the Logitech F710 is a solid controller to get if you’re on a tight budget, but perhaps not exactly the type of equipment you want to stake your life on. […] Reviewers on sites like Amazon frequently mention issues with the wireless device’s connection.
The reporter, who followed an expedition of the Titan from the launch ship, wrote that “it seems like this submersible has elements of MacGyver jerry-riggedness.”
Pretty unlikely. It’s easy to dunk on them for the controller, but they apparently carried backups, and it’s nowhere near the most concerning thing about their operations. It’s much more likely that their extremely brittle carbon-fiber hull fatigued (again), their homegrown acoustic fatigue detection system didn’t detect it (or it did and they ignored it), and the ship was crushed in a fraction of a second.
