CTW-5 aircraft are not allowed to do in-flight photography without approval. Other aircraft can unless it is limited due to instructions (ie. CTW-5, etc), SOP or due to some of the equipment being classified. If it is not classified then it is fair game. A lot of people think you can't photograph the cockpits, but you can. I ran into this problem a lot just from people not knowing or going by what they heard. Most the limits in the training commands are just for safety reasons.
