"Everybody to this end of the chamber, if you're able," she shouted to the others after groping her way to one end. "We must shift the weight."
Her dazed and battered companions crawled their way to Theresa, huddling together quietly while trying to aid one another's injuries in the dark. The thousand pounds of shifted weight alone might not have set them free, but Theresa had guessed right and placed everybody adjacent to what had been the stern edge of the boat. Above their heads now was the boat's engine, the heaviest part of the stern section.
The combined concentration of weight was focused just off of dead center, and slight enough, to create an angular imbalance in the sinking wreckage.
As the plunging boat drove deeper, the pressure from the depths increased. Creaking sounds wafted through the chamber as the pressure limits were approached in its welded seams. But the shift in ballast gradually weighed on the angle of descent, tipping the stern section of the boat slightly steeper. Inside the chamber, nobody could feel the shift, but a slight scraping sound was heard as the chamber began sliding across the angled deck. The movement accelerated the imbalance until the chamber perceptively tipped upward. The gradient increased to almost forty degrees before the decompression chamber finally rattled off the stern edge and broke free of the sinking wreckage.
To those inside the chamber, it felt like a roller-coaster ride in reverse, as the buoyant capsule shot to the surface like a bullet. To Giordino, who scanned the lake surface high above in the Kamov, the sight reminded him of a Trident missile being launched from a submerged Ohio-class nuclear submarine. After watching the wave pass and the bow section sink, he'd noticed a large surge of bubbles nearby. At a depth of eighty feet, he perceived, the white decompression chamber accelerating toward the surface.
Released from the depths at a tilted angle, the chamber broke the surface nose first and shot completely out of the water before slamming down violently onto the surface. Hovering closer, Giordino could see that the chamber appeared airtight and floated easily in the light choppy waves.
Despite a severe battering, Theresa could hardly contain her relief at seeing blue sky again out the chamber's porthole window. Peering out the view port, she could see that they were floating steadily on the water. A shadow passed by overhead, and she caught a reassuring glimpse of the silver helicopter.
With newfound light illuminating the interior again, she turned and surveyed the tumbled mass of bodies crowded around her.
The tumultuous ride had bruised and battered everyone, but amazingly there were no serious injuries.
The fishing boat's captain bled from a nasty gash to the forehead, while Wofford grimaced over a wrenched back. Roy and the two women managed to escape lasting injuries. Theresa wondered how many concussions and broken bones would have occurred had they not insulated themselves with the bed mattresses just before the wave struck. As she regained her senses, her thoughts drifted back to Pitt, wondering whether the man who had rescued them had himself survived the maelstrom.
The veteran head of NUMA had figured he could best beat the wave in open water. An experienced body surfer since his childhood days growing up in Newport Beach, Pitt knew that diving under the approaching wave would let it roll over him with minimal surge. After securing the survey team inside the decompression chamber, he'd quickly strapped on his faceplate attached to a Drager rebreather system and dropped over the side of the fishing boat. Hitting the water, he kicked and pulled hard, attempting to swim away from the fishing boat and dive beneath the wave before it struck. But he'd been just a few seconds too late.
The seiche wave broke over him just as he cleared the surface. Rather than escape under the passing wave, he was positioned too shallow and found himself being drawn up the face of the wave. The sensation was of riding an ascending elevator at high speed and Pitt felt his stomach drop as his body was sucked upward. Unlike the fishing boat, which rode the external surface of the wave before breaking up, Pitt was embedded within the mass of water and became part of the wave itself.
His ears rang from the rush of the mammoth wave while the turbulence of the roiling water dropped the visibility to zero. With the rebreather system on his back, he was able to breathe normally through his faceplate despite the tempest around him. For a moment, he felt like he was flying though air and a part of him actually enjoyed the ride, though the danger of being crushed under the wave gnawed at his senses. Trapped in the uplift, he realized there was no sense in fighting the overpowering force of water and relaxed slightly as he was pushed higher. He had no sensation of any forward motion, despite the fact he had already been carried several hundred yards from the point he entered the water.
As he zoomed upward, he suddenly felt a leg break free of the water, then a flash of light burst through his faceplate as his head broke the surface. His momentum shifted, and now he felt his body getting tugged forward. He instantly realized that he had been pushed to the very top of the wave and was in danger of getting hurled over the wave's leading edge. Just inches away, the peak of the wave dropped over thirty feet in a vertical wall of water to the lake surface. A torrent of white foamy water curled around him as the wave began showing signs of cresting. Pitt knew that if he fell over the precipice and the wave crested on top of him, he could be crushed to death under a mass of falling water.
Pivoting his body perpendicular to the wave front, he flung his arms through the water and kicked with all his might to swim over the top of the wave. He could feel himself being pulled backward from the momentum of the wave and willed his legs to kick harder against the water. With the frenzy of a sprint swimmer, he lunged over the wave crest, arms and legs flailing at a supersonic rate. The rushing water continued to pull at his body, trying to suck him into the morass, but he willed himself on desperately.
Then suddenly the grip released and the wave seemed to let go beneath him. He felt himself falling headfirst, which meant he had made it to the backside of the wave. The elevator ride zipped down this time, but in a controlled free fall. He consciously tensed for an impact, but it never arrived. The rushing force of water eased, then dissipated to nothing. In a froth of clearing bubbles, Pitt found himself floating freely underwater. As the loud rush of the wave diminished, he glanced at a depth gauge affixed to his harness and found that he was twenty feet under the surface.
Reorienting himself in the water, he eyed the shimmering lake surface above him and lazily kicked with tired legs until his head broke the water. Gazing toward the still-thundering rumble, he watched as the massive wave rolled rapidly toward its destructive rendezvous with the south shoreline. The roar slowly faded, and Pitt's ears detected the rotor-thumping sound of a helicopter take its place. Turning in the water, he saw the Kamov helicopter low in the sky making a beeline toward him. Scanning the lake, he saw no sign of the fishing boat on the horizon.
Giordino brought the Kamov right alongside Pitt, hovering so low that waves washed over the helicopter's landing wheels. Pitt swam to the cockpit as the passenger door was flung open above his head. Climbing up the landing skid, he hauled himself through the door and onto the passenger's seat.
Giordino immediately elevated the helicopter as Pitt removed his faceplate.
"Some guys will do anything to hang ten," Giordino grinned, relieved to have found his friend in one piece.
"Turned out to be a lousy pipeline," Pitt gasped in exhaustion. "The fishing boat?"
Giordino shook his head. "Didn't make it. Snapped in two like a twig. Thought we lost the decompression chamber, too, but she finally shot to the surface a short time later. I could see someone waving through the view port, so hopefully everyone inside that soda can is okay. I radioed the Vereshchagin and she's on her way to fish them out."
