PROLOGUE

      “What was that?” the pilot of the 747 demanded, leaning forward in his seat.

      For a split second the man could have sworn that he saw a flock of birds tumbling out of the night sky alongside the speeding jumbo jet. In an instant they were gone, left far behind. But the image remained in his mind. Hundreds of falling bodies, wings spread wide.

      “Trouble?” the copilot asked, looking up from the clipboard in his hands. He had been busy working on the fuel consumption figures.

      “Not sure,” the pilot replied, looking over to check the radar. They were flying low enough for birds to reach the 747, only ten thousand feet, but the scope was clean, and the flight plan showed that no other planes should be near them for a hundred miles. Aside from the flight of F-18 fighters flying escort, the nighttime sky was clear with only a few sporadic clouds on the horizon and the infinite heavens above. Then what the hell knocked down a flight of birds? he wondered.

      There was no moon. Below the speeding plane, the world twinkled with the city lights of the villages and towns of Ohio. The digital clock blinked into midnight, and the pilot saw the map on the plasma screen monitor shift position slightly. Okay, make that Pennsylvania.

      Briefly the pilot considered contacting the Secret Service agents in the rear of the plane, but decided against disturbing the men. What could he say? Some dead birds fell out of the sky? How could that possibly be a threat to the armored 747 and its august passengers?

      Ever since 1995, there were three Boeing jumbo jets that bore the designation VC-25. The planes only assumed the call sign Air Force One when the President was on board. The three planes were in constant service, sometimes flying empty across the continent, to make it all but impossible for an enemy of America to precisely track the whereabouts of the nation’s political leader. Thankfully, the current flight from Los Angeles to Boston was a milk run. The jumbo jet was almost empty, bearing only a couple of Homeland Security agents, a civil servant, an elderly scientist and a dozen Secret Service agents. Nothing to attract a terrorist attack.

      Adjusting the trim slightly, the pilot couldn’t shake the feeling of dread. Those birds had only been in sight for a moment, yet he felt certain that they had been dead and not merely knocked unconscious from the wash of the turbojets. A former combat pilot in the first Gulf War, the man had learned to trust his instincts. And there was definitely something odd about a hundred birds tumbling from the nighttime sky.

      “What’s wrong, Chief, see a UFO?” The navigator chuckled as he poured himself a cup of coffee from an insulated carafe.

      “Maybe you’ve finally burned out your brain on caffeine,” the pilot suggested with a wane smile.

      The navigator laughed. “With Jamaican Blue? Not possible.”

      “Coffee that sells for more than cocaine.” The copilot sadly shook his head, placing aside the clipboard. “Waste of money, if you ask me.”

      “If I gave you a sip, you’d never say that again,” the navigator said, holding the cup in both hands to savor the delicious aroma. Then he took a taste, the thick rich Jamaican coffee filling his mouth with scalding flavor.

      “Really? Okay, so pour me a cup.”

      “Ha! I said a sip, besides…” Pausing in the middle of the sentence, the navigator stopped talking and slumped in his seat. The hot coffee splashed across the console, seeping into the banks of controls.

      “Bob, are you okay?” the copilot asked, looking over a shoulder. Then he shuddered and went limp, easing down in his seat as both hands dropped to his sides. The clipboard on his lap slipped away to clatter on the deck.

      Instantly alert, the pilot flipped the alarm switch and the autopilot at the same time. One odd thing could be ignored, but two always spelled trouble. First dead birds falling from the sky, now this. Was the plane being attacked?

      “Report,” said a brusque voice over the intercom.

      Reaching for the hand mike, the pilot suddenly felt a tingling warmth engulf his body, then an infinite blackness swelled to fill the universe.

      “I smell Jamaican Blue!” a flight attendant called out jokingly, opening the hatch to the flight deck. Just for a split second the man saw the still bodies of the crew before he also crumpled into a heap, dropping a tray of sandwiches.

      In the main galley, the other attendants turned at the noise, then reeled and toppled over, one of them splashing hot soup everywhere.

      From their seats, the Secret Service agents looked up at the commotion and started to rise when they also paused, then limply collapsed back into their seats.

      The door to the private washroom swung open and the director of special projects for the Department of Defense stepped into the aisle. The man gasped at the sight of everybody sprawled in their seats, and felt the hairs at his nape rise in warning. Something was horribly wrong.

      “Get Himar off the plane!” the man shouted, lurching toward a rack of emergency parachutes. But that was when a wave of warmth filled his body and the director tumbled onto the carpeting.

      At the aft of the 747, Himar glanced up at the sound of his name, then the scientist slumped in his seat, both hands motionless on the keyboard, the plasma screen filling with lines of total gibberish.

      Unstoppable death swept through the 747, touching everybody on board. In moments, the jumbo jet was a flying coffin, totally devoid of life. The only sounds were the drip of the spilled coffee, the hushed whisper of the air vents and the muted thunder of the powerful engines.

      Staying a loose combat formation, the wing of jet fighters kept a careful watch on VC-25. As per standing regulations, the Air Force pilots stayed in constant communication with SAC headquarters, and through them, the situation room of the White House. But there was nothing to report. The flight was on course, and on schedule. Everything was normal.

      Rigidly maintaining the last heading, the 747 continued toward distant Boston, guided solely by the autopilot…
