But no, let's dump all these planes. Very ecological.
Let's do a complete redesign using a new parts. Because those won't have any problems.

That's the opaqueness of all of this that bothers most, yeah, as an engineer I can say with some confidence that this specific problem has been thoroughly dissected and analysed. What about the issues that aren't in the engineering-realm but in the business-realm? Have processes that allowed this failure to happen been fixed? Where was the root cause?
I'm pretty sure they also screwed up somewhere else. Most undergraduate engineers would not control a plane with a single sensor.
It's completely ridiculous and it was definitely a management decision to do that (there have to be somewhat decent engineers at boeing, because they build planes after all).
If you do something so fundamentally wrong, chances are you screwed up more than once...
