Chapter 8

The Solarite sped swiftly toward the southwest. The sky slowly grew lighter as the miles flashed beneath them. They were catching up with the sun. As they saw the rolling ocean beneath them give way to low plains, they realized they were over Kaxorian land. The Solarite was flying very high, and as they showed no lights, and were not using the invisibility apparatus, they were practically undetectable. Suddenly they saw the lights of a mighty city looming far off to the east.

“It’s Kanor. Pass well to the west of it. That’s their capital. We’re on course.” Arcot spoke from his position at the projector, telling Wade the directions to follow on his course to the berth of the giant planes.

The city dropped far behind them in moments, followed by another, and another. At length, veering southward into the dusk, they entered a region of low hills, age-old folds in the crust of the planet, rounded by untold millennia of torrential rains.

“Easy, Wade. We are near now.” Mile after mile they flashed ahead at about a thousand miles an hour--then suddenly they saw far off to the east a vast glow that reached into the sky, painting itself on the eternal clouds miles above.

“There it is, Wade. Go high, and take it easy!”

Swiftly the Solarite climbed, hovering at last on the very rim of the cloud blanket, an invisible mote in a sea of gray mist. Below them they saw a tremendous field carved, it seemed, out of the ancient hills. From this height all sense of proportion was lost. It seemed but an ordinary field, with eighteen ordinary airplanes resting on it. One of these now was moving, and in a moment it rose into the air! But there seemed to be no men on all the great field. They were invisibly small from this height.

Abruptly Arcot gave a great shout. “That’s their surprise! They’re ready far ahead of the time we expected! If all that armada gets in the air, we’re done! Down, Wade, to within a few hundred feet of the ground, and close to the field!”

The Solarite flashed down in a power dive--down with a sickening lurch. A sudden tremendous weight seemed to crush them as the ship was brought out of the dive not more than two hundred feet from the ground. Close to blacking out, Wade nevertheless shot it in as close to the field as he dared. Anxiously he called to Arcot, who answered with a brief “Okay!” The planes loomed gigantic now, their true proportions showing clearly against the brilliant light of the field. A tremendous wave of sound burst from the loudspeaker as the planes rolled across the ground to leap gracefully into the air--half a million tons of metal!

From the Solarite there darted a pale beam of ghostly light, faintly gray, tinged with red and green--the ionized air of the beam. It moved in a swift half circle. In an instant the whirr of the hundreds, thousands of giant propellers was drowned in a terrific roar of air. Great snowflakes fell from the air before them; it was white with the solidified water vapor. Then came a titanic roar and the planet itself seemed to shake! A crash, a snapping and rending as a mighty fountain of soil and rock cascaded skyward, and with it, twisting, turning, hurled in a dozen directions at once, twelve titanic ships reeled drunkenly into the air!

For a barely perceptible interval there was an oppressive silence as the ray was shut off. Then a bedlam of deafening sound burst forth anew, a mighty deluge of unbearable noise as the millions of tons of pulverized rock, humus and metal fell back. Some of it had ascended for miles; it settled amid a howling blizzard--snow that melted as it touched the madly churned airfield.

High above there were ten planes flying about uncertainly. Suddenly one of these turned, heading for the ground far below, its wings screaming their protest as the motors roared, ever faster, with the gravity of the planet aiding them. There was a rending, crackling crash as the wings suddenly bent back along the sides. An instant later the fuselage tore free, rocketing downward; the wings followed more slowly--twisting, turning, dipping in mile-long swoops.

The Solarite shot away from the spot at maximum speed--away and up, with a force that nailed the occupants to the floor. Before they could turn, behind them flared a mighty gout of light that struck to the very clouds above, and all the landscape, for miles about, was visible in the glare of the released energy.

As they turned, they saw on the plain, below a tremendous crater, in its center a spot that glowed white and bubbled like the top of a huge cauldron.

Nine great planes were circling in the air; then in an instant they were gone, invisible. As swiftly the Solarite darted away with a speed that defied the aim of any machine.

High above the planes they went, for with his radar Arcot could trace them. They were circling, searching for the Solarite.

The tiny machine was invisible in the darkness, but its invisibility was not revealed by the Kaxorian’s radio detectors. In the momentary lull, Fuller asked a question.

“Wade, how is it that those ships can be invisible when they are driven by light, and have the light stored in them? They’re perfectly transparent. Why can’t we see the light?”

“They are storing the light. It’s bound--it can’t escape. You can’t see light unless it literally hits you in the eye. Their stored light can’t reach you, for it is held by its own attraction and by the special field of the big generators.”

They seemed to be above one of the Kaxorian planes now. Arcot caught the roar of the invisible propellers.

“To the left, Wade--faster--hold it--left--ah!” Arcot pushed a button.

Down from the Solarite there dropped a little canister, one of the bombs that Arcot had prepared the night before. To hit an invisible target is ordinarily difficult, but when that target is far larger than the proverbial side of a barn, it is not very difficult, at that. But now Arcot’s companions watched for the crash of the explosion, the flash of light. What sort of bomb was it that Arcot hoped would penetrate that tremendous armor?

Suddenly they saw a great spot of light, a spot that spread with startling rapidity, a patch of light that ran, and moved. It flew through the air at terrific speed. It was a pallid light, green and wan and ghostly, that seemed to flow and ebb.

For an instant Morey and the others stared in utter surprise. Then suddenly Morey burst out laughing.

“Ho--you win, Arcot. That was one they didn’t think of, I’ll bet! Luminous paint--and by the hundred gallon! Radium paint, I suppose, and no man has ever found how to stop the glow of radium. That plane sticks out like a sore thumb!”

Indeed, the great luminous splotch made the gigantic plane clearly evident against the gray clouds. Visible or not, that plane was marked.

Quickly Arcot tried to maneuver the Solarite over another of the great ships, for now the danger was only from those he could not see. Suddenly he had an idea.

“Morey--go back to the power room and change the adjustment on the meteorite avoider to half a mile!” At once Morey understood his plan, and hastened to put it into effect.

The illuminated plane was diving, twisting wildly now. The Solarite flashed toward it with sickening speed, then suddenly the gigantic bulk of the plane loomed off to the right of the tiny ship, the great metal hull, visible now, rising in awesome might. They were too near; they shot away to a greater distance--then again that ghostly beam reached out--and for just a fraction of a second it touched the giant plane.
