If I might ask another question that may be relevant to Pat's scenario in particular: Is it possible to create events that return carrier aircraft to their originating carrier after a attacking a target? This would solve a major issue for modern naval scenarios, since the AI (surely a misnomer, given recent technological developments) is hopeless handling carriers. I experienced this when developing Sea Lion, where carrier planes left the carriers and rebased to cities whenever they were in range. The planes themselves ended up as essentially missile units, since they never returned to their carrier.
