Easter Eggs
All Enemy Fighters Are UFOs

Go to the password screen and enter 'NHDCDKPM'. Directly after completing the password, press start. Now choose New Game on the Main Menu. All of your enemies will now be Alien UFOs. These UFOs will shoot giant green balls at you. Also, on the cockpit view, the computer screen will show a UFO being shot in a game of Space Invaders, instead of the usual jet getting destroyed be a missile.


Enemies are all Red Barons

Go to the password screen and enter 'LCMLFLTC'. Directly after entering the password, press start and select New Game on the main menu. Now all of your enemies will be flying the "Red Baron" Fokker DR.111 triplane. Now on the computer screen in the cockpit view, when you hit a "Red Baron" with a missile, the screen will show a World War I fighter plane crashing into the ground rather than the usual jet being destroyed by a missile. The symbol for the enemy planes will also change to a WWI plane.
