The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting the Distinguished Flying Cross with Combat “V” to Major Leo Keith Thorsness, United States Air Force, for heroism while participating in aerial flight as an F-105F Pilot in Southeast Asia on 2 December 1966. On that date, Major Thorsness led a flight of four F-105 aircraft on a combat support mission in one of the most heavily defended areas in Southeast Asia. Despite marginal weather, intense, accurately directed hostile ground fire, and surface-to-air missiles, Major Thorsness with undaunted determination, indomitable courage, and professional skill made devastating attacks against surface-to-air missile sites in the primary target area. Disregarding his personal safety, Major Thorsness remained in the area for several minutes and exposed himself repeatedly to the hostile gun laying and surface-to-air missile guidance radars in order to call out warning on the hostile activity thereby permitting the F-105 fighter-bombers that he was supporting to enter and depart the target area fully aware of the enemy threat. The outstanding heroism and selfless devotion to duty displayed by Major Thorsness reflect great credit upon himself and the United States Air Force.
