Missing Titanic submarine

[Twinklesgolden]

How horrifying that a submarine carrying 5 people has gone missing. Apparently there’s only 96 hours of air on the submarine when it sets off.

The people on board must be terrified!

No I'm not I'm talking about ones that are unmanned I thought it was just manned ones we didn't have

They were all advised to restrict their diet before boarding - so they are likely to have started the trip hungry and a bit dehydrated. If they are still alive, they must really be in a state by now.

With this and the monkey story, the BBC News site is the stuff of nightmares today.

I've avoided the monkeys. I'll not look.

Can someone help me understand this. If they only have 40 hours worth of oxygen on the submarine, how was the event meant to work? Were they meant to hop in the submarine and only be down there for a handful of hours or something?

Tragic situation but I can’t quite understand how it was meant to work anyway!

It's supposed to be an 8 hour round trip. Presumably multiple dives if conditions allow.

@ItsBritneyBitchhhh yes that's right. Two hours to reach the bottom and two hours back up again. 4'hours to view the titanic etc

Entire trip 8 hours

So theoretically, plenty of oxygen

@ItsBritneyBitchhhh and they had approximately 96 hours of oxygen to start off with.

They were meant to be down 8-10 hours. The submersible is carried on a ship to the drop site. They hang around on the surface waiting for the right conditions. Then they get in the sub and launch it.

It takes 2 hours to go down. They spend a few hours sight-seeing. Then two hours up again.

They carried 96 hours work of oxygen, of which it is estimated 40 are left. But likely little or no water so, even if plenty of oxygen remains, the people on board will be deteriorating rapidly due to dehydration. Assuming the sub is still intact, of course.

So theres an ROV deployed at the site with a camera the BBC says. So I'm guessing they are just looking for it to confirm they can't do anything about it then? That's sad.

It reminds me very much of the rescue mission of the Chilean miners about a decade or so ago, with the media’s constant obsession with how much oxygen they have left on board. Hoping for a positive outcome!

Thank you all for the quick responses. That sounds so terrible my God. So everyone on board must know that there’s an issue as they should have been back by now?

And is it that the submarine has completely disappeared/gone off radar? Or do search teams know where they are but they can’t be reached?

They have no idea where the vessel is @ItsBritneyBitchhhh

.

@ItsBritneyBitchhhh the sub transmits a communication back to the mothership every 15 minutes usually. They have heard nothing since 1 hour 45 mins into the dive

And they just don't know where it is. The titanic wreck is spread over two miles or so and there's a lot of wreckage down there

Some experts believe it could have hit something down there and possibly not even be intact

Thank you so much for taking the time to explain, I’m sure the same question has been asked multiple times already. How fucking awful that is for everyone on board and their families. The worry and stress must be out of this world

Why did they need to restrict their diet before boarding?

To limit people needing to poo in the tiny toilet. And possibly in case of travel sickness.

Why did they need to restrict their diet before boarding?

There is a toilet (of sorts) on board behind a small curtain. "The pilot turns up the music" if you need to go - to disguise the sounds. However, guest were advised to restrict their diet before boarding to reduce the chances of needing the loo.

If it had hit something which caused damage, how would they have been able to send a distress signal? Wouldn’t they have just imploded? I don’t know how these things work - are they sent manually or is it automatic if the computer detects a problem?

if they could not find the plane mh370 when it went down, they stand next to no chance of finding the sub. It cannot navigate by itself, it needs the mothership. Suspect it has either lost power (& no lights will make it invisible) or had a catastrophic failure and disintegrated.

Yes it’s very likely they could have just been crushed by the pressure if the sub was compromised. It’s thought now they tried to send distress signal possibly but it’s hard to tell which sounds are coming through the ocean are genuine distress codes

@TokyoStories I was watching some titanic / scientist expert earlier and he was saying it's just not capable of doing much at all really. There's no high tech communication in it and his theory was it had hit something and become badly damaged

Which is just terrifying

I haven't RTWT but there's a Times article on this that is very sobering, the craft is described as 'unsophisticated and improvised with off the shelf components' with reports of it becoming lost on a trip last summer and sometimes not having any methods of communication, "all three systems might go down, lights might flicker, the battery might become low".

What a dreadful situation for the poor people on board and their families.

What a massive risk to take.

@ItsBritneyBitchhhh I to just awful isn't it?

I'd not really thought about this sort of 'tourism' before tbh and I think it's possibly a bridge too far

One of the guys in there has been to the moon, the North Pole and the Mariana Trench - the deepest part of the ocean - so he's clearly the very definition of an explorer

But .. just because you can - does not mean you should?

Dunno

did anyone hear the speaker on radio 4 and 17.45?
fascinating.
although he was clearly very worried about the current situation
