Bombing tanks, in particular perk ones. I enjoy it when they call me a bomb tard as if the aerial component was an afterthought to the ground combat in Aces High.
edit: One more thing, I also enjoy acting like I'm going to bomb an airfield like a typical jabo P38 and suddenly reversing on the unaware attacker that was going to follow me nose low. You can almost taste their surprise and it is readily visible by the uncoordinated flight they suddenly display.
