There is one reason we think there are too many airplanes in SH4. That's time compression. Turn time compression off and play 24 hours for a few days and you'll see that air attacks are not too common.
Nobody will ever do that. But remember that at 1000x time compression, each minute is 16 hours and 40 minutes game time. Now crank it up to 8192x and do the math. Time compression ruins our interpretation of reality.
