 300 to 400 feet. Later nuclear Los Angeles, Seawolf, Virginia class submarines could dive to 1,500-1,600 feet. These submarines didn't need to go any deeper than that.
Deep-sea exploration submersibles needed to be a different shape, likely spherical so that the pressure is equally distributed across the entire frame (the way that liquified natural gas is stored under high pressure in spherical tanks).

Well, you hit the nail on the head.
There was absolutely no point in this voyage or their loss of life and property, the chaos and expense they caused the military and the public except for bragging rights by a few “great men.”
At least they are shooting African Tigers with a semi automatic combat rifle to show their greatness.
JC is more than just another celebrity spouting off an unsolicited opinion... He does have experience in this. Even when subs are constructed of the right material, implosion can happen. Both the US and the Soviets know this fully well.
There is still a possibility for recovering more remains of Titan, including from the submersible’s shell, [Sal] Mercogliano said. The question is how much of the pressure vessel remains outside of the titanium ends already recovered."
A standard foot of sea water weighs ~0.44444 pounds per square inch.
0.44444 x 12,000 = 5333 psi
With all that’s been revealed thus far, it certainly looks bad for the company.
Rapid compared to what? Water is incompressible so the increase in pressure by depth is uniform.
Thank heaven! If uninspiring white men had been involved the mob would demand their heads.
Still, I don't see why we would make manned military subs that can go to 15,000 feet.

All larger composite structures are "glued" together. That includes the Boeing 787 and Airbus 350 jet airliners.
Glue seems to work for them.
They aren’t at 12000 feet deep and 5000+ psi............
Have they posted pictures/video of the wreckage yet, then?
Rapid compared to regular atmosphere, perhaps?
ok... so I exaggerated a little bit.. theyre still dead by being crushed...
I neither wrote nor implied they either were or ever had been.
Normally I’d agree with you on a Hollywood figure, but Cameron is *actually* an expert - not a leading expert, but he’s got engineering and crew experience on submersibles. Here’s one of the craft he worked on: https://en.wikipedia.org/wiki/Deepsea_Challenger
He got into diving and submersibles in order to advance his filming. One of those “In order to advance my career in one field, I had to become an expert in another” or “I took up a hobby and became an expert in that field” kind of things - kind of like how Paul Newman was an actual expert on motor racing, for example.
Yeah, he was on the Deepsea Challenger team: https://en.wikipedia.org/wiki/Deepsea_Challenger
