Interesting concept about a formation. Does the cpu only recognize the player controlled plane or do all 3 planes create their own boxes? It would reason that only one box would still be created.
On another note, it seems that bombers are faster, or my fighter is getting slower. I think, sometimes we get guys diving bombers enough to maximize their speed, making their boxes also increase. I seldom attack bombers co alt unless I am defending a nearby asset. The result is almost always predictably frustrating.
