Isegoria

The D-21 drone used a ramjet, just like its Oxcart mothership, Annie Jacobsen explains (in Area 51), and needed to be launched at supersonic speed:

For public safety reasons, the plan was to launch the triplesonic drone off the coast of California in March of 1966 for the first test, and to prepare his pilots, Colonel Slater had them swim laps each day in the Area 51 pool, first in bathing suits and then with their pressure suits on. “We’d hoist the guys up over the water in a pulley and then drop them in the pool. As soon as they hit the water the first time, the pressure suit inflated, so we had to have that fixed,” Slater recalls. When it came time to practice an actual landing in a large body of water, the Agency’s highest-ranking officer on base, Werner Weiss, got the Coast Guard to seal off a large section of Lake Mead, the largest reservoir of water in the United States, located just east of Las Vegas.

[…]

Both aircraft flew west until they were a hundred and fifty miles off the coast of California. There, the M-21, piloted by Bill Park, prepared for the D-21 launch. A camera in Slater’s airplane would capture the launch on 16-millimeter film. Down below, on the dark ocean surface, a rescue boat waited. Park hit Ignite, and the drone launched up and off the M-21. But during separation, the drone pitched down instead of up and instantly split the mother aircraft in half. Miraculously, the drone hit neither Park nor Torick, who were both trapped inside.

The crippled aircraft began to tumble through the sky, falling for nearly ten thousand feet. Somehow, both men managed to eject. Alive and now outside the crashing, burning airplane, both men were safely tethered to their parachutes. Remarkably, neither of the men was hit by the burning debris falling through the air. Both men made successful water landings. But, as Slater recalls, an unforeseen tragedy occurred. “Our rescue boat located Bill Park, who was fine. But by the time the boat got to Ray Torick, he was tied up in his lanyard and had drowned.”

Kelly Johnson was devastated. “He impulsively and emotionally decided to cancel the entire program and give back the development funding to the Air Force and the Agency,” Johnson’s deputy Ben Rich recalled in his 1994 memoir about the Lockheed Skunk Works. Rich asked Johnson why. “I will not risk any more test pilots or Blackbirds. I don’t have either to spare,” Johnson said. But the Air Force did not let the Mach 3 drone program go away so quickly. They created a new program to launch the drone from underneath a B-52 bomber, which was part of Strategic Air Command. President Johnson’s deputy secretary of defense, Cyrus Vance, told Kelly Johnson, “We need this program to work because our government will never again allow a Francis Gary Powers situation develop. All our overflights over denied territory will either be with satellites or drones.”

Three years later, in 1969, the D-21 drone finally made its first reconnaissance mission, over China, launched off a B-52. The drone flew into China and over the Lop Nur nuclear facility but had then somehow strayed off course into Soviet Siberia, run out of fuel, and crashed. The suggestion was that the drone’s guidance system had failed on the way home, and it was never seen or heard from again. At least, not for more than twenty years. In the early 1990s, a CIA officer showed up in Ben Rich’s office at Skunk Works with a mysterious present for him. “Ben, do you recognize this?” the man asked Rich as he handed him a hunk of titanium. “Sure I do,” Rich said. What Ben Rich was holding in his hand was a piece of composite material loaded with the radar-absorbing coating that Lovick and his team had first developed for Lockheed four decades before. Asked where he got it, the CIA officer explained that it had been a gift to the CIA from a KGB agent in Moscow. The agent had gotten it from a shepherd in Siberia, who’d found it in the Siberian tundra while herding his sheep. According to Rich, “The Russians mistakenly believed that this generation-old panel signified our current stealth technology. It was, in a way, a very nice tribute to our work on Tagboard.”

Preparing for Oxcart missions involved punishing survival-training operations, Annie Jacobsen explains (in Area 51), but the high-desert survival training at Area 51 felt different — and would involve psychological warfare by mock enemy Chinese:

“I crawled slowly through the brambles, bugs, and mud for about thirty minutes when, suddenly, I hit a trip wire and alarms went off. A glaring spotlight came on and ten Chinese men in uniform grabbed me and dragged me to one of their jeeps.” Collins was handcuffed, driven for a while, put into a second vehicle, and taken to so-called Chinese interrogation headquarters. There, he was stripped naked and searched. “A doctor proceeded to examine every orifice the human body has, from top to bottom—literally,” which, Collins believes, “was more to humiliate and break down my moral defenses than anything else.” Naked, he was led down a dimly lit hallway and pushed into a concrete cell furnished with a short, thin bed made of wood planks. “I had no blanket, I was naked, and it was very cold. They gave me a bucket to be used only when I was told.”

