CIA AIR OPERATIONS IN LAOS, 1955-1974
Supporting the “Secret War” In Depth and Truth
Thanks to William M. Leary and Members of Talking Proud
The largest paramilitary operations ever undertaken by the CIA took place in the small Southeast Asian Kingdom of Laos. For more than 13 years, the Agency directed native forces that fought major North Vietnamese units to a standstill. Although the country eventually fell to the Communists, the CIA remained proud of its accomplishments in Laos.
As Director of Central Intelligence (DCI) Richard Helms later observed: "This was a major operation for the Agency. . . . It took manpower; it took specially qualified manpower; it was dangerous; it was difficult." The CIA, he contended, did "a superb job."
Air America, an airline secretly owned by the CIA, was a vital
																																																																													component in the Agency's operations in Laos. By the summer of 1970, the
																																																																													airline had some two dozen twin-engine transports, another two dozen
																																																																													short-takeoff-and-landing (STOL) aircraft, and some 30 helicopters dedicated to
																																																																													operations in Laos. There were more than 300 pilots, copilots, flight
																																																																													mechanics, and air-freight specialists flying out of Laos and Thailand. 
During 1970, Air America airdropped or landed 46 million pounds of foodstuffs--mainly rice--in Laos.
Helicopter flight time reached more than 4,000 hours a month in the same year.
Air America crews transported tens of thousands of troops and refugees, flew emergency medivac missions and rescued downed airmen throughout Laos.
In addition, inserted and extracted road-watch teams, flew nighttime airdrop missions over the Ho Chi Minh Trail, monitored sensors along infiltration routes, conducted a highly successful photoreconnaissance program, and engaged in numerous clandestine missions using night-vision glasses and state-of-the-art electronic equipment. Without Air America's presence, the CIA's effort in Laos could not have been sustained.
A
																																																																													DISTORTED VIEW
																																																																													Air
																																																																													America's public image has fared poorly. The 1990 movie Air America is
																																																																													largely responsible for this. It featured a cynical CIA officer who arranged
																																																																													for the airline to fly opium to the administrative capital of Vientiane for a
																																																																													corrupt Asian general -- loosely modeled on Vang Pao, a military leader of the
																																																																													mountain-region-based Hmong ethnic group. 
The film depicts the CIA man as having the opium processed into heroin in a factory just down the street from the favorite bar of Air America's pilots. The Asian general, in return, supplied men to fight the war, plus a financial kickback to the CIA. Ultimately, we learn that the Communist versus anti-Communist war in Laos was merely a facade for the real war, which was fought for control of the area's opium fields.
Air America pilots in this film are portrayed as skilled at landing damaged airplanes, but basically as a wildly unprofessional menagerie of party animals, including a few borderline psychotics. These ill-disciplined airmen are not the villains of the story; they are merely pawns in a drug game that they either disdain or oppose outright.
A BUM
																																																																													RAP
																																																																													The
																																																																													connection among Air America, the CIA, and the drug trade in Laos lingers in
																																																																													the public mind. The film, according to the credits, was based on Christopher
																																																																													Robbins's book about the airline, first published in 1979 under the title Air
																																																																													America.  Although Robbins later claimed that the movie distorted
																																																																													his book,  it closely followed the book's theme if not its details. Both
																																																																													movie and book contend that the CIA condoned a drug trade conducted by a
																																																																													Laotian client; both agree that Air America provided the essential
																																																																													transportation for the trade; and both portray the pilots sympathetically.
Robbins provides factual details that the movie lacks. Citing Alfred W. McCoy's 1972 study, The Politics of Heroin in Southeast Asia, he relates how Air America helicopters collected the opium harvests of 1970 and 1971, then flew the crop to Vang Pao's base at Long Tieng in the mountains of northern Laos, where it was turned into heroin at the general's drug laboratory.
My nearly two decades of research indicate that Air America was not involved in the drug trade. As Joseph Westermeyer, who spent the years 1965 to 1975 in Laos as a physician, public health worker, and researcher, wrote in Poppies, Pipes, and People: "American-owned airlines never knowingly transported opium in or out of Laos, nor did their American pilots ever profit from its transport. Yet every plane in Laos undoubtedly carried opium at some time, unknown to the pilot and his superiors--just as had virtually every pedicab, every Mekong River sampan, and every missionary jeep between China and the Gulf of Siam."
If the CIA was not involved in the drug trade, it did know about it. As former DCI William Colby acknowledged, the Agency did little about it during the 1960s, but later took action against the traders as drugs became a problem among American troops in Vietnam. The CIA's main focus in Laos remained on fighting the war, not on policing the drug trade.
HOW IT
																																																																													BEGAN
																																																																													The story
																																																																													of the real Air America begins in 1950, when the CIA decided that it required
																																																																													an air transport capability to conduct covert operations in Asia in support of
																																																																													US policy objectives. In August 1950, the Agency secretly purchased the assets
																																																																													of Civil Air Transport (CAT), an airline that had been started in China after
																																																																													World War II by Gen. Claire L. Chennault and Whiting Willauer. CAT would
																																																																													continue to fly commercial routes throughout Asia, acting in every way as a
																																																																													privately owned commercial airline. At the same time, under the corporate guise
																																																																													of CAT Incorporated, it provided airplanes and crews for secret intelligence
																																																																													operations. 
In the 1950s, the CIA's air proprietary, as it was known in the lexicon of intelligence, was used for a variety of covert missions. During the Korean war, for example, it made more than 100 hazardous overflights of mainland China, airdropping agents and supplies.
SUPPORTING
																																																																													THE FRENCH
																																																																													CAT also
																																																																													became involved in the French war against Communist insurgents in Indochina. In
																																																																													April 1953, the French appealed to President Eisenhower for the use of US Air
																																																																													Force C-119 transports and crews to fly tanks and heavy equipment to their
																																																																													hard-pressed forces in Laos. "Having such equipment," the French
																																																																													emphasized, "might mean the difference between holding and losing
																																																																													Laos." 
While reluctant to commit American military personnel to the war in Indochina, the Eisenhower administration was anxious to assist the French. This led to a decision to use CAT pilots to fly an airlift in US Air Force-supplied C-119s. In early May, a group of CAT personnel arrived at Clark Air Force Base in the Philippines for 72 hours of concentrated ground and flight school on the unfamiliar C-119s. On 5 May, they flew six of the transports, now bearing the tricolored roundels of the French Air Force, to Gia Lam airbase, outside Hanoi.
