CFS OPERATIONS brings you missions and campaigns for Microsoft's Combat Flight Simulator, which are based on actual, historical events. You've escorted bombers returning from Schweinfurt, chased down V1 Flying Bombs and sunk British ships in the Channel. Now fly the real thing - duel with the enemy in the thin, cold air five miles over Berlin, or dodge the flak and fighters as you attack the same ground targets the heroes of the air hammered over 50 years ago.
