Also shows a titanium ring like the ones supposed to be bonded to the end of the carbon fibre tube looking completely separated. That should also be bolted to an end cap.

Part of it being recovered, I wonder if thats the viewing window and if it was removed to make it easier to unload with the strops or if that was the failure point(iirc it was never rated for 4km pressure and they delined to have custom rated one made for it). 

 

 

I'm not an expert (or even close to it), but if the carbon fibre body (or the join between the carbon fibre and the titanium endcap) was the failure point, I suspect the massive sudden force of the implosion could blast the viewing window out.

 

I'd imagine the fact that the titanium endcap appears to have completely retained it shaped will tell them a lot.

There is a difference between populace and politicians.

 

 

I agree.  That is why I was careful to attribute the actions to Nations, not nationalities.  That said, and at risking of stating the obvious, culture is a factor in the behaviour of nations.  China for example has a historical penchant for occasional bloody upheaval.

A look into the future, when civilians/tourists get killed in a space launch.

What are the odds of a safe rocket launch?

A great article in the New Yorker about this. Sounds like lots of people in the know realised that this was a matter of when, not if.  A good example of how OceanGate ignored/worked around regulations was that to avoid liability and standard passenger safety requirements they designed and built in the US, but registered it in the Bahamas, and never officially had "passengers" or "fares", but rather everyone was a "mission specialist" who contributed money to a different one of OceanGate's entities.

 

As a good example of the lack of checks and redundancies they had in place, one one trip with paying passengers, it was only when it reached the bottom that they spotted that a thruster had been put on backwards, so instead of moving in a straight line the submersible would do 360s - they ended up taking a couple of hours to look up internet instructions and remap the controller.

What science of any value were they doing? They could have clipped a monitor screen on the front of the porthole and given the passengers a VR experience in 10m of water.

It's likely they weren't doing any genuine science - that was just a measure for the company to avoid having to comply with full tourism regulations.

It was an empirical evaluation of the question "How often can you take a shonkily constructed carbon fibre cylinder to 400 ATM before it fails"?

Experiment in Physics vs an inspirational leaders 'reality distortion field' ?

 

Lochridge, the original test pilot with commercial submersible experience met with hostility and fired, 
when he advised that testing of 'one of a kind' submarine structure was needed.

 

"Lochridge shone a light through a sample of carbon fiber and saw splits in the midsection..."

Interview with Karl Stanley who operates his own design sub in Honduras. 
Only other operator doing deep sea tours though not as deep as Titanic and uses classical metal construction.

 

Was on the second dive of Titan in April 2019
Reported the loud cracking noises, more like gunshot noises that then continued on ascent all the way up to 300ft.
It happened on the previous dive which was the first with Stockton alone to full depth.

 

Karl had to point out to Stockton that he should be concerned about this. 
Stockton initially wanted to continue, just tell people the sounds of gunshots are normal !

Titan was the name of ship in a book that came out before the Titanic disaster about a ship struck by an iceberg !
I give fate the finger!

Not sure if this has been posted before but the BBC did a two-part docco last year on what it's like to travel in the sub. It contains the by now well-known story of the thruster wired in reverse, but also another one that on one dive they lost power and Stockton suggested just waiting until the weights auto-released after 24 hours or so. So they allegedly had n failsafes of which n-1 didn't work and they were hoping the last-resort one would actually work (who knows if it was ever tested). Eventually they got the hydraulic release working (barely) and made it back up. From what people are saying on there it looks like they had problems on pretty much every mission, in a situation where any real problem means you die in the real world, no respawning at the last save point.

Great story in the New Yorker with interviews from a number of people (formerly) involved with Oceangate on how Stockton Rush managed to avoid any kind of controls or regulation of his work.

Thanks for that.

Every quote from Rush that comes to light just paints a worse picture. What a sh*t show.

Scary read, especially how they seem to have spun many of the problems to present them as positives. Like bragging about how safety conscious they were with their acoustic early warning system, which was actually only there because they knew there was a very real possibility of the hull failing!

"Exhibit A, your honour".


Innovation is the tech bro equivalent of the sovereign citizen words. It’s particularly useful for accessing venture capital.

 

In hindsight, remember that guy who tried to use legalese in an attempt to obtain a free battery that was long out of warranty? I wouldn't be surprised if he's a sov-cit today. given the "bush lawyer"-speak he was using at the time. To this day, I'm still waiting for him to sue us, not that it matters anymore because the company has since been bought out by a nationwide chain.





"I regret to say that we of the F.B.I. are powerless to act in cases of oral-genital intimacy, unless it has in some way obstructed interstate commerce." — J. Edgar Hoover

"Create a society that values material things above all else. Strip it of industry. Raise taxes for the poor and reduce them for the rich and for corporations. Prop up failed financial institutions with public money. Ask for more tax, while vastly reducing public services. Put adverts everywhere, regardless of people's ability to afford the things they advertise. Allow the cost of food and housing to eclipse people's ability to pay for them. Light blue touch paper." — Andrew Maxwell
