The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting a Bronze Oak Leaf Cluster in lieu of a Second Award of the Distinguished Flying Cross to Captain Lanny Thomas Gus Lancaster (AFSN: FR-63943), United States Air Force, for extraordinary achievement while participating in aerial flight as a Forward Air Controller and Pilot of an F-100 aircraft, while operating over North Vietnam on 20 March 1968. On that date, Captain Lancaster located, halted, and directed fighters against one of the most lucrative vehicle convoys ever sighted in North Vietnam. He stopped the movement of numerous vehicles with strafing passes. After he had expended all of his ammunition, he continued to thwart attempts by hostile forces to move the vehicles by making low level passes over the convoy, through intense hostile groundfire, until ordnance laden fighters arrived. His professional direction of the flights dealt the hostile forces a severe blow in their re-supply efforts and trapped numerous vehicles for attacks by later flights. The professional competence, aerial skill and devotion to duty displayed by Captain Lancaster reflect great credit upon himself and upheld the highest traditions of the United States Air Force.
