Staff Sgt. Jose Castillo reflects his inspiration for creating his "iFly" program at his desk, at the 537th Airlift Squadron, Joint Base Elmendorf-Richardson, Alaska, March 28, 2012. The patch in his left hand was a gift from his grandfather, who served in Vietnam and continues to inspire Castillo's career. The patch in his right hand comes from a training course for pilots that gave him the name "iFly." The wall of patches behind him has been collected throughout his career and, for him, represent his commitment to his job. Castillo serves as the aviation resource management noncommissioned officer in charge. While serving there, he created "iFly," which tracks training for pilots. (U.S. Air Force photo/Staff Sgt.
