You might try USDA.  Its Farm Service Agency (and predecessor agencies: ASCS, CSS) have been using aerial photography for more than 50 years.  The URL for its aerial photo lab is:

Subject: [NYHIST-L] Air Photos by the "Mason Flying Service"

I have been looking for air photos taken by photographers from airplanes in the Central New York region.
An early source of photos is "Mason Flying Service"  Air Photo from Geneva, NY.  the Geneva Historical Society tells me that the Mason Flying Service was no longer listed in the Geneva Directory by 1950.  I have not been able to locate anyone that knows what happened to them or where their negatives might be housed.
