My memories are a bit vague, but I remember that in Sep 69 I flew on what we called the QANTAS Charter SYD/SIN/SGN. We were in uniform, but had to take a civilian shirt with us so that when we got off the aircraft in Singapore we did not look like soldiers
We all had the same haircut, trousers and shoes and that lean look of fit 19 year olds. The civilian shirt was supposed to disguise the fact that we were military, but I don't think we fooled anyone!
Returned to Australia on the QANTAS Charter in Sep 70. Pretty sure we flew SGN/DAR/SYD.
Both the above flights were in daylight hours. There was always a certain amount of urgency at Tan Son Nhat to unload and reload the QANTAS Charter so that it spent as little time as possible on the ground.
Sorry, I don't have any pics of the QANTAS aircraft. Just a Pan AM one which I travelled on for R&R.
I went back a few years ago. Good comments by megan.
