Missing Titanic tourist submersible

[al_infierno]

Wreckage belonging to the missing sub confirmed found 1600 feet from the Titanic shipwreck.   USCG is saying the sub sank due to an implosion.  All hands lost.  At least it would have be quick.  RIP.

RIP.

Well, the life of an adventurer was never said to be one without risk. 

In the words of the Kurgan "It's better to burn out than fade away".

RIP.

May they rest in peace. 

Sounds like the US Navy may have heard the implosion on Sunday.

Damn. RIP. Too horrific for my landlubber brain to contemplate.

I feel for the kid. He was legitimately terrified to get on the death sub and felt pressured from his father who was obsessed with the titanic. That's some bleak shit.

Yeah, that was the worst part.  Grim.

Saw that too, apparently the trip was a Father's Day promise.     Really sad.  The others at least seemed to live a full life beforehand.

James Cameron talked about the incident in an interview (being an experienced and respected member of the deep sea exploration community) and he said that apparently the sub had utilized its emergency floatation devices prior to implosion, which seems to evidence that they were aware of an emergency and attempt to avert it

if it aint Woods Hole or USN Im not getting in a sub that isnt tied to a pier.

[Dammit Carl!]

Poor kid; deserved better.

So, now comes the legislature for "adventure tourism," (as I'm calling it) if accidents in the past have shown us anything.  What shape(s) do we see the legislature coming as?

[GDS_Starfury]

personally I dont think that civilians should be allowed access to sites like these.

Leaving aside any related political dispute -- there's an interesting security dispute about the US government not revealing we heard the implosion and quickly figuring out what it was (no doubt due to sonalysis and positional triangulation), yet leaving people strung along for several days hoping that there might be a rescue, which included several organizations mobilizing at cost to hustle out there.

Would revealing what we already knew, really have been too much of a security breach about our capabilities? If so, why eventually reveal how and when we already knew? Seems like it should be pretty standard capability well-known by now, anyway.

Thanks, I like Brynn's military analyses.

Triangulation I accounted for, though not sound propagation and distortion (e.g. due to the saline layer, too long since I played sub games) -- though again multiple detections would get horizontal and vertical bearings for generating box boundaries. How many sub-implosion signatures could be expected within that box, aside from the Titan, and also not expected to be identified by other means fairly quickly? Multiple acquisition would also reduce (at least somewhat) mistaken identity from geologic noise.

I expected the waterfall to match at least computer profiles for implosion effects, and Brynn suggests that probably did happen. Although then again, the unusual materials for the Titan could have affected standard profile recognition. Then again, bubbles (as Brynn suggests) might be detected rising (and traveling somewhat laterally).

The hustle was of course correct, even if all evidence was 'consistent with'. I get that; looking back at my post, my wording was bad for what I was intending -- I'd still be in favor of multiple groups hustling out there, just in case!

I wouldn't have thought there would be any usefully new information gleaned from a platform (largely) declassified since 1991 (and studied as much as possible by our enemies, and allies, before then), by an announcement that the Navy has checked its sensor platform logs and found detection evidence 'consistent with' the sub's implosion in the marginal vicinity box of the sub's expected location (and not going into detail how that evidence was acquired).

If I was a family member, I would have wanted to know as much of the probabilities as possible as soon as possible, and generally why I should expect x to be probably true, so long as security wasn't compromised; and I still don't see why a general announcement without methodology details (not even mentioning SOSUS as a detection platform for example), would have compromised any security. Iran might not know yet that World War I-era passive sonar applications are possible, and used by the United States (perhaps also other nations), but who cares if they finally catch up to knowledge about mid-1910s naval tech this way?

But maybe the DoD was erring on the side of caution toward any families who would rather not know the likelihoods sooner. It's horrible for everyone. 


I've read somewhere that the teen boy knew how sketchy the company's tech and construction was on the sub, and was terrified about being put in there, but had made a promise to his dad on Father's Day to go (or something like that). I hope that was only a rumor...

Saw this in multiple reports as well.  Can't imagine how angry and devastated the mother must be.

Couldn't it also be the case that since the implosion happened hours *before* anyone from the Titan's mothership called the authorities for help, the recordings of the event were already filed away and only later retrieved after the Navy had diligently sifted through the ungodly amount of sonar data they had collected in the hours before and after the alert went out?
