The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting the Distinguished Flying Cross to Major William Frank Harlin, Jr., United States Air Force, for extraordinary achievement while participating in aerial flight as a Forward Air Controller near Phu Cat, Republic of Vietnam, on 9 April 1972. On that date, he flew in support of an American ground unit that was pinned down by heavy automatic weapons fire, mortar fire and rocket propelled grenades. Despite limited visibility, a mountainous terrain and intense ground fire, he repeatedly dove his light unarmed aircraft low over the hostile positions to mark them for fighter aircraft. Because of his actions, many friendly lives were saved. The professional competence, aerial skill, and devotion to duty displayed by Major Harlin reflect great credit upon himself and the United States Air Force.
