1 March 1972: Lieutenant Colonel Joseph W. Kittinger II, United States Air Force, and 1st Lieutenant Leigh A. Hodgdon, were flying McDonnell F-4D-29-MC Phantom II serial number 66-7463, call sign Falcon 54. Along with a second F-4, they were assigned to a combat air patrol (MiGCAP) mission over northern Laos.
At approximately 2000 hours, Disco, a Lockheed EC-121T Warning Star airborne early warning aircraft, alerted Kittinger to the presence of several Mikoyan-Gurevich MiG 21 interceptors and gave him radar vectors toward the enemy aircraft.

Colonel Kittinger reported:
At approximately 18 miles the system broke lock but it was quickly reacquired. A slow left turn ensued to keep the dot centered. Altitudes were slowly increased from 8,200 feet to 11,500 feet. The Vc on the scope was extremely difficult to interpret; however, it appeared that we were not really overtaking the target, so the outboard tanks were dropped. Heading of the aircraft changed to approximately 360° at time of firing. At approximately 6 miles the “in-range” light illuminated, followed by an increase in the ASE circle. Trigger was squeezed and crew felt a thump as the missile was ejected; however, missile motor did not ignite. The trigger was squeezed again and held for approximately 3 seconds; however missile did not fire. Trigger was squeezed again and missile #3 fired. The missile made a small correction to the left then back to the right and guided straight away. Pilot maintained the dot centered.
Approximately 5 to 6 seconds after launch, detonation was observed. Almost simultaneously, two enemy missiles were observed coming from the vicinity of the detonation. Evasive action prevented more thorough observations of detonation. The flight turned to a heading of 210°, maintained 9,000 feet, airspeed 500 knots, and egressed the area.

Joseph W. Kittinger II is best known for his participation in experimental high-altitude balloon flights. On 2 June 1957, he ascended to 97,760 feet (29,490 meters) aboard the Project MAN-HIGH 1. On 16 August 1960, he reached 102,800 feet (31,333 meters) and then stepped off for the longest free-fall parachute jump—a record that would stand for 52 years.
Joe Kittinger flew 483 combat missions in three tours during the Vietnam War. He was shot down 11 May 1972, when his F-4D, 66-0230, was struck by a missile fired by a MiG 21. (Kittinger’s wingman shot down the MiG.) He and Weapons System Officer 1st Lieutenant William J. Reich were captured and held at the infamous Hanoi Hilton for the next 11 months.

MEDAL OF HONOR
CAPTAIN HILLIARD A. WILBANKS
The President of the United States of America, authorized by Act of Congress, March 3, 1896, in the name of Congress, has awarded in the name of The Congress, the Medal of Honor, posthumously, to CAPTAIN HILLIARD A. WILBANKS, UNITED STATES AIR FORCE, for conspicuous gallantry and intrepidity in action at the risk of his life above and beyond the call of duty:
As a forward air controller near Dalat, Republic of Vietnam, on 24 February 1967, Captain Wilbanks was pilot of an unarmed, light aircraft flying visual reconnaissance ahead of a South Vietnam Army Ranger Battalion. His intensive search revealed a well-concealed and numerically superior hostile force poised to ambush the advancing rangers. The Viet Cong, realizing that Captain Wilbanks’ discovery had compromised their position and ability to launch a surprise attack, immediately fired on the small aircraft with all available firepower. The enemy then began advancing against the exposed forward elements of the Ranger force which were pinned down by devastating fire. Captain Wilbanks recognized that close support aircraft could not arrive in time to enable the Rangers to withstand the advancing enemy onslaught. With full knowledge of the limitations of his unarmed, unarmored, light reconnaissance aircraft, and the great danger imposed by the enemy’s vast firepower, he unhesitatingly assumed a covering, close support role. Flying through a hail of withering fire at treetop level, Captain Wilbanks passed directly over the advancing enemy and inflicted many casualties by firing his rifle out of the side window of his aircraft. Despite increasingly intense anti-aircraft fire, Captain Wilbanks continued to completely disregard his own safety and made repeated low passes over the enemy to divert their fire away from the Rangers. His daring tactics successfully interrupted the enemy advance, allowing the Rangers to withdraw to safety from their perilous position. During his final courageous attack to protect the withdrawing forces, Captain Wilbanks was mortally wounded and his bullet-riddled aircraft crashed between the opposing forces. Captain Wilbanks’ magnificent action saved numerous friendly personnel from certain injury or death. His unparalleled concern for his fellowman and his extraordinary heroism were in the highest traditions of the military service, and have reflected great credit upon himself and the United States Air Force.

