also one way to destroy the 4 ships with Aders on them in F4 BMS is to fly supersonic at 40,000.00ft then shoot them one after the other (Expand view is recommended to avoid shooting the same target twice) and there is no need to wait for a pitbull. Just lock and unlock (in track while search mode). Once the last target is shot then do a very hard split S to fly away from them, but at 40,000.00 fts this last maneuver is usually not necessary.
