Wolf and Apache have it right.
There has to be a concession to gameplay somewhere. Absolute realists must understand that. Unless you want a "one life" night, there is no way you can reasonably and fairly end the spawning defenders (assuming the attackers won't take the time to close the hangars).
If you send enough planes, and everyone does their job, there is little a defending side can do if they respond too late. Yelling that it is not realistic- well, I agree, maybe it isn't. But if you start down that path, what simulator does handle it "realistically", taking weeks of concentrated effort, massive artillery pounding, etc.
Hit the hangars, strafe the ack, and the goon is part of the first wave. When your fighters clear the air the goon sails in unmolested.
