The problem with UFO’s being in our military airspace is that pilots are being told to stand down from training missions because of the risk of collision.
Assume that they “are”…for the sake of argument.
The pilots of those craft would be training as well. And of course they would get priority. Their mission, in time of a global conflict, would take precedence over the “normal” AF.
The part of them being “ours” that pisses me off is the relatively fast transportation and energy generation that could be maximized if the tech were “released.”
