June is coming, and I have recently remembered this trip to St.Petersburg some years ago. It was early June, and I still have this picture taken on a boat on the canals where we both wear sunglasses (because it is a sunny night) and the time is 2330. Half an hour before midnight. Full sunshine in your face.
I'm writing this to suggest that the air ops model may require some modifications. Obviously, St. Petersburg and the areas north of it do not get much night time from mid May till later July. In the winter, there is scarcely any daylight in December and January. I think this should be reflected In the game.
How exactly? Not a clue, but certainly all air ops in December (till mid Jan?) ARE night-ops, and there is no night operations in June (till mid July?).
I understand that drawing a geographical "no-night-in-June line" would require bold and risky action, but then, the weather zones came to existence somehow, so perhaps not all is lost.
