General Howell Marion Estes, Jr., presents the Air Force Cross to Airman 1st Class Duane D. Hackney, 9 September 1967. (U.S. Air Force 070702-F-8733W-013)
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 enlisted 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.
In a 1968 interview, Duane Hackney described the events of 6 February 1967 in his own words:
“We scrambled out that morning,” he said. “We knew that a pilot was down in the jungles. There was voice contact but nobody had actually seen him.
“He was at the bottom of a pass, covered by three canopies of overgrowth. Clouds were low, making it difficult to see much of anything.
“I thought I saw something shining down there. I asked if I could go down and look. There was flak around us but it was falling short. I rode the end of a cable to the ground and picked my way through the jungle.
“I stumbled over rocks and some heavy growth and finally spotted footprints made by U.S. combat boots. But I couldn’t locate him. Late in the day we went back and this time I found him.
“We got him into the chopper okay and I was treating his abrasions when flak hit. There was smoke and fire everywhere. I put my parachute on him as fast as I could.
“I grabbed another chute for myself and barely had it on when the second round of flak poured in on us. I felt sharp pains. I went out the rear door and managed to pull the rip cord as I was blown out of the chopper at about 200 feet.
“I landed in a tree and somehow freed myself. My left arm and back were raw and bleeding. Funny, I was disappointed when I couldn’t reach into my pocket and yank out the dollar valentine I had bought. I was worried because I didn’t think I would be able to send it.
“I got the red smoke flare out, opened it and waited for my Air Force buddies to rescue me. In about half an hour they were picking me up. As we climbed into the air, I looked out and saw the flaming wreckage of the helicopter.”
Senior Master Sergeant Duane Dale Hackney, United States Air Force. (U.S. Air Force)

After Hackney fell from the helicopter, it was shot down by ground fire. All four remaining on board were killed.²
The Sikorsky HH-3E (Sikorsky S-61R) earned the nickname Jolly Green Giant ³ during the Vietnam War. It is a dedicated Combat Search and Rescue (CSAR) helicopter flown by the U.S. Air Force, based on the CH-3C transport helicopter. The aircraft is flown by two pilots and the crew includes a flight mechanic and gunner. It is a large twin-engine helicopter with a single main rotor/tail rotor configuration. It has retractable tricycle landing gear and a rear cargo ramp. The rear landing gear retracts into a stub wing on the aft fuselage. The helicopter has an extendable inflight refueling boom.

The HH-3E is 72 feet, 7 inches (22.123 meters) long and 18 feet, 10 inches (5.740 meters) high with all rotors turning. The main rotor has five blades and a diameter of 62 feet (18.898 meters). Each blade has a chord of 1 foot, 6.25 inches (0.464 meters). The main rotor turns at 203 r.p.m., counter-clockwise, as seen from above. (The advancing blade is on the right.) The tail rotor also has five blades and has a diameter of 10 feet, 4 inches (3.150 meters). The blades have a chord of 7–11/32 inches (0.187 meters). The tail rotor turns clockwise as seen from the helicopter’s left. (The advancing blade is below the axis of rotation.) The tail rotor turns 1,244 r.p.m.
The HH-3E has an empty weight of 13,341 pounds (6,051 kilograms). The maximum gross weight is 22,050 pounds (10,002 kilograms).
The Jolly Green Giant is powered by two General Electric T58-GE-5 turboshaft engines, which have a Maximum Continuous Power rating of 1,400 shaft horsepower, each, and Military Power rating of 1,500 shaft horsepower. The main transmission is rated for 2,500 horsepower, maximum.
The HH-3E has a cruise speed of 154 miles per hour (248 kilometers per hour) at Sea Level, and a maximum speed of 177 miles per hour (285 kilometers per hour), also at Sea Level. The service ceiling is 14,000 feet (4,267 meters). The HH-3E had a maximum range of 779 miles (1,254 kilometers) with external fuel tanks.
The Jolly Green Giant can be armed with two M60 7.62 mm machine guns.
Sikorsky built 14 HH-3Es. Many CH-3Cs and CH-3Es were upgraded to the HH-3E configuration. Sikorsky built a total of 173 of the S-61R series.

