Titanic tourist sub missing

[erwinl]

Possibly the results of an implosion varies a lot as a function of the depth?
I don't know.

We do know the descend was still ongoing.

Edit: And human remains in no way means that bodies are found. This could be as little as a finger digit that was found.

 

[TurkeysGhost]

Interesting that human remains have been found.

Someone suggested that the bodies would have been turned into "strawberry jam" by the force of the implosion. I wonder what condition these remains were in? Some of the mechanical parts I see seem to be fairly intact.

Well, I'm guessing the intact parts are the ones more likely to be found. Pieces that got thrown clear of the implosion are probably going to be easier to find than little bits of debris.

I'm curious how much of this debris is from the inner portions of the cabin, where I assume the force of the implosion was most violent, vs exterior portions that might have been blown clear.

My guess is that it probably had a lot to do with it. Rush was very intelligent, charismatic, and like any good salesman, he truly believed in his own product.

I don’t think this has been posted yet — journalist David Pogue was invited to go on the Titanic expedition last year. At the 2:40 mark, he answers the question “Why would anyone get in that thing?”

In addition to what he says here, all the negative things— the people and organizations who warned him that he was taking too many risks— were not known to the public at that time. If someone was searching for info on Rush and OceanGate Expeditions, they’d have been more likely to find the neutral-to-positive article in the Smithsonian, or OceanGate’s own well-made marketing videos. Imo it all gave a pretty convincing illusion of being risky (in the sense that mountain climbing or bungee jumping are risky) but ultimately “safe” in the sense that with proper equipment and following proper precautions & protocols, you’re not likely to come to harm.

Somehow I don't think there's any way to make a connection between "doing any testing on our products is for losers" and intelligence.

I bet there's a correlation between "doing any testing on our products is our losers" and self-perceived intelligence though. Nothing in this world more dangerous than a moderately intelligent engineer who thinks they know best.

As I understand the MATERIAL was rated for 1300m, not the window itself. Presumably they could cut it thick enough to withstand whatever pressure... at least a few times. Just like it was with the carbon fibre in the hull.

I thought it was interesting in that long interview he did he claimed he would have enough warning of any problems, with the window it would be crazing, with the hull, squeaks and pinging sounds. It wasn't enough, obviously. They say he had dropped the weights and was on the way up when the implosion happened, so he seems to have had just a little warning.

horrifying way to go if true. Maybe our "move fast and break things" submarine captain had a moment of clarity before the big squish.

Ummmm I can't actually RECOMMEND anyone doing this because it is extremely Not Safe for Life but I've seen the pictures of the bodies after the Byford Dolphin accident (I will NOT link to them here but they are on the internet if you want to go find them but serious and final, no joke warning, extreme gore) and... it's weird what survives and what doesn't.

Pressure and the human body are both weird in how they reaction to things.

ETA: For clarification/expanding info the Byford Dolphin was an oil rig who in 1983 suffered a horrible decompression accident that killed 5 members of the saturation diving crew when a valve between airlocks was opened improperly between one side of the airlock at 1 atmosphere) and another (at between 8 and 9 atmospheres) which caused, to put it bluntly, the 4 men inside the airlock to pretty much instantly be sucked through a 24 inch opening with incredible force, force enough to flash cook the fat cells in their blood, with the men basically being completely liquified but sections of their bodies, including a complete and intact liver which "looked as perfect as if it had been surgically removed" where also found. (The 5th man was a safety observer killed by explosive decompression)

Hard to imagine a better example of the 'Dunning-Kruger Effect' than this craft. There have been many successful designs built over the years capable of taking crews to such depths (and deeper). Unfathomably, the people responsible for this one ignored such proven know-how and presumed they knew how to do it better.

The "massive interest" in this accident is interesting though.

 

[IsThisTheLife]

Several accredited experts in submersible design have noted that the use of CF-composite was bordering on perverse. It's a material used where strength-to-weight is the imperative which in a marine context is relevant only in racing craft (yachts and power-boats).

 

[JoeMorgue]

It's comic book thinking. "Is adamantium stronger than vibranium?"

"Strong" is not a single factor in materials. Are we talking tensile strength, compression strength, weight bearing, do we want the material to flex, are talking sustained force or peak force, etc, etc, etc.

Carbon Fiber is a goddamn miracle material when used properly in things like aircraft and surface vessels and race cars. It's a horrible choice for pressure vessels.

In other words the US Navy has never tried to built a submarine out of carbon fiber and the US Navy once tried to build an aircraft carrier out of ice. (Well the British Navy, the US was involved.)

Oops!

I'm currently less curious about the submersible's mode of failure than about how the debris was located and then how the pieces were retrieved.

Rovers/drones. Unmanned equipment that can operate at that depth is WAY more common than manned equipment that can.

Remains to be seen.

My kind of humour.
Nommed.

It appears to be the Odysseus, a DSRV operated by Pelagic research.

The son apparently did want to go on the descent.

The mother of the teenager who died on the Titan submersible has said she gave up her place to her son “because he really wanted to go”.

Suleman Dawood, 19, and his father Shahzada, 48, were among five people who died when the vessel imploded on a journey to view the wreck of the Titanic.

Christine Dawood told the BBC the original trip had been scheduled before the pandemic and said her son had been disappointed that he was not old enough to accompany them.

She said: “It was supposed to be Shahzada and I going down. I stepped back and gave the place to Suleman because he really wanted to go.”

Asked how she felt about the decision, she replied: “Let’s just skip that.”

She said “both of them were so excited” and her son had taken a Rubik’s Cube with him because he wanted to break a world record.

 

[JoeMorgue]

The 19 year old is the one part of all this that feels unapologetically actually tragic and I do feel genuinely sorry for him with no reservations.

Oh no doubt that the CEO thought he was the smartest.

Correction to my post 723:

I incorrectly said the adhesive color that was used to glue the carbon fiber hull to the Titanium interface caps was green. According to an OceanGate video, "Bonding the Titanium Ring and the Carbon Fiber Hull," the correct color of the adhesive is gray.

Let's hope it wasn't just PL construction adhesive.
