Here a a few things I've noticed about the AI. I'd say I'm just an average AH pilot and I have a terrible time with the buffs and the fighters. I was even shot down by a group of AI Ju87s using their gunners
I have noticed that the AI fighters suffer from the very worst case of target fixation I have ever seen. I entered a 1 v 2*AI fight and
both AI stayed on the original target despite the fact that occasionally I was even closer to them than he was. At one point I was in front of one of the AI's guns and he ignored me and flew past to get to his original target. I was able to easily shoot down both because of their terrible target fixation.
Other things I've noticed: they seem immune to base ack and they never take collision damage despite the fact that they head-on attack a lot. I guess because the AI is perfect all collisions must be the players fault so the player gets assigned all the damage.
