Since the story came out people fixated on "lol he used a shitty gaming controller" but really that is one of the least sketchy design choices in the entire rig. Why reinvent the wheel and make a custom set of controls that are realistically another huge expense and potential failure point, when off the shelf solutions exist for that component?
The corners that were cut are the ones involving the viewport/nose adhesion to the ships frame, and the structural integrity of the carbon fiber hull itself. They had test data suggesting it was a bad idea to engage in repeated dives with their design, and an even worse idea to operate at the depths they chose. They decided to ignore that.
From what I can tell the lawsuit (which is against Ocean Gate, not Logitech) is really just calling out the controller as another example of willfully negligent behaviour.
You're certainly correct that the actual cause of the failure was the carbon fibre hull. Just a terrible idea on so many levels. Carbon fibre, by its nature, is good under tension, not compression. It was never going to function well as a pressure vessel underwater.
There were a litany of terrible decisions made by Ocean Gate, such as not tethering the sub, because it was cheaper to launch it from a towed raft, but none of those bad decisions ultimately mattered once that pressure vessel failed. Those people were dead so fast that, to quote Scott Manley, "You go from being biology to being physics."
You can always bring a second controller for redundancy. I would bet money the game controller had zero impact on the failure and I hate all the shade being thrown on this innocent controller.
Having tried to use those, my main issue was the 710 is an unreliable 2.4ghz wireless, when bluetooth controllers all worked much better for me. I couldn't get the 710 to have reliable button presses from more than like 4 feet from my pc, so I ended up just using the 310 wired. Maybe there isn't enough interference on the sub for that to be an issue.
Wasnt the carbon fiber body rated for like, 1/3rd the depth that they dove to?
It was very NASA O-Ring vibes. "We did it once, so we can do it every time" at least until they cant anymore, and that cant is usually accompanied by regret and poor innocent people being salsafied.
Using commercial off the shelf technology without proper testing and certification is absolutely cutting corners. See: Kaprun disaster.
What kind of fire rating did those COTS parts throughout the interior of the vessel have? What kind of redundancy existed? Would you use a Logitech controller for a spacecraft? The requirements of deep sea submersibles and spacecraft are quite similar. Would any of the submersible certification agencies approved this? I think not.
I see the Logitech controller, the carbon fiber hull, and so many other decisions he made as symptoms of the same corner cutting, “move fast and break things” mentality he had.

I just read the wikipedia article; thanks for mentioning it.
I'm not sure it's a good example of your point, though. Notably:
the cause was the failure, overheating and ignition of a fan heater in the conductor's compartments which was not designed for use in a moving vehicle.
The onboard electric power, hydraulic braking systems, and fan heaters intended for domestic use increased the likelihood of fire.
The fan heater is the only off-the-shelf technology listed here, and there's no suggestion that it was part of the train's design. It seems likely that a train conductor brought it on board to keep the compartment warm through the workday. Still a bad idea in a train, especially on a 30° slope, but not an example of the designers cutting corners.
Edit:
Thanks to others for linking photos and a report (in German) that show how the heater was installed. It was clearly not a case of a conductor just setting the heater on the floor, but the installation still looks very much out of place. Perhaps corner-cutting was involved, but this doesn't look like something done by the train designers. Even an expensive industrial heater seems like it would be an extraordinarily bad idea in that location, right up against high-pressure hydraulic oil lines. Does someone have the details behind it? It looks more likely a (very foolish) modification made by someone else, like maybe the train operators.
For anyone else following this, those hydraulic oil lines that the heater was nearly touching were apparently pressurized at 190 bar, which I think is about 2700 pounds per square inch.
Exactly this. When you procure custom hardware, you’re paying (a lot) for the vendor to ensure that each unit meets the specifications you provide. If you validate off the shelf hardware like this, there is no guarantee that another batch of the same sku will also meet your requirements. Imagine training on these controllers then a certain batch of them has wildly different sensitivity.
This particular model of controller is notoriously terrible, unreliable, and prone to contact failure. Anyone reading the amazon reviews would know it wasn't even a good choice as a player2 little brother controller.
Dude, the F710 is legitimately a terrible controller with a tiny range and a manufacture flawed nano receiver. I mean it's not the steepest corner they cut but you can get a rock solid drone remote with ridiculous range for barely twice the price of an f710.
It was a stupid choice that they actively ignored the results. Like i said, ANYONE who uses this controller for more than an hour will directly experience how terrible it is.
The game controller is not managing life critical functions, that's called a computer. The game controller plugs into the computer. The great thing about that is that you can bring a second (or even a third) game controller for redundancy.
It's just that the engineering choices that caused the failure are difficult to understand or communicate in sentence so the game controller is something any idiot can harp on about and sound smart.
"Rush, who saw himself as an innovator like "Steve Jobs or Elon Musk," the complaint says, once told Pogue, "At some point, safety just is pure waste." Rush thought he had found a lighter way to build subs."