For days, Collins went through simulated torture that included sleep deprivation, humiliation, extreme temperature fluctuation, and hunger, all the while naked, cold, and under surveillance by his captors. “The cell had one thick wooded door with a hole for viewing. This opening had a metal window that would clank open and shut. A single bright light was on and when I was about to doze off, the light would flash off, which would immediately snap me out of sleep.” For food, he was given watery soup, two thin pepper pods, and two bits of mysterious meat. “I had no water to drink and I was always watched. I didn’t know day from night so there was no sense of time. The temperature varied from hot to very cold. The voice through the viewing window shouted demands.”

Soon Collins began to hallucinate. Now it was interrogation time. Naked, he was led to a small room by two armed guards. He stood in front of his Chinese interrogators, who sat behind a small desk. They grilled him about his name, rank, and why he was spying on China. The torturous routine continued for what Collins guessed was several more days. Then one day, instead of being taken to his interrogators, he was told that he was free to go.

But halfway across the world, on November 1, 1963, Ken Collins’s experience was being mirrored for real. A CIA pilot named Yeh Changti had been flying a U-2 spy mission over a nuclear facility in China when he was shot down, captured by the Chinese Communist government, and tortured. Yeh Changti was a member of the Thirty-Fifth Black Cat U-2 Squadron, a group of Taiwanese Chinese Nationalist pilots (as opposed to the Communist Chinese, who inhabited the mainland) who worked covert espionage missions for the CIA. In the 1960s, the Black Cats flew what would prove to be the deadliest missions in the U-2’s fifty-five-year history, all of which were flown out of a secret base called Taoyuan on the island of Taiwan. When the CIA declassified most of the U-2 program, in 1998, “no information was released about Yeh Changti or the Black Cats,” says former Black Cat pilot Hsichun Hua. The program, in entirety, remains classified as of 2011.

Colonel Hugh “Slip” Slater, the man who would later become the commander of Area 51, remembers Yeh Changti before he got shot down. “His code name was Terry Lee and he and I played tennis on the base at Taoyuan all the time. He was a great guy and an amazing acrobat, which helped him on the court. Sometimes we drank scotch while we played. Both the sport and the scotch helped morale.” Slater says that the reason morale was low was that “the U-2 had become so vulnerable to the SA-2 missiles that nobody wanted to fly.” One Black Cat pilot had already been shot down. But that didn’t stop the dangerous missions from going forward for the CIA.

Unlike what had happened with the Gary Powers shoot-down, the American press remained in the dark about these missions. For the CIA, getting hard intelligence on China’s nuclear facilities was a top national security priority. On the day Yeh Changti was shot down, he was returning home from a nine-hour mission over the mainland when a surface-to-air missile guidance system locked on to his U-2. Colonel Slater was on the radio with Yeh Changti when it happened. “I was talking to him when I heard him say, ‘System 12 on!’ We never heard another word.” The missile hit Yeh Changti’s aircraft and tore off the right wing. Yeh Changti ejected from the airplane, his body riddled in fifty-nine places with missile fragments. He landed safely with his parachute and passed out. When he woke up, he was in a military facility run by Mao Tse-tung.

This was no training exercise. Yeh Changti was tortured and held prisoner for nineteen years until he was quietly released by his captors, in 1982. He has been living outside Houston, Texas, ever since. The CIA did not know that Yeh Changti had survived his bailout and apparently did not make any kind of effort to locate him. A second Black Cat pilot named Major Jack Chang would also get shot down in a U-2, in 1965, and was imprisoned alongside Yeh Changti. After their release, the two pilots shared their arduous stories with fellow Black Cat pilot, Hsichun Hua, who had become a general in the Taiwanese air force while the men were in captivity. Neither Yeh Changti nor Major Jack Chang was ever given a medal by the CIA. The shoot-down of the Black Cat U-2 pilots, however, had a major impact on what the CIA and the Air Force would do next at Area 51. Suddenly, the development of drones had become a national security priority, drones being pilotless aircraft that could be flown by remote control.

