Outsourcing of almost all of the components, DEI, moving the headquarters to Chicago and losing most of the Seattle work force who made it what it was, and worrying about the stock holder equity rather than safety and quality is what got Boeing in the mess it is in today...

Same happened with the airlines themselves.
