Ivchenko / Man on Fence.
I dont know the rules as you guys obviously do, but I was with the Red Arrows (groundcrew) for a while a few years back and my understanding of the rules then were that passengers could not be carried on displays. Yet I noted that the back seat was occupied on one Reds aircraft on the Saturday display. Maybe the rules have changed - I dont know, but in the light of the Vampire tragedy it would appear to be common sense not to carry a passenger unless it was absolutely necessary, would it not?
