if i am not mistaken, every kill needed to be proven either by a witness or gun cam film. when a pilot thought he might have just gotten a kill he called for others to check it out. when he landed he would file a report on the kill and witnesses would file their reports. then an officer would either accept or reject the kill claim based on the reports (i.e. do they prove that the enemy target was indeed destroyed). of course such a system does not remove "human error", but it does set some limitations for it.
undead reindeer cavalry got a reaction from Kineas in The Bouncing .50 cal - can it kill a tank?
