Press F to launch. Without a lock, missiles fly straight; with LOCKED, they pursue that target. Keep the target near your gunsight to lock on.
Tanks, gun stations and SAM sites hold the ground below. They only open fire once you come close, and nothing they launch follows you — turn hard and it flies past.
Airspeed determines your climb ceiling. Too high: the nose drops and the aircraft descends. Crossing the map boundary fails the mission immediately.
Touch: use the flight stick and hold the weapon buttons.
