Dora-9: Extensive use of Wikipedia can make one appear quite knowledgeable.
In this latest challenge, the lack of the centre red circle in the roundel indicates the aircraft was in the South East Asia Command in WW2 when the red circle was hurriedly removed after an American Wildcat shot down an Australian Catlaina because it looked like it had Japanese markings. The red circle was restored after the war ended, so this is an old photograph. I'm guessing that this airfield with its distinctive runways does not look anything like the photograph now.
Are we somewhere in Asia?
