hehe, I'm not really sure. I don't pay much attention to most a/c types of the others except squaddies. Come to think of it, ribman (squad mate) was flying an La7 at 1 point.
You know, I think thats why I enjoy fighting the knights the most. They seem to fly more of a variety of aircraft than the bishops, at least from an enemy point of view. Rooks may or may not fly a variety, I'm not sure.
