on radar? Say, at an airport?
Or would he be too small a target?
If he can be seen - what about large airports vs. small airports? More chance of being detected on one type of radar over another?
If he can be seen - can he outwit it, so to speak? By moving staight up, or very fast? Or flying very low? (Which isn't really an option, I suppose, if he's trying NOT to be seen, huh?)
I might be working on those dragons for you, Terry. Or I might not. Maybe I'm just idly curious.