¹ The Cheney Award is a bronze medal awarded annually to honor acts of valor, extreme fortitude or self-sacrifice in a humanitarian interest performed in connection with aircraft (not necessarily military). It memorializes U.S. Army Air Service Lieutenant Bill Cheney, who was killed in action on 20 January 1918. The award was initiated by his family. It has been called the “Peacetime Medal of Honor.”
² The rescued pilot was a Forward Air Controller (FAC), Captain Lucius Lamar Heiskell, USAF, 23rd Tactical Air Support Squadron, 504th Tactical Air Support Group. He flew with the call sign “Nail 65.” Heiskell’s aircraft was a Cessna O-1F Bird Dog, serial number 57-2807. The HH-3E, “Jolly Green 05,” was flown by Major Patrick Hardy Wood and Captain Richard Abbott Kibbey. The flight engineer was Staff Sergeant Donald Joe Hall.
³ Beginning in 1928, an American food company began using a cartoon figure to advertise its “Green Giant” brand of canned peas. Eventually the mascot represented The Green Giant Company’s other canned and frozen vegetables. The character is now owned by General Mills. The nickname of the Sikorsky HH-3E Jolly Green Giant is derived from this advertising character.

Lieutenant Robert W. Crafton, U.S. Navy, and Captain Louis K. Keck, U.S. Marine Corps, with the record-setting Sikorsky HSS-2 Sea King. (FAI)
5 February 1962: A Sikorsky HSS-2 Sea King (later redesignated SH-3A) became the world’s fastest helicopter by establishing a Fédération Aéronautique Internationale (FAI) world speed record for helicopters of 339 kilometers per hour (210.645 miles per hour) over a 19 kilometer (11.8 mile) course between Milford and New Haven, Connecticut.¹ The pilots were Lieutenant Robert Wiley Crafton, United States Navy and Captain Louis K. Keck, United States Marine Corps. Both pilots were awarded the Distinguished Flying Cross and the American Helicopter Society’s Frederick L. Feinberg Award.
Having served the United States Navy for 45 years, the Sea King is still in service world-wide, most notably as the VH-3D “Marine One” presidential helicopter.
Sikorsky HSS-2 Sea King, Bu. No. 147xxx, modified for the speed record attempt. (FAI)
The Sikorsky HSS-2 Sea King was the first of the S-61 series of military and civil helicopters. It is a large twin-engine helicopter with a single main rotor/tail rotor configuration. The fuselage is designed to allow landing on water. The XHSS-2 made its first flight 11 March 1959. The helicopter was originally used as an anti-submarine helicopter.
The HSS-2 is 72 feet, 6 inches (22.098 meters) long and 16 feet, 10 inches (5.131 meters) high with all rotors turning. The helicopter’s width, across the sponsons, is 16 feet. The main rotors and tail can be folded for more compact storage aboard aircraft carriers, shortening the aircraft to 46 feet, 6 inches (14.173 meters). The empty weight of the HSS-2 is 10,814 pounds (4,905 kilograms). The overload gross weight is 19,000 pounds (8,618 kilograms).
The main rotor has five blades and a diameter of 62 feet, 0 inches (18.898 meters). Each blade has a chord of 1 foot, 6¼ inches (0.464 meters). The rotor blade airfoil was the NACA 0012, which was common for helicopters of that time. The total blade area is 222.5 square feet (20.671 square meters), and the disc area is 3,019 square feet (280.474 square meters). The tail rotor also has five blades and a diameter of 10 feet, 4 inches (3.150 meters). They each have a chord of 7–11/32 inches (0.187 meters). At 100% NR, the main rotor turns 203 r.p.m. and the tail rotor, 1,244 r.p.m.
The HSS-2 was powered by two General Electric T58-GE-6 turboshaft engines, which had a Normal Power rating of 900 horsepower, and Military Power rating of 1,050 horsepower; both ratings at 19,555 r.p.m. at Sea Level. The main transmission was rated for 2,000 horsepower, maximum. (Later models were built with more powerful T58-GE-8 engines. Early aircraft were retrofitted.)
The HSS-2 has a cruise speed of 125 knots (144 miles per hour/232 kilometers per hour) at Sea Level, and a maximum speed of 133 knots (153 miles per hour/246 kilometers per hour) at Sea Level. The service ceiling is 12,100 feet (3,688 meters). The hover ceiling at normal gross weight is 5,200 feet (1,585 meters), out of ground effect (HOGE), and 7,250 feet (2,210 meters), in ground effect (HIGE). The HSS-2 had a combat endurance of 4 hours and a maximum range of 500 nautical miles (575 statute miles/926 kilometers).
The Sea King was primarily an anti-submarine aircraft. It could be armed with up to four MK 43 or MK 44 torpedoes and one MK 101 nuclear-armed depth bomb. Other weapons loads included four MK 14 depth charges and four MK 54 air depth bombs.
In 1962, the HSS-2 was redesignated SH-3A Sea King. Many early production aircraft have remained in service and have been upgraded through SH-3D, SH-3G, etc. In addition to the original ASW role, the Sea Kings have been widely used for Combat Search and Rescue operations. Marine One, the call sign for the helicopters assigned to the President of the United States, are VH-3D Sea Kings. Sikorsky produced the last S-61 helicopter in 1980, having built 794. Production has been licensed to manufacturers in England, Italy, Canada and Japan. They have produced an additional 679 Sea Kings.

