The desperate evacuation of Saigon
- Chopper pilots tell stories about last days of Vietnam War
- “Operation Frequent Wind” was history’s largest helicopter evacuation
- On 40th anniversary, witnesses tell how 7,000 fled Saigon via chopper in under 24 hours
Its pilot knew there was no room for error. Scores of South Vietnamese were lined up on that rooftop, waiting anxiously to scramble aboard his chopper. They knew 150,000 North Vietnamese troops were just outside the city, ready to pounce.
Delicately working the controls, the pilot reduced power just enough to set down but leaving enough lift in the spinning rotor to keep much of the aircraft’s weight off the rickety roof.
He held steady, while desperate men, women and children, some carrying luggage, hoisted themselves inside the vibrating aircraft. The pilot made sure they stayed clear of the deadly rotor blades while he avoided rooftop antennas that could trigger a crash.
After 15 passengers squeezed into a compartment meant for nine, it was time to go. Very slowly, the pilot raised the aircraft and pointed the helicopter forward. About 40 minutes later, the evacuees landed safely aboard a U.S. Navy ship offshore.
Now, imagine doing that again. And again. And again. All day long. No sleep, little food. Overbearing tension.
This week marks exactly 40 years since the largest helicopter airlift in history, Operation Frequent Wind.
By the time it was over, about 100 Marine, Air Force and Air America choppers had evacuated an estimated 7,000 Americans and South Vietnamese out of Saigon in under 24 hours.
The airlift was prompted by some harsh realities. U.S. combat forces had been out of the war for two years after a ceasefire agreement with the North. U.S. President Richard Nixon had promised to respond with “full force” if the North violated the ceasefire. But now Nixon was powerless — forced out of office and disgraced by the Watergate scandal. Bottom line: South Vietnam was about to lose the war.
A city gripped by fear
U.S. authorities faced excruciatingly difficult questions: When to leave? Who should be allowed to go? How to evacuate?
No one knew how it would all play out. And the entire world was watching.
Chaos ruled the city. There were fears about massive arrests, “re-education” camps and executions at the hands of the communists. Thousands of Americans and their Vietnamese family members wondered how — or even if — they were going to safely escape.
The airlift was triggered by a North Vietnamese attack on Saigon’s airport, which ruined runways and made a mass airplane evacuation impossible. The only option left, planners said, was to use helicopters, which were slower and smaller than planes. The chopper option was the least desirable and the most hazardous, pilots said.
It must have sounded very weird when American Forces Radio broadcast Bing Crosby’s “White Christmas” on the morning of April 29 and announced “the temperature is 105 degrees and rising.”
That was the signal. Americans and hand-picked Vietnamese began heading toward predetermined assembly spots.
Operation Frequent Wind was on.
“At the time, you realized it was historic,” retired Col. Gerry Berry told CNN.
Which rooftop? ‘We just picked one’
Berry was then a 30-year-old U.S. Marine Corps helicopter pilot whose orders were simple: get the American ambassador out of the U.S. Embassy. But as he learned later, nothing turned out to be simple that day.
Tony Coalson, 32, flew choppers for Air America, the CIA air service. Coalson was assigned the dangerous task of landing on unfamiliar rooftops throughout the city, picking up unknown evacuees and flying them to staging areas or U.S. Navy ships offshore.
“There were so many rooftops that we didn’t know, really, what rooftop was what,” Coalson told CNN. “We just picked one out, and we landed there.”
Air America pilot Robert Caron told CNN how his rooftop chopper rescue led to one of the most iconic photos of the era. And Chris Woods shared his experience as crew chief of the last U.S. chopper to leave the embassy, shutting the door on America’s involvement in Vietnam.
Air America choppers started the evacuation flights early that morning, with about 17 helicopters taking part, both military and civilian versions of the famous UH-1 “Huey.”
