...and btw, great Idea, Cavaliere :-)
Having the Opportunity to choose between 2 or 3 Planes as a Reward for becoming Ace would be really cool.

Next Idea:
How would you like to occasionally see a captured Enemy Plane flying? I remember the Photo, where "Nicht schiessen! Gute Leute!" (Don't shoot! Good Guys!) was painted all over a (british?) Plane in big Letters.

The Advantage: No new Model has to be created, only one or two Skins. Implementing the Planes into the Game should'nt be too much writing. Historical Research could be somewhat challenging, though.

I think this could be Fun, for it makes the Friend or Foe Identification a lot more difficult...
