Let’s also not forget that there was no way to exit the submersible from the inside. The door was bolted on by the surface team. So if they had just lost power (instead of being crushed), they would’ve been floating on the surface with no way out. That’s the another obvious horrendous design choice.

Was the issues not multiple, like the carbon fibre hul not made using vacuum technologies but just like roll on the sheet and some epoxy in a warehouse, that carbon fibre being strong tensile wise but not compression wise, the titanium carbon fibre interface and their different stress deformations due to pressure, having the Titanic OST playing the whole time, like multiple safety shortcuts and maybe using a game controller as your only form of any interaction, like what happens if some kid bites the cable or something

I have worked in underground mines, and this scenario of being bolted inside gives me way more cluster phobia than any experience I have had

I work on submarines. Everything that company was doing gave me a panic attack. The SUBSAFE program exists for a reason. Like, there’s a time and place for innovation, and when people’s lives are on the line is NOT it.
notaviking@lemmy.world 6 months ago
Usually these program’s rules seem very tedious and restrictive and I can easily see one person looking at this and think they are in place to stifle innovation and keep the little guy out.
I remember how he said to not have regulatory approval because of of this or that, but why not get a regulatory expert to have a look, might not approve your vessel but might show clearly missed safety critical blindspots.
But these rules exist for a reason, they where usually written in blood, it’s how I know this incident added rules to your SUBSAFE program.

For some reason I thought it was rolls of prepreg. I don’t know that I’ve ever seen raw tows used with separate resin.
notaviking@lemmy.world 6 months ago
Ok it probably was prepreg now that I think back, but I saw the application video where the just rolled it on no vaccume bags to remove any voids or cavities

That’s insane. No NDI then as well. Just fucking suicidal.

It bugs me that everyone harps on the controller. It’s far and away the least suspect part of this.
Multiple generations of hardware iterations by many competing companies, well defined and understood software interface options, literally billions of hours of testing, easily replaceable, several axes of control, and a huge portion of the population has at least some experience with one.
There’s a reason the military uses them when they can.

I mean, using a controller in and off itself is not suspect, but the model they used is the cheapest one you can get with a recognizable name and is known for being unreliable, which is absolutely a suspect decision to make when it’s the only method of control
notaviking@lemmy.world 6 months ago
I have no issues with the controller either think it was a great addition, were I had one is that it was the only way to operate the vessel, so not an addition but the sum total of controls.
Like if you were bolted into a vehicle, with now way to interact with the outside except a tiny window and only a game controller, it is a lovely piece of efficient engineering and does everything you need, but if this controller maybe gets damaged for example it’s cable was unfortunately pinched off by someone’s shoe. When you realise at a 1000m the closest thing to a god is that controller working and taking you safely back to surface in time or being stuck and hoping the guy who got you into the mess, that his, only other plan the dissolvable ropes on the weights actually work and you get to surface and get found and unsealed before air runs out.

Fair enough.
Top to bottom the design of the thing is just a testament to arrogance and “engineer’s disease”.
notaviking@lemmy.world 6 months ago
I think this was the original sin, the root cause. One man’s vanity and arrogance, which made him blind to his own shortcomings. He build something great, let us not lie, but we can clearly see in hindsight the obvious truth. Well if what people that know way more than I do are right, the vessel imploded quicker than the neurons in your brain, so it must’ve been an quick painless death
