Notes

Script avoids directly changing the position data of the player ship to avoid several potential physics problems. Handles 3D targeting controls should proper models be included to the mission. Script also removes all hostile fighters and bombers that have passed the player ship and kills them. Radar-set-max-range SEXP should be used to prevent the targeting of the disposed ships.
