Behind the Bastards did a pretty great two-parter on Stockton Rush, and how a) he completely shit the bed while ignoring all the super-deep-exploration experts, and b) how nature was totally telegraphing to Rush and OceanGate that this submersible is totally not doing it and will end in a spectacular tragedy, only no one else will be down there to watch but the fishes.
The controller wasn't a particularly weak link, though for safety's sake I'd want there to be a redundant spare, and it set up for plug and play. But higher on my priority list would be things like integrity monitors and an emergency way to open the sub from the inside (the hatch was bolted from the outside, and there were no emergency exit measures.
To be fair, they all exited the vehicle pretty quickly at the time without it needing to be unbolted from the outside. Experts... pfft.
The sound made as they exited, spaghettified.
Extruded?
Nonsense, "spaghettified" is a perfectly cromulent word
Such bad taste, sir. Have a reluctant upvote for that absolutely crushing wit.
Are you hoping to get upvotes for “crushing”?
How dare you. I would never go so low
Fr srious tho, it is really tragic. The young man especially; he was completely innocent and deserved better
Emphatically agreed
... How do you propose to emergency exit that sub at 1000 meters depth?
I'd say the bigger issue is that he used a carbon fibre body, a material which has great tensile Strength but sucks for this.
They way bigger issue than that is that he glued the metal rear section to the carbon fiber body. Both materials expand and contract differently under pressure, which is not what you want at 3 kilometer deep pressures, especially with multiple descends and ascends. That glue could never keep those materials together, that alone was a disaster waiting to happen
And people usually consider this when building a barn, doing plumbing in a house. The scariest thing is how can someone who doesn't understand this make a submarine. Real Crassus vibes.
The problem was that if they surfaced away from the support vessel, there was no way to open it to get fresh air. So you could still run out of oxygen and die while floating around on the surface waiting to be found.
Yeah that sounds like less of an issue to me, honestly. That support vessel van be there quick enough, send in airplanes, whatever. You can make a more intricate inside and outside locking mechanism but that'll make your entire submarine a whole lot more expensive
Why are people still discussing this as if something wrong had happened?
They fucked around and found out.
These people thought they can make a life size toy sub and use that instead of a normal one, and that people with actual expertise are below them.
Anyone who uses the F710 more than an hour will have it randomly disconnect like twice. No idea who okayed that part but it wasn't even the affordable option at the time as it was ALREADY years out of production when they built the sub.
I have that exact controller. It sometimes randomly disconnects forma few seconds. It is a weak link.
