Titanic tourist submersible missing.

Not sounding to good, even if they get it how long to bring up, just wondering can they supply air to it from outside.
 
Any airline would be crushed by depth, Trev. I would say the only chance is to source sub using ROV and getting a line attached to raise the sub. I doubt there is a rover out there with an umbilical capable to reach such a depth?

Trev, although a few decades ago, this was the difficulty and logistical challenge to rescue Pisces III from 500 Metre depth.

Pisces III submersible: A dramatic underwater rescue - BBC News

Fifty years ago two Britons spent three days trapped in a submersible at the bottom of the seabed while a dramatic rescue operation was under way.

But this is 3800 mtrs depth. There is a submersible in the area now searching for it according to the lunch news, but it stopped communicating around an hour after it started decent. If there was a problem at half the depth and they were alive at that time, the first thing they would do is release the weights. That would have brought them back to the surface.

Either they didn't know there was a problem (unlikely because they should have got a reply from the surface to the regular texts) or as I suspect, there was a problem with the craft. Problems could be with the weight release or implosion/explosion. Pressure on the outside of the hull would have been 148 atm (atmospheres) or 150 bar. One faulty part and that could have failed.

At full depth the pressure would be around 376 atm or 381 bar. So if decent had continued after a fault occurred with the weights, they have no way of getting back to the surface. If they don't survive, I hope it is mercifully quick.

Obviously conjecture at this time, unless a catastrophic implosion (although you would think surface mother vessel sonar would pick this up? ) I'm of thought clump weight release mechanism failure. If this is the end of those souls aboard, I too, hope it is mercifully quick.
 
They could be bobbing about on the surface somewhere but only the top would be visible and it is in a vast, remote area.

Unfortunately the sealed hatch is bolted from the outside and they would have no way of breaking out or getting air so either way they need to be found quickly.

This morning news stating banging noises picked up via sonar. So a glimmer of hope still there.

Re: bobbing on the surface, I doubt an EPIRB would be fitted as it would be crushed by depth, there are some really advanced ROV’s out there now, fingers crossed a Rover will find the sun very soon!

One point I have found hard to get my head around is, a father and son onboard at same time…Hmmmmmm.
 
According to the midday news they believe it is sitting on the sea bed. :(

Horrendous, hanging onto any glimmer of hope, with the underlying thought your time is up, soon!

I hope the sub imploded, death would be instant. 😞
 
It takes a lot of time to winch up as ot must stop many times from that depth, even if found the air inside will not be able to hold to they get it up.
Its a one in a million chance of all being saved, very sad.

Sadly you are right Terry. Hypothermia would also be a better option.

Hopefully a miracle now.

Trev, no stops required as those within are at 1 bar pressure, they can climb out as quickly as they went in.

I haven’t heard much of the search at all today. Apart from sub not fit for purpose, and an ex company whistle blower condemning the sub in design etc. the chit now hitting the fan. I hope there is a secret stash of five tablets to painlessly put them to sleep, if they are not already so?
 
On reading most of what is out there I cannot believe how unregulated this mini sub was how on earth did they get away with that in this day and age, so sad and it’s not looking good now.
 
Some damning reports from submersible experts on this morning news, basically reads like this was a suicide mission, and why a father and son were on same trip beggars belief. A 19 year old Glasgow Uni student, what a waste. James Cameron and other industry regularity bodies wrote to OceanGate with their design and other factors concerns 2018, obviously ignored. Too much money and no sense, who in their right mind would sign their life away, re; contracts signed prior to descent.

An on land vacuum induced implosion.
