THe other night in the TA i was stuffin round in a 163 as you do. I adjusted the rear view so that a moved my head position as low and back as possible. At the maximum extent i could see through the rear of the aircraft and see what was behind me - like i got x-ray vision and could see through the aluminum skin of the aircrafts rear.
dunno if i was just me or my video card, but i aint seen it on any other model.
