The Barracuda began 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 Barracuda right 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 Barracuda into 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.
