Well, we could also add "grounded" due to weather or insufficient planes/pilots. We could also have a flag for 1 week if someone transfers to another unit. This way we can notice easily if something significant happened to other player's pilot.
It would make the scoreboard huge (and probably make it too difficult), but it would be cool to see small nationality flags, the image of the plane they're currently flying and the emblem of the unit, rank symbols. (Maybe even a red cross for pilots in hospital, prison bars for the captured - just little icons)
