It would be cool if ally air vehicles could takeoff and land on any captured island with an airfield, if it is a munitions plant, the vehicle could re-arm itself, or even park in the island's hanger for storage and later use. If it is an air chassis island, produced aircraft could fly themselves back to the carrier rather than needing a barge. This could also enable a new type of aircraft that would be an air transport that could pick up supplies from islands with airfields and bring them back to the carrier, as kind of a late-game barge.