The original plan called for most flights to arrive and depart from the U.S. Defense Attache Office, near the airport. But as word of the evacuation spread, thousands of Vietnamese began heading to the embassy compound. Soon, planners realized more choppers had to be sent to the embassy.
Thick crowds jammed the gates, some holding papers claiming they had worked for the Americans. Others said they were dependents of American citizens. Many feared their U.S. connections would put them in danger under a North Vietnamese regime. Embassy Marine guards chose who to let inside.
“It actually just went beyond chaos,” Coalson said. “It was indescribable. And it was like a tsunami of people.”
Hailing from Oxford, Alabama, this was Coalson’s second time serving in South Vietnam. He’d flown Hueys in the Army in 1967 and ’68. He’d been flying with Air America since 1970.
On April 29, Coalson flew alone, without a co-pilot. Often when he would land on a rooftop, his chopper would be “mobbed by people. You had to watch your tail rotor so somebody didn’t walk into that.”
For a lone pilot, cutting off the stream of anxious evacuees when the chopper filled up was tricky. He couldn’t leave the cockpit. And the passengers wouldn’t stop trying to get aboard.
So, Coalson used his chopper to give them a hint that he was leaving.
“You just slowly start to lift up, very, very slowly,” Coalson said. “And people knew, ‘Well, if we can’t get in, we’re certainly not gonna be able to get on, because this aircraft, I think, is takin’ off’ — which it was.” Coalson flew more than 10 hours that day without rest.
Other pilots reported that some evacuees wouldn’t let go. As the choppers took off, they’d find themselves dangling from the landing skids until the pilot was able to shake them off.
At about 2:30 p.m., 41-year-old Caron unintentionally starred in one of the most famous photographs of the Vietnam War. It happened because CIA air officer Oren “O.B.” Harnage asked Caron and co-pilot Jack “Pogo” Hunter to pick up “the deputy prime minister and his family.”
United Press International’s Hugh van Es photographed Caron and Hunter’s chopper perched atop Saigon’s Pittman Building, about a half-mile from the embassy. In the picture, Harnage is seen standing on the roof, helping evacuees climb a ladder to get on board. The iconic photograph has come to symbolize the chaos and desperation of that day.
“I remember looking out there at the people coming up the ladder,” Caron told CNN. “And I turned to Pogo and said, ‘I tell you what, this prime minister has a pretty damned big family!’ It was 50 people. As you can imagine, as word spread, everyone they knew suddenly became ‘family.’ “
‘I’m here to get the ambassador’
The Marines didn’t start their chopper airlift until the afternoon. About 65 U.S. Marine and 10 Air Force choppers took part, Berry recalled. Some helicopters shuttled evacuees from the Defense Attache Office to the Navy fleet.
Other pilots, like Berry, were sent to the embassy.
Berry grew up in Montana and joined the Marines at 22. No rookie to the Sea Knight, he’d already flown them in combat — in 1969 and ’70. “I’d lost a lot of friends,” Berry said. As the end of the war drew near, he feared the sacrifices had been “all for naught.”
On April 29, at about 1 p.m., Berry’s Sea Knight — call sign Lady Ace 09 — landed behind the embassy on a special mission.
“I’m here to get the ambassador,” Berry told a Marine guard. But instead of escorting the ambassador aboard, Marine guards loaded Berry’s chopper with 65 to 80 Vietnamese and other non-U.S. evacuees. Not knowing what else to do, Berry flew his passengers offshore to the USS Blue Ridge, where Navy brass were expecting the arrival of the ambassador.
He didn’t know it at the time, but Berry was in for a very long day.
A powerful CH-53 Sea Stallion helicopter departs the USS Hancock to evacuate Saigon in April, 1975.
Lady Ace 09 was just one of a swarm of U.S. helicopters that shuttled back and forth between the fleet and Saigon that day, including powerful Marine CH-53 and HH-53 Air Force choppers, which were too heavy to land on the embassy rooftop helicopter pad.
Berry’s first evacuation trip led to another. Then another.
