The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting a Second Bronze Oak Leaf Cluster in lieu of a Third Award of the Distinguished Flying Cross to Captain James Edwin Mack (AFSN: FR-63965), United States Air Force, for extraordinary achievement while participating in aerial flight as an F-100 Tactical Fighter Pilot over North Vietnam on 16 October 1967. On that date, Captain Mack was called upon to act as On-Scene Commander for a search and rescue operation for two downed airmen. Operating well within range of hostile antiaircraft artillery, Captain Mack spotted the aircrew, provided fighter cover for the pilots, and coordinated the many-faceted search and rescue efforts despite an aircraft problem that had driven cockpit temperatures to over 100 degrees for a sustained period of time. Ignoring the fatigue of a near six-hour mission and the extreme temperatures, Captain Mack stayed with his task until the men had been rescued by adeptly managing his fuel to absolute minimum conditions. His calm assessment and discharge of this responsible task while operating in an extremely hostile environment speak highly for this pilot. The professional competence, aerial skill and devotion to duty displayed by Captain Mack reflect great credit upon himself and upheld the highest traditions of the United States Air Force.
