Crashing enemy ships
In mountainous terrain, land next to and remain close to a high cliff wall when enemy bombers or fighters are near and wait. They will crash into the mountains.
Eliminate fighter launches
Land on top of enemy drop-ships and destroy the hanger bays to eliminate the constant fighter launches.
Try landing on them and give them an up close and personal look at your Flak Cannon.
In Zone One, if you go behind the weapons armory there are dinosaurs that will explode if shoot them with anything besides the Vulcan Cannons or the Machine Pistols. If you do, they will just die.
The Flak Cannon works well at close range. Fire it at the first group of landing craft then use your pistol for the tanks at long range.
If you do not want to be seen by radar, fly over them as high as you can.
