The President of the United States of America takes pleasure in presenting a Gold Star in lieu of a Second Award of the Distinguished Flying Cross (Navy Award) to Captain (Transportation Corps) [then First Lieutenant] William B. Ailes (ASN: 0-5444332), United States Army, for heroism and extraordinary achievement while participating in aerial flight while serving with Company A, 159th Assault Support Helicopter Battalion, 101st Airborne Division (Airmobile) in connection with military operations against the enemy in the Republic of Vietnam. On 12 March 1969, Captain Ailes launched as Aircraft Commander of a transport helicopter assigned the emergency medical evacuation of casualties and the re-supply of a Marine unit occupying Fire Support Base NEVILLE on a mountaintop just south of the Demilitarized Zone. Undeterred by an overcast which reached well below the crest of the mountain, and guided only by a radio operator at the fire base who judged the position of the helicopter by the sound of its rotors, Captain Ailes skillfully maneuvered his helicopter up the side of the mountain with the sling cargo only five to ten feet from the tops of the trees. Upon reaching the defensive perimeter, he utilized a bunker as a reference point and pivoted his aircraft until the load was properly positioned, lowered the cargo to the ground, and released it. Landing his helicopter nearby, he quickly embarked the casualties, air taxied down the side of the mountain, and proceeded to the medical facility at the Vandegrift Combat Base. On three more occasions, Captain Ailes ignored the extremely hazardous flight conditions as he resolutely returned to the fire support base to deliver vitally needed cargo and evacuate the wounded. His courage, superior airmanship, and unwavering devotion to duty in the face of great personal danger were instrumental in the successful accomplishment of the hazardous mission and were in keeping with the highest traditions of the United States Armed Forces.
