<p>A Forward Air Controller (FAC) OA-10A on the flightline at Davis Monthan AFB. 77-0177 of 23rd TASS has the markings of 602nd Tactical Air Control Wing.
The photo was taken during the AMARC-tour in June 1988, when the bus did the operational platforms first.

The Hog is still there, but on the wrong side of the base: at AMARC.
