What the fuck did Logitech do wrong here? If anything, that controller was the most functional part of the sub

Put it in a bag of rice and it probably still works! Assuming it's still whole.

It's not. When the sub collapsed, it did so with the energy of about 50kg of TNT.

This is why there will be no attempt to recover the bodies either. There just isn't anything left.

Fascinating. Where did you get those numbers, I'd like to read more.

I got them from this Scott Manley video: https://www.youtube.com/watch?v=qdz9vcSFBqw

He explains that the energy contained in a vessel is equal to the difference in pressure on the vessel wall, times the volume of the container.

WhiskyTangoFoxtrot,

There's a row of them along the top of the keyboard, and another block of them on the right-hand side.

RheingoldRiver,

help, I tried pressing the ones on the right, but my cursor just started moving all over the place. Did you hack my keyboard?

WhiskyTangoFoxtrot,

Yes. Send me bitcoin.

RheingoldRiver,

Ok, I've sent [up][left][left][left][down][down][down][down][right] bitcoin to the address [up][up][down][down][left][right][left][right]...[enter]. I hope you're happy now.

WhiskyTangoFoxtrot,

I think I've got 30 lives.

W = p Δ V
The Sub had a Volume of the 142 cm (56 in) internal diameter, 2.4-meter-long (7.9 ft) carbon fiber-wound cylinder
so 3.8m³ of air, should be about 3.8m³ x 4x10⁷ Pa = 152x10⁶ J, 152MJ

TNT has about 4.2x10⁶J/kg, so I get about 36kg of TNT.
But I ignored the front and back Domes, which will add a bit, and possibly have other issues as well, so the ballpark should be right.

Ironbeagle,

Maybe it developed stick drift and kept bashing them into the Titanic.

I had that happen once. Only it was a Logitech flight stick and I was playing Elite Dangerous. Things can get pretty scary in space when you always yaw left.

thefloatingpoint,

That’s internet mobs for you. They will leave as soon as it gets boring.

This shows how fragile the stock market really is. What nonsense.

This should have happened after they started using sub-par switches on their mice.

I see what you did there...

It's hardly their fault, I'm sure if anyone had asked them about counting on their stuff to keep 5 people alive they would have reacted with horror like anyone else.

Auli,

Sure but the operation of the sub had nothing to do with the implosion.

Bipta,

That seems like a safe assumption but we can't be certain.

The biggest issues happened in the "BSASW" connection. Nothing Logitech could do about what goes on between seat and steering wheel.

RosalynKirk,

I see nothing wrong with using a Logitech controller for this purpose. They kept spares so even if they died somehow, you could just swap in another. And even if the batteries died, and you were a complete asshat and didn't bring any extras, you could likely just plug it in.

It's just hilarious that people are constantly talking about this controller and not the myriad of other legitimate safety red flags.

WhiskyTangoFoxtrot,

The F710 doesn't have a USB connection. It won't work without batteries. The F310 would have made more sense, since it's wired and I doubt that rumble is needed for piloting a submarine. It'd be cheaper, too.

AFAIK they used a wireless controller so they wouldn't need to make holes in the pressure vessel, and the receiver was mounted on the outside with the rest of the control electronics.

To me, using a Logitech controller is a red flag. Not that they used a controller, but that they used a cheap knockoff controller, not an official one. (I had a Logitech controller when I first got a gaming PC; I could not get a different one fast enough). It’s a red flag because if you cheaped out on the controller, what ELSE have you cheaped out on?

That was one of my first thoughts when I saw they used one, and it turned out they cheaped out on a lot.

RosalynKirk,

Spending less money doesn't necessarily mean you "cheaped out". Spending more money does not guarantee reliability.

You may not have liked it and it may not have been great but it likely got the job done perfectly fine.

mrpants,

They cost slightly less than the Xbox/PS ones and used to cost more. I used to own one and they’re not the most comfortable but are built like tanks. My guess is the reason for choosing them was something other than cost.

The now-deceased CEO of OceanGate was proud of having bought carbon fiber to use that was half price because it was past the shelf-life for airplanes. So I’m sticking with he was doing things on the cheap.

Katana314,

The idea of stick drift seemed like a reasonable concern to me. If the controller simply stops operating, that's only a little bit of an annoyance in favor of using a spare. But, if the controller starts forcibly inputting X: 0.5 at a standstill, that could do something really bad like have the sub constantly trying to turn right. If the system pairs with no easy on/off switch, they could have difficulty working out a way to disconnect it to get a working one in place.