Drones could accomplish what the U-2 could in terms of bringing home photographic intelligence, but a drone could do it without getting pilots captured or killed. Ideally, drones could perform missions that fell into three distinct categories: dull, dirty, and dangerous. Dull meant long flights during which pilots faced fatigue flying to remote areas of the globe. Dirty included situations where nuclear weapons or biological weapons might be involved. Dangerous meant missions over denied territories such as the Soviet Union, North Korea, and China, where shoot-downs were a political risk. Lockheed secured a contract to develop such an unmanned vehicle in late 1962. After Yeh Changti’s shoot-down, the program got a big boost. Flight-testing of the drone code-named Tagboard would take place at Area 51 and, ironically, getting the Lockheed drone to fly properly was among the first duties assigned to Colonel Slater after he left Taoyuan and was given a new assignment at Area 51.

“Lockheed’s D-21 wasn’t just any old drone, it was the world’s first Mach 3 stealth drone,” says Lockheed physicist Ed Lovick, who worked on the program. “The idea of this drone was a radical one because it would fly at least as fast, if not faster, than the A-12. It had a ram jet engine, which meant it was powered by forced air. The drone could only be launched off an aircraft that was already moving faster than the speed of sound.” The A-12 mother ship was designated M-21, M as in mother, and was modified to include a second seat for the drone launch operator, a flight engineer. The D-21 was the name for the drone, the D standing for daughter. But launching one aircraft from the back of another aircraft at speeds of more than 2,300 mph had its own set of challenges, beginning with how not to have the two aircraft crash into each other during launch. The recovery process of the drone also needed to be fine-tuned. Lovick explains, “The drone, designed to overfly China, would travel on its own flight path taking reconnaissance photographs and then head back out to sea.” The idea was to have the drone drop its photo package, which included the camera, the film, and the radio sensors, by parachute so it could be retrieved by a second aircraft nearby. Once the pallet was secure, the drone would crash into the sea and sink to the ocean floor.

The Oxcart’s J-58 jet engines developed by Pratt and Whitney were finally delivered in 1963, Annie Jacobsen explains (in Area 51), but not without complications:

A host of new problems occurred when the engines were first powered up. In one instance, engineers suspected a foreign object was stuck in an engine’s heart, called the power plant, and was damaging internal parts. An X-ray showed the outline of a pen that had fallen into the engine’s cover, called a nacelle, during final assembly in Burbank. From then on, Lockheed workers got coveralls without breast pockets.

[…]

The engines worked like giant vacuums. Once powered up on the tarmac, they sucked in every loose object lying around, including rocks and metal screws. As a solution, Area 51 workers took to sweeping and then vacuuming the runway before each flight. It was a tedious but necessary job.

[…]

As the airplane reached higher speeds, the 500-plus-degree temperatures began melting electrical components, many of which had to be redesigned and rewired.

[…]

In the case of the Oxcart, the sonic shock unexpectedly caused the fuselage to flex in such a way that many structural parts became dangerously compromised. These parts had to be redesigned and replaced.

[…]

Every flight was like an operational mission, with navigators plotting a course and making maps days before as they worked to test the Oxcart’s inertial navigation system, or INS. “When you’re flying at that altitude and that speed, you need big checkpoints to validate information from the INS,” recalls navigator Sam Pizzo. “Any old geographical landmark, like a mountain or a river, would not do. The Oxcart traveled too fast. Pilots would have to look for landmarks on the scale of the Grand Canyon or the Great Lakes,” says the veteran navigator. “You can’t imagine what new territory this was for a navigator. No amount of experience can prepare you when you work on an airplane that goes two or three times as fast as anything you navigated for before.”

