I know an A-10 cannon is a middle finger shoved up the ass of anything that moves, but can you really fight other airplanes with it?
Well, you could probably kill helicopters with an A-10. Other jets? Unless it's taxing off the runaway very doubtful, though I have heard weirder things
The first (MBB Bo 105) of two A-10 air-to-air kills during Gulf '91. The other was a Mil Mi-8. Fast movers could get in trouble if they get into the A-10 flight envelope. That big, unswept wing gives the A-10 a turning radius about half that of the F-16 and an all-aspect AIM-9 can ruin anyone's day.
Well, I'm certainly no expert in modern aerial combat, but it seems to me anyone dense enough to get into a dogfight with an A-10 deserves it. Punch it from a distance and move on. But, then again, by the time we arrive on the scene in force, air supremacy is generally in effect.