Operation SQUAW began the next day. It continued until 16 July, with CAT pilots making numerous airdrops to French troops in Laos. With the waning of the Vietminh offensive, which was due more to the weather than to French resistance, the CAT crews were withdrawn.
The war in Indochina, however, continued to go badly for the French. In November 1953, French paratroopers occupied Dien Bien Phu in northwestern Vietnam, 10 miles from the Laos border, and established an airhead. Gen. Henri Navarre, the French military commander, wanted to lure the Vietminh into a setpiece battle in which superior French firepower could be used to good effect. Among the many mistakes made by the French in placing their troops 220 miles from Hanoi was their miscalculation of the air transport resources needed to keep their isolated forces supplied. Col. Jean-Louis Nicot, head of the French Air Transport Command in Indochina, lacked sufficient aircrews to meet the Army's demands. Unless additional assistance could be obtained, the French garrison could not be kept supplied.

In early January 1954, Washington alerted CAT for a possible return to Indochina. Under a contract signed with French authorities on 3 March, CAT would supply 24 pilots to operate 12 C-119s that would be maintained by US Air Force personnel. Operations from Hanoi's Cat Bi airfield to Dien Bien Phu got under way just as the Vietminh began their assault on the French position. Between 13 March and the fall of Dien Bien Phu on 7 May, CAT pilots flew 682 airdrop missions to the beleaguered French troops. One plane was shot down in early May, and the two pilots were killed; many other C-119s suffered heavy flak damage, and one pilot was severely wounded.
The C-119 went on to see extensive service in French Indochina, beginning in 1953 with aircraft secretly loaned by the CIA to French forces for troop support. These aircraft were generally flown in French markings by American CIA pilots often accompanied by French officers and support staff.
The C-119 was to play a major role during the siege at Dien Bien Phu, where they flew into increasingly heavy fire while dropping supplies to the besieged French forces. The only two American pilot casualties of the siege at Dien Bien Phu were James B. McGovern, Jr.("Earthquake McGoon") and Wallace ("Wally") A. Buford. Both pilots, together with a French crew member, were killed in early June, 1954, when their C-119, while making an artillery drop, was hit and crippled by Viet Minh anti-aircraft fire; the aircraft then flew an additional 75 miles east into Laos before it crashed.
CAT operations continued in Indochina after the fall of Dien Bien Phu. Between mid-May and mid-August, C-119s dropped supplies to isolated French outposts and delivered loads throughout the country. CAT also supplied 12 C-46s for Operation COGNAC, the evacuation of civilians from North Vietnam to South Vietnam following the signing of the Geneva Agreement on 21 July 1954. Between 22 August and 4 October, CAT flew 19,808 men, women, and children out of North Vietnam. It also carried members of the CIA's Saigon Military Mission north of the 17th parallel. Attempts by the CIA to establish stayehind paramilitary networks in the north, however, proved futile.
CONCERN ABOUT LAOS
The Geneva Conference of 1954, in addition to dividing Vietnam at the 17th parallel, confirmed the status of Laos as an independent state. The nation would be ruled by the Royal Lao Government from Vientiane on the Mekong River. Members of the pro-Communist Pathet Lao would regroup in the northern provinces of Sam Neua and Phong Saly pending integration into the central regime. The French were allowed to maintain a small military presence in the country to train the Royal Lao Army (FAR).
Laotian independence suited the policy of the United States, so long as the government remained non-Communist. Laos represented one of the dominos in Southeast Asia that concerned President Eisenhower and Secretary of State John Foster Dulles. Although the country had little intrinsic value, its geographical position placed it in the center of the Cold War in Southeast Asia. If Laos fell to the Communists, Thailand might be next, according to the domino theory. And the collapse of Thailand would lead to Communist domination of Southeast Asia--and perhaps beyond. 12
US Aid
																																																																													Under an
																																																																													agreement signed in 1950, the United States had been supplying economic and
																																																																													military aid to Laos. Following the Geneva Conference, Washington decided to
																																																																													expand this program. In January 1955, it established the United States
																																																																													Operations Mission (USOM) in Vientiane to administer economic assistance. At
																																																																													the end of the year, the Programs Evaluation Office (PEO)--staffed by reserve
																																																																													or retired military officers and akin to a Military Assistance Advisory
																																																																													Group--was set up within USOM to handle military aid. 
CAT soon became involved in USOM's aid program. In July 1955, USOM officials learned that a rice failure threatened famine in several provinces in Laos. Because a number of these areas were in remote, mountainous regions, airdrops would be the only feasible means to delivering essential supplies of rice and salt. Three CAT C-46s arrived at the northeastern railhead of Udorn, Thailand, on 11 September to begin the airlift. By the end of the month, CAT had flown more than 200 missions to 25 reception areas, delivering 1,000 tons of emergency food. Conducted smoothly and efficiently, this airdrop relief operation marked the beginning of CAT's--and later Air America's--support of US assistance programs in Laos.
CAT's permanent presence in Laos began on 1 July 1957, when CAT pilot Bruce B. Blevins brought a C-47 to Vientiane to service a new contract with the US Embassy. Blevins found flying conditions primitive in Laos. At least Vientiane had a pierced steel plank runway and the only control tower in Laos. Elsewhere, he usually landed on dirt strips that had been built to support Japanese fighters during World War II.
There were no aeronautical charts available, so he had to use French topographical maps. The only radio aid to navigation in the country was a 25-watt nondirectional beacon at Vientiane that was operated by employees of Air Laos, the country's commercial airline, who turned it on when it suited them.
Between 1957 and 1959, the unstable political situation in Laos led to a growing American presence in the country as the United States increased its support of the FAR. Air America, the name changed on 26 March 1959, primarily to avoid confusion about the air proprietary’s operations in Japan, provided essential transportation for the expanding American effort in Laos.
For the record, the State Department designated Air America as the primary SAR in 1964, obligating it to do this job. President Kennedy had earlier instructed the Marines to provide HH-43 Husky helicopters under Operation Millpond in 1961. The US military was not allowed to fly into Laos for SAR operations during these years.
Prior to 1964, the USAF Air Rescue Service (ARS) could not do the job for a combat situation. In fact, the ARS leadership felt it did not have a combat mission, its crews were not trained for such a mission, and its aircraft were not capable of providing effective retrieval in the dense jungles or mountain areas. Their primary vehicle was the Husky HH-43. As an aside, the HH-43 did become an important SAR vehicle in Indochina over time, known as the “Pedros.”
