sorry I have misunderstood you. But then: how could one change them? - I'm not sure if the airplanes in Vanilla are like the ones in Civ3? Maybe that would be a way... (have to admit, that I've never played Vanilla Civ4 in the modern age, because FFH was out at the time already, so...
). If this would be possible, they could be like a target/bombard unit with a range, which can be transported by spell waving units.
btw: your signature reflects my feelings - since FFH2, no other game has really driven me away from IT for long...
