William Sheary Mayberry
Bill had an illustrious career in the Air Force that began with cadet training in 1954. He received his wings the next year and was commissioned at Williams AF Base, AZ. He attained a BS in Aerospace Engineering at the Air Force Institute of Technology at the University of Colorado and rose to the ranks of Lieutenant Colonel. Lt. Col. Mayberry completed F-100 combat crew training at Cannon AFB, NM and 0-1 (oh-one) training at Hurlburt AFB, Fla. Shortly after, he was hand-selected to join an elite group of pilots known as the Mistys.
Bill would go on to fly over 200 clandestine missions over North Vietnam as a Fast FAC (Forward Air Controller). Casualties were high as Fast FACs were first in to mark enemy targets for the next wave of jets tasked with taking them out. Statistically, Bill shouldn’t have made it back home. Fortunately, he did, retiring from the Air Force in 1978 beginning his civilian career at Boeing as a certification engineer for the FAA. Bill would remain close with the Mistys for the rest of his life.
