A brief history & photos
This airfield was the site of the original Aeronca factory, a stop on Charles Lindbergh's 1927 "victory tour", and a WWII bomber modification center. It lies in a valley at the confluence of the Ohio and Little Miami rivers, surrounded by hills, hence the "Sunken Lunken" nickname.
Annual flooding (especially the 1937 flood) led to the building of a dike on the perimeter.
