You have brought back many memories of my days at Moorabbin Stationair!
I did my theory with Ron Robertson way back in 1986, there were 6 of us on the course, I often wonder what happened to the other 5! At lunch times we would wander around the airport poking our noses into hangars and aircraft along the flight line, no one ever asked what we were doing, it was the done thing back then.
I remember too the 3DB flying tadpole, it was no longer flying for the radio station at the time, but still wore the 3DB colours. It impressed me so much, I have dreamed of owning a 'twin seabee' since!
Cue music: Memories, light the corner of my eyes...
