NC and TR have sidebars, VS have blade wings. Both types will probably obscure the view slightly, but none of the three will probably hurt flight effectiveness that much. All three will have much better view and awareness in 3rd person anyways, so it should be fine.
I would love to see an image inside the cockpit of all 3 just for comparison though. Hell, better yet, a video with the camera panning around the full view in every direction of all 3 cockpits. While I'm dreaming, just let us into the game so we can take a look for ourselves
