That is also an interesting point, here is a picture of my friends legs after he had a ride in the winch operators position in the M578 on the Friday afternoon session in the arena. He was trying to us the camcorder, by Friday I had gained a bit of confidence in driving it at speed and it was now nice and muddy so it was also sliding around a bit, I managed to launch Ian up in the air, he came crashing down again and so did the seat back hiting him in the back of the legs and knocking him to the floor inside the turret. He did manage to keep hold of the camcorder whilst all this was going on, I will post the footage when I get it off him ! His wife who took the pictures when he got back (on the Monday after) was not impressed !!!