The airline's C-47s and C-46s passed more frequently through Vientiane to fulfill urgent airdrop requests. Blevins also was kept busy, landing throughout the country and making numerous airdrops to isolated FAR posts. He developed an especially close relationship with a CIA case officer who had arrived in October 1958 and who was assigned to support neutralist Capt. Kong Le's parachute battalion. The case officer frequently called on Blevins to carry personnel and supplies.
The summer of 1959 saw the introduction into Laos of a US Special Forces Group, codenamed Hotfoot, under the command of Lt. Col. Arthur "Bull" Simons. Twelve Mobile Training Teams took up duties at Vientiane, Luang Prabang, Savannekhet, and Pakse. The appearance of the Americans coincided with the outbreak of fighting between the FAR and Pathet Lao. In light of these developments, CIA officials in Laos requested additional air transport resources.
INCREASING
																																																																													AIR SUPPORT
																																																																													In August
																																																																													1959, CIA headquarters ordered its air proprietary to send two pilots to Japan
																																																																													for helicopter training. Robert E. Rousselot, vice president for operations,
																																																																													remembers being called into President Hugh L. Grundy's office in Taipei and
																																																																													shown the message. The requirement had "come out of the blue." He
																																																																													assumed that the CIA had a special operation in mind that called for the use of
																																																																													a helicopter and that it would be "a one-time deal." Little did Rousselot
																																																																													realize that this would be the beginning of a major rotary-wing operation in
																																																																													Laos. 

Eventually, four CAT pilots were trained on US Air Force H-19A helicopters in Japan and the Philippines. The CAT contingent did not reach Laos until March 1960. Due to the operating limitations of the H-19s, the underpowered helicopters could fly only at lower elevations in the country. Generally, they were used to carry CIA case officers to meetings in outlying areas and to distribute leaflets during elections.
By June 1960, it had become clear that helicopters would form a permanent part of Air America's operations in Laos. It was equally apparent that neither the underpowered H-19s nor the inexperienced Air America rotary-wing pilots could do the job. Both Rousselot and the CIA recognized that better equipment and properly trained pilots were needed to accomplish the mission. Rousselot hired four experienced US Marine Corps helicopter pilots who obtained their discharges in Okinawa to fly the H-19s. Later in the year, the CIA arranged for the Marine Corps to transfer four UH-34 helicopters to Air America to replace the H-19s.
THE
																																																																													HELIO COURIER 
																																																																													At the
																																																																													same time that Air America was trying to develop a rotary-wing capability in
																																																																													Laos, the company also was taking steps to introduce STOL aircraft into the
																																																																													country.  Maj. Harry C. Aderholt, a US Air Force detailee with the CIA,
																																																																													had supervised the development of the Helio Courier while serving with the
																																																																													Agency’s air branch. 
Convinced that the aircraft could survive the short, rugged airstrips often found in remote areas, he became the foremost advocate for Air America's adoption of the Helio Courier.
Air America obtained a Helio for trials in Laos in the fall of 1959. The STOL program got off to a poor start. The Helio's engines proved temperamental, frequently developing vapor locks on starting. Mud, rocks, and gravel tended to block the aircraft's crosswind landing gear. The rudder needed modification so that it would not jam. Also, the first pilots who flew the airplane were used to multiengine transports and did not receive adequate training on an airplane that demanded special handling techniques.
 
														Air America came close to abandoning the Helio. It was saved by Aderholt, who believed in the aircraft’s capability and was determined to see it work, and by Rousselot, who feared that the CIA would give the STOL mission to a rival company--Bird & Son--if Air America proved incapable of doing the job.
Early in 1960, Rousselot assigned Ronald J. Sutphin, a talented light-plane pilot, to the project. Both Aderholt and Rousselot agree that it was Sutphin’s skillful demonstration of the extraordinary capability of the STOL aircraft that led the CIA to greatly expand the program.
SUPPORTING
																																																																													THE ANTI-COMMUNISTS
																																																																													In August
																																																																													1960, President Eisenhower complained at a press conference that "Laos is
																																																																													a very confused situation." Civil war had broken out between the
																																																																													neutralist forces of paratroop commander Kong Le and rightwing Gen. Phoumi
																																																																													Nosavan. The Communist Pathet Lao supported Kong Le, while the US military and
																																																																													CIA lined up behind Phoumi. As Adm. Harry D. Felt, Commander in Chief of the
																																																																													Pacific Fleet, explained: "Phoumi is no George Washington. However, he is
																																																																													anti-Communist, which is what counts most in the sad Laos
																																																																													situation." 
As Phoumi prepared to march on Vientiane from his base in Savannakhet, US assistance to the rightwing general increased sharply. Special Forces personnel conducted intensive training of Phoumi's troops, while Air America transport flew in supplies from Bangkok. Phoumi also obtained support from his close friend, Thai Prime Minister Marshal Sarit Thanarat, who sent teams from the elite Police Aerial Reinforcement Unit to work with Phoumi's soldiers.
Heavy fighting took place in December as General Phoumi drove Kong Le out of Vientiane. By the end of the year, Kong Le--now receiving support from a Soviet airlift--had retreated north to the Plaine des Jarres (PDJ), securing the vital airfield complex in that area.
The appearance of the Soviets alarmed American military authorities. Admiral Felt cabled the Joint Chiefs of Staff on 29 December: "With full realization of the seriousness of the decision to intervene, I believe strongly that we must intervene now or give up northern Laos." Chief of Naval Operations Adm. Arleigh Burke agreed. "If we lose Laos," he told the Joint Chiefs on 31 December, "we will probably lose Thailand and the rest of Southeast Asia. We will have demonstrated to the world that we cannot or will not stand when challenged." The effect, Burke warned, would soon be felt throughout Asia, Latin America, and Africa.
In preparation for possible US military intervention in Laos, the Joint Chiefs ordered the emergency mobilization of a task force at Subic Bay in the Philippines. On New Year's Day, the American warships left port and headed north. At the same time, President Eisenhower was looking for ways to stabilize the situation in Laos without having to introduce American troops into the conflict. He therefore viewed with favor a CIA proposal to arm and train Hmong tribesmen.
