The National Airspace System (NAS) is the airspace, navigation facilities and airports of the United States...
Hmmm...right out of the gate there is a problem... If it had started with; The National Airspace System (NAS) is the authorized FAA controlled navigable airspace, navigation facilities and airports of the United States... Then that would help... Otherwise, just more over reach through inadvertent or purposeful ambiguous language... But that matters little... It's people's acceptance and lack of questioning of such things that is so very troubling to me... Where will that take us in the end?

Sorry for the brevity but typing on this phone is not conducive to further discussion but I hope at least one person out there in the vast ether can understand the very simple point(s)...
