In my opinion, every plane should be a single pass in the style of CAS, rather than a loitering strike. It would make things more deterministic (which I'm a fan of). In which case, the strike would hit as normal if you moved the AA into the zone after the plane has shown up, but the window would be so small it wouldn't "really" matter much in terms of looking weird.
I used to think that having P47s as a single pass would be good, until I realized it would be the most powerful anti infantry off map in the game.
