Due to BF2's arcadiness you can also do some intersting maneuvers that will throw off pilots used to more realistic simulations. The aircraft in BF2 don't seem to have a strong preference to pitching up vs pitching down so you can do a negative g pushover with nearly the same force as a positive G. This results in the ability to do things like negative G barrel rools and outside loops with alarming speed(when I speak of barrel rolls I mean not only rolling about your axis but also pitching the nose up or down and using your rudder so that the aircraft tracks as if it is flying around the inner surface of a very large airborne barrel) This can make it very hard for an opponent to determine which way you will break when making evasive maneuvers. So instead of rolling 90 degrees and pulling back, try rolling and pushing forward instead. Many times the opposing pilot will already be pulling to follow you through the turn only to see you breaking in the opposite direction, by which time it is to late for him too maintain his position. Unfortunately I completely suck at the shooting part, especially with the guns. I can't seem to find a sweet spot that will take down an enemy aircraft in a reasonable amount of time. Although using your air to ground mode when tailing an opponent works very well when initiating a gun attack since most pilots don't look behind them often enough, and they won't even realize you are shooting at them until you score a few direct hits.
anyway what i wanted to say is nearly everytime when two pilots collid (in game) one of them blames the other. Whether it is friendly or enemy vs friendly. I really think that 99% of the time that aircraft collisions are not the fault of either pilot and it is an accident. 50% of the time i'm flying bomber i'm in rear view and can't avoid planes that are coming my way.