“The first couple times, I always said, ‘I’m here to get the ambassador.’ ” But the attitude of the Marine guards “was like, ‘Fine. Tell somebody who cares.’ ” With each touchdown on the embassy rooftop, Berry lowered the chopper’s rear loading ramp to allow evacuees to fill the aircraft.
Throughout the day, Berry watched the streets fill with residents as enemy tanks approached the city. Each time he returned to the embassy, Berry noticed more people had entered the compound. The evacuation flights didn’t seem to be reducing the crowds. And clearly they all expected to be airlifted out.
He began to wonder what was keeping the ambassador. Was he waiting for orders from Washington? Or was he waiting until all the evacuees had gone?
Berry said ground fire was his biggest concern. Each time Lady Ace 09 touched down on the embassy roof, it was a sitting target, surrounded by possibly armed South Vietnamese soldiers and civilians.
Again the ambassador didn’t show. Berry’s Sea Knight filled with more evacuees bound for the fleet.
For more than 10 hours straight, Air America pilot Tony Coalson plucked evacuees from building rooftops right before the fall of Saigon.
Coalson’s final flight to the embassy provided one of his most powerful memories.
“I landed on the rooftop,” Coalson recalled. “And I went down below. And they had a big office down there. And it was really surreal. … And you had the secretaries. Everybody was in kind of a jovial mood. … And that’s when — as you say — you execute your authority. And you pointed out just: “You, you, you, up on the deck. And we’re out.
“I’ll never forget that.”
Choppers pushed overboard
There were South Vietnamese pilots who engineered their own evacuations. Some of them commandeered helicopters and flew offshore to meet the American fleet. Some ditched their choppers near the Navy ships and swam the rest of the way. Many South Vietnamese choppers that were able to land on deck were pushed overboard because of a lack of space.
Saigon evacuees pass the time below deck on the Navy carrier USS Hancock in April 1975.
When a huge, South Vietnamese Chinook helicopter landed aboard the aircraft carrier USS Hancock, the American sailors and Marines tried to push it over the side. It wouldn’t budge.
Chris Woods — a 23-year-old Marine sergeant and helicopter crew chief — realized what the problem was.
“I kind of ‘got volunteered’ to go inside the aircraft and release the parking brake. I told everybody, ‘Don’t start pushing till I get out!’ I climbed in, and released it, but they didn’t wait on me, ’cause that thing was rolling backwards. Obviously I jumped out before it went overboard.”
Woods remembers the terrible noise the Chinook made when it scraped the Hancock’s rear end, and fell into the ocean with a huge splash.
When helicopters threatened to take too much space aboard the USS Hancock, many were tossed overboard.
Later that night, Woods was on deck when a Sea Knight with the call sign YT-14 crashed into the water while approaching the carrier.
“I remember seeing a big, bright flash, and the Hancock’s warning system going off, and the air boss saying, ‘Crash! Crash! Crash!’ My heart sank,” Woods said. “It was rough to take, knowing that our Marine brothers had crashed and were lost at sea.”
YT-14 was the final U.S. helicopter lost in Vietnam.
The pilots, Capt. William Nystul and Lt. Michael Shea, were among the last Americans to die in the conflict.
The magic words
It was 4:50 a.m. April 30 aboard Lady Ace 09. Pilots were normally restricted to about six consecutive hours in the cockpit a day. But Berry was into his 17th hour of shuttling back and forth between the fleet and the embassy rooftop helicopter pad without rest.
“It was exhausting,” he said. “I don’t think I felt physical fatigue like I felt mental fatigue. I think mentally, you just got so frustrated with this thing.”
Berry landed a 14th time at the U.S. Embassy. Another load of evacuees boarded the aircraft. And once again, the ambassador wasn’t among them.
That’s when Berry’s frustration hit the ceiling.
