Though it was a powerful, almost beautiful sight, Dirk felt a sickening knot in his stomach as he watched the rocket ascend. The glistening white missile would host the most savage terrorist attack the world had ever seen, resulting in a horrifying death for millions. And he had failed to stop it. As if that was not punishment enough, he knew that Sarah was somewhere in the target area of Los Angeles and might very well be one of the strike's first victims. And then there was the fate of his father. Glancing forlornly at Giordino, he saw a grimace on the old Italian's face the likes of which he had never seen before. It was not a look of anger with the terrorists but an expression of concern for the loss of a lifelong friend. As much as Dirk did not want to face it, he knew that amid the noxious inferno of the rocket's blastoff his father was somewhere on the platform fighting for his survival, or worse.
Aboard the Deep Endeavor, Summer felt the same pangs of dread swell through her body. Dirk had radioed the ship with news that the Sea Launch crew had been rescued, but also that their father was somewhere aboard the platform. When Delgado was the first to observe the rocket igniting, she thought her legs had turned to rubber.
Grasping the captain's chair for support, she stared stoically toward the platform as tears welled in her eyes. All fell silent on the bridge around her as they watched in disbelief at the rocket as it surged off the launchpad. As one, their thoughts were on the fate of the NUMA leader, lost somewhere in the rocket's white plume of smoke. “It can't be,” Burch muttered in shock. “It just can't be.”
Inside the Badger, the temperature was unbearable. The superheated metal skin created a sauna effect with the water that was rising inside. Pitt could feel himself on the verge of passing out from the heat as he clawed his way back to the tilted pilot's seat. A handful of lights still blinked on the control panel, indicating that the emergency life-support system still had power, but the propulsion systems were long expired. Though his body was numb from the heat, his mind quickly calculated that he had one chance to break free from the grip of the pontoon. Through sweat-laden eyes, he reached forward and mashed a control button market ballast pump. Then, grasping the control yoke, he flung himself backward into the rising water, using his full weight and remaining strength to yank the sub's rudder against the burgeoning current. The rudder blade protested at first, then swung slowly against the rushing water, fighting against Pitt's every movement. With muscles aching and spots appearing before his eyes, Pitt clung desperately to the yoke, fighting not to pass out. For a second, nothing happened. All Pitt could hear was the churning torrent of the water rushing against the sub, while the temperature inside continued to rise. Then, almost imperceptibly, a grinding noise struck his ears. Gradually, the noise grew louder, matching the sound he had heard before. A faint smile crossed Pitt's lips as he fought to maintain consciousness. Hang on, he told himself, gripping the yoke tightly. Just hang on.
An eagle-eyed flight engineer, standing on a rocky hilltop of Santa Barbara Island amid his stunned Sea Launch colleagues, was the first to detect it. A subtle, almost invisible waggle at the base of the rocket as it cleared the launch tower.
“She's oscillating,” he said aloud.
His surrounding crewmates, exhausted and stunned by the entire ordeal, ignored his words and watched in angry disbelief as somebody else launched their rocket from their platform. But as the rocket climbed higher and higher into the sky, more of the experienced launch veterans detected something amiss with the flight trajectory. At first, just a murmur rippled through the assembled crew; then, an excited buzz jolted the men like an electric shock. One man started to yell, cursing at the rocket to burst, and then another followed suit. Before long, the entire crew was jumping up and down while shouting at the soaring rocket, cajoling the mechanical beast like some last-dollar bettors urging a long-shot nag to the wire at Pimlico.
On board the Koguryo, the excitement of the launch had yet to wane when a seated flight engineer turned to Ling and said, “Sir, the Stage One engine indicates an active gimbaling beyond nominal flight plan parameters.”
The Zenit-3SL, like most modern rockets, was steered in flight by adjusting, or gimbaling, the launch vehicle's engine, redirecting its thrust to govern the rocket's heading. As Ling was aware, the initial launch sequence called for no gimbaling until the rocket was in a stabilized climb, then the navigation system would initiate slight steering adjustments to guide the rocket toward the target. Only an undetected imbalance would create an immediate steering correction from launch.
Ling walked over to the engineer's station and peered at the man's computer monitor. His mouth fell open as he saw that the rocket's engine was gimbaled to its maximum degree. He watched in silence as, a second later, the engine adjusted back to its neutral position, then gimbaled to the full extent in the opposite direction. Almost immediately, the whole cycle started over again. Ling immediately surmised the cause.
“Choi, what was the launchpad horizontal deviation at T-0?” he shouted to the platform engineer.
The engineer looked back sheepishly at Ling and uttered in a barely audible voice, “Sixteen degrees.”
“No!” Ling gasped in a raspy voice as his eyes scrunched closed in a panic of disbelief. The color rushed from Ling's face and he felt himself grasping the computer monitor to steady his suddenly weakening knees. With dire foresight, he slowly opened his eyes and stared at the video screen of the charging rocket, waiting for the inevitable.
Pitt had no way of knowing the impact from his frenetic hole drilling. But the dozens of gouges poked into the side of the support columns had opened up a flood of incoming seawater that quickly overpowered the Odyssey's ballast pumps. With the automated controls set to maintain the prescribed launch depth, the incoming water collected in the rear support columns and tugged the platform down by its aft side. Firing off the platform, the Zenit rocket was over fifteen degrees off vertical center as it left the launchpad and immediately tried to correct the deviation from its prescribed flight plan by shifting the engine thrust. But at the low speed of takeoff, the initial command was diluted so the engine position was tweaked again to its maximum adjustment. As the launch vehicle gained speed, the adjustment quickly became an over correction and the rocket's computers gimbaled the engine in the opposite direction to counterbalance the movement. Under normal conditions, the rocket might have been able to stabilize itself with a few minor adjustments. But on this flight, the Zenit's fuel tanks were only half full. The partially empty fuel tanks allowed the liquid propellant to slosh back and forth during the thrust inclinations, creating a whole new set of balancing dynamics. The overtaxed stabilization control system tried vainly to smooth the flight but, ultimately, exacerbated the situation and the rocket began to waffle.
On video screens and satellite feeds, out an airship cockpit window, and from a barren rocky island in the Pacific Ocean, a thousand eyes stared transfixed at the streaming white rocket as it began a slow and morbid gyration across the sky. What started as a slight wobble at liftoff grew into a continuous waggle during ascent until the entire rocket was shaking uncontrollably toward the clouds like an anorexic belly dancer. Had Sea Launch been managing the flight, an automated safety control would have detonated the rocket as it veered out of parameter. But the abort command had been deleted from the flight software by Kang's crew and the Zenit was left to struggle upward in a tortuous dance of death.
To the unbelieving sight of those who watched, the huge rocket swung wildly in the sky before tearing itself apart from the inside out and literally snapping in two. The lower Stage immediately disintegrated in a massive fireball as the fuel tanks were simultaneously ignited, swallowing everything in its radius with a cauldron of flame. Chunks and pieces of rocket machinery not dissolved by the explosion rained down over a swath of empty sea, while the high-altitude mushroom cloud from the explosion hung in the blue sky as if painted there.
