KADENA AIR BASE, Japan -- A KC-135 Stratotanker piloted by U.S. Air Force Col. Richard Tanner, 18th Wing vice commander, drives through water spray May 7, 2019, commemorating Tanner's final or fini flight at Kadena Air Base, Japan. For many aircrew, the fini flight is a way to recognize and honor fellow aviators as one who can now hang their hat with the many Airmen who have gone before them.
