The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pride in presenting a Second Bronze Oak Leaf Cluster in lieu of a Third Award of the Distinguished Flying Cross (Posthumously) to Major Robert Edwin Brinckmann (AFSN: FR-42991), United States Air Force, for extraordinary achievement while participating in aerial flight as an F-105 Pilot near Kep, North Vietnam, on 8 August 1966. On that date, while piloting a specially equipped F-105, Major Brinckmann led his flight in an attack which resulted in the destruction of a hostile surface-to-air missile installation. The professional competence, aerial skill, and devotion to duty displayed by Major Brinckmann reflect great credit upon himself and the United States Air Force.
