Yes, disable the bombers dropping on the ground.
Instead, lets be more realistic, make it where we can go into the hangar and choose
"Crazy shi-ite muslim car bomber" add a garage door to the tower, when all targets at the field are dead, the garage door swings up!, and out comes ten or so wild-eyed crazy arabians with lotsa TNT in the trunk! And you better watch out, cause they're headed for you, and fast!
