Anti-Aircraft weapons may shoot at an aircraft at any point of its flight path from one edge of the field to its exit point. An aircraft must be off-board for 2 moves in order to turn around and attack again. If an aircraft has been damaged in a previous attack run, it will not return.

High altitude bombers are not put on the field, they may factored in as part of a pre-arranged bombardment attack at any point in a game.

Aircraft availability would depend on the scenario. The game designer might allocate a certain number of sorties to one side or the other. Players may have to pre-plot aircraft missions or they might have a forward air-controller on the field who calls for air-support when required. In a France 1940 simulation, the French and British players might have a 10% chance of receiving air-support during the game.
