In this case I would say performing a symbolic drop (8 chutes?) on a sufficiently reduced airfield could be considered a capture/neutral/contested airfield, depending on damage and random factor (dice throw like in hex games. Think V4Victory). I think it would be enough of a feat to manage to succesfully get a transport over an airfield. It shouldn't be neccessary to bring systems to their knees with xx parachutes floating down.
