Yes I remember that incident (I used to stand on the third bend)...vaguely recall the choice of music being played and the furore it created. There used to be a number of crashes on that area of the track because of the notorious adverse camber which used to catch a few riders out (although not in Richard's case as I seem to remember that there was a coming together between two riders?)
It became very obvious to me during one close season when I was helping with getting the track ready for the new season and becoming very aware of the track flattening out two thirds the way up to the fence. One rider who used it to his advantage, however, was Dag Lovaas who rode the line perfectly sweeping past opponents by sticking his rear wheel on the point of no return so to speak!
