I was an instructor at Barton 1980/81 (tall guy from dahn south) and was an active helper at that airshow. I remember meeting Tony Brown and Paul Eyte at that show and when subsequently joining Air 2000 took Tony on the jump seat on several occasions. Bob Screen who did the low flypast was the Chief Pilot. It was the only time I had been part of the preparations for an Airshow and it was an exciting and eagerly awaited experience by everyone. I remember me and my then girlfriend ( nowadays my wife ) taking Leo's girlfriend for medical treatment as she took the accident very badly. I remember Don Graham being very angry at the deaths of Alan and Leo and put the ban into effect pretty much immediately.