THE
																																																																													PARU PROGRAM
																																																																													The Hmong
																																																																													project was primarily the work of CIA paramilitary specialist James W. (Bill)
																																																																													Lair. A veteran of World War II, Lair had joined the CIA at the outbreak of the
																																																																													Korean war. Assigned to Thailand, he had worked as a civilian instructor with
																																																																													the Thai Police Department in a CIA-sponsored program to enhance the
																																																																													organization's ability to deal with threats from Communist insurgents. Attached
																																																																													to the Border Police, Lair soon encountered the problem of assisting remote
																																																																													border outposts. When police units in outlying areas of Thailand were attacked
																																																																													by Communist guerrillas, it often took a week to get reinforcements to the
																																																																													stations. Lair argued that it would be better to have a parachute-trained unit
																																																																													for such emergencies. Although the Thai Army was not happy about the appearance
																																																																													of a paramilitary police organization, Thailand's government approved its
																																																																													creation. Aware of the Army's sensitivity, Lair selected an innocuous name for
																																																																													the new organization: Police Aerial Reinforcement Unit (PARU). 
Lair was proud of his role in developing the PARU program. He selected a training camp in south Thailand and initiated a rigorous program to create an elite paramilitary force. At one point, the PARU program was in danger of losing CIA support. It was saved through the intervention of Desmond FitzGerald, chief of the Far East Division in the Clandestine Service. By 1960, the PARU force numbered more than 400 highly trained individuals
 ENTER VANG PAO
																																																																													The key
																																																																													to the Hmong program was Vang Pao, a Hmong military leader who commanded the
																																																																													FAR's 10th Infantry Battalion on the PDJ. A talented and ambitious officer,
																																																																													Vang Pao had earlier come to the attention of Americans in Laos. In April 1957,
																																																																													the PEO had selected him to attend a six-month counterinsurgency training
																																																																													program at the Scout Ranger Base in Manila.
When fighting broke out in Laos at the end of 1959, Vang Pao had grown concerned that the Hmong were likely to suffer reprisals from the Communists because of the Hmongs' previous close association with the French. Encouraged by General Phoumi and assisted by a US Special Forces team, he began to organize a Hmong staybehind force on the southeastern edge of the PDJ. If the Communists occupied the Plaine, Vang Pao intended to relocate the Hmong to seven strategic mountaintops surrounding the PDJ and carry on the fight.
Aware that Vang Pao was seeking General Phoumi's assistance, Lair decided to look into the possibility of an expanded program with the Hmong commander. In late December 1959, Lair met with Vang Pao. VP, as he was known to the Americans, said that he either had to fight the Communists or leave the country; if the United States supplied the weapons, Vang Pao said that he would fight and that he could easily raise an army of 10,000.
Impressed with the Hmong commander, Lair returned to Vientiane and reported the contact to station chief Gordon L. Jorgensen. As it happened, Desmond FitzGerald was passing through Vientiane en route to Vietnam. Jorgensen suggested that he and Lair get together with FitzGerald for dinner. FitzGerald told Lair that the PARU's assistance to General Phoumi during his campaign against Kong Le had been worth everything that the CIA had spent on the program. Lair then outlined a program to support the Hmong. FitzGerald asked him to write up the proposal and send it to Washington.
Although Lair "never thought they would do it," he quickly dispatched an 18-page cable. A positive answer, he recalled, came back "surprisingly soon." Lair's proposal also gained the support of Admiral Felt and the State Department. President Eisenhower, looking for ways to avoid direct American involvement in Laos, was willing to go along with the CIA’s scheme.
																																																																													THE RAVENS
																																																																													The
																																																																													Ravens were American forward air-controllers who directed strikes from vulnerable,
																																																																													low-flying spotter planes, mainly in support of a Meo general named Vang Pao in
																																																																													Laos. "Advised" by the CIA, this fierce warlord fought to keep the
																																																																													North Vietnamese out of the strategic Plain of Jars. Robbins (Air America)
																																																																													conveys the unique flavor of Raven-style combat and also explains how the
																																																																													diplomatic-military dynamics of the clandestine war in Laos fit into the
																																																																													overall American effort in Southeast Asia. 
The cast of characters is memorable: a swaggering, rowdy bunch of mavericks whom their parent service (the US Air Force) had great difficulty controlling, they seemed to get by on sheer cussedness. The Ravens suffered the highest casualty rate of the Indochinese War. After the war, as refugees the displaced Meo/Hmong tribespeople settled uneasily in the United States including General Pao and their ongoing struggle to “ Propitiate the alien spirits of America.” The Hmong are very spiritual people and lifestyle in the US presented problems. Note: Propitiate: Win or regain the favor of (a god, spirit, or person) by doing something that pleases them.
In 1961-75 the CIA using Hmong tribesmen and Ravens, USAF forward air controllers (FACs), flew low and slow over the battlefields, calling in air strikes on North Vietnamese soldiers. These men exposed themselves to every sort of risk. As we have learned many are critical of US military strategy and command, generally dismissive of extravagant claims against the CIA, and partial to the FACs.
 BACKING THE RESISTANCE
																																																																													With
																																																																													authorization to arm and train 1,000 Hmong as a test of the concept, Lair again
																																																																													visited Vang Pao and arranged for an arms drop at Pa Dong, a mountaintop base
																																																																													south of the PDJ. In January 1961, Air America delivered weapons to the first
																																																																													300 trainees. The program nearly got off to a disastrous start when an Air
																																																																													America helicopter, carrying Lair and the PARU training team, crashed after
																																																																													failing to clear a ridge line when approaching the Hmong camp. Fortunately,
																																																																													there were no injuries. 

The PARU team conducted a three-day training program for the Hmong, involving the use of their weapons and basic ambush techniques. Lair also asked Vang Pao to select 20 men out of the 300 for training as radio operators. These individuals were sent to the PARU training camp in south Thailand for instruction.
With the Hmong scattered on mountainous terrain surrounding the PDJ, Lair recognized from the beginning that good communications would be crucial for effective operations, and he turned to Air America. In the early months of 1961, Air America had only a handful of helicopters and STOL aircraft available to support CIA operations in Laos. This changed in early March, when the new administration of President Kennedy became alarmed after Kong Le and the Pathet Lao captured a key road junction and threatened Vientiane and the royal capital at Luang Prabang. Kennedy again placed US military forces in the region on alert, and he also authorized the transfer of 14 UH-34 helicopters from the Marine Corps to Air America to be flown by Marine, Army, and Navy "volunteers."
On 29 March 1961, pilot Clarence J. Abadie led a flight of 16
																																																																													UH-34s from Bangkok to Air America's new forward operating base at Udorn in
																																																																													northeastern Thailand, 40 miles south of Vientiane. The helicopter forces soon
																																																																													became involved in supporting Hmong forces engaged in a fierce battle with the
																																																																													Pathet Lao at Pa Dong. On 30 May, the first Air America helicopter pilots died
																																																																													in Laos, when Charles Mateer and Walter Wizbowski crashed in bad weather while
																																																																													trying to land supplies to the besieged Hmong. 
