I honestly do not understand how this has anything to do with migrant boats. Incidentally 5 young people (between 18 and 30) tragically lost their lives just outside my city a few months ago. Should people feel ashamed that they didn't have threads and newspaper articles about them? Or would some of you here have cheered if I did open one because 4 of them sat in a m2?
Titanic tourist submersible missing | Sub's debris found - crew "have been lost"

Again, you're not going to see posts mocking the migrants for the points I put out, you've ignored.
I honestly and sincerely don't think you've read or understood what I've written.
I haven't moralised, I'm pointing out the people who are.
There is no tether.
I imagine there is a small port hole but at that depth it's just another failure point.
Well in that case....
There is no light at that depth and there is no one else down there to see them even if there was.
They can here banging from the surface or even from a plane with the right equipment.

Yep.
Locating it and recovering it in time will be incredibly difficult even if there are submersibles or ROV's that can go that deep and are equipped to help.
Proof of life
Banging in the area of a missing Sub is most likely the missing the sub
it means at this stage it’s still a rescue and not a recovery
this is incredibly significant
Although it’s still not easy too locate something so small in the pitch black so far down in the ocean, better still bring it back too the surface in the manor these devices require resurfacing because of the pressure, it’s a slow process, if they bring it straight back up too the surface double quick then it could still be catastrophic for all on board
People are getting confused between the human cost and the overall story.
I have far more sympathy for the people involved in the migrant boat tragedy.
Im far more interested in billionaires trapped in a dumb submarine.
I believe they maintain surface pressure inside the submersible so bringing it up fast will just quickly reduce stresses on the submersible and they won't get the bends because they haven't been breathing air at high partial pressures.
If pressure has risen inside the vessel somehow they are probably screwed even if they are located in time.
I guess one positive is if the pressure had risen down there it's hardly imaginable it would have just increased by enough to stress them but not destroy the craft (at least I can't imagine anything).
Did you see the tweet I posted from the woman submariner? She said she couldn't see a CO2 scrubber onboard, I imagine this is what will kill them unfortunately
If the pressure has increased by much they will need to be brought to the surface very slowly or they will die from the bends and they don't have must air left, so no good news I'm afraid.
He's apparently got a history of threatening to shoot up a festival for being called on being a creep by women and harassing others online. I've very little sympathy for him.

The CEO is going to be sued to death if he does survive.
Its not guaranteed. They will have a greater chance being yanked out and flown to a pressurization chamber than being stuck at the bottom of the ocean
I read that they have CO2 scrubbers. When these have absorbed as much CO2 as they can they have emergency scrubber strips and scuba air tanks to extend the time they can survive. I assume all of these will soon be exhausted.
By who? His fellow survivors?
So they have to be located first which seems to be like looking for a needle in a haystack and then they need to be pulled to the surface - if they even can attach something to the submersible and if they even are still somewhere around the Titanic anyway.
If they're not dead already they basically are in practice imo, those are not favorable odds.

In that case, what was the point of going down there in this shoddy tin can?
Yes and/or their families. What am I missing here?
Doubtful they would survive long enough. Their blood would likely "boil" with nitrogen bubbles given how long they would have been breathing air at higher than surface pressure.
The Titan submersible will have lights so you can see the wreck through the observation port.
Ah, fair enough. Feck him in that case.
Detecting a vessel underwater is dependent on 3 key things - the size of the object, the speed it is moving and the noises it makes. As this is a tiny metal tube it has hardly any sonar "footprint" - Think like how much harder it is for a small plane to be picked up by radar.
It is also probably just drifting in a subsea current, so it is not displacing an obvious trail of water that can be detected either - again you can see a contrail from a plane when it is moving at speed / altitude. So the only thing the crew can do is make a non-natural noise at regular intervals, and hope this is detected from multiple locations so they can triangulate position and find them.
This however will take a while as sound travels very far in the ocean - so they will have to gradually vector in on the signal. The more vessels they have looking, with better equipment, the more chance they have of being found in time. I'd expect the Navy will now get involved as they actually have something to go on, rather than just standard search patterns.
It's interesting that they fired the person who seems to be the only one with any Marine engineering experience who raised multiple complaints, wrote a written report saying it was unsafe (which is clearly career suicide for him to have done that in a small company) and then forced him to sign an NDA as part of an out of court settlement....all very reassuring!
Ah ok. So is it the case that the light won't travel very far at that depth so as to aid them being spotted or it's just such a needle in a haystack situation you'd have to be incredibly lucky to get close enough to them?
What I meant is that if a pressured container would fail at any significant depth it wouldn't fail for very long. This isn't a pressurized aircraft hull with exchange with the outside, it's either a sealed container or it's not... and if it's not nothing will help them.
From the clip posted a few times showing some details of this thing, everyone who gets into it signs an “I know this it a shit tin can and I might die” waiver.
They're all billionaires... I think it's more likely they let bygones be bygones
The more I read this thread about how many different ways they could die/have died, the more I wonder why anyone would ever getting on submarine for leisure.
Sure I read there was some Canadian ship going there with the equipment to do something about this?
Probably unlikely but there could be a slow leak.
Fingers crossed.
I'd guess that if their lights were operational it might help locate them if a rescue vessel was very close.
Weird thread really
Wouldn't any sort of imperfections just be crushed instantaneously? Could you have a slow leak at such high pressures?

A hyperbaric chamber?
Do subs not carry ballast they can dump to surface in a hurry, I am sure I read this one did so surely they would have done that if they could have or am I completely off base
I'm starting to think that the sea is a hostile environment for humans.
Screw you, Sebastian! It's most certainly not better down where it's wetter!
In most subs as the pressure increases you may get some internal piping failing first, leading to air leaks/ water leaks etc, but this vessel seemed to have very little stuff on the inside to break. According to the Lochridge guy the viewing glass wasn't properly rated for the depths they were using, so that might be a potential point of failure, but essentially that forms part of the main pressure hull. The ends of this vessel seem to be made from Titanium which may offer some indication of an impending failure but the main body is made of Carbon fibre / composite apparently - so that would potentially just go with a bang.
Once the pressure hull is compromised at those sort of depths - the physics gets horrendous about what happens to the air inside and the pressure wave hitting before the vessel itself implodes. That is the stuff of nightmares!
