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 Major Roger Ingvalson, United States Air Force, for extraordinary achievement while participating in aerial flight as an F-105 Thunderchief pilot with the 34th Tactical Fighter Squadron, Korat Royal Thai Air Force Base, Thailand, in action over North Vietnam on 3 May 1968. On that date, Major Ingvalson led a flight of four F-105’s on multiple low angle strafing passes against a large North Vietnamese petroleum storage area. Attacking aggressively in the face of thirty-seven millimeter antiaircraft fire, Major Ingvalson’s flight, inspired by his outstanding example, destroyed eight hundred barrels of fuel. The professional competence, aerial skill and devotion to duty displayed by Major Ingvalson reflect great credit upon himself and upheld the highest traditions of the United States Air Force.
