Thanks for the detailed feedback - really appreciate it. I think there is a bug when a Luftwaffe unit decides to return to base, the corresponding RAF unit goes instead - all the way to France! The sand table is spot on - I was trying to make it like those WW2 Battle of Britain movies will all the women calling out the movements as they are received. But I didn't have time to get my wife to record the samples - she was away the final weekend.
