U.S. Air Force Tech. Sgt. Sara Jo Danis, 18th Air Refueling Squadron boom operator, explains an air refueling operation to a civic leader out of Dyess Air Force Base, May 2, 2019. The air refueling flight was part of a civic leader tour to Wright-Patterson AFB, Ohio. The tour allowed the civic leaders to see several important facets of the Air Force mission, including an air refueling of a B-52 Stratofortress, an Air Force research laboratory tour, and a medical demonstration aboard a C-17 Globemaster III.
