Still, even if he wouldn’t get the money, Kurt liked to win.
“In fifteen seconds, begin descent to two hundred fifty feet,” Joe said.
Kurt put his hand to a keypad, typed in 2-5-0, and held his finger over the “Enter” button. Either Kurt or Joe could change the depth manually if they wanted, but the computer was more precise.
“Three… two… one… mark.” Kurt hit “Enter,” and they heard the sound of a small pump as it pushed oil from the rear into a forward chamber of the sub. This caused the nose to grow heavier and pitch down. With no need to take on water, to angle dive planes, or to adjust power, the Barracudacontinued at flank speed, descending, and actually accelerating as it dove.
Around them the light began to fade, the color changing from a bright aquamarine to a darker blue. Up above, it was a beautiful sunny day, with high pressure all around.
“How we doing?” Kurt asked.
“Four miles to the outer marker,” Joe said.
“What about the other contestants?”
It was a timed race, the subs having left at ten-minute intervals to keep them apart, but Kurt and Joe had already passed one vessel. Somewhere up ahead they would catch another competitor.
“We could ram them if they get in our way,” Joe said.
“This isn’t NASCAR,” Kurt replied. “I’m thinking that would be some kind of points deduction.” As Kurt kept the Barracudaprecisely online, he heard Joe tapping keys behind him.
“According to the telemetry,” Joe said, “the XP-4 is a half mile ahead. We should see his taillights in about ten minutes.” That sounded good to Kurt. The next depth change was in seven minutes. They would come up to one hundred fifty feet, cruise over a ridge, and race along near the top of an underwater mesa — a flat plain that had once been an underwater lava field.
“Easier and more fun to pass people when they can see you go by,” he said.
Seven minutes later, Kurt put the Barracudainto a climb, they zoomed up over the ridge and leveled off at one hundred fifty feet. A moment later the radio crackled.
“… experiencing elec—…—blems… batteries… system malfunc—…” The garbled low-frequency signal was hard to make out. But it rang alarm bells in Kurt’s mind.
“You get that?”
“I couldn’t make it out,” Joe said. “Someone’s having problems though.” Kurt grew quiet. All the subs had been equipped with a low-frequency radio that, theoretically, could reach floating buoys along the race path and be retransmitted to the referee and safety vessels stationed along the route. But the signal was so weak, Kurt couldn’t tell who was transmitting.
“Did he say electrical problems?”
“I think so,” Joe said.
“Call him out,” Kurt said.
A moment later Joe was on the radio. “Vessel reporting problems. Your transmission garbled. Please repeat.” The seconds ticked by with no response. Kurt’s sense of danger rose. To make the submarines fast, most had been built with somewhat experimental technology. Some even used lithium ion batteries that, in rare circumstances, could catch fire. Others used experimental electrical motors and even hulls of thin polymers.
“Vessel reporting problems,” Joe said again. “This is Barracuda. Please repeat your message. We will relay to the surface.” Up ahead, Kurt saw a trail of bubbles. It had to be the wake of the XP-4. He’d forgotten all about it and was now driving right up its tailpipe. He banked the Barracudato the left and then noticed something odd: the trail of bubbles arced down and to the right. It didn’t make any sense, unless…
“It’s the XP-4,” he said. “It’s got to be.” “Are you sure?”
“Check the GPS.”
Kurt waited while Joe switched screens. “We’re right on top of him.” “But I don’t see him anywhere,” Kurt said.
Joe went right back to the radio. “XP-4, do you read?” Joe said. “Are you reporting trouble?” A brief burst of static came over the radio and then nothing.
“We’ll lose if we turn,” Joe said.
Kurt had considered that. The rules were strict.
“Forget the race,” Kurt said, and he banked the Barracudainto a wide right turn, slowing her pace and manually taking over depth control. Throwing on the Barracuda’s lights, he searched for the trail of bubbles.
“What’s the XP-4 made of?” he asked. Joe knew the other competitors far better than he did.
“She’s stainless steel like us,” Joe said.
“Maybe we could use the magnetometer to help find her. A thousand pounds of steel ought to get us a reading from this distance.” Kurt spotted what he thought was the line of bubbles. He turned to follow the curving, descending trail. Behind him Joe booted up the magnetometer.
“Something’s wrong,” Joe said, fiddling with the controls.
“What’s the problem?”
“See for yourself.”
Joe pressed a switch, and the central screen on Kurt’s display panel changed. The lines of azimuth and magnetic density should have been a relatively clear display, but the various lines were spiking and dropping, and the directional indicator was pivoting like a compass needle just spinning in circles.
