"July 1st, 1964 Vinh Long Province, South Vietnam. The radio crackles. Ground commanders are ordering Major Charles Kelly to abort his approach. The landing zone is too hot. Enemy fire is tearing through the trees. Kelly's reply is five words. Then he goes in anyway. Seconds later, a single bullet strikes him through the chest.
Between 1962 and 1973 pilots like Kelly flew roughly 496,000 medical evacuation missions in one helicopter the UH-1 Huey. They evacuated around 900,000 wounded soldiers. And when these elite Dust Off pilots first climbed into that aircraft what they felt wasn't just relief. It was revelation.
This is the story of what the most elite Medevac pilots in American history said when they first flew the helicopter that would rewrite the survival math of war. To understand what the Huey meant to these pilots you need to know what came before it. In Korea, Medevac helicopters were Bell H-13 Sioux aircraft. They carried wounded soldiers in Plexiglas pods strapped to the outside of the helicopter not inside. Outside.
Exposed to the elements beyond the reach of any medic. The pilot sat alone in a bubble cockpit with almost no protection. By the early 1960s, the Army was using the Piasecki H-21 Shawnee in Vietnam. Troops called it the flying banana. It had twin rotors and could theoretically carry 20 passengers. But in Vietnam's oppressive heat and humidity, it could barely manage nine.
The reciprocating piston engine, designed for Arctic operations, lasted about 200 hours in country instead of its rated 600. The H-34 Choctaw had the same problem. Its massive R-1820 radial piston engine could only deliver full power below 700 ft of altitude. Above that, you were gambling. Here's the technical issue.
According to the US Army's official medical history, piston engines in these helicopters produced only 1 horsepower for every 3 lb of engine weight. They guzzled high-octane aviation gasoline. They overheated constantly. And they left pilots flying what one instructor at Fort Wolters called Hiller the Killer. The wooden-bladed Hiller H-23 trainer was so underpowered, it could barely hover in hot Texas weather.
This was the world Dustoff pilots knew in 1962. Then the Huey arrived. The UH-1 Iroquois, universally called the Huey, was the first turbine-powered helicopter ever deployed to combat. It didn't use a piston engine at all. It used a Lycoming T53 turboshaft engine designed by Anselm Franz, the former chief engineer of the Junkers Jumo 004 jet engine from World War II.
That turbine produced roughly 2.4 times the horsepower per pound compared to the piston engines it replaced. It burned safer JP-4 kerosene instead of volatile aviation gasoline. And it completely changed what a helicopter could do. The UH-1H could carry six litters internally with a medic working on patients during flight. It cruised at 110 knots.
It had a 320-mi range, and it could hover out of ground effect at 8,200 ft altitude. The H-34 could barely hover out of ground effect at 2,400 ft. On January 21st, 1968, during a test in the Central Highlands at 95Β° F, an older UH-1D with the standard engine could lift 184 lb while hovering out of ground effect. The same airframe with the new T53-L-13 engine of the UH-1H lifted 1,063 lb.
That's nearly six times more useful payload in the same conditions. The Huey also had something else revolutionary. Wide, twin sliding doors that pilots often flew with completely removed. Patient loading time dropped from several minutes to under 30 seconds. When you're sitting in a landing zone taking enemy fire, 30 seconds versus 5 minutes is the difference between living and dying.
Major Patrick Brady joined the 57th Medical Detachment at Soc Trang in January 1964. He'd been flying the wooden-bladed H-23 trainer. In his memoir, Dead Men Flying, Brady wrote about his first time flying the UH-1B. Compared to our trainer, the wooden-bladed H-23, known as Hiller the Killer, this bird was a Rolls-Royce.
Brady went further. He described what flying the Huey actually felt like in a way no training manual ever could. In a chopper, and only in a chopper, man and machine truly bond. Anyone who has mounted a great and powerful horse knows the feeling. Feet on the pedals as in the stirrups, the cyclic and collective are the reins.
Two hands full of power, then lean forward for a great ride. He wrote about night dust-off missions with something close to reverence. The cool night air made the turbine even more responsive. The darkness brought a strange peace that only combat pilots understand. Michael Novosel had a different perspective.
He was 47 years old when he resigned his Air Force Lieutenant Colonel commission just so he could fly dust-off as a warrant officer. Novosel had flown B-29 bombers in World War II and Korea. Those aircraft had 2 in of armor glass in front of the pilot and half-inch armor plate surrounding the cockpit, the Huey had almost nothing.
In his official 1974 Army oral history, Novosel described the Huey's lack of protection compared to his B-29. I had the most rudimentary type of armor that was here and there, but not everywhere. In front of me, I had absolutely no armor with the exception of the chest protector. Brady put it more bluntly.
You were essentially sitting in a sack full of JP-4 fuel that ignited easily, but the power, the responsiveness, the ability to actually save lives instead of just transport bodies, that made it worth it. First coming here, I found some people who had actually flown with me and with Charles Kelly or family members.
Uh Bruce Zink is daughter's here and of my great, Wayne Allred, raise your hand Wayne if you still can. And uh what a great thrill it is for me to meet some of the people who flew with us in in Vietnam. Great thrill. Hard for me to think of a greater day in my entire life uh than this day and what we've seen happen to those Dust Off crews.
But I thought I would cover why we are here today. Charles Kelly. He came to Vietnam in January of '64 to command the 57th Helicopter Ambulance. Had five Huey helicopters with a specific mission to support and take care of only American forces throughout the whole country of Vietnam. The Huey was a magnificent bird designed specifically for medical evacuation then flying under the call sign Dust Off.
But there was no doctrine, no experience for its use in combat. All we had was a little bit from Korea and a little bit from World War II. The 57th Medical Detachment was called the original Dust Off. They sailed into Saigon Harbor on April 20th, 1962 aboard the USNS Croatan with five UH-1A Hueys. These were the first turbine helicopters ever deployed to combat anywhere in the world.
The call sign, Dust Off itself, was almost an accident. In 1963, the unit's second commander, Major Lloyd Spencer, picked it out of an unused call signs book at Navy Support Activity Saigon. The reason was simple. The rotor wash on dry Vietnamese ground literally blew dust over everyone present. The backronym came later.
Dedicated, unhesitating service to our fighting forces. Major Charles Kelly took command on January 11th, 1964. He instituted aggressive 24-hour a day night flying operations. He fought Pentagon brass to keep the red crosses painted on Dustoff helicopters when generals wanted to use them for cargo runs. Six months later, he was dead...read more πππ