On the night of 4–5 February 1958, two Boeing B-47 Stratojet bombers from MacDill Air Force Base, Florida, were flying a simulated bombing mission. The second bomber, B-47B-50-BW serial number 51-2349, was under the command of Major Howard Richardson, USAF, with co-pilot 1st Lieutenant Bob Lagerstrom and radar navigator Captain Leland Woolard. Their call sign was “Ivory Two.”

After completing their simulated bombing mission, the B-47s were returning to their base in Florida.
On the same night pilots of South Carolina Air National Guard were on alert at Charleston Air Force Base with their North American Aviation F-86L Sabre interceptors. The fighters were fully armed with twenty-four 2.75-inch (70 mm) rockets. At 00:09 a.m., the pilots were alerted for a training interception of the southbound B-47s. Within five minutes three F-86Ls were airborne and climbing, with air defense radar sites directing them. In one of the F-86Ls, 52-10108, an upgraded F-86D Sabre, was 1st Lieutenant Clarence A. Stewart, call sign, “Pug Gold Two.”
The flight of interceptors came in behind the bombers at about 35,000 feet (10,668 meters). Tracking their targets with radar, they closed on the lead B-47, Ivory One, from behind. Ivory Two was about 1 mile (1.6 kilometers) in trail of Ivory One, but the airborne radars of the Sabres did not detect it, nor did the ground-based radar controllers.
This North American Aviation F-86L-60-NA Sabre, 53-1047, of the 444th Fighter Interceptor Squadron, Charleston Air Force Base, South Carolina, is similar to 1st Lieutenant Clarence A. Stewart’s F-86L-50-NA 52-10108, which was destroyed in the collision with the B-47, 5 February 1958. (U.S. Air Force)
At 00:33:30, 5 February, Lieutenant Stewart’s fighter collided with the right wing of Major Richardson’s bomber. The Sabre lost both wings. Lieutenant Stewart fired his ejection seat. His descent from the stratosphere took twenty-two minutes and his hands were frostbitten from the cold. He spent five weeks in an Air Force hospital. Pug Gold Two crashed in a farm field about 10 miles (16 kilometers) east of Sylvania, Georgia.
Damage to the right wing and aft fuselage of B-47B 51-2349. (U.S. Air Force)
The B-47 was heavily damaged. The outboard engine had been dislodged from its mount on the wing and hung at about a 45° angle. The wing’s main spar was broken, the aileron was damaged, and the airplane and its crew were in immediate jeopardy. The damage to the flight controls made it difficult to fly. If the number six engine fell free, the loss of its weight would upset the airplane’s delicate balance and cause it to go out of control, or the damaged wing might itself fail.
Damage to the right wing of B-47B 51-2349. (U.S. Air Force)
Major Richardson didn’t think they could make it back to MacDill, and the nearest suitable airfield, Hunter Air Force Base, Savannah, Georgia, advised that the main runway was under repair. A crash on landing was a likely outcome.
Damage to the aft fuselage and vertical fin of B-47B 51-2349. (U.S. Air Force)
With this in mind, Richardson flew Ivory Two out over Wassaw Sound, and at an altitude of 7,200 feet (2,195 meters) the hydrogen bomb was jettisoned. It landed in about 40 feet (12 meters) of water near Tybee Island. No explosion occurred.
The B-47 safely landed at Hunter AFB, but was so badly damaged that it never flew again. Major Richardson was awarded the Distinguished Flying Cross for his handling of the incident.
The missing Mark 15 has never been found and is considered to be “irretrievably lost.” It is known as “The Tybee Bomb.”
Clarence Arville Stewart was born 17 October 1934 at Drew, Mississippi. He was the son of John B. Stewart and Cleta R. Stewart. Stewart soloed a airplane for the first time at the age of 13 years. By the time he was 15, he had enlisted in the Mississippi National Guard. His actual age was discovered as his unit was preparing to deploy during the Korean War, and he was sent home.
After studying at the Mississippi Delta Community College at Moorehead, Mississippi, Stewart enlisted in the U.S. Air Force as an aviation cadet. On graduation from flight training, he was commissioned as a second lieutenant, United States Air Force Reserve, in 1956.
In 1958, Lieutenant Stewart married Miss Patricia Ann Hudson of Beaufort, South Carolina. They would have three children. Mrs. Stewart passed away in 2010.

