Well fair enough, electrovlas, no-one is hinting that Boeing builds anything other than super machines military or civil -but the programme you mention was certainly helped along in a very big way by Uncle Sam. Indeed the B707 probably would not have happened without it. I could give a string of other examples -NA Sabreliner exec jet, derivative of the T39 military trainer. (I'm baffled why you bring Galileo into it since the US GPS system is almost 100% funded by the Dept of Defense -we just want our own one in case you decide to switch it off one morning.)
...but of course these are just examples of the US aerospace industry standing on its two strong feet -and absolutely not subsidies!
