Bushranger,
I saw those aircraft in Vung Tau in 1969. OD paint job with Yellow Roos on the doors, I think (memory is a funny thing!) Nice to see some allies there in the thick of things. Great guys, great fighters, and kind of wild after hours. Saw a truckload of Aussies unload in a few seconds to help a mate out in a brief barfight. Glad those guys were on our side!
