About Us

Harley Curless along with his wife, Kay, started Curless Flying Service in 1977 in Astoria, Il. Since then, Curless Flying Service has been treating crops throughout central Illinois for nearly half a decade.

Harley found interest in aerial application because of his love for flying and knowledge of farming. Harley didn’t grow up on a farm, but worked as a hired hand at Kay’s family farm as a teenager. He discovered his interest in flying after paying $10 to ride in a Cessna in 1975, and found himself with his pilots license 4 months later. Shortly after that, Harley realized that he needed to build a career out of flying. He mortgaged his house to purchase his first spray plane, a piper pawnee, and Curless Flying Service was born.

Currently, Curless Flying Service operates out of Astoria, Il with a fleet that contains aircraft with the most up to date technology, they provide aerial application of insecticides, fungicides, aerial seeding, and dry and liquid fertilizer.