“What the heck’s wrong with it?” Kurt mumbled.
“Don’t know.”
The radio buzzed with static again and this time a voice cut through it.
“… continued problems… smoke in cabin… possible electrical fire… shutting down all systems… please—” The transmission ended abruptly, and it chilled Kurt’s blood.
He looked through the curved Plexiglas windshield of the Barracuda, slowing the small submarine even further. As the speed bled off, he pitched the nose over until they were angled almost straight down.
Dropping slowly through the water, he scanned the bottom. At one hundred fifty feet, light from the surface still filters through, but the surrounding color is a pure dark blue, and the visibility is limited to somewhere around fifty feet.
Increasing that visibility were the Barracuda’s lights. Since seawater scatters and absorbs longer wavelengths of light rapidly, Joe had installed special bulbs that burned in a bright yellow-green part of the visible spectrum. The lights helped cut through the gloom, and as the Barracudaapproached the bottom Kurt spotted what looked like a gouge in the sandy sediment.
He turned to follow it.
“There,” Joe said.
Up ahead, a tubular steel shape that looked more like a traditional submarine lay on its side. The designation “XP-4” could be seen, painted in large black letters.
Kurt circled around it until he reached a spot from which the canopy could be viewed. Bubbles were pouring slowly from the tail end of the sub, but the cockpit seemed intact.
He shut the lights off and tried to hover alongside, though the current was making it difficult.
“Signal them.”
As Kurt struggled to keep the Barracudain position, Joe grabbed a penlight, aimed it out the window at the XP-4, and tapped out a message in Morse code.
Kurt could see some movement inside, and then a message came back.
“All… elec… pwr… out,” Joe said, translating.
Kurt felt them drifting again and tapped the thruster.
“They have to have oxygen,” Kurt said, reviewing in his mind the safety rules the event’s organizers had put in place. “Can they pop the canopy?” Joe flashed the light on and off, putting the message through. The response dashed those hopes.
“Canopy… elec… trapped.”
“Who ever heard of making your canopy electric?” Kurt mumbled. Then he looked back at Joe.
“Ours has a manual release,” Joe assured him.
“Just checking.”
Joe smiled. “Can we tow them out?”
“Looks like we’ll have to,” Kurt said. “Use the hook.” Behind him, Joe activated the controls for the grappling system, and a panel on the right wing of the Barracudaopened. A folded metallic apparatus emerged. Once it was locked into place, it unfolded into a long metallic arm with a claw on the end.
Even as the claw extended, Kurt realized they were drifting away from the XP-4.
“Get me closer,” Joe said.
Kurt nudged the thrusters again, and the Barracudaangled toward the rear section of the XP-4 to a point where a handle extended from its hull. On the surface, the XP-4’s mother ship would lock onto this handle with a crane to hoist the sub out of the water. Kurt and Joe would try to do the same down below.
“Maybe this could help our salvage grade,” Joe said.
“Just grab the sub,” Kurt said.
The claw extended and missed. Kurt adjusted their position, and Joe tried again and missed again.
“Something’s wrong,” Joe said.
“Yeah, your aim,” Kurt said.
“Or your driving,” Joe said.
Kurt didn’t want to hear that, but it was true. And yet each time he adjusted for the current, the Barracudaseemed to get pulled off-line again. He glanced outside at the sediment in an attempt to get the best read on the current.
“Ah, Kurt…?” Joe said.
Kurt ignored him. Something definitely waswrong. Unless his eyes had been damaged somehow, the Barracudawas drifting in the opposite direction of the current. And, strangely enough, the XP-4 was moving as well, albeit at a slower rate as she was dragging along the bottom.
“Kurt,” Joe said with more urgency.
“What?”
“Look behind us.”
Kurt turned the sub a few degrees and craned his neck around. The sandy bottom gave way to darkness. They were drifting toward a cliff of sorts. On the charts it appeared as a deep circular depression with a rise in the middle: the caldera of a volcano that had once been active here thousands of years before.
Thoughts of the damaged XP-4 tumbling down the edge of that caldera with two men trapped inside were enough to make Kurt forget about the strange movements of both subs. All he wanted to do was grab the XP-4 and get out of there.
He pressed forward until they were nose to nose with the other sub. Joe stabbed at the small handle with the grappling claw but could not catch it. Sediment began to stir up around them as Kurt goosed the thrusters.
They’d reached the point where the ground had started sloping away.
