Sky Battle © 1971 Chicago Coin.
Not one, but a squadron of 3 Jet Fighter Planes in sweeping aerial attack! Planes dive-climb-circle against a background of rolling clouds as player shoots to bring them down! When hit, each plane disappears in an explosive flash of light. When all 3 planes are hit, they re-appear for additional play and scoring!
Released in October 1971.
