Since Shoreham the display lines have gotten further from the airfields, I suspect you were a lot closer than those in the airfield proper. I was at Cosford and
found a location to take photographs which must have been 1/2 mile or more west of the runway, the display line was to the west of my location!! I got some good photographs but I pity anyone who was trying to get photos from inside Cosford.
