  • The OV-10A was the original Bronco model, and the only model flown by the U.S. Air Force. All variants of the OV-10 (except for the OV-10D) are essentially OV-10As with minor variations in equipment and little cosmetic changes. Many pilots feel that even though it is a simpler aircraft than the D model, the A model Bronco was a better-flying, more "seat-of-the-pants" type of airplane.
