"Check Six! Air Combat in the Missile Era" "Check Six! puts you in the cockpit of a modern, high-performance supersonic jet fighter, commanding a flight of up to eight jets. Your mission is to provide 'Air Superiority' by clearing the skies of enemy fighters . . . You can simulate an air engagement from the wars of Korea, Vietnam, Middle East, or you can fly in a hypothetical scenario which you create!" This game of plane-to-plane combat was produced for the U.S. Air Force by Close Simulations as a part of Project Warrior. Avalon Hill would later print a revised version of the game under the name Flight Leader. Re-implemented by: Flight Leader
