After following countless pages...It looks like we have and extra dimension to the art of aerial warfare.
To summarise..
1) Gaston, not having flown IL2 (or any real a/c ?) has put countless hours into documentary research
2) Gunz, Kettehunde, and others who has put the same hours into projects and the engineering side of flight, and maybe a bit more RL flight
3) The rest of us, who've built up many hours IL2 flight time (and RL time).
It sounds like the same argument that has existed during any conflict. Essentially all are correct to certain degrees. The Analyst, The Engineer, The Pilot.. all essential to obtaining the perfect aircraft in development.
The difference is that we all do not have a common foe (and there never will be), so we're divided in our approaches.
Gaston - You should get IL2-1946 and give it a go
