The President of the United States of America takes pride in presenting the Distinguished Flying Cross (Posthumously) to Major Donald Joseph Reilly (MCSN: 0-61230), United States Marine Corps, for heroism and extraordinary achievement while participating in aerial flight as the Pilot of a UH-1E helicopter serving with Marine Observation Squadron TWO (VMO-2) in the Republic of Vietnam on 18 August 1965. Major Reilly was flying armed escort and combat missions in support of Operation STARLITE near Chu Lai when, while actively engaging insurgent communist (Viet Cong) forces during his first sortie, his aircraft was hit by intense ground fire necessitating an immediate emergency landing in the battle area. After hasty repairs, he was able to return the aircraft to the air base. Boarding a second aircraft, he courageously returned to the battle zone and, assuming the role of a forward air controller, boldly attempted to mark enemy positions for jet aircraft in order to relieve a friendly beleaguered amphibian tractor supply column. His aircraft was severely damaged by incessant enemy ground fire and his aerial gunner was wounded, requiring another return to the base. He boarded another aircraft and continued the mission. Arriving at the battle area, he received a request for emergency evacuation of three wounded Marines. In the absence of medical evacuation helicopters, he decided to land and rescue the casualties. He set down amid heavy fire, sustaining several hits to his aircraft. Because he had no communication with the ground forces and being uncertain of the extent of damage to his aircraft, he was forced to return to the air base. Major Reilly’s calm courage under fire and inspiring devotion to duty reflected great credit upon himself and the Marine Corps and were in keeping with the highest traditions of the United States Naval Service.
