Yes we know they're billionaires
We can discuss things that are horrifying and ghoulish, thanks for your opinion.
Migrant boats are sad too

As you were 😁

Regarding the noises picked up by sonar:

"We don't know what they are, to be frank with you," said US Coast Guard Captain Jamie Frederick. "We have to remain optimistic and hopeful."

Thanks Alligator

Heartbreakingly sad. I really hoped when I woke up this morning there would be good news.

I hope they can be found so at least their families have closure.

So many questions need to be asked over the coming weeks. It’s even a huge question of whether they ever will be found as well.

Absolutely this. Its exceptionally expensive and time intensive to develop new tech such as this, realistically there isn't an appetite or a drive for it as not many people at all dive that deep into the ocean. As fascinating as science is innovation is still directed by funding and this is often the more gucci projects and endeavours rather than practical. The sonar they allegedly use to communicate between the polar prince and the sub often cuts out for periods of time; it did on the BBC documentary and that's the only way they know where they're going as they tell them where to go.

@waterlego
the French navel officer has been down 37 times, apparently.
A friend of Hamish Harding was due to join him, but he cancelled shortly before the trip due to his reservations about the safety of Titan. Thank God.

Yes, this - there just aren't enough 'lost in deep sea' incidents for it to be cost effective.

It’s absolutely heartbreaking slowly running out of air I just couldn’t imagine it.

Some friends of Nargeolet are quoted as saying he was ‘reluctant’ to go down on the Titan. The only sources I can find are a couple of articles in French from websites I don’t recognise so I have no idea of their veracity. https://www.varmatin.com/faits-divers/-monsieur-titanic-etait-un-amoureux-des-epaves-varoises-855916

And yes, I expect the friend of Hamish Harding is feeling great relief that he decided not to go, but also presumably devastated at his friend’s fate.

I am hoping against hope the men in the submersible can be recovered alive but I am balancing that against the need to be realistic.

My sympathies to the families of the men aboard the Titan. Not knowing must be agony.

Communications with nuclear submarines at depth is actually difficult and slow - the VLF systems use a very long towed aerial behind a submarine and the shoreside masts and aerials are huge (rugby was used for this). Even this only work to about 30m and is receive only. It's why submarines often have to come up a depth where their comms masts can come up out of the water to connect rapidly to military satellites and the UK's submarines on nuclear deterrent duties has written orders and pre-planned attack scenarios as the chance of zero comms is high.

It is almost ironic, the Titanic in part sank due to short cuts taken in the build and fit out, some argue were deliberately overlooked by those in charge. This submersible has sank, seemingly in part to due to short cuts taken in the build and fit out, arguable deliberately overlooked by those in charge. In both cases the paying passengers not fully appraised of the risks they were facing.

I hope this vessel is found soon, I fear it will lead to endless expeditions to try and find it putting others at risk.

True, obviously it's the first submersible lost at the Titanic site we've heard of but surely underwater tracking tech could be uses for a variety of sub marine purposes.

All sadly a waste of time really thinking about it, just something that doesn't work underwater when we have deep sea cables, under sea bed tunnels, submarines, Navies etc etc all seems a bit unsatisfactory to say the least.

I really pray they can be found. It's very crappy to read some people dehumanising them and saying they are not worthy of rescue but only migrants in boats are. What a world and it's always the 'be kind' crew.

Praying for them, please let all of this line up just in time for them. Please save their souls.

But I don't think we really have any of that at this depth. It genuinely is another world, right in the middle of the ocean, miles from land and under thousands of metres of water.

Navy submarines don't go anywhere near this depth, under sea bed tunnels are only under relatively short stretches of much shallower sea and the cross atlantic cables are probably dropped from much nearer the surface rather than placed on the sea bed by a manned vessel at the same depth.

According to the Guardian:

The co-founder of OceanGate, the company that operates the missing sub, has broken his silence to say he believes the five crew members on board Titan have “longer than what most people think”.
Guillermo Sohnlein, who founded OceanGate with Stockton Rush, one of the passengers aboard the Titan, said he last spoke to Rush a couple of weeks before the expedition’s launch.
In a statement to Insider, Sohnlein, who is no longer involved with the company but remains a minority shareholder, said:
Today will be a critical day in this search and rescue mission, as the sub’s life support supplies are starting to run low.

I’m certain that Stockton and the rest of the crew realized days ago that the best thing they can do to ensure their rescue is to extend the limits of those supplies by relaxing as much as possible. I firmly believe that the time window available for their rescue is longer than what most people think. I continue to hold out hope for my friend and the rest of the crew.He said he encouraged everyone to “remain hopeful” for getting the missing sub back safely and that he continued to “hold out hope” for his friend and the rest of the crew.

RAF flight RRR6894 has taken off from Lossiemouth in Scotland. Boeing C17A Globemaster. According to the BBC it is taking equipment.

I haven't read all the threads but surely those people would be arguing the migrants are equally worthy of just as much efforts to save them as is being done here.

I really can't imagine anyone arguing the people on Titan should be left to die because of how much money they have.

Well I can't anyway.

Even an ROV, it would surely be able to see if something happened to the sub, implosion, getting stuck and then raise the alarm, knowing at least a rough location. Better than waiting 8 hours and then thinking it's probably not coming back up.

The cables at deeper depths are laid on the seabed - or over what ever is on the seabed - with computer guidance controlling the laying

What supplies, @tortoishelll ? The father couldn’t very well hand over his share of the oxygen.

The military spends billions/millions on comms; including (ironically in this case) the ability to go 'dark' and not be detected. All countries have an interest in certain underwater activities not being able to be monitored. If just ourselves had nuclear subs roving around then I'm sure others would be clamouring and chucking money at creating this capability, but most are in the same boat (excuse the pun as it were) and so don't.

Speaking of laying sea cables, I read about these two a few days ago:

Rescue of Roger Mallinson and Roger Chapman - Wikipedia

They were surrounded by thousands of dolphins during their ordeal, who only left once they saw they were safely rescured.

It's pretty clear quite basic safety was side stepped here let alone having an additional layer!
