I used Blender to create the iconic hangars, buildings and other airport objects. By layering actual photos onto the models, I could create a very realistic effect.
Here are several early models. (Click the Play button to manipulate the models):
The Aircraftsman Hangar (NE side of Zahns):
Amityville Flying School Operations Office:
Main Hangar:
Fuel Pumps:
Army National Guard Hangar:
Sig Uyldert’s Flying School:
Sunrise Drive-In:
(The drive-in was not part of the airport, but had been used as a visual navigation aid.)