Driven from Pa Dong, Vang Pao moved his headquarters to Pha Khao, 10 miles to the southwest. In July, Brig. Gen. Edward G. Lansdale--at that time a US security adviser--reported to Gen. Maxwell D. Taylor, President Kennedy's military adviser, that 13 PARU teams (99 men) were working with the Hmong, assisted by nine US Special Forces personnel. Nine CIA case officers were assigned to the Hmong program, with two backups in Vientiane. More than 9,000 Hmong had been equipped for guerrilla operations, with the possibility of securing 4,000 additional recruits.
As the Hmong force grew, so did Air America's presence in Laos.
																																																																													To connect the scattered Hmong outposts that were separated by mountainous
																																																																													terrain, Lair ordered the construction of a chain of airstrips, labeled Victor
																																																																													Sites (later called Lima Sites), that could be used by Air America's STOL
																																																																													airplanes. In April 1961, William R. Andersevic arrived in Vientiane to take
																																																																													charge of Air America's Helio program. Under his direction, the number of STOL
																																																																													sites expanded rapidly. Andersevic would locate suitable areas, then arrange
																																																																													for local people to cut down trees and level the ground as best they could with
																																																																													their primitive equipment. By the summer of 1961, Andersevic had given Lair a
																																																																													firm foundation upon which to build what would become an extensive network of
																																																																													STOL fields throughout northern Laos. 
Air America transports were also the key to feeding the people in the Hmong villages where the men had gone off to fight. Lair had enlisted the assistance of Edgar M. ("Pop") Buell to deal with this program. An Indiana farmer who had arrived in Laos in June 1960 to work with the International volunteer Service, Buell proved an inspired choice for the task. After a two-month trek around the perimeter of the PDJ, Buell arranged through Lair for Air America to make scheduled airdrops of rice to the Hmong villages.
 THE DIPLOMATIC TRACK
																																																																													While the
																																																																													Hmong program was expanding, President Kennedy had been seeking a diplomatic
																																																																													solution to the situation in Laos. At a meeting in Vienna in June 1961, Kennedy
																																																																													and Soviet Premier Nikita Khrushchev issued a joint statement of support for
																																																																													"a neutral and independent Laos." At the same time, negotiators met
																																																																													in Geneva to try to work out a settlement to the problem.
On 23 July 1962, a formal "Declaration on the Neutrality of Laos" was signed in Geneva. It provided for a coalition government and the withdrawal of all foreign troops from the country by 7 October. The United States pulled out its 666 military advisers and support staff, and Air America stopped dropping weapons to the Hmong. Assistant Secretary of State Averill Harriman, who was intent on ensuring US compliance with the Geneva accords, allowed the CIA to retain only two men in Laos to monitor Communist compliance with the agreement.
Air America's operations declined sharply in 1963. Restricted to
																																																																													food resupply to the Hmong, which averaged 40 tons a month by summer, the
																																																																													airline laid off people and mothballed airplanes. By May 1963, the number of
																																																																													UH-34s assigned to Udorn had dropped from 18 to six. Flight hours, which had
																																																																													averaged 2,000 per month before the Geneva accords, dropped to 600. As
																																																																													helicopter pilot Harry Casterlin wrote to his parents: "There are 37 of us
																																																																													over here and not enough work.... We are doing virtually no flying in Laos
																																																																													anymore.” 
																																																																													 
A
																																																																													BROKEN AGREEMENT
																																																																													Reports
																																																																													reaching CIA Headquarters from its two officers in Laos suggested that the
																																																																													apparent quiet was deceptive. It soon became clear that 7,000 North Vietnamese
																																																																													Army (NVA) troops had not left the country. In fact, the NVA was expanding its
																																																																													areas of control, attacking both neutralist and Hmong positions throughout
																																																																													Laos. As Hmong ammunition stores dwindled, William Colby, who was head of the
																																																																													CIA's Far East Division, pleaded to Harriman to allow the resumption of air
																																																																													shipments. "My arguments became more forceful," Colby recalled,
																																																																													"reflecting the intense cables I was receiving from the two CIA officers
																																																																													who were still up in the hills observing and reporting on what was
																																																																													happening." Harriman reluctantly approved an Air America arms drop--along
																																																																													with instructions that it be used for purely defense purposes. Further
																																																																													shipments followed. As Colby pointed out, however, Harriman personally
																																																																													approved “each and every clandestine supply flight and its
																																																																													cargo." 
 CONFLICT INTENSIFIES
																																																																													As Hanoi
																																																																													sent additional troops into Laos during 1963, the Kennedy administration
																																																																													authorized the CIA to increase the size of the Hmong army, now headquartered in
																																																																													the valley of Long Tieng. By the end of the year, a reported 20,000 Hmong were
																																																																													armed. They acted as guerrillas, blowing up NVA supply depots, ambushing
																																																																													trucks, mining roads, and generally harassing the stronger enemy force. Air
																																																																													America again took a greater role in the slowly expanding conflict. "The
																																																																													war is going great guns now," helicopter pilot Casterlin informed his parents
																																																																													in November 1963. "Don't be misled [by new reports] that I am only
																																																																													carrying rice on my missions as wars aren't won by rice." 
Full-scale fighting broke out in Laos in March 1964, when North
																																																																													Vietnamese and Pathet Lao forces attacked across the PDJ. By mid-May, the Communists
																																																																													had taken control of the strategic region, bringing an end to the already shaky
																																																																													coalition government. 
SEARCH
																																																																													AND RESCUE 
																																																																													While
																																																																													contemplating direct American military intervention, President Johnson ordered
																																																																													Navy and Air Force reconnaissance flights over the PDJ to provide intelligence
																																																																													and to send Hanoi "a message of American resolve." On 6 June, a naval
																																																																													reconnaissance aircraft was shot down over the PDJ. As the military services
																																																																													lacked a search-and-rescue capability in Laos, Air America undertook the
																																																																													responsibility. 
This unsuccessful attempt to rescue Lt. Charles E. Klusmann, who
																																																																													later escaped from his captors marked the beginning of what was perhaps the
																																																																													most demanding and hazardous of Air America’s operations in Laos. The airline's
																																																																													pilots were neither trained nor properly equipped for the dangerous
																																																																													search-and-rescue task, but there was no one else to do the job. This mission
																																																																													became even more difficult during the first half of 1965, when the air war
																																																																													expanded into the northwestern portion of North Vietnam.
