The Missing Submersible

[breadstick]

If the sub is not found in time will the operation continue to find the sub and the remains of those on board or will it be scaled down, I recall a caver trapped in a cave who couldn't be rescued and his body was left

[Toorak]

The news is suggesting that it imploded at the seabed rather than float to the surface

[retrocop]

//It is essential IMHO that in emergency it should be possible to escape from the inside.//

Agreed and equipped with portable EPIRBs. (Electronic Positioning Indicator Beacons). Not that expensive and standard kit for leisure craft skippers on their boats, particularly the life rafts.

[retrocop]

If the craft imploded 90 minutes into its descent then no internal means of opening the door would of been any use, neither, EPIRBS.
Probably didn't even hear the pressure hull cracking. Just like a grenade going off. Instantaneous implosion.

[lankeela]

Maybe they can't open them from inside to stop anyone panicking and trying to get out and thus killing everyone on board. Surely would be human nature to try to escape if you thought you were going to die in there.

//It is essential IMHO that in emergency it should be possible to escape from the inside.//

it doesnt matter. There was no design checking, no licensing, no passing of tests, safety tests etc

this is all un-licensed ( 'experimental') so I wonder if the deceased have any case against the owners of the sub ( volenti no fit injuria). They accepted the risk - whether or not they signed (useless ) waivers.

whistle blowers are queuing up to say - we told them so

[Peter Pedant]

the fail-safe here ( float to the top in an emerg) failed.
This means that fail-safes cant always work. (ever)

Turing was the first to say that (Halting Problem)

(1000 ABers ask: who Turing den? did he mis-spell Turning? and who HE?)

[naomi24]

Even if the sub could be opened from the inside the enormous pressure at that depth would mean instant death.

[Peter Pedant]

ten times the depth of the last deepest rescue

[naomi24]

I wonder if the 'signals' they thought they were hearing have stopped? If they have, it means it's possible they really were signals and not just wreckage from the Titanic banging around - and that might give some indication of when the craft finally met its fate.

Just a thought... but rather than just knock at intervals, wouldn't it be wiser to use a short Morse Code signal? At least that way the source of the signal could be guaranteed.

I think recovery attempts should stop now unless they are using unmanned craft/equipment. It is just too much of a risk.

[naomi24]

barry, they're using only unmanned equipment.

I read this morning that the earlier signals picked up by RCAF aircraft were signature analysed and found to come from another vessel in the search grid

[retrocop]

Turing invented the bombes that decoded German enigma codes . Alan Turing Way can be found in Manchester but you knew that PP and , I suspect, did most other ABers.

Retro 09:02, oh really? I hadn't read that. Thanks Retro.

[retrocop]

Will send a link.

Already there are allegations that the US knew of the implosion at the moment it happened but kept quiet in order to protect their top secret submarine detection system?

[naomi24]

This makes interesting reading. James Cameron, director of the movie 'Titanic' has made 33 descents to the wreck, says 'OceanGate were warned.

https://www.bbc.co.uk/news/world-us-canada-65994707

This too, Retro, from my link.

//On Thursday, an official from the US Navy told the BBC's partner CBS News that the navy had detected "an acoustic anomaly consistent with an implosion" shortly after the Titan lost contact with the surface.//

Hopefully that's right and spared those men the unthinkable horrors of the alternative.

[Khandro]

As I said yesterday on the other thread; the estimated time for descent was two hours, the automatic pinging stopped after one & three quarter hours. That I believe was when the structure imploded, they never even got as deep the wreck.

There are many questions to be answered, not the least of which is how this piece of junk was allowed to be put to use.

[Tilly2]

I'm relieved that it was a sudden ending for them and not a long, drawn out death.