Eight years after the mid-air collision with the B-47, Captain Stewart was in Thailand, assigned to the 421st Tactical Fighter Squadron, 388th Tactical Fighter Wing, based at Korat Royal Thai Air Base. Flying a strike mission on 2 June 1966, the the engine of his Republic F-105D-20-RE Thunderchief, 61-0160, exploded. Stewart ejected from his airplane for the second time in his career. The fighter bomber went down approximately 55 miles (89 kilometers) northeast of Korat. Captain Stewart was picked up by helicopter.
Captain Clarence A. Stewart
Stewart flew over 100 combat missions over North Vietnam. He was awarded the Silver Star for his actions of 1 August 1966: “While leading a flight of F-105s against an oil storage tank fabrication in North Viet Nam, Capt. Stewart was caught in a deadly cross fire from several SA-2 missile sites. He was turned back from the target three separate times by a total of eight SA-2 surface-to-air missiles, yet he persisted in his attack until his communication equipment was seriously damaged by an exploding missile and his flight had only recover fuel remaining. In the midst of the SAM barrage, Captain Stewart demonstrated his calm and courageous leadership by directing his wingman’s escape from an uprushing missile.” Major Stewart was awarded the Distinguished Flying Cross for another flight in which he destroyed two anti-aircraft sites.
The following year, Major Stewart was assigned as chief of the Aerial Review Control Team based at Eglin Air Force Base. The unit was responsible for controlling air shows, other than those flown by The Thunderbirds. (A junior member of the team was 1st Lieutenant Steve Ritchie, future fighter ace.)
Lieutenant Colonel Stewart retired from the Air Force in 1977. He died at Fort Walton Beach, Florida, 15 January 2015.

