James Cameron says the Titan passengers probably knew the submersible was in trouble
The Titanic director has made 33 dives to the shipwreck and visited ocean depths in a submersible he built himself. He compares OceanGate to the Titanic in that both ignored safety warnings.
Damn, I didn't realize Ja knew so much about materials science.
Apparently he built the sub he used to go to the titanic and into the Mariana trench. Dude must be intimately familiar with this sort of thing with that experience.
He honestly seems like a fairly accomplished and responsible citizen scientist compared to the Oceangate clown (RIP).
Now that you mention it I think Ja Rule filmed one of his music videos in Challenger Deep!
Like, I don't trust carbon fiber for my bicycle frame and stick to steel because that shit cracks easily. I can't believe this guy rolled the dice with carbon fiber on a fucking deep-sea submarine.
Okay, but what does Ja Rule think?
feels like they probably knew that in their heart the moment they see the $30 Logitech controller...
I know the controller seems corny, but it turns out that even the US Navy have used Xbox controllers.
The real red flags here were the carbon fiber hull and the fact that the Titan wasn't even certified or properly tested to ensure it could survive the stress of repeated dives to such extreme depths.
It's kinda insane that OceanGate got away with taking paying tourists down in that thing for as long as they did.
To be fair the Xbox controllers are probably more reliable.
It's a question of quality control. Military grade equipment is not the same as consumer grade equipment. That's why we have grade in the first place.
"Military grade" is not a statement of high-quality... it's a statement of specified minimum capabilities and characteristics to satisfy a contract. It's quite common for off the shelf commercial equipment, even stuff targeted at home consumers, to meet or exceed MIL-STDs.
What do you think quality means? Go pick some IC's and you will see that the best quality is kept for military grade operations like operations in very low temperature for example. An IC designed with a high swing in operational temperature will require much more thinking than a consumer IC.
Thanks for providing an example supporting what I said.
Cool...I'm glad that you understand better what quality means. Now if you have a different definition of quality that's a different story.
At least one of us does.
Yeah, it wasn't the video game controller that failed...
I believe the Navy uses xbox controllers for controlling periscopes, not the entire submarine.
Using a game controller is not that unusual.
but it was wireless, that is bad.
What was the controller commanding btw?
The thrusters on the outside. The goal was to minimize hull penetrations for cabling and things.
Thank you, so the signal went through the water a little bit. We had a struggle about it in a different thread.
Probably not, actually. carbon fiber is opaque to blue tooth. Even a single ply carbon shell is enough to block it. My DLG r/c airplane uses an arramid section for the antenna.
Yeah. It's not unusual, for example:

I’ve heard of this. Out of curiosity (because I don’t actually know), do you know if the controllers used in military applications are literally “off the shelf” or if they’re “Xbox-like”, which is what most descriptions about them say.
In other words, I suspect the military(s) using these type of controllers are not just ordering them off Amazon and using them as-is, whereas it sounds like that’s exactly what OceanGate did.
Glad to see James Cameron weighing in because James Cameron knows the people need James Cameron's opinion
I think if you read the article you’ll find he’s actually an expert in this, on multiple levels. I had no idea previously.
James Cameron's not faking expertise in deep sea diving. He did a solo dive to the deepest-known point on Earth back in 2012.
In a submarine he built himself. Cameron has every right to comment on this event, he's legitimately a subject matter expert.
afaik, he piloted it, he did not build it. He brought cameras.
He was part of the team that designed and built it according to this Science.org article.
And yet not 2 posts up you quote Cameron in a way that makes him sound like he has significant knowledge about the structural integrity and construction of a high pressure tolerant vessel.
I pulled an extract of the article. The extract doesn't say that he built the sub, he is educated on the subject, that's it.
It's not clear what you are trying to say. He obviously funded it and piloted it and had to be intimately involved in its construction, including oversight and planning. He took the thing down to the bottom of the Mariana Trench. Are you arguing that he doesn't know as much about the construction of the sub as a guy welding a joint or tightening a bolt? I'm pretty sure that most people would say that if you could name one person that "built" the sub it would be him. He is arguably the world's expert on this topic.
More than we need some armchair commenter trying to diss someone who's an expert in this field because...?
I mean he is the greatest pioneer!
