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 addition to a previously awarded Gold Star in lieu of a Fourth Award of the Distinguished Flying Cross to Captain (Transportation Corps) [then First Lieutenant] William B. Ailes (ASN: 0-5444332), United States Army, for heroism while participating in aerial flight as evidenced by voluntary action above and beyond the call of duty in the Republic of Vietnam on 17 March 1969. Captain Ailes distinguished himself while serving as Aircraft Commander of a CH-47C Chinook helicopter in Company A, 159th Aviation Battalion (Assault Support), in support of the THIRD Marine Division, near Vandegrift Combat Base, Republic of Vietnam. The mission was an emergency evacuation of Fire Support Base CUNNINGHAM, which was under an enemy mortar attack, and helicopters were being driven off. During a pause in the mortar fire, Captain Ailes made an approach to the base and landed. As soon as the troops started to board the aircraft, it was taken under enemy mortar fire which was adjusted to within ten meters of the helicopter. He remained on the ground until a load of twenty-two men were on board and departed the area. On the ascent, the aircraft was caught in a cross fire which hit the number one engine, rendering it inoperative. Due to the load, altitude could not be attained, and he turned back to the fire base to make a forced landing. Immediately after landing, the aircraft was again taken under enemy mortar fire. It was obvious that if the aircraft were shut down, it would be destroyed in a matter of minutes. Captain Ailes elected to attempt a single engine take off and fly back to Vandegrift after letting the troops off. He put his aircraft into a dive off the side of a cliff to regain the rotor revolutions lost on take off and soon established a small rate of climb. Despite enemy fire and marginal weather, he flew the aircraft to Khe Sanh, Republic of Vietnam, for repairs. Captain Ailes outstanding flying ability and devotion to duty were in keeping with the highest traditions of the military service and reflect great credit upon himself, his unit and the United States Army.
