Hints:

Terrain-masking and proper use of all available cover are critical to success in this game. Never fly higher than 100 feet and be prepared to dive behind trees or buildings at a moment's notice. Exposure equals death here, so never let them see you coming.

One handy way to stop quickly and drop behind cover is to jump immediately into the gunner's seat (F2 key) and press the H key (hover) and Minus key (lose altitude) in rapid succession. You'll find that the AI pilot can usually pull up and stop much more quickly than you can.

If you find yourself getting blown to bits on a regular basis, you should turn on "invulnerability" through the Preferences menu and then run a few test missions to perfect your terrain-masking skills.

When using your cannon against enemy infantry, switch off the TADS (Target Acquisition and Designation System) and use your Mark I eyeball instead. The computer always shoots low and will miss almost every time. If you're in the gunner's seat you should unlock the target (with the L key or joystick button 4) and shoot freehand
