Krill?
Titanic tourist submarine missing 6-19-2023 (Debris field found, passengers presumed dead. 06-22-23)
As above, they did tell somebody but didn’t give it out to the public. At the time, sure, you follow up on it, but a random pop in the water is not definitive by itself. It’s like hearing a loud bang in your neighborhood. Sure, it might be somebody firing a gun (like “that” neighbor everybody knows about) but you shouldn’t jump immediately to that conclusion to the exclusion of everything else.
Welp, not absolutely confirmed but it looks like this is what happened.
Also;
The implication seems to be that this is a military listening system intended to look for Russian subs, which may be one more reason this information was kept from the public.
All you naysayers just wait: if and when the debris is covered, they’ll plug that sucker in (the controller) and it’ll still work. In fact it’ll prove to be the only component that didn’t fail catastrophically.
Yeah, a rigid helmet and flexible suit does not lead to good outcomes when something goes wrong. Lots of pressure on the lower extremities and little pressure within the helmet means everything below the helmet is forced up into it. There’s a reason that style without safeguards fell out of favor long ago.
It’s not the same as the free-diver example with a lungful of air. In that case, the internal organs wouldn’t come out too well, particularly the intestine (which is getting one hell of an enema). But the skin would be mostly intact.
Well… not exactly.
Back when I worked for Blue Cross my health insurance and company offered life insurance, remarkably, would have covered me in the event of an accident in the aircraft I flew, which were a mix of ultraight, experimental homebuilt, and general aviation. (I know this because I requested copies of the full policies and read the fine print.) Largely because it likely did not occur to the Powers That Be that they had anyone indulging in such activities. Also covered the skydivers.
But “Experimental” aircraft cover a range of things. Most of the ones I flew in were kitbuilt (only one was an entirely original design) and for the N-numbered ones the FAA did mandate some standards and flight testing before passengers could be taken aloft in them.
This submersible apparently had had no testing/certification and was not built to any official standard.
For those whose employer is a bit more narrow-minded in regards to coverage, there are companies that offer insurance policies to pilots, from medical accident coverage to life to liability.
Remember, aviation has been around a long time, it’s not entirely new. That actuaries can calculate odds on these things. For a Moon launch in the 1960’s? Not so much. No data to crunch back then.
In a sense, someone with a net worth of billions doesn’t need a life insurance policy, not like a working stiff with a spouse and kids in a wage-slave job might need one. The billionaire might still have one, but it’s not needed in the same way.
The countdown until they ran out of air was good for ratings. /s
Except that was the exact opposite (okay, not exact, given the orders of magnitude difference in pressure change): an explosive decompression, not an explosive (implosive?) compression. Which isn’t to say the outcome wasn’t likely gruesome in any event, just that I don’t know how similar the inverse of a decompression would be.
Dont check twitter. Some nut, it may be catturd, is saying it was prolonged in the news to overshadow the Hunter stuff.
…this is a Twitter thread from an admitted non-expert, so YMMV, but this is a compelling comparison between what happened here with the Titan and the construction standards of the Deepsea Challenger.

Why would a Billionaire waste his time with Life Insurance?
I’m not sure how the Twitter poster knows so many details about the Titan but its a very interesting read.
…most everything on that thread seems to (IMHO) match up with the publicly released information, or the various videos where the CEO is talking about the sub. It seems largely accurate to me, but again, fair to take it with a grain of salt.
There are a handful of inaccuracies. The Titan also had multiple backups for ballast, including timed-release weights. And the Deepsea Challenger hatch was also bolted on from the outside.
The Deepsea Challenger was undoubtedly built to a vastly higher standard than the Titan, in part because it had to be–going to the bottom of the Mariana Trench is far more difficult than visiting the Titanic. But people seem far too focused on mundane and unimportant details like the joystick. Most likely, the problem was entirely structural.
You’d think they would have learned from Apollo 1.
Years ago I read a book called Shadow Divers. Its the true story about the exploration of a U-boat that sank 60 miles off of New Jersey. I seem to remember a passage that described, in some detail, what happens when a sub implodes. Its all over in a fraction of a second. The book was an excellent read, BTW and if you have any interest in that sort of thing, I highly recommend it.
I was reminded of a weird little critter , the Snapping Shrimp or Pistol Shrimp. It’s claw basically creates a jet of fast moving water that crates a cavitation bubble, and when that tiny bubble collapses it creates an acoustic shock wave that stuns its prey , and creates a tiny spark of light indicating very high temperatures when the bubble collapses.
Given the debris is quite close to the titanic I’d imagine the accident happened at depth. Based on some studies of dropping very heavy things off of drilling rigs at sea , even big pipes weighing several thousands of pounds will rapidly go into a ‘falling leaf’ motion and then currents can take them away. For dropping a boxes shaped object less than 2 tonnes you would assume a scatter angle of about 10 degrees ( according to DNV) so for every 1000 feet you could get a scatter of 350 feet. without considering currents which will push things further . Flat lighter stuff will likely drift further .
There is a whole lot of work and modeling put into understanding how things sink and someone did a whole study on the debris fields of titanic and using it to meddle backwards it’s journey down. Google DROBs DNV for more. Anyway I am sure there will be some actual modeling done when the full extent of the debris field and the shape of the different parts are known and they will be able to figure out at what depth it imploded and I’ll likely be wrong , assuming the navy don’t already know based on their sonar detection of the event.
I suspect it’s a teeny bit easier to engineer an easily openable hatch that operates between 0 and 1 atmospheres vs. one that works at ~1000.
Yeah. Imagine the trash compactor scene in Star Wars. But the ram comes down at thousands of MPH and stops when there’s a couple thousandth’s of an inch of space between the ram and the floor. Everything that used to be inside is now a uniform slurry in that remaining tiny space.