As Air America crews in helicopters, transports, and T-28s risked their lives to save downed US airmen, rumors grew that the civilian pilots were receiving a bounty of $1,500 for each rescue. This story apparently originated with a US Air Force captain in the air attache’s office in Vientiane.
Charged with briefing military pilots on rescue capabilities in Laos, he visited Air Force bases and US Navy carriers, spreading the word that airmen who were shot down over Laos did not have to worry about being picked up: Air America's pilots would be there to get them out, competing for the $1,500 bonus.
When the story reached Air America, it created a good deal of resentment. In June 1965, after an especially hazardous long-range mission into North Vietnam in which two helicopters were badly shot up and a local Lao commander killed in what turned out to be a successful rescue of two Air Force officers from a downed F-4C, one of the Air America helicopter pilots wrote: "The AF doesn't, I'm sure, appreciate what we are doing for them at great risk to ourselves... . What makes us mad is that the AF thinks we get $1,500 for a pickup. We get nothing--but ulcers.”

In addition, WWII A-1 prop fighters were there to fly combat air
																																																																													patrol, or defensive patrols, to protect the Jolly Greens when they went in.
																																																																													The A-1 Skyraider arrived at Bien Hoa AB, RVN in May 1964 and proved to be a
																																																																													most capable war fighter in this environment. Initially, escorting rescue helicopters,
																																																																													known as RESCORT missions, was a secondary mission for the A-1s. The
																																																																													requirement was for four A-1s for each H-3, a requirement very difficult to
																																																																													meet. Finally, in August 1965, the 602nd Air Commando Squadron of A-1s moved
																																																																													from Bien Hoa to Udorn RTAFB. For the first time, eight A-1s were scheduled
																																																																													each day for RESCORT. For the most part, they used the call sign “Sandy,” a
																																																																													nickname that would hold. It was the nickname for the 602nd operations
																																																																													officer’s dog at home.
NOT
																																																																													VERY SECRET
																																																																													The year
																																																																													1965 marked the beginning of major military activity in what became known as
																																																																													the secret war in Laos. Although the full extent of the conflict was not
																																																																													revealed to the American people until 1969-70, the war was not all that secret.
																																																																													News of the fighting frequently found its way into the pages of The
																																																																													Bangkok Post, The New York Times, and other newspapers.
																																																																													Congress was kept well informed. As former CIA Director Richard Helms has
																																																																													pointed out, the Appropriations subcommittees that provided the funds for the
																																																																													war were briefed regularly. Also, Senator Stuart Symington and other
																																																																													Congressmen visited Laos and gave every indication of approving what was
																																																																													happening. They believed, Helms noted, that "It was a much cheaper and
																																																																													better way to fight a war in Southeast Asia than to commit American
																																																																													troops." 
The CIA was largely responsible for conducting military operations in Laos, but the US Ambassador was the man in charge. The secret war in Laos, author Charles Stevenson has emphasized, "was William Sullivan's war." Ambassador from December 1964 to March 1969, Sullivan insisted on an efficient, closely controlled country team. "There wasn't a bag of rice dropped in Laos that he didn't know about," observed Assistant Secretary of State William Bundy. Sullivan imposed two conditions upon his subordinates. First, the thin fiction of the Geneva accords had to be maintained to avoid possible embarrassment to the Lao and Soviet Governments; military operations, therefore, had to be carried out in relative secrecy. Second, no regular US ground troops were to become involved. In general, Ambassador Sullivan and his successor, G. McMurtrie Godley, successfully carried out this policy.
 
														ACTIVITY
																																																																													AT UDORN 
																																																																													The
																																																																													Ambassador in Vientiane delegated responsibility for the tactical conduct of
																																																																													the war to his CIA station chief. The primary headquarters for supervising the
																																																																													war, however, was in Udorn, Thailand. Located adjacent to the Air America
																																																																													parking ramp at Udorn Royal Thai Air Force Base, the 4802nd Joint Liaison
																																																																													Detachment was the CIA's command center for military operations in Laos. Lair
																																																																													was in charge of the 4802nd until the summer of 1968, when he was replaced by
																																																																													his longtime deputy, Lloyd ("Pat") Landry.
Both Lair and Landry had excellent rapport with Gen. Vitoon Yasawatdi, commander of "Headquarters 333" at Udorn, the Thai organization in charge of that country's forces in Laos. The Thai general, who had direct, private access to both the Lao and Thai prime ministers, had been identified by one senior CIA officer as "the single most important player in the Laos program."
 WEATHER AND THE WAR
																																																																													The early
																																																																													years of the war took on a seasonal aspect. During the dry period, which lasted
																																																																													from October to May, the North Vietnamese and Pathet Lao went on the offensive,
																																																																													applying pressure on the Hmong in northern Laos and on government forces
																																																																													throughout the country. During the monsoon, lasting from June to September, the
																																																																													anti-Communists took advantage of the mobility provided by Air America and
																																																																													struck deep into enemy-occupied territory. The situation was a mirror image of
																																																																													Vietnam. In Laos, the Communists acted as a conventional military force and
																																																																													were tied to fixed supply lines. The Hmong, at least at first, countered with
																																																																													guerrilla tactics.
The limited nature of the war was reflected in the modest losses--that is, modest in comparison to what was ahead--suffered by Air America during 1965, 1966, and 1967. Despite a rapid growth in personnel, Air America lost only 11 crew members in Laos during these three years, five of which were due to enemy action.
 NORTH VIETNAMESE PRESSURE
																																																																													The
																																																																													character of the war began to change in 1968. The North Vietnamese, impatient
																																																																													with the progress of the Pathet Lao, introduced major new combat forces into
																																																																													Laos and took control of the year's dry season offensive. By mid-March, they
																																																																													had captured a strategic valley north of Luang Prabang, successfully assaulted
																																																																													a key navigational facility that was used by the US Air Force for bombing North
																																																																													Vietnam, and threatened to push the Hmong out of their mountaintop strongholds
																																																																													surrounding the PDJ.
On 21 March 1968, CIA Headquarters issued a Special National Intelligence Estimate (SNIE) to top-level policymakers in Washington on Communist Intentions in Laos. Despite the presence of 35,000 NVA troops in the country, CIA analysts concluded that Hanoi was mainly interested in protecting its supply routes to South Vietnam and did not wish to destroy the general framework of the 1962 Geneva settlement.
