i dunno about you, but i'm a normal human and can rotate my torso and neck around a thing called a spine. my eyes work well too - neat thing called peripheral vision. if anything we're already more blind in AH in any plane than we ever would be in R/L. 
And in addition to that we have 2 eyes stereo vision, which means depth perception and also kind of enables us to see "through" thinner frames. One can try this with by placing an erect thumb half way between the eyes and the computer screen. The thumb does to cover any text, because each eye can see around it.
So, we cannot have the thing called "realism" on the computer screen, but we can evaluate what is the result of a simulated thinggy compared to the real thing. The 3D model may be exact, but an enemy plane can hide behind it on the computer screen, whereas in real life one would see the enemy all the time.
To me it is a question of principle and main goal... to make a simulation of WW2 planes (engineering approach)... or to make a simulation of WW2 pilots flying those planes, of WW2 air combat (more humanist[?] approach). How to balance between the "technical truth" and the "being there" sides of an issue?
