The President of the United States of America, authorized by Act of Congress, July 8, 1918 (amended by act of July 25, 1963), takes pleasure in presenting the Silver Star to Captain Donald Lester Heiliger (AFSN: FR-55023), United States Air Force, for gallantry in connection with military operations against an opposing armed force as an F-105 Pilot of the 388th Tactical Fighter Wing, Korat Royal Thai Air Base, Thailand, PACIFIC Air Force, in action over North Vietnam, on 30 April 1967. On that date, Captain Heiliger conducted the first night radar, low-level mission against one of North Vietnam’s most valuable and heavily defended railroad yards. Even under the best of conditions this mission would have been extremely difficult and dangerous. However, Captain Heiliger flew in the dead of night and in a single, unescorted aircraft. With complete disregard for his own safety, he continued his attack in spite of the threat of numerous missiles and through intense hostile anti-aircraft fire. By his gallantry and devotion to duty, Captain Heiliger has reflected great credit upon himself and the United States Air Force.
