SOrry to whine, but my question still hasn't been answered... maybe I'll ask it a different way.
If there is no governing body in international waters (international waters not being owned by any one nation), and no one "owns" the airspace above international waters, what prevents me from going out to the very middle of the Atlantic Ocean and going up to FL410? WOuld the FAA say "We heard you were out in international airspace without a flight plan and since you are licensed through the FAA, we are going to take action against you?"
Would it be the equivalent of going out into international waters in the middle of the ocean, committing a murder, then my government arresting me for it?
I know that last scenario is ridiculous, but is that the basic gist of it?
