still don't know in which universe one way clouds exist, where the other guy cant see you, but you can see him..
having people not be able to see each other will not promote combat.

I agree that this game was built for air to air combat between aircraft! I have felt since day one in this game, to improve and promote air to air combat is to present situations which attract lots of fighters and or fighter/bombers. I almost always title my posted missions with some actual mission which was flown in WW2. Example, Ba, Ba Black Sheep strike! In almost 100% of those missions, we get jumped by large numbers of fighters and now you have a actual air combat taking place instead of a "furball". When I say actual air combat, you have pilots trying to disrupt the bombing mission and you have other aircraft trying to destroy the attackers. In this situation, you have to do a little more than "spray and pray" to get a kill. Seldom do I see, sitting in the lead bomber, defenders applying enough converge angle to get a kill and stop the attackers.
While I don't fly fighters much because of bad eyes, I would offer this advice: When a attacker enters the bomber stream, forget chasing the guy and fly a heading to set yourself up for his second pass.
As far as attacking bombers, I believe the 11 O'clock to 5 O'clock pass through the bomber stream is the hardest for bombers and fighters to defend. Of course I am not a good fighter pilot because of my eyes, but maybe the attackers and defenders can comment on this method.
