Tourist submarine exploring Titanic wreckage disappears in Atlantic Ocean

I’m not seeing a movie here. No hero, no survivors.

There will be a Netflix documentary about the company and its race to put profits over safety. That’s a guarantee.

BBC already has a documentary on the submarine and the rescue attempt. I think it comes out in the next day or two.

LOL your feeble attempts to backtrack are quite indicative of a weak minded person.

Let's revisit the chain of events:

(1) I posted that no video or article that we have seen so far in this thread mention how tilt and trim were controlled on that sub, and if anyone had any information on that.

(2) You replied, 'look at the picture'.

(3) I replied for you to educate me on what in the picture controls tilt and trim since it darn sure is not apparent.

(4) You posted a picture of it with no explanation.

(5) Despite my specific questioning for you (since you are, apparently, the expert given your first response) you lament 'thrusters' and offer nothing but the type of responses that truly ignorant people resort to when they are backed into an intellectual corner from which they do not have the means to escape.

Now, let me help yu to improve your critical thinking skills. The 3 knots is important because that is an indicator of the maneuvering power available. That pig weighed over 21,000 pounds wet and has a pretty good cross-section, as well as a pretty variable COG because the passengers can move forward and back insode. So right off the bat we know that the sub is not exactly a powerhouse and is out of breath with a current - that could be going front to back, side to side, or up and down - of 3 knots.

Next, we see from where the thrusters are located that they only seem effective at the COM. They cannot steer or lift the bow or stern separately. Normally, trim is adjusted by adjustments to the attitude of the bow or stern of a vessel, and tilt by the same for side to side. How do you do that with thrusters located at the middle? Maybe with sliding weights or trim tanks that can be flooded or purged - but we see no evidence of those n the picture, right? Are you with me so far?

Lastly, the joystick controllers seems to operate akin to a POV control n a video game. Move forward or back, up or down, turn right or left. Wonderful. No avatar n a video game is being pushed sideways or downhill. Ergo, no tilt or trim control capability. Which means that if even with super-duper powerful thrusters, and if even with them located where they were was capable of helping with tilt and trim, the operator had no way to independently control the thrusters to counter.

Read the above several times. Carefully. Point to the words with your fingers and move your lips if it helps. Once you get it, then look again at the picture and help me understand how that craft handled tilt and trim adjustments. For bonus points, explain how it could recover from a nose dive.

We'll patiently wait for your response because we know you'll need time to thin it through. Good luck, we're all counting on you.

I’m still not sure why they used carbon fiber in the first place. I didn't finish engineering school, but the industries that use it are primarily because of its low weight vs it’s high initial stiffness. Long term durability and impact resistance aren’t even on the list. People have cracked mountain bike handlebars due to overtightening brake master cylinder clamps with handheld Allen keys, and frames regularly crack and fail.

Why not build the thing out of steel? It really doesn’t matter if it ends up weighing 40k lbs once it’s under water.

Oh come on. Every sub on earth is made of metal. That's such a 50 year old white guy thing.
You need to be different. You need to be inspirational!

Edit: You guys are too good, I see at least 2 others beat me to the punch with this line.

Or I have more important shit to do on a Friday then read the drivel posted by a pseudo intellectual who has too much time on their hands. The bit I skimmed on my way out the door was riddled with bullshit and assumptions, so your verbose response is no better constructed than any of mine.

But you have time to tell us you don't have the time. And at first you wrote that yu would not read it, and now it seems that you have, at least some of it.

Keep at it, boyo, we would love to see you rise from your intellectual abyss.
 
The rest of the lefties and woke need to "get on board"

They really need this inspirational bit in their lives.

bill gates needs a sub like the idiot now living @ 12500 ft below sea level.

Does anybody besides me want to start dumping random junk into the depths now with cameras attached to watch it implode under the pressure?

Yes. :bounce:

I asked earlier for a video of that. I'm sure some company or military has done tests. Find it.

Don't think there was one. At least didn't sign off for it to be used in the manner it was used. Also, what would be the point of litigation? The CEO is dead. The company will jump into bankruptcy. There will be no assets left.

I have read that there is a cofounder who is still alive. All those rich people’s families are gonna want blood. They will make sure everybody involved is poor for the rest of their lives. Heaven help them if there’s any laws that they broke that would lead to jail time. I’m not really up on maritime law’s, so I don’t know what would happen.
 
Dont they give up the right to sue by signing waivers? I have signed several doing sketchy shit, but I always wondered how legit they were.
 
The family of the CEO might be able to be sued if that is where the ceo's money went upon his death.

It makes you wonder about those submarine movies where after they have depth charges go off around them, water starts coming in through plumbing pipes and they frantically shut them down. Is that just Hollywood or reality and if reality, not deep enough pressure to crush the sub?
Click to expand...
I think a typical sub is <500 ft down. Way less pressure.
 
I have only been paying attention to the memes and the 50yr old dudes crying that this was controlled with a video game controller, but did this actually reach the depth of the Titanic or did it implode before then?

Sounds like it happened prior to reaching Titanic since the debris fields were a decent distance apart from each other.



Meanwhile, the opposite of being crushed by depth pressure is decompression from coming up too quick from depths.
Here is what you could end up looking like if you do that:

According to the James Cameron video posted up above, they were still quite a ways away may be only 3500 feet down when the trouble occurred.

If I was building a sub, NASA or Boeing would be waaay down the list of companies to consult :laughing:

Maybe NASA because they have info on exploring planets in our system that have extreme pressures. I'm sure they have some hypothetical engineered vehicles for this.
 
The waivers depend. If everything was solid and by the book, the waivers may hold a bit. If you sign a waiver, and the company or person providing said waivered service acted in a knowingly negligent manner, the waiver is on much shakier ground because what you actually signed for was not in fact that which was delivered.

In my line of reasoning anyway.

Signed a waiver to board an experimental sub to do an inherently dangerous thing is one thing... Signing that same waiver to board an experimental sub that was built with parts not certified for the inherently dangerous thing is something else. One would have a reasonable expectation, in absolving the company of responsibility should something go wrong, that the company is providing an experimental vehicle that is as safe as possible... That was not the case.

I wonder if the waiver has the same strength as a skydiving waiver.🤔

When I flew (not jump) I had to sign a waiver AND be filmed answering the same questions that's on said waiver.

We were told a story in high school from a retired Navy diver.

He was in the decompression chamber and had to poo. Well there are two valves on that bad larry. One for flushing the toilet, and one on the outside of the chamber to empty the black water tank.

Someone left the empty the black water tank open and he went to courtesy flush. It sucked his intestines out through his butthole. He had to carry them to the "help me" button.

That's happened more than once. Luckily it hasn't happened in a long time. Now days the guy under pressure can't reach the flush valve while sitting on the shitter.

Good news is that there wasn't one. Bad news is that there wasn't one.

In one of the Cameron videos, he said they lost all contact around 3k feet descending. So the dead rich folk never got to the Titanic before being smashed. 250k to be lowered into the darkness and killed. Walking into traffic would have been cheaper.

The 3k foot depth is interesting. That thing was fully compromised long before it even left the deck.
