I'm very curious on how immersive would be an high altitude combat in SOW.
In Il2 series I found it very poor rendered; mostly due to wide FOW and the out scale maps (not 1:1) that rendered a too much aberrated horizon line.
Flight models it selves IMAHO are irrealistic, impossible to conduct an high speed combats with no altitude loss.
Many sources I read clearly show that during BoB interception and subsequents engagements were conducted at 20000ft 30000ft or above.
Many operational reports say things like: blue section detached from top cover formation to attack a two-ship formation of Ju88 2000ft below, after the attack was conducted they rapidly rejoined the main formation.
In Il2 when you loose your altitude, you are definitely isolated from your original package. At High altitude in Il2 seems to float in a too much instable atmosphere. In real WWII combat seems quite easy to perform a full-throttle climb and gain 2000 or 3000 ft.
I hope SOW would reproduce honestly this situations.
