This game simulates dogfights between fighters in WW2. The game is played in a number of "impulses", with faster planes getting to move more often. A maneuver can take several impulses to complete and is marked with a maneuver marker in the hex that shows the plane's final position. The object is simply to shoot the other players down before they shoot you down.
The basic game is relatively simple and reasonably realistic. (It has a unique system of simulating different maneuvers.) But there are many additional rules which add even more realism (and complexity): ammo and fuel limits, critical hits, pilot quality, spotting, multiple planes on each side, etc.
