Here is a little information on how to be king of the skies. Always fly the Comanche, why would you want to fly anything else. Pick any mission at any level, jump in the cockpit and take off. Fly as high as the Comanche will go, this will be 500 feet. Fly as fast as the Comanche can fly and bust up the place. If you do fill the need to cheat and get more ammo cause your busting everything in sight, use Ctrl+R to re-arm, re-fuel and repair. This must be a bug in the game because nothing can touch you. They will try but it forces their own destruction. Happy Hunting.
