It was oven hot, and it was Sunday. In the air traffic tower, the control operator at Brady Air Force Base lit a cigarette from a still glowing butt, propped his stocking feet on top of a portable air conditioner and waited for something to happen.

He was totally bored, and for good reason. Air traffic was slow on Sundays. In fact, it was nearly nonexistent Military pilots and their aircraft rarely flew on that day in the Mediterranean Theatre of Operations, particularly since no international political trouble was brewing at the moment. Occasionally a plane might set down or take off, but it was usually just a quick refueling stop for some VIP who was in a hurry to get to a conference somewhere inEuropeor Africa.

The control operator scanned the large flight schedule blackboard for the tenth time since he came on duty. There were no departures, and the only estimated time of arrival was at 1630, almost five hours away.

He was young — in his early twenties — and strikingly refuted the myth that fair-haired people cannot tan well; wherever skin showed, it looked like dark walnut laced with strands of platinum blond hair. The four stripes on his sleeve denoted the rank of a Staff Sergeant, and although the temperature was touching ninety-eight degrees, the armpits of his khaki uniform displayed no damp sweat stains. The collar on his shirt was open and missing a tie; a custom normally allowed at Air Force facilities located in warm atmospheres.

He Leaned forward and adjusted the louvers on the air conditioner so that the cool air ran up his legs.

The new position seemed to satisfy him. and he smiled at the refreshing tingle. Then, clasping his hands behind his head, he relaxed backward, staring at the metal ceiling.

The ever-present thought of Minneapolisand the girls parading Nicollet Avenue crossed his mind. He counted again the fifty-four days left to endure before he was rotated back to the States. When each day came it was ceremoniously marked off in a small black notebook he carried in his breast pocket.

Yawning for perhaps the twentieth time, he picked up a pair of binoculars that were sitting on the window ledge, and surveyed the parked aircraft that rested on the dark asphalt runway stretching beneath the elevated control tower.

The runway lay on theisland of Thasosin the northern part of the Aegean Sea. The island was separated from the Greek Macedonia mainland by sixteen miles of water. appropriately called the Thasos Strait The Thasos land mass consisted of one hundred and seventy square miles of rock, timber and remnants from classical history dating back to One Thousand B.C.

Brady Field, as generally termed by the base personnel, was constructed under a treaty between the United Statesand the Greek government in the late nineteen sixties. Except for ten F-105 Starfire Jets, the only other permanently based aircraft were two monstrous C-133 Cargomaster transports that sat like a pair of fat silver whales, glistening in the blazing Aegean sun.

The sergeant pointed the binoculars at the dormant aircraft and searched for signs of life. The field was empty. Most of the men were either in the nearby town of Panaghia drinking beer, sunbathing on the beach or napping in the air-Cooled barracks. Only a solitary MP guarding the main gate, and the constant rotation of the radar antennae atop its cement bunker offered any form of human presence. He slowly raised the lenses and peered over the azure sea. It was a bright, cloudless day, and he could easily recognize details on the distant Greek mainland. The glasses swung east and gathered in the horizon line where deep blue water met light blue sky. Through the shimmering haze of heat waves the white speck of a ship resting at anchor came into view. He squinted and adjusted the focus knob to clarify the ship’s name on the bow. He could just barely make out the tiny black words: First Attempt.

That's a dumb name. he thought. The significance escaped him. Other markings also darkened the ship’s hull. In long, heavy, black lines across the center of the bull were the vertical letters NUMA which he knew stood for the National Underwater Marine Agency.

A huge crooked crane stood on the stern of the ship and hung over the water, lifting a round ball-like object from the depths. The sergeant could see men laboring about the crane, and he felt inwardly glad that civilians had to work on a Sunday too. Suddenly his visual exploration was cut short by a robot-like voice over the intercom.

“Hello, Control Tower, this is Radar… Over!”

The sergeant laid down the binoculars and flicked a microphone switch. “This is the Control Tower, Radar. What’s up?”

“I’ve got a contact about ten miles to the west.”

“Ten miles west?” boomed the sergeant. “That’s inland over the island. Your contact is practically on top of us.” He turned and looked again at the big lettered blackboard, reassuring himself that no scheduled flights were due. “Next time, let me know sooner?”

“Beats me where it came from,” droned the voice from the radar bunker. “Nothing has shown on the scope in any direction under one hundred miles in the last six hours.”

“Well either stay awake down there or get your-damn equipment checked,” snapped the sergeant. He released the mike button and grabbed the binoculars.

Then he stood up and peered to the west.

It was there… a tiny dark dot, flying low over the hills at tree top level. It came slow; no more than ninety miles an hour. For a few moments it seemed to hang suspended over the ground, and then, almost all at once, It began to take on shape. The outlines of the wings and fuselage drew into sharp focus through the binoculars. It was so dear as to be unmistakable. The sergeant gaped in astonishment as the rattley-bang engine sound of an old single seat, biwing airplane complete with rigid, spoked wheel landing gear, tore the arid island air. Except for the protruding in-line cylinder head, the fuselage followed a streamlined shape that tapered to straight skies at the open cockpit The great wooden propeller beat the air like an old windmill, pulling the ancient craft over the landscape at a tortoise-like air speed. The fabric covered wings wavered in the wind and showed the early characteristic scalloped trailing edge. From the spinner enclosing the propeller hub to the rear tips of the elevators, the entire machine was painted a bright and flamboyant yellow. The sergeant lowered the glasses just as the plane displaying the familiar black Maltese Cross markings of World War I Germany, flashed by the control tower.

In another circumstance the sergeant would have probably dropped to the floor if an airplane buzzed the control tower at no more than five feet. But his amazement at seeing a very real ghost from the dim skies of the Western Front was too much for his senses to grasp, and he stood stock still. As the plane passed, the pilot brazenly waved from his cockpit. He was so close that the sergeant could see the features of his face under the faded leather helmet and goggles. The spectre from the past was grinning and patting the butts of the twin machine guns, mounted on the cowling.

Was this some sort of colossal joke? Is the pilot a nutty Greek with a circus? Where did he come from?

The sergeant’s brain spun with questions but no answers. Suddenly he became aware of twin, blinking spots of light, emitting behind the propeller of the plane. Then the glass of the control tower windows shattered and disappeared around him.

A moment in time stopped and war came to Brady Field. The pilot of the World War I fighter dipped around the control tower and strafed the sleek modern jets parked lazily on the runway. One by one the F-105 Starfires were raked and slashed by ancient eight millimeter bullets that tore into their thin aluminum skin. Three of them burst into flames as their full tanks of jet fuel ignited. They burned fiercely, melting the soft asphalt into smoking puddles of tar. Again and again, the bright yellow flying antique soared over the field, spitting a leaden stream of destruction. One of the C-133 Cargomasters went next.
