In my opinion, I think that would be dumb. If there would be an APD Airforce then to balance it they would have to let players buy either AA equipment or allow for weapons on aircraft. If there was AA launcher you wouldn't even be able to fly anywhere w/o being shot down buy a player with AA, it would eliminate the point of even using helicopters for supply runs and drug runs. If weapons were allowed on aircraft, everyone would buy a jet and arm it to the teeth with whatever they could put on it and RDM would be worse since there would be players gun running other who are just trying to drive somewhere. Also again it would ruin the point of using helicopters are transportation because there would be so many armed jets in the air that helicopters wouldn't be able to fly. If there was a APD Airforce and there was no balance then people would say it's unfair and it's very possible for the server(s) population to decrease. What would be cool though is a air unit that either enforces speed or is used for recon/transportation. I've only once seen a APD helicopter used as transport for other officers, never have I seen it used as it resource to follow and track anyone.
