The agency was unhappy about being upstaged by the Air Force. CIA personnel were still responsible for servicing the spy planes at McCoy and taking charge of the intelligence materials. The Air Force pilots regarded them as interlopers, “looking for fault in everything we did.” CIA officials complained that the Air Force did not pay enough attention to the threat posed by the SAM sites. There was no system for using electronic warfare techniques to jam the radars used by the Soviet air defense system or to track the U-2s as they flew over Cuba. Intelligence officers estimated the chances of a U-2 pilot being shot down over Cuba as around one in six.
Anderson climbed up the steps to the U-2 followed by his mobile control officer and strapped himself into the cockpit. He carried photographs of his wife and two young children in his wallet. He was still feeling some pain in his right shoulder caused by a fall on the ice while on temporary duty in Alaska, but he was not going to let that stop him from flying. When his commander pulled him off the flight schedule one day to give him some rest, he had complained vociferously. “Aren’t I doing a good enough job?” he wanted to know.
The mobile officer, Captain Roger Herman, ran through the final checklist. Herman made sure that Anderson’s oxygen supply was connected properly and that the maps and “top secret” target folder were all neatly stacked by the side of the ejector seat. The two pilots tested the emergency systems to make sure they were functioning normally. A surge of oxygen briefly inflated the capstans on Anderson’s partial-pressure suit, filling the cockpit. When he was certain that everything was in order, Herman slapped Anderson on the shoulder.
“Okay, Rudy, here we go, have a good trip. See you when you get back.”
Anderson gave a thumbs-up sign as Herman closed the canopy. Moments later, his U-2 took off for Cuba. It was 9:09 a.m.
At the time that Anderson took off, an American electronics reconnaissance plane had already been in the air for four hours. The RB-47, a modified version of the B-47 bomber, was ferreting out Soviet radar signals. Captain Stan Willson had taken off at five o’clock that morning from Forbes Air Force Base in Kansas, topped up his fuel tank over the Gulf of Mexico, and was now circling Cuba, taking care to remain over international waters. Although he was interested in any type of radar signal, his primary goal was to find out whether Soviet air defenses had been activated.
In addition to two pilots and a navigator, the crew of the RB-47 included three electronic warfare officers. In official Air Force lingo, they were known as “ravens,” but they preferred a more humorous, self-deprecating term, “crows.” Shortly after the plane got in the air, but before it reached altitude, the ravens had crawled back to the converted bomb bay, now stuffed with electronic eavesdropping equipment. Protruding like a pregnant womb from the underbelly of the plane, the “crows’ nest” was sealed off from the pilot’s compartment and pressurized separately. The ravens would spend the next ten hours listening to a series of beeps and twitters over the airwaves.
For the most part, it was boring work, punctuated by moments of intense activity. Many of the men on Willson’s plane had flown peripheral missions around the Soviet Union, probing for weaknesses in the air defense system in advance of a possible bomber attack. They would aim directly for the Soviet frontier, as if they were on a bombing raid, and then veer away at the last moment. The idea was to provoke the Russians to switch on their radars. The intercept data could be used later to map the Soviet air defense system. There was always a risk that they would stray over Soviet territory and be shot down. Several members of Willson’s outfit—the 55th Strategic Reconnaissance Wing—had ended up in Soviet prisons, while others had been killed by the very weapons systems they had been sent to detect.
The flights around Cuba were known as “Common Cause.” Some thrill-seeking ravens had begun to refer to the missions as “Lost Cause.” Entire days could go by without anything happening. For one RB-47 pilot, the defining sound of the Cuban missile crisis was the “noise of silence.” Both sides remained off the airwaves for as long as they could in order to give away as little information as possible to the enemy. Normally there was “a lot of chatter,” but now everybody seemed to be “holding their breath.”
On Saturday morning, the airwaves came alive again, as the Soviets turned on their air defense tracking system. When the ravens picked up a radar signal, they immediately turned on their tape recorders and scanners. Analyzing radar signals was a cross between monitoring a cardiogram and studying birdsong. Just as experienced birders can make out hundreds of different varieties of birds, ravens learned to distinguish between different types of radar system, and even imitate them. Early warning radars produced a low-pitched sound, with considerable distance between the pulses. Fire-control radars emitted a shriller, almost continuous squeal, like the chirping of a bird. When a raven heard one of those, he knew that his own plane was in danger of being targeted. The pilot was authorized to “fire to destroy” if he thought he was coming under attack.
As Willson’s RB-47 flew around the coast of Cuba, the ravens began picking up radar signals associated with different Soviet missiles. They identified the telltale brrr-brrr of a Spoon Rest, the target acquisition radar for the Soviet SAM system. The spy ship Oxford had picked up similar signals overnight from the middle of the Florida Straits, an early indication that the Soviets had finally decided to activate their air defense system.
Hunched over their monitors, the ravens suddenly heard the high-pitched zip-zip-zip of a fire-control radar. Using their direction-finding equipment, a spinning antenna in the underbelly of the plane, they were able to trace the source of the signal. It was coming from a previously identified SAM site a few miles outside the town of Banes in eastern Cuba. The implications were ominous: American planes overflying Cuba were not just being tracked by Soviet air defenses. They were being targeted.
The senior raven flicked the switch on the intercom connecting the crows’ nest to the cockpit above. “Hey boss, we have a Big Cigar.”
“Big Cigar” was the official code word for a Fruit Set fire-control radar. The copilot relayed the information to the Strategic Air Command, but there was no way he could get in touch with Anderson directly to warn him of the danger. The U-2 pilot was observing strict radio silence.
After eleven years in the Air Force, Chuck Maultsby had a reputation as an outstanding pilot. He had served two years with the Thunderbirds, the Air Force acrobatic team, maneuvering his F-100 Super Sabre through a series of spectacular loops, rolls, and corkscrews. He flew Right Wing in the four-plane formation. Prior to that, he had survived six hundred days as a Chinese prisoner of war after being shot down in combat over North Korea. With his trim mustache, darkly handsome face, and amused eyes, he looked like a shorter version of the British actor David Niven. He exuded confidence and competence. Like most Air Force top guns, Maultsby firmly believed that he could “whip anybody else in an air fight.”
Right now, however, he was feeling anything but confident. According to his flight plan, he should have been on his way back to Alaska. But stars kept popping up in unexpected places. He wondered if something had gone “terribly wrong.”
Maultsby was relying on the age-old techniques of celestial navigation—methods used by Magellan and Christopher Columbus—to keep himself oriented. Navigators had prepared a stack of celestial charts for various points along his route. The pilot kept the charts stacked by his seat. When he was halfway to the pole from Barter Island, he pulled out the stiff green card that showed his assumed position and the precise alignment of the stars for this particular time of night. If he was on track, the soft orange light of Arcturus, the brightest star in the northern hemisphere, should have been visible to the right of the plane’s nose. Another bright star, Vega, would be located slightly higher up in the sky, toward the northwest. The northern star, Polaris, would be almost directly overhead, indicating that he was getting close to the North Pole. The constellation Orion, the Hunter, would be behind him, toward the south.