“I called the sergeant over. And he got up in the cockpit. And I said, ‘This is it. Get all these people off. This helicopter’s not leaving the roof until the ambassador’s on board.’ And then, as an afterthought, I said, ‘The President sends.’ “
That was kind of a bold move. To get the sergeant to pay attention, Berry was telling him in Marine-speak that he was “sending” a message from the commander in chief. Berry joked to CNN that “in this case, ‘the President sends,’ was a bit out of my bailiwick.”
Nonetheless, those magic words worked.
The sergeant removed all the evacuees from the chopper and went downstairs. Two minutes later, Martin and his entourage appeared on the roof and boarded the aircraft. “Graham Martin looked very tired, extremely haggard,” Berry recalled. “I’m sure the pressure was immense.”
With the ambassador secure aboard the chopper, Berry radioed the code words: “tiger, tiger, tiger” as he headed out to sea. “And we land on the USS Blue Ridge.”

After 18 hours, 18 minutes of nonstop flying in a war zone, Berry could finally stand down. Mission accomplished.
Years later, Berry learned that a 9-year-old Vietnamese boy he evacuated that day had grown up to be a U.S. Marine chopper pilot himself.
‘Another horrendous screwup’
In Washington, Secretary of State Henry Kissinger announced it was over. The last U.S. chopper had left the U.S. Embassy.
But that wasn’t quite accurate. In fact, 11 U.S. Marines had been left on the embassy roof.
Kissinger, in the 2014 documentary, “Last Days in Vietnam,” called it “another horrendous screwup.”
Also still on the compound were 420 non-U.S. citizens who, according to the film, were promised airlifts out but instead were left behind.
“We were told that Martin had left on the last helicopter and that the evacuation had ended,” Kissinger said.
The Marines barricaded themselves on the roof and prepared to defend themselves against a possible attack.
The last men out
After sunrise, the USS Hancock sent out a final chopper to rescue the stranded Marines. The mission went to Woods and fellow crewmen of a Sea Knight with the call sign Swift 22.
Approaching the embassy, Woods looked down from his position near the cockpit to see the compound was “overrun” by “hundreds or thousands” of South Vietnamese. “Like ants on a watermelon, they were just everywhere trying to get up to the rooftop so they could maybe catch a flight out of Saigon.”
The chopper set down on the Embassy’s rooftop helicopter pad and Woods opened the ramp and hatch.
There had been no attack. After surviving the night uninjured, all 11 Marines ran aboard.
Embassy guard Master Sgt. Juan Valdez trailed last.
But according to the 2011 book “Last Men Out,” by Bob Drury and Tom Clavin, Valdez almost didn’t make it.
Woods said a leaky tear gas grenade on board was threatening to fill the chopper with toxic fumes. “I threw it out the window,” he said. “We lifted up 10 feet,” but then set down again so one of the pilots could put on his gas mask.
With the loading ramp still lowered, the helicopter bounced as it left the roof, and then came back down, according to the book.
“Valdez rolled out of the chopper … Three sets of hands shot out” to grab Valdez. But Valdez “waved them off and got to his knees” and “clambered back aboard,” taking a seat in the aircraft, Clavin and Dury wrote.
Woods noticed none of that. He was standing 30 feet away in the front of the cargo hold, near the cockpit, looking for signs of enemy fire and helping the pilots stay clear of dangerous antenna and guy wires as they lifted off.
“I was busy …” Woods joked. He remembers a few high fives as the chopper lifted off.
One of the Marines marked the time on his watch: 7:58 a.m. April 30, 1975.
The world’s largest helicopter airlift was history. The Americans had left the building.
“We were gettin’ out of Dodge pretty quick,” Woods said. Swift 22 carried the embassy’s last Marine security guards to the safety of the awaiting Navy fleet.
Less than three hours later, North Vietnamese tanks smashed through the gates of the Presidential Palace. Saigon would be renamed Ho Chi Minh City.
After 20 years of involvement, and 58,220 U.S. military deaths, America was finally done with Vietnam.
