Tourist mini sub missing off titanic

Just my thoughts too

So all the banging sounds, purportedly by the 5 occupants, picked up by the aircraft and all over the news were what? When did the implosion take place?

Sad but somewhat predictable ending, just glad it was more than likely over very quickly.

I heard in the news that the implosion happened at the time of the loss of comms, a Navy vessel heard it.

I just heard on the news that they picked up a sound that could have been the implosion when they lost contact days ago but were not telling us.

James Cameron's sub.

Actually, not. Slowly suffocating to death would have been far, far worse.

Note I wrote "outcome" in my post but I get we're your coming from.

Navy just said it detected an “acoustic anomaly” shortly after the Titan lost contact, so Sunday…

[JavaBrewer]

If any of the reports about Navy detection of implosion are based in fact I can see a continuation of this conversation in PARF. Please don’t take this thread there, start a new one.

How will this influence the second to last and scheduled next visitors? Can only hope that it is a wake-up call akin to any other near-death experience and wonder if they would be willing to eventually talk about it.

Probably not going.

Why would possible Navy detection of implosion on Sunday be PARFy? I would think/hope we have undersea listening stations all over the place, and I’d imagine we don’t disclose much about them or their capabilities. If the Navy quietly informed the CG on Sunday and the searchers used that info to identify a possible location (as is being reported), that’s fine. If the Navy didn’t disclose anything to anyone, that’s fine too - to me. These are secret national security assets after all, and not to be compromised, whether that helps or hurts a search for a lost vessel is immaterial - again, my opinion only.

Funny story: I knew a guy who kayaked from California to Hawaii, solo. Took him two months, he ran into storms and huge seas when he had to paddle all night to stay upright, dead calms with no wind for his little sail, and dead zones where there were no fish, he ran out of food, was eating his toothpaste, thought he was going to die. He was out of communication the whole time, this was in the 80s, all he had was a sextant. His family asked the Navy to search for him, Reagan said no. Ed told me, on one of our Baja kayak trips ten years later, that he ran into a Navy ship out there and asked them to tell his family he was alive. The ship said, in effect, “we were never here and we didn’t see you, goodbye”. That’s not in the few articles about his trip. I don’t know if it’s in the book he recently wrote about the trip, which I have but haven’t read yet. I am not sure if he might have hallucinated it.

Another thing he told me was that one day he was sighting his sextant and something was blocking his sightline, he was frustrated and didn’t understand, then it finally dawned on him that it was one of the Hawaiian island peaks.

Most impressive guy I’ve ever known. Before the Hawaii crossing, he spent two years kayaking around South America. A drug gang captured him, demanded his money and drugs, said they would kill him, he got mad and said he didn’t have any money or drugs and was going to leave on his boat and they could kill him if they wanted to. They laughed and said he was crazy, and left.

One trip I did with him, we were out of sight of land and paddling into the wind for eight hours, at the bottom of the swells all you could see was water, at the top all you could see was sky, people were puking and getting towed by other kayaks, he dead reckoned us to some tiny island off Baja and while we were all laying in the sand exhausted he slipped off with his speargun and came back with rockfish that we ate raw from a Frisbee. On the return trip it was glassy smooth, only took four hours, he saw spouts and steered us in front of migrating blue whales, we watched a blue whale surface in front of us then submerge and glide barely under our boats.

Sorry for the digression. Was thinking I’d rather be terrified in a kayak somewhere off Baja than get into something like that submersible. We were a hell of a lot safer out there, and I got to see a blue whale up close.

Thats why the guys designing the Trieste used tanks full of gasoline. The gasoline was incompressible so it could withstand sea pressure and it gave the craft a degree of positive buoyancy to offset the pressure hulls negative buoyancy.

The Trieste was sort of an underwater Hindenburg, minus the fireball. The Hindenburg's structure was heavier than air and the bags full of hydrogen gas was lighter than air.

I have not done all of the reading, but I suspect that any/all or nearly all submersibles that visit the Titanic wreckage are constructed differently, and none feature a composite material.

I doubt any of them can carry more than 1-3 people.

But again, I have not done the reading.

I think read a news story that suggested that there are less than a dozen submersibles in the world that can go that deep. Not a dozen designs, but rather a dozen actual vessels.

If implosion is either confirmed or one of only 2-3 theories supported by research on this tragic accident, it just might be concluded that some element(s) of design, construction and/or maintenance were involved.

Airplanes did not start out as 747s, and now they make airliners with composite fuselages.

It took a while to get to these "achievements" in aviation I reckon.

In any case, thoughts to friends and family members of those that were lost, and thanks to those that tried to help them.

[LEAKYSEALS951]

I watched a video of a friend of one of the people on the sub.

He stated something like "This sucks, but damned if we are going to sit on our couches because of it."

I'd argue this resonates with us all to a degree on some level (perhaps not THIS level), but, I get his point.

[cjh]

Didn't they announce finding a debris field today made of pieces that were consistent with the subs construction?

I read about the Trieste today. Twice as big a vessel with room for only 2 people. And went much deeper. Interesting stuff. I’m surprised those lost this week were so accomplished yet got into this very questionable vessel.
