Hi Frank,
I member the DC-2 doing joy flights from the Milperra Bridge corner. I went on it once, can't remember the cost, must have been a couple of 'quid' then.
The disappointment of the day was that instead of going Harbour Bridge return, he went to Cronulla return - ATC!!
He also had that very small 'Penguin' airframe, with what appeared to be a motor cycle engine, and he would start that up as a 'crowd teaser', then flog tickets to the waiting crowd for either the '2', or the Anson.
I had rides in both at various times.
Plus the yard up behind the RACNSW which was just chockas with all sorts of 'bits and pieces', inc. another DC-2 in camoflage, brown / green.
And the Me-109 up in the hangar roof, and all the other types stored, none too carefully, if I remember.....
And, not to omit the small 'Merry-go-Round' made from drop tank halves...
Cheers