After Oxcart pilot Kenneth Collins’ experimental spy plane crashed, Annie Jacobsen explains (in Area 51), the CIA redoubled its efforts to keep the project secret:

Declassified in 2007 and never before made public, the CIA had been monitoring phone conversations of journalists who seemed interested in the Oxcart program. “Mr. Marvin Miles, Aviation Editor, Los Angeles Times, telephonically contacted Westinghouse Corp., Pittsburgh, attempting to confirm if employees of that firm were traveling covertly to ‘the desert’ each week in connection with top secret Project which he suspects may have ‘CIA’ association,” read one memo. Another stated that “Mr. Robert Hotz, Editor Aviation Week, indicated his awareness of developments at Burbank.” Of particular concern to the Agency was an article in the Hartford Courant that referred to the “secret development” of the J-58 engine. Another article in the Fontana, California, paper the Herald News speculated about the existence of Area 51, calling it a “super secret Project site.” An increasingly suspicious CIA worked overtime to monitor journalists, and they also monitored regular citizens, including a Los Angeles–based taxi driver who was described in a memo marked “classified” as once having asked a Pratt and Whitney employee if he was “en route to Nevada.”

The Agency should have been more concerned about its rival:

Just as it had with the U-2, the Pentagon moved in on the CIA’s spy plane territory. Only with the Oxcart, the Air Force ordered not one but three Air Force variants for its stable. One version, the YF-12A, would be used as an interceptor aircraft, its camera bay retrofitted to hold two 250-kiloton nuclear bombs. The second Oxcart variant the Air Force ordered could carry a drone on its back. The third was a two-seater version of the CIA’s stealth spy plane, only instead of being designed to conduct high-speed, high-altitude reconnaissance missions over enemy territory during peacetime, the Air Force supersonic spy plane was meant to go in and take pictures of enemy territory immediately after a nuclear strike by U.S. bomber planes—to see if any strategic targets had been missed. Designated the RS-71 Blackbird, this now-famous aircraft had its letter designation accidentally inverted by President Lyndon B. Johnson in a public speech. Since the president is rarely ever “corrected,” the Air Force changed its letter designation, which is how the SR-71 Blackbird got its name. (Originally, the letters stood for “Reconnaissance/ Strike.”)

[…]

The Air Force had already spent eight hundred million dollars developing the B-70 bomber airplane — a massive, triangle-shaped, Mach 3, six-engined bomber that had been General LeMay’s passion project since its inception in 1959. When a fleet of eighty-five of these giant supersonic bombers was first proposed to Congress, LeMay, then head of the Strategic Air Command, had his proposition met with cheers. But the Gary Powers shoot-down in May of 1960 had exposed the vulnerability of LeMay’s B-70 bombers, which would fly at the same height as the U-2. In 1963 LeMay was no longer head of the Strategic Air Command — instead, he was President Kennedy’s Air Force chief of staff. Despite evidence showing the B-70 bomber was not a practical airplane, LeMay was not about to give up his beloved bomber without a fight.

When the CIA first briefed President Kennedy on how high and how fast the A-12 Oxcart would fly, the president was astonished. His first question, according to CIA officer Norman Nelson, was “Could it be converted into a long-range bomber to replace the B-70?” LeMay was in the room when Kennedy asked the question. The thought of losing his pet program to the Agency drove General LeMay wild. He lobbied the Pentagon to move forward with the B-70, and he stepped up his public relations campaign, personally promoting the B-70 bomber program in magazine interviews from Aviation Week to Reader’s Digest. He was committed to appealing to as many Americans as possible, from aviation buffs to housewives. But by 1963, Kennedy was leaning toward canceling the B-70. In a budget message, he called it “unnecessary and economically unjustifiable.” Congress cut back its B-70 order even further. The original order for eighty-five had already been cut down to ten, and now Congress cut that to four.

[…]

“Johnson, I want a promise out of you that you won’t lobby anymore against the B-70,” LeMay said. Provided Kelly Johnson complied, LeMay promised to send Lockheed an Air Force purchase order for an interceptor version of Lockheed’s A-12 Oxcart, in addition to the preexisting order. For Lockheed, this would mean a big new invoice to send to the Air Force. At first, Kelly Johnson was suspicious of LeMay’s sincerity. That changed just a few weeks later when Secretary of Defense Robert McNamara showed up at the Skunk Works with the secretary of the Air Force and the assistant secretary of defense in tow. Now McNamara asked for a briefing on the A-12, during which he took “copious notes.” Within a matter of months, the Pentagon ordered twenty-five more A-12 variants. The Pentagon already had a catchy name for its versions of the Oxcart. They would call them Blackbirds. Black because they had been developed in the dark by the CIA, and birds because they could fly.