Designed by Boeing, the Stratojet was a high-subsonic-speed strategic bomber and reconnaissance aircraft, in service from 1951 until 1977. The B-47 could fly higher and faster than jet fighters of the time, and it was also highly maneuverable. The B-47 was flown by a two pilots in a tandem cockpit. A navigator/bombardier was at a station in the nose.
The Boeing B-47B Stratojet was the first full-production model. The B-47B is 106 feet, 10 inches (32.563 meters) long with a wingspan of 116 feet, 0 inches(35.357 meters), and an overall height of 27 feet, 11 inches (8.509 meters). The wings are shoulder-mounted with the leading edges swept aft to 36° 37′. Their angle of incidence is 2° 45′ and there is no dihedral. (The wings are very flexible, showing marked anhedral on the ground and flexing upward when in flight.) The B-47B has an empty weight of 78,102 pounds (35,426 kilograms), and a maximum takeoff weight of 185,000 pounds (83,915 kilograms). The maximum in-flight weight (after air refueling) was 221,000 pounds (100,244 kilograms).
From 1953 to 1957, the B-47B fleet underwent an extensive modification program which brought them up to the B-47E configuration.

The B-47B was originally powered by six General Electric J47-GE-11 turbojet engines in four nacelles mounted on pylons below the wings. All B-47Bs after serial number 51-2046 were equipped with J47-GE-23 engines. The airplanes built with the -11 engines were retroffitted with the -23s. Under the modification and upgrade program, the -23s were replaced by the J47-GE-25. This engine has a 12-stage axial-flow compressor, eight combustion chambers, and single-stage turbine. The J47-GE-25 is rated at 5,970 pounds of static thrust at Sea Level, at 7,950 r.p.m. and 1,250 °F. (677 °C.) turbine outlet temperature (TOT). (7,200 pounds of thrust with water injection). It has a maximum diameter of 3 feet, 1 inch (0.940 meters) and length of 12 feet, 0 inches (3.658 meters) and weighs 2,653 pounds (1,203 kilograms).
The B-47B was also equipped with solid-fuel rocket engines (JATO) located in the aft fuselage. These produced a maximum 33,000 pounds of thrust (146.8 kilonewtons) for 14 seconds.
The B-47B Stratojet had a cruise speed of 433 knots (498 miles per hour/802 kilometers per hour), and maximum speed of 528 knots (608 miles per hour/978 kilometers per hour) at 16,300 feet (4,968 meters). The service ceiling was 42,100 feet (10,333 meters) and combat ceiling 40,800 feet (12,436 meters).
The combat radius of the B-47B was 1,704 nautical miles (1,961 statute miles/3,156 kilometers with a 10,000 pound (4,536 kilograms) bomb load. Two jettisonable underwing fuel tanks could carry 1,780 gallons (6,738 liters) each. The maximum ferry range was 3,861 nautical miles (4,443 statute miles (7,151 kilometers).
For defense the B-47B was armed with two Browning AN-M3 .50-caliber machine guns in a remotely-operated tail turret, with 600 rounds of ammunition per gun. The co-pilot acted as the gunner using an optical sight. The machine guns were replaced by two M24A1 20 mm autocannons and radar control.
The maximum bomb load of the B-47B was 18,000 pounds (8,165 kilograms). The B-47 could carry two 7,600 pound (3,447 kilogram) Mark 15 two-stage radiation implosion thermonuclear bombs, each with an explosive yield of up 3.8 megatons, depending on the version, or a single 10,670 pound (4,808 kilogram) B-41 three-stage, 25 megaton bomb.
Beginning in 1953, the B-47B fleet underwent an extensive modification program which brought them up to the B-47E configuration.
A total of 2,032 B-47s were built by a consortium of aircraft manufacturers: Boeing Airplane Company, Wichita, Kansas; Douglas Aircraft Company, Tulsa, Oklahoma; Lockheed Aircraft Company, Marietta, Georgia. 399 of these were B-47Bs.
The Stratojet is one of the most influential aircraft designs of all time and its legacy can be seen in almost every jet airliner built since the 1950s: the swept wing with engines suspended below and ahead on pylons. The B-47 served the United States Air Force from 1951 to 1977. From the first flight of the Boeing XB-47 Stratojet prototype, 17 December 1947, to the final flight of B-47E 52-166, was 38 years, 6 months, 1 day.
