BoB in mind? Proves my point, superiority in air isn't enough for warfare. IMO Luftwaffe didn't managed to match the variety in planetypes to allied AF's. Especially towards the end of war almost every plane german developed were aimed to kill buffs (which is quite understandable). At the same time allies had a (superior) plane for almost every other types of missions. But I still think it was the numbers that mattered. Not only in air, but in all areas.