Events soon proved the SNIE to be correct. The NVA offensive ended with the onset of the monsoon in May. The Hmong, however, had suffered heavy casualties, losing more than 1,000 men since January, including many top commanders. A recruitment drive turned up only 300 replacements: 30 percent were between the ages of 10 and 14, 30 percent were 15 and 16, while the remaining 40 percent were all over 35. According to "Pop" Buell, those between those ages were all dead.
 OFFENSIVE AND COUNTEROFFENSIVE
																																																																													As the
																																																																													strength of the Hmong waned, the United States tried to redress the growing
																																																																													imbalance of forces in the field through increased use of airpower. Between
																																																																													1965 and 1968, the rate of sorties in Laos had remained fairly constant at 10
																																																																													to 20 a day. In 1969, the rate reached 300 per day. 
During the rainy season of 1969, Vang Pao abandoned the use of guerrilla tactics and launched a major offensive against the NVA/Pathet Lao forces, using the increased airpower to support a drive against enemy positions on the PDJ. Operation About Face was a huge success. The Hmong reclaimed the entire PDJ for the first time since 1960, capturing 1,700 tons of food, 2,500 tons of ammunition, 640 heavy weapons, and 25 Soviet PT-76 tanks.
But the victory was short-lived. In January 1970, the NVA brought in two divisions that quickly regained all the lost ground and threatened the major Hmong base at Long Tieng. For the first time, B-52s were used to blunt the enemy drive.
NVA strength in Laos had reached 67,000 men, but CIA analysts continued to argue that the enemy did not want to risk a decisive action. “ he Communists believe that when they obtain their objectives in South Vietnam," the CIA's Office of National Estimates predicted in April 1970, "Laos will fall into their hands."
																																																																													LOSING GROUND
																																																																													The
																																																																													monsoon season of 1971 saw the last major offensive operations by the Hmong,
																																																																													now assisted by growing numbers of Thai volunteer battalions, trained and paid
																																																																													by the CIA. Vang Pao again captured the PDJ in July and established a network
																																																																													of artillery strongpoints, manned by Thai gunners. Vang Pao's hope of retaining
																																																																													the PDJ during the dry season went unfulfilled. In December 1971, the North
																																																																													Vietnamese launched a coordinated assault against the artillery bases. Using
																																																																													tanks and 130-mm guns that outranged the Thai artillery, the NVA quickly
																																																																													recaptured the PDJ.
The last days of 1971 and early months of 1972 saw increased enemy pressure on the main Hmong base at Long Tieng. Air America suffered heavy losses during this period. In December alone, 24 aircraft were hit by ground fire and three were shot down. Between December and April, six Air America crew members died in Laos.
The war also went badly in southern Laos, where the CIA recruited, trained, advised, and paid indigenous personnel who were organized into Special Guerrilla Units. Heavy fighting erupted in 1971 for control of the strategic Bolovens Plateau, with Air America providing the essential air transport for the CIA-led forces. By the end of the year, however, the NVA clearly held the upper hand following the capture of Paksong, 25 miles east of the Mekong River town of Pakse, on 28 December.
On 24 April 1972, Air America's vice president for flight operations sent a telex message addressed to all crew members. Noting that "the past few months have produced an appalling toll in lives and serious injuries," he urged all flight crews and supervisors to reappraise the factors "which make flying in our operations a particularly unforgiving profession. We are called upon to perform under possibly the most difficult environmental conditions in the world considering the combination of remote, mountainous terrain, absence of modern navigational/communications and air traffic control facilities, active presence of hostile armed forces, absence of adequate means of reporting and forecasting the varied seasonal weather and winds, and marginal airfields and landing zones, to name a few examples." Everyone, he warned, should exercise extreme caution when conducting flight operations in Laos.
 CLOSING DOWN
																																																																													At the
																																																																													same time that Air America crews were being reminded about the hazardous nature
																																																																													of operations in Laos, DCI Helms was deciding the fate of the air proprietary.
																																																																													On 21 April 1972, he ended a lengthy debate within the CIA over the continued
																																																																													need for a covert airlift capability, and ordered the Agency to divest itself
																																																																													of ownership and control of Air America and related companies. Air America
																																																																													would be retained only until the end of the war in Southeast Asia. 
On 27 January 1973, the Paris agreement on Vietnam was concluded, providing for the withdrawal of American troops. The following month, a cease-fire agreement was signed in Vientiane, leading to the formation of a coalition government for Laos. Although the end of the war was clearly in sight, Air America continued to lose people. Indeed, it is somewhat ironic that Air America suffered its heaviest losses in the two years following the CIA's decision to terminate the company. Between April 1972, when Helms issued his orders, and June 1974, when Air America left the country, 23 crew members died in flight operations in Laos.
On 3 June 1974, the last Air America aircraft crossed the border from Laos into Thailand. The end went well, Air America's operations office in Vientiane informed Washington ". . . .and the departure of AAM from Laos was without incident, although some lumps are visible in the throats of those who put so much of themselves into the operation over the years. . . .We grieve for those missing and dead in Laos and regret that they too could not have enjoyed today." In all, 100 Air America personnel had died in Laos.
The base at Udorn was shut down at the end of June. Operations in Vietnam continued until the fall of Saigon in April 1975. When plans for a new stay-behind company in Thailand, staffed by a contingent of select helicopter and transport pilots, fell through, all Air America personnel were discharged. The company finally closed its doors on 30 June 1976, returning more than $20 million to the US Treasury.
 A DISTINGUISHED RECORD
																																																																													CAT/Air
																																																																													America performed superbly for the CIA. The skilled aircrews and ground
																																																																													personnel of the air proprietary had given CIA the air transport capability
																																																																													required for a variety of covert operations in Asia. Although this "air
																																																																													complex"  had caused legal problems for the CIA's Directorate of
																																																																													Administration, there is no question that personnel in the Directorate of
																																																																													Operations considered CAT/Air America as an essential tool for their work.
During the war in Laos, Air America was called upon to perform paramilitary tasks at great risk to the aircrews involved. Although lacking the discipline found in a military organization, the personnel of the air proprietary continued to place their lives at hazard for years. Some Air America pilots flew in Laos for more than a decade, braving enemy fire and surmounting challenging operational conditions with rare skill and determination. As pointed out by a senior Agency official during the dedication of a plaque to Air America personnel at CIA Headquarters in May 1988: "The aircrew, maintenance, and other professional aviation skills they applied on our behalf were extraordinary. But, above all, they brought a dedication to our mission and the highest standards of personal courage in the conduct of that mission."
