Thought experiment: Let’s imagine that the Boeing design department 20 years ago had whipped out a perfect all-new airplane design and the MAX had never happened. I’ll call its replacement the “797 Pro Max.” It fixes all the things we all agree are unfortunate hacks about the 737 MAX and was designed freshly by people at least as competent as Airbus’s designers. Anyway, couldn’t this type of “so and so took off part X and forgot to properly bolt it on, and nobody made sure that removals were properly documented to ensure safety” problem happen exactly the same on a 797 Pro Max? I think the (very real) design problems really have little to nothing to do with their obvious process/manufacturing problems brought to light by the plug door incident.
