I wondered why they can't install a GPS anyway on the sub so that when it eventually does get to the surface, at least they can be found then.

Bit of a tangent maybe, but according to some expert I heard on the radio this morning, it's a submersible and not a submarine precisely because the vehicle is so totally dependant on the support ship. That includes everything from communication to getting in and out.
It's dependant on a support ship but it's not tethered to it? Maybe depth prohibits that?
According to the NYTimes, OceanGate refused to undergo any sort of external audit/certification process [0]. I would imagine using an off the shelf, cheap controller would have been one of the first things to be flagged. Makes you wonder how many other critical components did they skimp on [0] https://www.nytimes.com/live/2023/06/20/us/titanic-missing-s...
This is what actually amazes me. The reliability of something like an airplane, bus, or train, is held to extremely high engineering standards. There are even safety rules for bicycles. But you're allowed to take people for rides in a submarines with barely any oversight.
It's complicated somewhat if the submarine is launched and operated in international waters, however.

At those pressures I don't think you would want to open the door even if you could. I was more thinking about being at the surface and having nobody else to unbolt it from the outside.
Oh yes, I am (though I am absolutely not a real engineer nor do I have any experience with subs) just questioning why they would need to bolt it from the outside anyways. If it was to keep occupants in, I would imagine that a door that opens outwards would solve that issue if submerged, and would still be openable on the surface
From what I read it is also the first carbon fiber deep water vessel. I find that scary as carbon fiber does not start to bend before falure, it fails catastrophically.

Yes, if one had the budget to do all those things, from scratch, better than an existing component manufacturer. Not many companies have NASA levels of "throw money at it until it works, and every part has been signed off on five times." Absent that, I'm having trouble seeing how custom > COTS. In all probability, anything in-house would have been worse and added new failure modes. Better to buy, analyze, and adapt a…
If you can't afford to qualify the components on your 4000m diving vehicle, you can't afford to make a 4000m diving vehicle. See: the fact that they lost their diving vehicle.
I'm not sure why everyone is taking potshots at a company for trying something crazy with willing passengers.
Everyone involved knew what they were getting into.
Kudos to them for trying, even if they're dead.
> See: the fact that they lost their diving vehicle.
That's an awful lot of keyboard engineering, given nobody knows what happened yet.

The alternative is death of 134 odd people. Not ideal. :/ I would expect some e2e encryption satellite communication, however that might be still traceable to the enemy listening posts. Man, I now need to watch "Hunt for Red October" again [0]. lol [0] https://www.youtube.com/watch?v=3C2tE7vjdHk
Its practically impossible to do satellite to undersea communications. Being underwater does all kinds of hell to RF signals. Even just reliably doing undersea to surface communications is pretty tricky. Is your phone waterproof? Stick it a sink full of water. Watch it lose all network connectivity.
That should work if it's floating I would think?

How is Logitech “off brand”. They are well known for input devices.
Their controllers are well known for being garbage. People that take video games seriously can tell you all of the different reasons why they "feel worse" or are just less reliable than OEM. It's a $30 controller where the "standard" option is around $60. The "premium" market where they are custom made for important use cases (ie, competitive Melee tournament) can easily reach into multiple hundreds of dollars, using…
Although, for some reason, it's currently sold-out everywhere.
