If your ammo runs low, press 'CTRL' and 'X' during the game and watch the extra 500 rounds and 9 sidewinders clock up on the instruments. It maybe 'CTRL', 'L SHIFT', and 'X'. For a perfect landing, hold the 'HELP' key down about 10 to 20 feet above the runway.
If you get badly hit, don't bail out, instead swing round and head for home. Press 'HELP' and the '+' on the keypad and keep them depressed. The F16 will stay level and drop down. Switch to tracking mode and rotate to side view. Just before touch down, pitch up the nose and the plane will touch down successfully every time. Select "end mission" and you will be rescued even if you are in enemy territory.
