First Lt. Audrey McCabe escorts Haley and Zachary Tyrrell back to a shuttle bus Feb. 18 during Haley’s “Pilot for a Day” tour at Joint-Base Pearl Harbor-Hickam. “Pilot for a Day” is a program that allows children with severe illnesses to take a break from treatment to visit an Air Force base and learn all things aviation. Haley recently finished chemotherapy and overcame brain cancer in the process.
