Re: So what happened?
Well done on spouting complete bollocks and not knowing what you're talking about. But dont let that get in the way of making up conspiracy theories.
When working for NASA or on NASA funded Human Spaceflight projects you need to be an American. Fullstop. I can point to procurement documents that say that. Try and outsource around that and get caught and you would lose your preferential status, costing Boeing potentially billions. Not too mention the media and political fallout that would accompany it, and frankly not even Boeing management are that stupid.
As for comparing this with the 737, civilian aircraft have zero nationality requirements. You can outsource you're design and construction work wherever you want and indeed aircraft companies do, because it encourages those nations where the work is being carried out to buy Boeing aircraft and support their own local industry. Airbus does the same thing.
Even with military aircraft there are usually no nationality requirements. It's entirely based on getting a certain level of security clearance. Of course at the higher levels, you wont get the security clearance without being of the right nationalities, but that only applies to a small percentage of positions in the aircraft design.
As for your statement that "an engine is engine; the sub-contractor is none the wiser". All i can say is thank god you're not in charge of anything security related. Security through obscurity is what you're advocating and when your opponents (other nations in this case) are actively trying to find out more about your aircraft designs (and military aircraft specs are very high on the list of every intelligence services wishlist!), you really think that outsourcing like that is going to remain a secret? Intelligence agencies would have a field day with such an approach.
Whilst Boeing are definitely infected with Beancounter disease at the moment - cutting corners, failing to test critical items, and dropping the ball on quality - their are some rules you cant get away with cutting if you want to keep your cash cows. But by all means if you've got evidence that Boeing have been outsourcing their space program by all means - post it here. It would absolutely be newsworthy and El Reg would love to report it. But frankly you're talking bollocks.
