I guess this is dangerously close to going off-topic (if it isn't already) but while I agree that a single pilot almost certainly could not change the course of events to earn a German victory, in a truly dynamic campaign, who is to say that other ahistorical, though plausible, events don't transpire on a larger scale to change the outcome?
For the Luftwaffe, what if there's a greater occurence of missions to destroy the radar sites or an even greater emphasis on airfield attacks? I'm no BoB historian but my understanding is that at one point the RAF was hanging by a thread and it doesn't seem that implausible to me that it could be possible for someone to get a German victory, however unlikely, if the right missions are generated.
For the RAF, what if there are more wasteful missions generated that needlessly puts their air assets at risk and in turn aids the Germans in further diminishing their ranks? On the other hand, what if RAF air crews, by luck or other means, inflict much heavier losses on the Luftwaffe and the BoB is effectively over sooner than it was in reality?
The very nature of a purely dynamic campaign means that no one's experience is exactly the same. To me, a good compromise would be to have a series of scripted, purely historical single missions for each side and also offer a dynamic campaign where anything could theoretically happen. The only constant would be that both sides start with whatever airpower they had in the Summer of 1940. What happens after that is up to the campaign generator, pilot performance (AI and human), and luck.
