Swarms of men were making the planes ready. Tracks filled each with fourteen tons of jet fuel and half a ton of coolant alcohol and pumped oxygen into life-support systems. From smaller trucks bearing electronic test equipment, technicians checked the missiles, fire control, and electronic systems. Others stepped under and around the planes, physically inspecting the exterior surfaces and controls.
Belenko climbed a fourteen-foot metal ladder, followed by his flight engineer, who helped him settle into the green cockpit, green because Soviet researchers believed it the most soothing color. The cushioned seat was the most comfortable in which he ever had sat. The various dials, gauges, buttons, and levers were well arranged and easily accessible. Conspicuous among them was a red button labeled «Danger.» Pilots were instructed that should they be forced down or have to eject themselves from the aircraft outside the Soviet Union, they must press the button before leaving the cockpit. Supposedly it activated a timing device which a few minutes later would detonate explosives to destroy the most secret components of the plane. Some fliers wondered, however, whether a press of the button might not instantly blow up the entire aircraft, pilot included. He also dared not touch the radar switch because the impulses from the MiG-25 radar were so powerful they could kill a rabbit at a thousand meters. Hence, it was a crime to activate the radar on the ground.
Turning on his radio, Belenko spoke to the control tower. «This is Number Oh-six-eight. Request permission to start engines.»
The tower answered quickly. «Number Oh-six-eight, you have permission to start engines.»
«Understood. I am executing,» Belenko said, waving to his flight engineer, who backed down the ladder, ordered the ground crew to remove the engine covers, and signaled that the hydraulic systems were functioning. As Belenko flicked switches and pushed buttons, the engines produced a soft whine that soon swelled into a roar. «This is Oh-six-eight,» Belenko radioed the tower. «I request permission to taxi.»
«Oh-six-eight, you have permission.»
«Understood. I am executing.»
Belenko taxied the MiG-25 to the end of the taxi ramp about half a mile away. Four MiGs were ahead of him, and he had to wait until a green light authorized him to turn onto the runway. «This is Oh-six-eight. Request permission to take off.»
«Oh-six-eight, you have permission.»
«Understood. I am executing.»
He hesitated a few seconds to look once more at the surrounding forests. Above all else in his homeland, he loved the rugged, open expanses and the forests where he had wandered since boyhood. There he could explore and discover and meditate, be alone with a girl or with himself. Only there and in the cockpit had he ever felt free. Under brilliant sunshine, the leaves were turning copper, gold, and ruby, and he thought that the forest never had appeared more majestic, never more impervious and antithetical to human squalor.
With ignition of the afterburner, the aircraft vibrated, bucked, and strained forward. «Oh-six-eight, you have afterburn,» the tower confirmed. «We wish you all good.» Belenko released the brakes at exactly 12:50 P.M., and the MiG surged down the runway and within fifteen seconds into the air. While still perilously low, he shut the afterburner prematurely to conserve fuel, which was precious, so precious that he gladly would have exchanged some of his own blood for extra fuel. Also to conserve, he ascended more slowly than usual to 24,000 feet and took five minutes instead of the normal four to enter Training Zone No. 2 on a course of 090 degrees. Beginning the wide 360-degree turn which ground controllers were expecting of him, he saw numerous other MiG-25s in the area, fully armed and fueled. The needle, rotating swiftly around the compass dial with his continuous change in heading, showed that he rapidly was approaching the point of no return. For upon completion of the circle, he would have to proceed either with the programmed flight or with his own.
You can still go back, and nobody will know. If you go, it's forever. I'm going.
Now he began his own secret flight plan.
Back on a course of 090, he let the plane glide downward, hoping the descent would be so gradual the radar controllers would not at once notice. At 19,000 feet, Belenko suddenly jammed the stick forward and to the left and plunged the MiG into a power dive toward the floor of a valley ahead, shrieking and hurtling straight down so that the whole earth seemed to be jumping right into his face until he managed to level off at 100 feet. Never had he attempted such a dive, nor had he ever tried to fly a MiG-25 so low, for below even 1,000 feet it was clumsy and difficult to control. Yet from study of American tactics in Vietnam, he knew that at 100 feet he would be safe from the thickets of SAMs (surface-to-air missiles) and antiaircraft batteries emplaced on the peaks of the valley and that these bristling peaks would hide him from radar.
Applying power, he thundered through the valley and in two minutes shot out over the Sea of Japan. He pushed an emergency button which started broadcasting a continuous signal indicating his plane was on the verge of crashing. After about forty seconds he turned off the signal to persuade all listening on the distress frequency that it had crashed. Simultaneously he shut down his radar and all other equipment whose electronic emissions might be tracked. Lastly, he switched off his radio, even though it gave off no emissions. He did not want to be affected or distracted by what they might be saying, what they might be doing, how they might be pursuing. He needed now to concentrate purely and intently on the equations of fuel, speed, altitude, time, and distance, which he calculated mainly in his head, aided by only a pencil and tablet. Perhaps use of the cockpit computer would have been more practical and efficient. But he was resolved, as he had done in all crises of his life, to rely on, to trust only himself.
To evade detection by the long-range radars back on land and the missile-carrying Soviet ships patrolling offshore, Belenko flew so low that twice he had to swerve to avoid hitting fishing vessels. Only when he perceived that the waves were rising so high that he might smash into one did he go to a slightly safer altitude of 150 feet.
Along with mounting waves, he encountered darkening skies and rainsqualls which buffeted the plane and portended worsening weather ahead. His mental computations portended much worse. At sea level the MiG was devouring fuel at a fatally gluttonous rate, far exceeding preflight estimates. Rapid recalculations yielded the same grim results. Unless he drastically reduced fuel consumption at once by assuming an altitude of at least 20,000 feet, he never would make landfall. Yet he had not flown far enough to go up safely to that height. He still would be within reach of Soviet radars and SAMs. He also might be picked up on the radars of other Soviet aircraft hunting to rescue him, had he survived a crash at sea, or to kill him, were he still aloft.
Better possible death than certain death, Belenko reasoned, pulling up into the clouds, which quickly encased him in darkness. He had flown on a southeasterly course, dead reckoning his way toward Hokkaido, the northernmost of the Japanese islands and the one closest to his base. At approximately 1:20 P.M. — just thirty minutes after takeoff — he figured he was nearing Japanese airspace and interception by Phantom fighters of the Japanese Air Self-Defense Force. To signify lack of hostile intent and facilitate interception, he throttled back the engines and glided down toward Japan, scarcely sustaining airspeed. Each moment he hoped to break free of the clouds and into the clear, where the Phantoms could see him.
