Airstrike seems popular as a demonstration at shows, and I can see why. It's a very good implementation of the arcade game Scramble.
There are all the usual objects - rockets, fuel and ammo dumps, mine storm, enemy aircraft and airlocks to be blasted through with the famous scramble landscape of rugged terrain and tortuous tunnels. After completing a level. you enter a more difficult one.
Your ship has a very positive feel, with missiles and bombs operated by the joystick button and the space bar. Fuel, score, remaining bombs and missiles and ships are all shown during play. The balance of this game is a lesson to others.
