Where do you fine the AI?
offline practice under "practice missions"
It's not bad for AI, but I beat both of them each time on the first try and Im' not a p51 pilot. (actually made the AI auger twice

) It would be nice if you could select how many bad guys to fight. I think if it were more than one of them, they could be a real challenge for even the veterans.
I would say it could definitely teach newer players how to fight better. In fact if I was HTC, I'd make some sort of banner inside the game for people who first D/L the game prior to them signing up for their "2 weeks". This way they get a lil training before jumping into the MA's.
