[unfinished project] This game seemed like a natural for a web-app. Tons of aircraft data could be stored in config files and the turn sequence cycled screen-by-screen for ease of play. The flight model is not clearly defined in the rules (as I interpret them), and there was still a need to paste on specific maneuvers that the normal flight instructions could not accomplish.
Once the bomber raids are plotted and started, there is not much for the RAF player to do. So this app has collection raid plots that it selects from randomly. It then moves the raids turn by turn, while you, as the Luftwaffe player, attempt to discover it and attack.
