Titanic tourist sub missing

[SpookyFrank]

In the instance in the article, they decompressed, fluids boil and material expands......

In the instance of the sub material implodes or crushes instantly, any air space in the body collapses, blood vessels collapse, I think effectively you end up in a very small crumpled bloody mess.

The pressure at that depth is absurd. If you opened an oxygen cylinder down there, oxygen wouldn't come out. Water would go in.

What would people rather, plane crash or this?

Instant death rather than having the time to ponder it?

I think Voyager 1 is in the order of 21 billion miles from earth and yet it seems that communication is less of a problem than they would be if it were simply sitting on the Ocean floor.That surprised me.

Maybe even comparable to the pressure with which Petcha was clutching his pearls earlier on.

In descending order of ease of communication it goes Voyager 1; submarine on the bottom of the sea; DBS call centre.

Thankfully most of the universe doesn’t suffer from gravity.

Given the human body is mostly water I don't think most of it would compress much. Lungs, for sure.

The range of gravity is, let me see here, ah yes.

Infinity.

If the universe was a trillion times the size and contained only two protons, it would still 'suffer from gravity'.

Your bones contain lots of air spaces. Notably the bones in your face.

This, without a doubt - from person to red cloud in the ocean in an instant without a single second of fear, pain, or anticipation

This is quite a good thread comparing that bit of trash with a well engineered deep sea sub…

Well at 2 hours ish in they would have been halfway down their descent, so probably about 2400 metres, which is 240 atmospheres...... that's a lot of compressing

I remember flying on a plane in the 80s that looked like it was held together with gaffer tape. It will have gone through actual mechanical testing though despite its appearance.

I remember reading an autobiographical book by a woman aviator, Beryl Markham, West With the Night, which detailed some of her flights over parts of Africa that were still uncharted, when she was living in Kenya. I remembered her plane was an Avro Avian. Some time later, I randomly happened to be in the air and space gallery at Manchester Museum of Science and Industry, and I saw one of those biplanes, and it looked a bit like a model aeroplane, cobbled together with balsa wood and the wings covered in canvas. It did look like the kind of thing that was probably held together with gaffer tape at some point. I was impressed previously, but having seen one, I amazed that she'd flown in that tiny flimsy looking thing. She led quite an extraordinary life.

inspired me to buy this.

There was someone on a news programme earlier - a television presenter in the US who had reported on this thing and had been inside it. Apparently there were 18 boltholes, but only 17 went in during his demo because they couldn’t find the 18th, and this Stockton guy said ‘well, it doesn’t really matter, we’ve been down with less than 18 before’. So, the owner was very much a man operating without the full complement.

He is:

2 cans short of a six pack,

A sandwich short of a picnic.

One bolt short of a submersible.

 

[AnnO'Neemus]

I'm not understanding why the craft would have imploded or collapsed when it was designed to withstand pressure of the type it was operating at when it was lost.

The hulls of the two lost US submarines USS Thresher & USS Scorpion collapsed at depths that far exceeded their test depths.

Except it - arguably - apparently wasn't designed to withstand pressure of the type it was operating at. Wasn't the journey down supposed to take two hours, and they lost contact at 1'45"? So... three quarters of the way down.

That viewing porthole/bubble thing was supposedly not rated to go down to the depths of the Titanic, it was only rated to go down to about a third of the depth. Or something like that. Vague recollection. I forget the exact numbers mentioned. But the spec really wasn't designed to withstand it's operational pressures.

If anything, you'd want it the other way round, over-specced, rather than under-specced. He knew it was under-specced - again vague recollections of previous posts or articles read - but he didn't want to test it/didn't want to spend money on higher spec.

 

[AnnO'Neemus]

Because the company didn't create or test very well beyond fag packet maths

Ah, you summarised the situation much more succinctly than I managed to.

Squelch

It was at 3300m when they lost communication. So that's an even more ridiculous amount of compressing.

 

[AnnO'Neemus]

Plane because while the sub is quicker I might leave a body to actually identify in a plane crash

Yeah, I watched that pig in a diving suit video. Not recommended.

Pretty sure there was some panels about her at a museum I’ve been to - maybe the RAF Museum Hendon - not sure

I went to the airship museum thing in Svalbard. Telling the stories of various airship attempts in crossing the north pole related hi jinks. were better designed for the job that this sub was. and this was a century ago

There's a zeppelin museum in Friedrichshafen.

It makes little mention of the company's health and safety record for some reason.

 

[xenon]

Just out of interest, what’s the deepest a diver can go wearing all the gear? pressure suit or whatever it’s called.

 

[xenon]

Speaking of flying vehicles. I’m just listening to a thing about the Manhattan project, operation freshman was mentioned. Fuck gliders.

 

[belboid]

The US Navy detected “an acoustic anomaly consistent with an implosion” shortly after the Titan lost contact with the surface, an official has told CBS News, the BBC's US partner.
The information was relayed to the US Coast Guard, which used it to narrow the radius of its search, the official added.
The banging that was reported earlier is now thought to have been coming from other ships in the area, CBS reports.

In the end, it being painted white probably helped.

I haven't watched it or heard of it before, but I just don't know where to start with that sentence ann
