You have these massive manufacturing plants, including the worlds largest building, and tons of aircraft engineering talent built over 100 years in Everett. On the other hand, all of the executives are 2000 miles away? How on earth do they keep an eye on what's going on? The answer apparently is that they don't!
Also, they have been trying to move more manufacturing to South Carolina to avoid paying union wages... but again, there's over a century of experience building aircraft in the Puget Sound, and you can't easily replicate that elsewhere. There were constant stories of aircraft assembled in South Carolina being shipped to Everett where all of the work had to be redone, because everything was done wrong the first time.
Would you feel safe flying in a plane like that? You just have to hope the Everett workers caught everything the South Carolina workers screwed up.