This really summarizes the mindset of most second+ generation rich people. Because this guy lived with a lot of inherited money and power all his life, he assumed that everything that comes out of his brain must be the ultimate truth. So much so that without even a single reservation he happily took his son with him to that journey knowing full well that the submarine was probably violating several critical safety requirements that he deemed unnecessary. We are basically being ruled by such people folks.
you should really consider frequency among non billionaires and among second+ generation billionaires. not that I have data on it but I really do think growing up in such an environment does inflate your sense of self idea worth and therefore such a person is more likely to act in this way (but not claiming at all that they are the only ones)
It appears they are suing OceanGate, the company that made the submarine. The use of cheap, consumer grade hardware for critical functions (literally controlling the sub) is one of their criticisms.
This controller kept me in rocket league gold for months. I put it on eBay and some shmuck said they need it in a submarine but are on a budget so max can do is three fiddy. I just wanted to get rid of the thing
The complaint does not allege that the Logitech wireless controller, the carbon fiber construction, Titan's innovative porthole, or the use of disparate materials with differing expansion/compression coefficients—four main areas of criticism—were individually responsible for the sub's implosion. But it does suggest that these systems could have together contributed to a "daisy chain of failures of multiple improperly designed or constructed parts or systems."
Titan was an implosion, so the pressure hull failed at some point, we just don't know what. While the Logitech controller is indicative of the decision making process, it's one component we can comprehensively rule out as causing the failure.
we cant rule that out yet! maybe someone played CoD on the way down, but the high latency made them ragequit, causing a high-quality, robust controller to be accelerated fiercly, piercing the crappy hull.
It's using the fact that it was a wireless controller used over Bluetooth as part of the evidence that they created a bunch of unnecessary points of failure.
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.
... 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.
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.
Just taking a guess here but the controller was probably brought up as evidence for how much they were cutting corners and disregarding safety and good sense, not as the cause of the failure
At this point filing a multi-million dollar lawsuit against OceanGate will be like trying to extract blood from a stone.
What tangible assets do OceanGate really have left to pay Nargeolet's estate? Their CEO (the maverick aerospace engineer who thought he was 'revolutionizing' the submarine industry by cutting corners) is dead, their only active submersible imploded, their reputation has been tainted by the fact that they've been selling billionaires what is effectively a carbon fiber coffin waiting to implode, and any angel investors have probably pulled out harder than a porn star on the verge of climax.
Even then, they may not even have a case. IANAL but in an age where every single tech and gaming company has been pushing through class action waivers and forced arbitration clauses in their Terms of Service, I get the feeling that any attempts at suing OceanGate will be thrown out of court by the waivers each passenger had to sign.
There is a sense of irony in people celebrating this disaster on social media because it means "five less billionaires in the world." No, this is potentially a massive L for us commoners, because it shows just how much corporate greed can destroy lives. If the rich can be screwed this badly by an unregulated corporation, imagine what corporate giants can do to people who can't afford lawyers.
from 29 minutes in. A last-minute adjustment before launch plugged in a thruster backwards; no protocol to check the behaviour prelaunch. They doscovered it when they got to the bottom.
Everyone's joking here but I've owned and used an F710 since 2009 and they are ABSOLUTE CRAP.
I'm not even joking but their range is like 3 feet in the BEST conditions and their USB controller is proprietary and doesn't even work with OTHER F710s.
Anyone who's used one for more than a few hours knows this.
Why do I still use mine? Well the hand feel is amazing and the weight is perfect, but everything else is terrible and shouldn't even be used for gaming.
I think mainly the wireless choice was for aesthetics, they were building experiences for billionaires and those assholes put way to much score in appearance.
The vast majority of the cause of the 3 mile island nuclear meltdown was a moisture soaked compressor pump completely unrelated to any of the safety or emergency systems. With complicated failures, the actual fault is not always easy to detect.
It's reasonable to think that the controller might have contributed to unexpected descent past safety levels, or prevented them from recovering when warnings appeared.
I've got two F710s and they're reliable enough. I wouldn't trust them in pro gaming though.
If I got in the sub and saw one of these used to steer it, I'd be very concerned. I know they're not really blaming Logitech; just taking one of these out of the plastic packaging and saying 'OK, now we've got steering and propulsion!' is not really a safety culture to get behind.
I own 3 of those.
They are not for PS or XBox but for mostly for PC gaming.
They are not Bluetooth, they come with their dedicated USB nano receiver.
I don't even trust them to win a championship in "F1 race stars", the arcade F1 game. The wireless is not reliable enough. They eat AA batteries like candy.
Absolutely agreed and I've had to replace the shoulder bumpers on mine twice now. ALSO the trigger traverse is RIDICULOUSLY LONG! Like I can fire an actual semi pistol faster and those have a five lb draw.
But man do they feel nice in the hand. No controller since the ps2 has felt like this to me.
Logitech has great lawyers. It's almost guaranteed that there a "this controller's intended use is only for ____" in their purchase agreement paperwork.
IMO that argument weakens their case. The controller was one of the least problematic things they did. Mechanical controls would have compromised the hull even more, so it was always going to be controlled electronically. I hope the complaint at least offers examples of better options and how those would have had any effect at all on hull integrity.
