Hightower did not reply.
Above him he heard a shell hit the yacht, a two-stage explosion, the first being the warhead and the second, undoubtedly, the fuel tanks. A shock wave buffeted the bottom of the sub.
Gentry could wait no more. His hands reached out in front of him, his right index finger found a button, an arbitrary button, as there were dozens, and he could not even see what color they were much less any writing on them.
Fuck it. He pressed down.
Nothing.
His ears popped again, and a sustained pressure entered his head. He had no idea how deep the water was here, but he neither wanted to keep dropping nor hit the bottom, especially canopy first.
He reached for the next button. Pushed it. Then a third. Then a fourth. He wondered if he was releasing fuel or opening a cargo door or triggering a self-destruction sequence.
Court did not know the first goddamned thing about submarines.
He pressed a fifth button, and immediately warm infrared lighting illuminated the cabin.
His head was killing him, and nausea ripped through his body from his intestines to the back of his neck.
With the new light he quickly scanned dozens of choices, looking for anything to turn on. His finger stopped at a button labeled HUD, and he pressed it without hesitation. The laser head-up display came online, projecting all sorts of data on the windscreen in front of him. Speed and Current Depth increased by the second, an artificial horizon turned slowly clockwise, and a compass heading revolved steadily around the dial.
He wanted situational awareness, and he got it. Now, after the onboard computer told him that he was cork-screwing down to his death, he realized that he really didn't want that info after all.
The pain in his head worsened. He vomited water and bile; some of it spewed through his nose and followed gravity's path, running into his eyes. He smeared away the burn with his sweaty arm, put his hand on the joystick on his right, and tried to right the craft, but it had no effect whatsoever. He pushed the lever that he took for a throttle with his left hand. Again, nothing doing. He stomped his bare left and right feet down, kicking out for rudder pedals that were not there.
The submarine passed sixty feet.
Court fought another wave of nausea and a further increase in panic.
Then he stopped playing with the controls, brought his hands into his lap.
"Zack. You awake?" Court's voice was calm now, no sign of panic or threat to the other man in the doomed submarine.
"Yeah. Just enjoying the ride, bro." Zack's voice was incredibly weak. He'd likely be dead soon, Court realized, no matter what happened to Court. Still, Gentry knew Zack well. He was not as calm as he pretended to be.
Zack Hightower didn't want to die, either.
"I can't make this thing work." Gentry pulled his Glock-19 and held it up in the red light for his rear passenger to see. "But I can make this thing work."
"Really? You're threatening to shoot me? That's all you got, dude? Pretty fucking lame."
Court ignored him. He said, "I've trained without oxygen at depths of one hundred thirty feet. If I blow this hatch in the next minute, flood the sub, and make it to the surface, I figure I can find some floating debris from the yacht to grab on to. With a little luck I should make it back to shore by nightfall."
"And then what?"
"I make it out of the Sudan."
"Right. That's gonna happen."
Court paused. Then said, "I'm the goddamned Gray Man, remember? I'll get it done."
All quiet in the rear seat now.
"But that's one ride I can't take you along on. You understand, don't you, bro?" He mimicked Sierra One.
Again, Zack did not respond. Court took that as a good sign. Hightower was never at a loss for words.
"So I'll live, and you'll die. Which means you fucked up. If you would have helped me with the sub, we both could have made it, meaning you could have lived to kill me another day. Ultimate mission success by temporary delay of mission resolution. Even Denny Carmichael would agree that that is a valid strategy for a good soldier like you to take. You just aren't smart enough to know a good deal when you see it."
Still nothing from behind.
"I'm sure there's a better way to pop this hatch, but the only control I know how to work in this goddamned tub is the trigger of this gun. Wish I could leave the Glock behind for you to shoot yourself before you drown, but it may come in handy onshore."
Zack remained silent. Court hoped he was thinking and hadn't just fallen asleep.
Gentry's head was killing him. His sinuses felt like they would burst open any second with the pressure and the acidic puke in his nose.
"Passing one hundred ten feet." Court began filling his lungs with air. A rapid deep breathing to increase lung capacity. In between breaths he said, "It was a pleasure serving under you most of the time, Zack. I'll send a letter to Langley and tell them you went down with the ship." A few more deep breaths.
Court pushed the barrel of the gun to the Plexiglas's canopy, ducked down away from it.
Zack coughed weakly.
Fuck, thought Court. He's not going for it.
"See ya," Gentry said, stalling an instant more, and then he moved his finger to the trigger and sucked in a full, deep breath of the cabin air.
Here we go.
"Down by your right knee. Dial that says BAL. Turn it all the way to the left to neutralize the ballast. Next to that is a square button that says PROCON. That's propulsion control. Push it now." Zack's voice was weak, but the words sure as hell came out fast.
Gentry lowered the gun, found the dial, and turned it, then found the button and pushed it. Immediately a loud metallic noise filled his aching head. A 2-D computer rendering of the submarine appeared on the HUD. It started as a cigar-shaped image, but when the metal noise stopped, the image had wings and tail fins and looked like a single-engine fighter plane.
"Give it some thrust. Just a touch."
Court tipped the throttle, and he felt a slight engine rumble and sensed gentle forward movement. A HUD reading that had been zero slowly climbed from 5 percent to 10 percent to 20 percent as he pushed the throttle a bit more.
"Now, use the joystick to level her out. It's fly-by-wire. Pitch, yaw, roll, all controlled by the joystick. Kind of like an airplane." Zack coughed. "You crashed a plane once, didn't you?"
"Crash-landed," Court clarified. He'd gone from near post-panicked resignation of his imminent death to near jubilant euphoria at his high prospects for survival, all in the last thirty seconds.
"That was in Kiev, wasn't it?"
"Tanzania, Zack. You were there."
"But again, in Kiev? You crashed there, too, didn't you?"
"No comment."
Quickly he had the descent under control, and then the machine leveled out. A few seconds more, and he had the compass heading pointing due east.
"Headlights," instructed Zack from behind.
"Where?"
"Have you ever been in a car, dumb-ass? Same place."
Court reached to the left in front of him and, yes, the light switch felt just like it did in most wheeled vehicles he'd driven.
He flipped it on.
And shouted in shock. "Oh shit!"
The sub moved quickly along the sandy ocean floor, which was not more than ten feet below.
Court began hyperventilating slightly. He pulled back on the joystick and pushed the throttle forward to 40 percent.
"Okay. Now, a four-position dial on your left, about eleven o'clock."
With the dim red lights it was hard to find, but Court got his fingers around it.
"Turn it all the way. Oxygen scrubbers. We're breathing each other's carbon dioxide at the moment. This will clean the air."
"Roger that."
After Zack's tired voice instructed Court through turning on the O2 system and activating the sub's laser collision avoidance feelers, Court piloted the sub to the east for another minute, getting the feel of the craft. Once confident he had the hang of it, he called back to Hightower again, "How am I doing?"