The exploits of CAT/Air America form a unique chapter in the history of air transport, one that deserves better than a misleading, mediocre movie. There are other things about this war, that need to be told.
C-123 Airplanes, Jungle, People and Agent Orange Residue
During the Vietnam War, the United States military used a herbicide called Agent Orange as a defoliant in Vietnam and on the perimeters of certain Royal Thai Air Force Bases in Thailand. Agent Orange was sprayed by C-123 aircraft as a part of a means of killing vegetation in Vietnam during the war, aiming at the roads and trail bringing Chinese and Russian supplies to the South.
 
														C-123 aircraft were used to spray Agent Orange over forested areas in Vietnam primarily finding and defoliate segments of the Ho Chi Minh Trail. IT WAS CALLED OPERATION RANCH HAND. The C-123 aircraft were fitted with spray tanks to spray the herbicide across large areas of the country. there were variations
Following a report released by the Institute of Medicine called Post-Vietnam Dioxin Exposure in Agent Orange-Contaminated C-123 Aircraft, the VA has conceded that Airmen who worked on C-123 aircraft as apart of Operation Ranch Hand were exposed to Agent Orange, and qualify for presumptive service connection for certain diseases associated with Agent Orange exposure.
 
														LOW SLOW AND DANGEROUS
IT DAMAGED MORE THAN PLANTS  -  IT DAMAGED PEOPLE THEN and NOW
The report found that the C-123 aircraft used during Operation Ranch Hand had residue of Agent Orange, and those who worked on these aircrafts after their return were exposed to the herbicide. After Operation Ranch Hand, C-123 aircraft were returned to the United States to be used by the Air Force and Air Force reserves, exposing service members to the Agent Orange that remained on the aircraft. The report found that exposure to Agent Orange could result in adverse health issues.

As a result of the report, the VA has added those who worked on or served onboard these aircraft to the VA’s herbicide presumption regulation. Vietnam veteran Robert P. Patenaude with the Agent Orange spray plane he and others crewed during the war.
The C 123 transport named “Patches" because of all the bullet holes it received is now in a container that can only be accessed with hazmat suits, according to Patenaude, who receives disability payments because of Agent Orange.
When those planes returned they were made into ambulances, transports and now, three decades later, veterans of the 439th Tactical Airlift Wing at Westover Air Reserve Base believe those airplanes are responsible for making them sick. For nine years they flew in them, they fixed them and they treated patients in them. Unknown to the veterans, the C-123 Providers, which had previously flown in Vietnam, were contaminated with Agent Orange.
Many in an effort to hide evidence or simply neutralize the C-123’s was called forth to the Bone Yard.

WASHINGTON –
Nearly three dozen rugged C-123 transport planes formed the backbone of the U.S. military’s campaign to spray Agent Orange over jungles hiding enemy soldiers during the Vietnam War. And many of the troops who served in the conflict have been compensated for diseases associated with their exposure to the toxic defoliant.
But after the war, some of the planes were used on cargo missions in the United States. Now a bitter fight has sprung up over whether those in the military who worked, ate and slept in the planes after the war should also be compensated. Two U.S. senators are now questioning the Department of Veterans Affairs’ assertions that any postwar contamination on the planes was not high enough to be linked to disease.
Complicating the debate is that few of the planes remain to be tested. In 2010, the air force destroyed 18 of the Vietnam-era aircraft in part because of concerns about potential liability for Agent Orange, according to air force memos documenting the destruction.   The air force says the planes’ destruction was handled properly.
The air force aborted plans to sell some of the planes in 1996, after evidence surfaced that 18 of them might still be contaminated with TCDD dioxin, a carcinogen associated with Agent Orange, according to air force documents and papers filed with the General Services Administration’s Board of Contract Appeals. The planes were quarantined instead in Arizona at a storage facility at Davis-Monthan Air Force Base, nicknamed “the Boneyard.”
The air force did not notify the post-Vietnam crews or Boneyard employees of the potential risk, according to air force documents.
THE WAR EFFORT
During the Vietnam War, the U.S. Air Force used C-123 aircraft to spray Agent Orange to clear jungles that provided enemy cover in Vietnam. At the end of the spraying campaign in 1971, the remaining C-123 planes were reassigned to reserve units in the US for routine cargo and medical evacuation missions spanning the next 10 years.  After the front line or behind line action involving the Ho Chi Minh Trail Defoliation, there were questions as to how well these aircraft were “neutralized”. 

Some Air Force Reservists who were crew members on C-123 Provider aircraft, formerly used to spray Agent Orange during the Vietnam War, have raised health concerns about exposure to residual amounts of herbicides on plane surfaces.
Responding to these concerns, VA asked the Health and Medicine Division (HMD) (formally known as the Institute of Medicine) of the National Academy of Sciences, Engineering, and Medicine to study possible exposure and increase in adverse health effects in C-123 crew members.
HMD released its report, Post-Vietnam Dioxin Exposure in Agent Orange-Contaminated C-123 Aircraft, Jan. 9, 2015. According to the report, from 1972 to 1982, approximately 1,500 to 2,100 Air Force Reserve personnel trained and worked on C-123 aircraft that previously had been used to spray herbicides, including Agent Orange, in Vietnam.
HMD found that Reservists who served as flight crew (pilot, navigator, flight engineer, and loadmaster), ground maintenance crew, and aero-medical personnel had regular contact with the aircraft, and would have experienced some exposure to chemicals from herbicide residue. The report determined that it is possible that this exposure contributed to some adverse health effects.
TCDD, the toxic substance in Agent Orange, may be inhaled as an aerosol or ingested by contaminated food or water or from hand-to-mouth transfer or “BETTER DEATH THROUGH DUPONT”
In response to the Institute of Medicine’s report on Post-Vietnam Dioxin Exposure in Agent Orange-Contaminated C-123 Aircraft from the National Academy of Sciences, we have determined there is evidence of exposure to Agent Orange for Airmen who worked on C-123s that were used in Vietnam as part of Operation Ranch Hand.
Specifically, we have determined there is sufficient evidence that Air Force and Air Force Reserve members who served during the period 1969 through 1986 and regularly and repeatedly operated, maintained, or served onboard C-123 aircraft (known to have been used to spray an herbicide agent during the Vietnam era) were exposed to Agent Orange.
