This tiny submarine 2.4 miles under the sea, visiting the relics of RMS Titanic. Can it be found and the crew saved before the air runs out?

[mustang1]

It's tragic and very sad for the families of those who may have died. Other than that, in the great scheme of things, it's no worse than everyday deaths on the roads. Just more public and newsworthy. I really do hope they have surfaced and are alive but as @HMS_Dave said the chances are less than slim.

I also hope they do surface and come out alive.

I just have to say this, I know it's not nice to say in these circumstances: I think at least one person will come out there and proclaim "I just knew I was going to love, I knew I was not going to die on this day!"

I mean, it is very good to have this attitude of hope, but it seems irksome and cheesy.

But anyway, good luck to the them and the rescue team. I am grateful to live in a society where a lot of money is spent to rescue just a handful of people. Idk if they will get money back through insurance or whatever but I have faith in humanity.

closer to home.. and very sad,.Not a lot of detail, but if this chap had a support boat how the heck did they lose him?

I don't disagree that it seems a bad idea and in fact reading that they are bolted in with no way to open it from the inside strikes me as being beyond madness.

I don’t know whether you could build a hatch that would fit such a small submersible, that could be closed by a human, and the seals stand up to the pressures 4000 metres down.

It does not seem to put them off as there are six more swimmers out there today

You'd be crushed so fast you probabky would feel no pain because you'd be brown bread before your nervous system could react. About 2.5 tons PSI will do that.

Its apparently the equivalent (from the BBC) of having the Empire State Building on top of you. Plus, its bolted from the outside.
I amazed a work colleague the other day when I told her that extreme high pressure water jets can cut steel sheets. All those tiny molecules moving very fast.....

anyone who has jet washed their patio in flip flops would NOT be surprised by this.

This underlines the futility of taking people to places where we can send much more capable machines. As conditions get harsher an ever increasing proportion of the mission complexity becomes devoted to life support, and the scientific payload suffers as a result.

 

[Drago]

But then as the great Adam Steltzner has pointed out, an Elvis could ride an elephant past Perseverance rover and it's highly unlikely they would be noted unless they happened to walk right under a dcmera that just happened to be operating at that exact moment. A human wouldn't miss that.

However, this mission was a jolly and not a scientific enquiry so even having a person there for human awareness snd insight can't be justified by that argument. Measured risk for the advancement of scientific knowledge and human progress is one thing, that level or risk for the purposes of entertainment is quite another.

If there is enough oxygen for 96 hrs with a crew" of 8, how long would the oxygen last if the head count were to be reduced?

Back in the 90s, my other half (of the time) did a cross channel swim. She had a fantastic experience but I thought the safety preparation was a bit lacking- nothing more than wearing glowsticks during hours of darkness.

The observer in the boat needs more than that. Hopefully this swimmer towed a marker buoy.

 

[Pale Rider]

I'm not sure why these guys are getting so much stick, perhaps it's because they are filthy rich.

It's little different to the risky activity of mountaineering.

"Why climb that?"

"Because it's there."

They are responsible for their own lives, so the only irresponsibility would be if someone died trying to rescue them.

Unlikely, since no one appears to have the kit to take a person that deep.

 

[Fab Foodie]

Wouldn’t it be good if the same resources were put into saving the lives of poor and desperate people in peril on the sea, not just billionaires?

I don't recall such a rescue effort (or even concern) being put in for the 75? migrants that drowned off Greece last week....
