Look on the bright side here. What we have is a case of parts with some forged documentation. It’s not like planes had bananas instead of spark plugs. We had a supplier forge some of the very rigorous documentation we require for plane parts. And they got caught. Later than we might have liked, but they weren’t found out because some plane crashed.
Honestly, if you accept that there will always be some bad actors out there, this looks a lot like a system that’s working.
