Thad Middleton, 9 Air Refueling Squadron, commander, and Lt Col Jared Paine, 9ARS, operations officer, onboard a KC-10 Extender touchdown at Travis Air Force Base, Calif., on their final flight mission, June 4, 2015. Fini-flights are a traditional way to mark milestones in the career of aircrew, respected individuals of rank or repute, or a commander's departure to another command or retirement. Middleton's hometown is Port Huron, Mich., and Paine hails from Battle Ground, Wash. (U.S. Air Force Photograph by Heide Couch/Released)
