The half a millimeter error that nearly cost 469 lives

One post starts by presenting aircraft safety but from a software developer's perspective. That could maybe involve some (natural) degree of ignorance, but that could be often remedied...at least in the traditional engineering office setting, meaning that the software folks get daily exposure to aeroscience issues.
That's fine, but then another post professes the remedy to be a 'get tough' blanket policy...that don't work, usually, you can't legislate or 'rule-make' to get rid of ignorance.

the oversite on how the welding and drilling procedure works, i can understand that. attempting to fix the problem by.. not actually re-inspecting every engine?... hmmm.. sounds like the usual problems that end up screwing you over. no, you can't legislate your way out of that, but you can actually hold people accountable. every time i make a repair to a vehicle (and i work on a friends company's cars), i expect to get sued if the component fails, is found to be my fault, and someone gets hurt.
designing software to rely on a single sensor, with controls strong enough to override the pilot? fuck that. fuck the FAA and their laziness at validating their delegation of authority to make decisions for them.
there is very little actual ignorance left in most airplane crashes these days.
one of the recently in the pnw was a lock ring that was forgotten. the elevator trim assembly unscrewed all the way (vibration will do that) and the plane dive bombed right into the ocean. no redundancy on the control cables. hmmm... now who actually forgot the lock ring? we probably don't know.
