The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting a Silver Oak Leaf Cluster in lieu of a Sixth Award of the Distinguished Flying Cross to Major Floyd E. Heinzig (AFSN: FR-64830), United States Air Force, for extraordinary achievement while participating in aerial flight as an F-105 Thunderchief Pilot over North Vietnam on 9 September 1967. On that date, Major Heinzig was a member of a flight which was directed to strike Kep Airfield. Although severely hampered by extremely poor weather conditions and struck by intense, accurate anti-aircraft fire while rolling in, Major Heinzig successfully inflicted heavy damage on the target which was fifty percent obscured by clouds. The professional competence, aerial skill, and devotion to duty displayed by Major Heinzig reflect great credit upon himself and the United States Air Force.
