As for the Boeing SC facility location I believe this was a chess move by Boeing. The company wanted a second manufacturing plant in a right-to-work state. If Boeing had announced plans to build the SC facility there would have been a war in Seattle. However if a supplier 'chose' to build in SC then Boeing averts a PR disaster. Supplier quality-control issues accelerated the Boeing takeover.
So Boeing purposely choose a supplier knowing they would mess it up and thus would have to buy them out spending around a billion dollars on the facility? Add to that the stock price of both companies taking a hit and customers beating on their door demanding compensation for late deliveries? Is the fact that Beong won't make money on the aircraft till around ship 1000 part of their master plan as well?
