It’s also the nature of the problems. It’s one thing for something to fail due to difficult to detect material defects or weird freak mechanical stresses. It’s entirely a different matter for things to fail because of just blatantly shoddy work or because the entire design is fundamentally broken. The kinds of failures Boeing has been experiencing are very much the latter not the former. They’re the sort of things that shouldn’t ever happen and yet they seem to have become the new normal for Boeing.