[…]

The CIA did all of the heavy lifting to get the aircraft aloft, only to have the program eventually taken over by the Pentagon for the Air Force.

Oxcart pilot Kenneth Collins was taking the experimental spy plane out for a subsonic test run, like a race horse out for a trot, Annie Jacobsen explains (in Area 51), when something went wrong:

“Suddenly, the altimeter was rapidly unwinding, indicating a rapid loss of speed,” Collins recalls. In heavy clouds, Collins had no visual references to determine where he was. “I advanced the throttles to counter the loss of airspeed. But instead of responding, and without any warning, the aircraft pitched up and flipped over with me trapped underneath. Then it went into an inverted flat spin.” The Agency’s million-dollar A-12 Oxcart was unrecoverable and crashing. Collins needed to bail out.

Collins had no idea how close he was to the Earth’s surface because he was in the middle of a cloud and couldn’t see out of it. He also did not know if he was over a mountain range, which would mean he had even less time to eject. Collins closed his visor and grabbed the ejection ring that was positioned between his legs. He pushed his head firmly against the headrest and pulled. This kind of radical ejection from a prized top secret aircraft is not easy to forget, and Collins recalls dramatic details. “The canopy of the aircraft flew off and disappeared but I was still upside down, with the aircraft on top of me,” he explains. “Having pulled the D-ring, my boot stirrups snapped back. The explosive system in the seat rocket engaged, shooting me downward and away from the aircraft.” First Collins separated from the Oxcart. Next he separated from his seat. After that, he was a body falling through the air until a small parachute called a drogue snapped open, slowing his body down. In his long history of flying airplanes, this was the first time Collins had ever had to bail out. Falling to Earth, he tried to get a sense of what state he might be over. Was he in Nevada or Utah? The ground below him appeared to be high-desert terrain, low hills but no mountains that he could see. He was still too high up to discern if there were roads. As he floated down, in the distance he spotted the heavy black aircraft tumbling through the air until it disappeared from sight. “I remember seeing a large, black column of smoke rise up from the desert floor and thinking, That’s my airplane.” Only now there was nothing left of it but an incinerated hunk of titanium smoldering on the ground. Fate was a hunter, all right.

[…]

Collins unclipped himself from the parachute and began collecting everything around him. Flight-protocol pages and filmstrips of navigational maps fluttered across the desert. As he hurried to collect the top secret papers, he was surprised to hear a car motor in the distance. Looking up, he saw a pickup truck bouncing toward him along a dirt desert road. “As it got closer, I could see there were three men in the front cab,” Collins recalls. “The truck pulled alongside me and came to a stop. I could see they had my aircraft canopy in the back of their pickup.”

The men, who appeared to be local ranchers, sized up Collins. Because the flight had been subsonic, Collins was wearing a standard flight suit and not a high-altitude pressure suit, which would have made him look like an astronaut or an alien and likely prompted a lot more questions. Instead, the ranchers asked Collins if he wanted a ride. They said they knew exactly where his airplane had crashed, and if he hopped in, they’d give him a ride back to his plane. Until that moment, no civilian without a top secret security clearance had ever laid eyes on the Oxcart, and Collins had strict orders to keep it that way. He’d been briefed on what to do in a security breach such as this one, given a cover story by the Agency that fit perfectly with the proximity to the Nevada Test Site—and with the times. Collins told the ranchers that his aircraft was an F-105 fighter jet and that it had a nuclear weapon on board. The men’s expressions changed from helpful to fearful. “They got very nervous and said if I wanted a ride, I better jump in quick because they were not staying around Wendover for long,” Collins recalls.

The ranchers drove Collins to the nearest highway patrol office. There, he jumped out, took his airplane canopy from the back of the truck, and watched the men speed off. Collins reached into the pocket of his flight suit. Inside, he found the note that read call this number, followed by a telephone number. Also in his pocket was a dime. Inside the highway patrol office, Collins asked the officer on duty where he could find the nearest pay phone. The man pointed around to the side of the building, and using the Agency’s dime, Collins made the phone call that no Agency pilot ever wants to make. A little less than an hour later, Kelly Johnson’s private airplane landed in Wendover, Utah, along with several men from the CIA. After a brief exchange of words so Kelly Johnson could confirm that Collins was physically okay, Collins boarded the airplane. During the two-hour flight to the Lovelace Clinic in New Mexico, no one said a word. “There would be plenty of talking to do during the debriefing,” Collins says, “and with the Agency’s tape recorders taking everything down.” A crash of a CIA spy plane meant someone had some explaining to do.