Whatever was going on, they were being dragged toward the caldera. Kurt used main power, blocking the XP-4, pumping the throttle, in an attempt to hold them back.
The XP-4 began to swing, pivoting against the nose of the Barracuda. It was being pulled past her. The caldera yawned behind them.
“It’s now or never, Joe.”
Joe grunted as he worked the controls. The arm extended, and the claw locked on.
“Got him,” Joe said.
The XP-4 had reached the edge and was tumbling; Kurt had no choice but to let the Barracudafall with it for a moment. If he gunned the throttle, the arm would bend and snap under the load.
They slipped off the edge, drifting backward and out into the dark. Kurt turned the nose of the Barracudaaway from the XP-4. The grappling claw pivoted until it was pointing to the rear, and the two subs fell sideways as Kurt brought the main thruster slowly up to power.
Slowly, the Barracudapulled the XP-4 away from the caldera’s wall and began to level off. Both vessels were still sinking, still being strangely drawn toward the center of the volcano.
The Barracudabegan to accelerate, with the XP-4’s torpedo-shaped body trailing behind them. As long as Kurt towed them and didn’t twist or bend the arm, he was fairly confident it would hold.
“We’re still descending,” Joe said.
Kurt was aware of that but couldn’t explain it.
“Maybe they took on some water,” he guessed. He added more power until the thruster was almost fully on. The descent slowed, and they began to pick up speed, speed they would need to climb.
A shape loomed up ahead, a hundred-foot column of rock that rose up from the center of the caldera like a chimney. If he had to guess, Kurt would have said it was the volcanic plug that cooled and hardened when this particular vent for the earth’s heat had gone dormant. Problem was, it lay directly in their path.
“Should I blow the tanks?” Joe asked.
“No, we’ll lose them,” Kurt said. He went to full power and slowly pulled the nose up. They were approaching the tower of rock awfully fast.
“Come on,” Kurt urged.
It felt as if the tower of rock was drawing them in like a black hole. And with the weight they were towing, they seemed almost incapable of rising at anything more than the slowest of speeds.
“Climb, damn it,” Kurt grunted.
They were heading right into it, like a plane flying into a cliff. All light from the surface was cut off by the shadow of the rock. They were rising but not fast enough. It looked like they were going to hit it head-on.
“Come on,” Kurt said.
“Kurt?” Joe said, his hand over the ballast control.
“Come on, you—”
Suddenly, they saw light again, and at the last second they rose up over the tower. Kurt leveled off, allowing their speed to increase.
“Think we scraped the paint,” Kurt said.
Behind him, Joe breathed a sigh of relief. “Look at the magnetometer,” he said.
Kurt didn’t really hear him.
“It’s pointing dead aft, right at that tower of rock. This is some kind of high-intensity magnetic field,” Joe said.
At any other time, Kurt would have found that interesting, but ahead of him, lit up by the blazing yellow-green lights, he gazed upon a sight he found hard to believe.
The mast of a great ship sprouted from the ocean floor like a single limbless tree. Beyond it lay a smaller fishing vessel, and just to the left of that was what might have once been the hull of a tramp steamer.
“Joe, do you see this?” he asked.
As Joe angled for a better view, Kurt took the Barracudaright over the three vessels. As he did, they spotted several more. Cargo vessels that looked like the old Liberty ships, rusting hulks covered in a thin layer of algae and sediment. All around them, boxy containers lay strewn about as if they’d been dumped over the side of some ship at random.
He saw the wing of a small aircraft, and four or five more unrecognizable objects that appeared to be man-made.
“What is this place?” Kurt wondered aloud.
“It’s like some kind of ship graveyard,” Joe said.
“What are they all doing here?”
Joe shook his head. “I have no idea.” They passed over the wrecks, and the ocean bottom slowly returned to normal, mostly sediment and silt, with plant life and bits of coral here and there.
Wanting to go back but realizing they had a more important rendezvous with the surface, Kurt put the Barracudainto a nose-up climb once again. Slowly, the seafloor began to recede.
Then, just before their lights lost contact, Kurt saw something else: the fuselage of a large aircraft, half buried in the silt. Its long, narrow cabin swooped back in graceful flowing lines until it ended in a distinctive triple tail.
Kurt knew that plane. When he was younger, he and his father had built a model of it, which Kurt and a friend had blown to pieces with fireworks they’d found.
The aircraft with the sweeping lines and the triple tail was unique. It was the beautiful Lockheed Constellation.
