I was there that night also and I like many others thought it was an engine failure and then I found out the reason why. I also remember the time when invitations were sent to a few riders from the then British League to an open meeting in Poland at the same track that would be hosting the World Final two weeks later, Ivan was the only one to accept the booking which gave him some timely practice at the track. He was using his head as he did at White City that night. Needless to say he went on to win another World Title there. What a man what a rider. Is he the greatest of all time ? I think so.