[…]

“Maintenance guys, security guys, navigators, we all took off in trucks and airplanes and headed to Utah,” Pizzo explains. With Collins confirmed alive, the goal now was to locate every single piece of the wrecked airplane, “every nut, bolt, and sliver of fuselage.”

[…]

Once they found the site, the work crew had a lot of digging to do. The aircraft, Article #123, hadn’t broken apart in flight, but given the speed at which it had hit the earth, huge sections of the airplane had become buried. Critically important was locating every loose piece of the titanium fuselage. The metal was rare and expensive, and the fact that the Agency’s spy plane was hand-forged from titanium was a closely held secret. If a news reporter or a local got a hold of even the smallest piece of the aircraft, its unusual composition would raise questions that might threaten the cover of the entire Oxcart program. Equally critical to national security was making sure the radar-absorbing materials, known as composite and that covered the entire airplane, remained in government control. If a piece of the plane got into the wrong hands, the results could be disastrous: the Russians could learn the secret of stealth.

Along with a crew of more than one hundred men, the Agency brought its own horses to the crash site. Men from Groom Lake took to the desert terrain on horseback and began their search.

[…]

In Air Force culture, when an airplane crashes, someone has to take the blame. Collins explains: “In the SAC [Strategic Air Command] mind-set, if there’s an accident, the wing commander suffers the consequences.” Instead, Collins believes, Holbury tried to get Collins to be the fall guy. “Holbury didn’t want blame; he wanted a star. He wanted to become a general, so he tried to put the blame on me. After the crash, even before the investigation, he requested that I be fired.”

Collins was unwilling to accept that. Fortunately for Collins’s career, Kelly Johnson, the builder of the aircraft, didn’t care about blame as much as he wanted to find out what had gone wrong with his airplane. Listening to Collins describe what had happened during the debriefing, Johnson couldn’t figure out what caused the aircraft to crash. He wondered if there was something Collins had forgotten, or was maybe leaving out. “I was clear in my mind that the crash was a mechanical error and not a pilot error,” Collins explains. “So when Kelly Johnson asked would I try unconventional methods like hypnosis and truth serum, I said yes. I was willing to do anything I could to get to the truth.” While the Pentagon’s accident board conducted a traditional investigation, Collins submitted to a far less conventional way of seeking out the truth of the cause of the crash.

Inside the flight surgeon’s office at Lockheed, Collins sat with a CIA-contracted hypnotist from Boston, “a small, rotund man dressed in a fancy suit,” as Collins recalls. “He tried very hard to put me in a trance, only it didn’t work. I don’t think he realized that hypnotizing a fighter pilot was not as easy as he thought it might be.” Next, Collins was injected with sodium thiopental, also known as truth serum. Collins remembers the day well. “I told my wife, Jane, I was going to work for a few hours, which was unusual to begin with because it was a Sunday. The point of the treatment was to see if I could remember details other than those I relayed in the original debrief with the CIA. But yes, even with the sodium pentothal in my system, everything I said was exactly the same. The treatment takes a lot out of you and after it was over, I was very unsteady on my feet. Three CIA agents brought me home late that Sunday evening. One drove my car, the other two carried me inside and laid me down on the couch. I was still loopy from the drugs. They handed Jane the car keys and left without saying a word.”

[…]

After a lengthy investigation it was determined that a tiny, pencil-size part called a pitot tube had in fact caused the crash. The pitot tube measured the air coming into the aircraft and thereby controlled the airspeed indicator. Unlike in a car, where the driver can feel relative speed, in a plane, without a proper reading from an airspeed indicator, a pilot has no awareness of how fast he is going, and without correct airspeed information a pilot cannot land. When Collins flew into the cloud, the pitot tube reacted adversely to the moisture inside and froze. The false airspeed indicator caused the aircraft to stall. As a result of the stall, the Oxcart flipped upside down and crashed.
