Now that folks have the ability to Skin aircraft with the terain editior, a huge amount of skins will be created.   Some will probably be very good, perhaps even better than those currently used in the game.  
Once a Huge Database of these are created,  I would enjoy seeing a skin choice in the Hanger.   These would still be embeded in the terain, but 3, 4 or maybe 6 differnet skins could be optional.     
It seem like a good option down the road.
