Clouds of War

From BoardGameGeek:

Clouds of War is a single-player card game that simulates the career of a pilot during the Great War. The components consist of 54 cards and a printed map on which the player tracks their progress. The goal of the game is to become an ace and earn enough Prestige points to finish the game as a heroic figure. Cards have multi-use and with them all situations in the game are resolved. Player uses his own cards face-down as they sport icons that activate his piloting skills. Campaign last for 2 years, and by the end of the game scoring Prestige will show what kind of a 'win' player managed to achieve.
