You're right and should know! Do we still use them?
They were all give to various "Air Training Corps" upon retirement, with the arrival of the PC9 they are all loving cared for and kept in the original "Safety Orange" and white livery. Not sure if a few escaped to the wild, (need to check the register) but it wouldn't surprise me!
I was posted to ARDU out at RAAF Edinburgh (Adelaide, as you'd know) and we had a rotation for taking a flight in one of the many aircraft we had back then. A new bloke wanted to take a flight in the trainer Mirage we had then, he convinced one of the pilots to take him up and jump the queue for a flight!
The Mirage could pull high "G's" so a G suit had to be worn and these were bloody hot to wear, but the Mirage had A/C so not a problem. Well the "flight line" crew and the pilot dressed him up in the G suit and marched him out to the Mirage and straight past, to a CT4 parrot! The pilot was wearing shorts and a t-shirt and told him it was either now or never Well after ½ an hour being flown around in a winged greenhouse wearing his G suit, the poor bloke was completely spent, apparently they had to lift him out of the aircraft!
