Exmanman, you have a fair point indeed. Always a problem one can see, but if the frames on the static/runner line are not available to the public, the whole essence of the day is defeated a bit. If you have aircraft being towed, the teams must pre brief on what , how , when to deal with joe public if moving a frame. I was one of those on the entry point, not as bad as some others (thom manners had left them), but I can see what yo mean, 50 metre tape across it would not be hard.
