303, the incident I'm talking about was definitely an F111, had a sit in the cockpit as well , it was based at the RAAF base near Newcastle. One of the low level flybys the pilot did a roll to the left and then to the right, very impressive so close to the ground. After the F111 did the low flyby and vertical the show commentator said that the F111 pilot would on the groundback at his base in the time it would take him to get down from the tower.
I am talking about the first airshow at Richmond in many years, they did have many more after that one, I know as I moved to that area the next year and never went to another one, the traffic chaos turned me off, Regards Frank.
P.S. I have some pics somewhere I'll see if I can find them , scan and post.