Captain Wilbank’s airplane was an O-1G Bird Dog, serial number 51-5078 (c/n 21983). It was manufactured as an L-19A by the Cessna Aircraft Company, Inc., at Wichita, Kansas, in 1951. The airplane was later upgraded to the O-1G configuration. It is a single-engine, tandem-seat light airplane which was developed from the company’s 4-place Model 170. The prototype, Cessna Model 305, N41694, made its first flight on 14 December 1949.
The O-1G is 25 feet, 9.5 inches (7.861 meters) long, with a wingspan of 36 feet, 0 inches (10.973 meters), overall height in 3-point position of 9.1 feet (2.8 feet). The airplane has typical empty weight of 1,716 pounds (778 kilograms), depending on installed equipment, and a maximum gross weight of 2,800 pounds (1,270 kilograms).
The O-1G Bird Dog was powered by an air-cooled, normally-aspirated, 471.239-cubic-inch-displacement (7.772 liter) Continental O-470-11 six-cylinder horizontally-opposed direct-drive engine with a compression ratio of 7:1. The O-470-11 was rated at 190 horsepower at 2,300 r.p.m., at Sea Level, and 213 horsepower at 2,600 r.p.m. for take off (5 minute limit). 80/87 octane aviation gasoline was required. The engine had a dry weight of 391 pounds (177 kilograms). The airplane was equipped with a fixed pitch two-blade McCauley propeller with a diameter of 7 feet, 6 inches (2.286 meters).
The O-1G had a maximum cruise speed of 85 knots (98 miles per hour/157 kilometers per hour), and never exceed speed (VNE ) of 165 knots (190 miles per hour/306 kilometers per hour). Its service ceiling was 20,300 feet (6,187 meters).
Cessna built 3,431 Bird Dogs between 1949 and 1959. Only about 300 are believed to remain airworthy today.

General Howell M. Estes, Jr., presents the Air Force Cross to Senior Airman Duane D. Hackney, 9 September 1967. (U.S. Air Force)
6 February 1967: That Others May Live. Airman 2nd Class Duane D. Hackney, U.S. Air Force, 37th Aerospace Rescue and Recovery Squadron, rescued the pilot of a downed aircraft and earned the Air Force Cross. He was the first living recipient of the Air Force Cross.
With more than 70 individual medals, Chief Master Sergeant Hackney was the most highly decorated enlisted man in United States Air Force history.
His citation reads:
Air Force Cross
“The President of the United States of America, authorized by Title 10, Section 8742, United States Code, takes pleasure in presenting the Air Force Cross to Airman Second Class Duane D. Hackney (AFSN: 16827003), United States Air Force, for extraordinary heroism in military operations against an opposing armed force while serving with the 37th Aerospace Rescue and Recovery Squadron, 3d Air Rescue and Recovery Group, DaNang Air Base, Vietnam, as a Paramedic (Pararescueman) on an unarmed HH-3E Rescue Helicopter near Mu Gia Pass, North Vietnam, on 6 February 1967. On that date, Airman Hackney flew two sorties in a heavily defended hostile area. On the first sortie, despite the presence of armed forces known to be hostile, entrenched in the vicinity, Airman Hackney volunteered to be lowered into the jungle to search for the survivor. He searched until the controlling Search and Rescue agency ordered an evacuation of the rescue crew. On the second sortie, Airman Hackney located the downed pilot, who was hoisted into the helicopter. As the rescue crew departed the area, intense and accurate 37-mm. flak tore into the helicopter amidships, causing extensive damage and a raging fire aboard the craft. With complete disregard for his own safety, Airman Hackney fitted his parachute to the rescued man. In this moment of impending disaster, Airman Hackney chose to place his responsibility to the survivor above his own life. The courageous Pararescueman located another parachute for himself and had just slipped his arms through the harness when a second 37-mm. round struck the crippled aircraft, sending it out of control. The force of the explosion blew Airman Hackney through the open cargo door and, though stunned, he managed to deploy the unbuckled parachute and make a successful landing. He was later recovered by a companion helicopter. Through his extraordinary heroism, superb airmanship, and aggressiveness in the face of hostile forces, Airman Hackney reflected the highest credit upon himself and the United States Air Force.”

