U.S. Air Force Col. Dan Walls, 23d Wing commander, sprays his two children with water after leaving his A-10C Thunderbolt II aircraft at Moody Air Force Base, Georgia, May 19, 2021. After conducting his final flight in the Air Force, Walls’s children greeted their dad by first spraying him with water as part of the “fini flight” tradition. (U.S. Air Force photo by Staff Sgt.
