We live not very far from an Air Base so seeing military craft flying low is pretty common. The other day I spotted one I hadn’t seen before. Its RNZAF markings, and my poor visual discrimination, led me to misidentify it as an Orion. Thanks to @yorrike though I learned it was in fact a commercial Douglas DC3 and nothing to do with the airforce, in spite of its misleading markings: DC3 New Zealand Air Tour.
It beats me how it can get away with being marked as an airforce plane when in fact it isn’t.
