While talking DC3s, I can add that MMA was the original registration of Mc Robertson Miller Airlines of W.A.
This aircraft started life as a C47 with the U.S. Marines in PNG then went to Perth as MMA and later returned to PNG as P2-ANS.
In 1977 it was purchased by Masling Airlines (Commuter Services) of Cootamundra and operated charter from Sydney and on occasions the route Sy-Wlm-Sy. It was given the registration VH-MWQ and when Masling started operating the Bandeirante in 1978, VH-MWQ was sold and went to Darwin where it operated for some time and the registration later returned to VH-MMA