The following is excerpted from Chief Master Sergeant Hackney’s U.S. Air Force biography:
Airman 2nd Class Duane D. Hackney, USAF, with jungle penetrator, aboard a Sikorsky HH-3E Jolly Green Giant, Southeast Asia, 1967 (U.S. Air Force)
“. . . His pararescue career began quickly. Three days after reporting for duty, Hackney, now an airman second class, flew his first combat mission. On his 10th mission, in April 1966, he was hit by enemy fire while pulling a wounded Marine pilot aboard his HH-3E Jolly Green Giant. Five times in the months ahead his helicopter was shot down. He earned four Distinguished Flying Crosses and 18 Air Medals for single acts of heroism. Then came Feb. 6, 1967 and the mission that would lead to the second highest award for heroism given by the U.S. Air Force.
“That morning he descended from his HH-3E to look for a downed pilot near Mu Gia pass, North Vietnam. He searched for two hours until bad weather forced a return to base. A few hours later, radio contact with the pilot was re-established and another rescue was attempted. This time, the severely wounded pilot was found. The wounded pilot hugged Hackney and said, ‘You’re beautiful.’
” ‘Hey man,’ said Hackney, ‘I’m not the stewardess.’
“Hackney carried the pilot back to the helicopter to begin their retreat. They had to hurry because it was rapidly becoming dark. Before they could clear enemy air space, anti-aircraft artillery struck the helicopter, filling the compartment with smoke and fire. Hackney strapped his own parachute on the pilot’s back and helped him get out the door. He found a spare, oil-stained parachute just as a second 37-mm antiaircraft shell ripped into the helicopter. Before he could buckle the chute, the Jolly Green Giant’s fuel line exploded, blasting Hackney through the door. Holding on to the chute with his arms, he managed to pull the cord before plummeting into the forest 250 feet below. The chute slowed his fall, but he still plunged 80 more feet to a rock ledge.
“Severely burned and pierced by shrapnel, Hackney managed to evade capture. When an A-1 Skyraider passed overhead, he fired a flare. A chopper mission was sent in and the rescuer was rescued. When he got back to Da Nang Air Base, he was told that he was the only survivor of the thwarted mission. Four other crew members and the pilot they had gone to save had died.
“For giving up his parachute and risking his own life, Hackney received the Air Force Cross. Hackney was presented the medal by Gen. Howell M. Estes Jr., the commander of Military Airlift Command.
“Hackney continued his distinguished Air Force career, retiring in 1991 as a chief master sergeant. In 1993, he died of a heart attack in his Pennsylvania home. He was 46 years old.”

ARVN soldiers run to board U.S. Army CH-21C Shawnee helicopters. (LIFE Magazine)
12 January 1962: The first helicopter assault, Operation Chopper, took place when 33 United States Army CH-21C Shawnee transport helicopters of the 8th and 57th Transportation Companies airlifted 1,036 soldiers of the Army of the Republic of Vietnam (ARVN) into battle against an insurgent Việt cộng (National Liberation Front) stronghold, approximately 10 miles (16.1 kilometers) west of Saigon. The landing zone was 150 yards by 300 yards and surrounded by tall trees.
A flight of U.S. Army CH-21C Shawnee helicopters over South Vietnam, 1962. (LIFE Magazine)
The Piasecki Helicopter Company CH-21C Shawnee was a single-engine, tandem rotor transport helicopter. It had a flight crew of three with one or two gunners, and could carry up to 20 soldiers under ideal conditions.
With rotors turning, the ship’s overall length was 86 feet, 4 inches (26.314 meters) and it was 15 feet, 9 inches (4.801 meters) high. The rotors were 44 feet (13.411 meters) in diameter and the fuselage was 52 feet, 7 inches (16.027 meters) long. The empty weight was 8,950 pounds (4,059.7 kilograms) and maximum takeoff weight was 15,200 pounds (6,894.6 kilograms).
The forward rotor turned counter-clockwise, as seen from above. (The advancing blade is on the helicopter’s right side.) The rear rotor turns the opposite direction. Normal operating speed for the main rotors was approximately 250 r.p.m. The counter-rotating rotors cancelled out engine torque, eliminating any need for a tail rotor.
The H-21 was powered by a single air-cooled, supercharged, 1,823.129-cubic-inch-displacement (29.875 liter) Wright Aeronautical Division Cyclone 9 863C9WD1 (R-1820-103) nine-cylinder radial, mounted inside the fuselage at midship, and drove the front and rear rotors in opposite directions through drive shafts and gear boxes. The Wright R-1820-103 engine was rated at 1,275 horsepower at 2,500 r.p.m., and 1,425 horsepower at 2,700 r.p.m., for takeoff. This direct-drive engine had a compression ratio of 6.80:1 and required 100/130 aviation gasoline. The engine was 4 feet, 0.50 inches (1.232 meters) long, 4 feet, 6.95 inches (1.396 meters) in diameter, and weighed 1,350 pounds (612 kilograms). Wright built 971 R-1820-103s from November 1950 through 1957.
The CH-21C had a maximum speed of 127 miles per hour (204 kilometers per hour) and a range of 265 miles (427 kilometers). It’s service ceiling was 19,200 feet (5,852.2 meters).

The Piasecki H-21 Workhorse was developed for the U.S. Air Force as an air base support and search and rescue helicopter in cold weather operations. A total of 707 were built for the U.S., France and Germany, as well as civil operators. 334 were built for the U.S. Army as the H-21C Shawnee, redesignated CH-21C in 1962.
Its performance in the hot and humid climate of Southeast Asia was limited, restricting the troop load to 9 soldiers. It was withdrawn from service in 1964 when the Bell HU-1A Iroquois began to replace it. All CH-21Cs were retired when the CH-47 Chinook assumed its role in 1965.
