Tube🌿Timeoh wow, the Titan Sub accident investigation has a bunch of new documents on the US Coast Guard site: https://www.news.uscg.mil/News-by-Region/Headquarters/Titan-Submersible/
looks like the prototype hull failed. i can't really see the crack the report discusses but it looks like some sort of spalling or layer separation.
omg they reused the titanium domes and rings from the prototype!? also they covered the outside of the hull so there was no way to visually inspect it.
final hull testing was done to a safety factor of uhhhhhhhhhhh 1.09. that's more of a danger factor.
ahh yes unplanned environmental testing. this thing was stored, uncovered, outdoors, near the ocean, for 6 months! unbelievable.
more unplanned shock testing. the thing was pointing straight up with everyone in the sub up against the back wall, then it kept slamming into the launch platform for an hour. that must have been miserable.
omg the CO2 scrubber system is just a plastic container (for the chemical pellets) with a PC fan hot glued on top
the onboard computers appear to be off the shelf Neousys Nuvo automotive embedded computers. wow, i've worked with these before.
i'm getting some strong "my first gamer PC rig, what do you think guyz" vibes here
got some cable pr0n for you all. 🤮 who in their right mind would trust their life to this crap. smh.
everyone remembers the game controller. the stick extensions appear to be 3D printed.
found more pics. the O rings weren't properly designed, the one on the left sits too deep because the groove wasn't machined correctly. There's also a plunge hole (presumably to get the undercutting tool in) that is a serious weak point.
the end sections of the hull, after being machined down to length, left these pieces behind, which show evidence of delamination. on the right, they put a bright light behind it and you can see it all the way through. very bad!
the flooring material (they used HDPE, high density polyethylene) was definitely not flameproof. what if some of that messy wiring shorted out and set fire to the floor? just everything about this vehicle was shoddy.
your auntifa liza 🇵🇷 🦛 🦦@tubetime am thisclose to a panic attack (no, am not joking) reading this. this was a death sentence from the very beginning.
when Walter Benjamin said that capitalism is a death cult, this is exactly what he meant.
locastan@tubetime "Fake it 'til you make it"-mentality when it comes to extreme conditions.

@tubetime summary of the report: this is what happens when you let billionaires/techbros design and/or build stuff that should keep lives secure and safe.
Jeff Haluska@tubetime Sheesh, this feels more like a movie prop than something intended to go to extreme ocean depths.
We've all done hacky things but not in such unforgivable environments with risk of life for....tourism.
Bornach@tubetime They were probably thinking when has a failed O-ring ever been the weak point that led to the catastrophic failure of a hugely expensive vehicle while carrying a civilian to an extreme environment where only a tiny few humans can afford to visit?

nota@tubetime this is actually the most wild bit to me so far. Like the other stuff is mostly just being scrappy to an inappropriate degree and doing the same sort of stuff we'd do in robotics club but with lives on the line.
But the fact that someone had to sit there and manually type in all of the numbers... that's not even scrappy that's just absolutely bizrarre.
I always thought there was something funny how they had zero info on what happened to the ship... makes sense now.
