Shows that aerospace, read the development, certification and production of aircraft, is different from aviation, as in the use of said aircraft. Guess which side I am on.
But "Airspace access" IS controlled by the FAA? If I want to fly a plane into the sky over the US, I have to ask the FAA for permission. I'm trying to understand what you were alluding to in your previous comment.
That a) I know a lot more about the aircraft building bit than I do about the flying bit and b) I was wrong about what the FAA does when it comes to air traffic and flight plans. Reason being, once an aircraft is sold it usually isn't my job to worry about it anymore.
