Here's a tricky one.
What actually WERE the aircraft registrations for the PNG:
TAA Cessna 182: I think it was VH-SBP? Was it the only one?
TAA Cessna 185: From this site I gather it was VH-SBU. Was it the only one?
TAA Aztec/s:
TAA Twin Otters: I know of TGR and TGS, any more?
What about the other TAA GA types such as the Queen Air (VH-TGA, B, C?)
Grumman Mallard (VH-TGA?)
