In freeciv, the civ2 ruleset is missing an "Action setter" to enables or disables airlifts between two cities with airports until the discovery of Combined Arms. In Civ2, units may only airlift between cities when they both have airports AND the civilization has discovered combined arms. Not just with the discovery of Radio to enable Airports and the presence of the improvement in both of them.
