Gotta be a military flight training base
- probable parade ground in central location
- lots of small aircraft
- no runways
Dora-9 lives in Oz, so searching RAAF training bases in WW2 with distinctive "V" shaped hangar layout brought up Uranquinty which was obviously designed by the same military genius, although it is not the one we want.
I think we are looking for an old RAAF base somewhere in Australia.
