The President of the United States of America takes pleasure in presenting a Fourth Gold Star in lieu of a Fifth Award of the Distinguished Flying Cross to Commander William Francis Span (NSN: 0-401287), United States Navy, for heroism and extraordinary achievement while participating in aerial flight as a jet attack pilot attached to and serving with Attack Squadron ONE HUNDRED SIXTY-FOUR (VA-164), embarked in the U.S.S. HANCOCK (CVA-19). On 1 October 1968, Commander Span was the leader of a 14-plane coordinated strike against a surface-to-air missile launching site near Vinh Son, North Vietnam. This heavily defended site has posed a serious threat to interdiction efforts in the area, and was considered a target of the highest importance. He carefully studied recently taken photographs of the area and obtained the latest meteorological data available. He then assigned specific aim points to each pilot in order to completely cover the target area and inflict the greatest possible amount of damage. As he approached the target, he led the entire strike group in a series of violent evasive maneuvers in order to deny the enemy gunners a suitable target. Quickly locating the heavily camouflages site, he led the strike group in a swift and devastating attack which completely destroyed the site, its missiles, launchers and radar vans. After recovering from his bombing run, and while maneuvering to avoid the 37-mm. flak directed at his aircraft, he circled the target to take photographs of the destruction with a hand-held camera. His efforts were directly responsible for the complete success of the mission. Commander Span’s courage and devotion to duty were in keeping with the highest traditions of the United States Naval Service.
