They would be unable to go into s.p.a.ce, but they would be very fast, and capable of carrying large tanks of the gas-producing chemicals.
It was near midnight, Venerian time, when they turned in. The following day they planned to start for the Kaxorian construction camp. They had learned from Tonlos that there were but five of the giant planes completed now, but there were fifteen more under construction, to make up the fleet of twenty that was to attack Earth. These fifteen others would be ready in a week--or less. When they were ready, the _Solarite_ would stand small chance. They must capture one of the giants and learn its secrets, and then, if possible, with the weapons and knowledge of two worlds, defeat them. A large order!
Their opportunity came sooner than they had hoped for--or wanted. It was about three o"clock in the morning when the telephone warning hummed loudly through the ship. Arcot answered.
Far to the east and south of them the line of scout planes that patrolled all the borders of Lanor had been broken. Instantaneously, it seemed, out of the dark, its lights obscured, the mighty Kaxorian craft had come, striking a tiny scout plane head on, destroying it utterly before the scout had a chance to turn from the path of the t.i.tanic ship.
But even as the plane spun downward, the pilot had managed to release a magnesium flare, a blindingly brilliant light that floated down on a parachute, and in the blaze of the white light it gave off, the other scouts at a few miles distance had seen the mighty bulk of the Kaxorian plane. At once they had dropped to the ground and then, by telephone lines, had sent their report to far off Sonor.
In moments the interior of the _Solarite_ became a scene of swift purposeful activity. All day the Terrestrians had been able to do so little in preparation for the conflict they knew must come, the battle for two worlds. They had wanted action, but they had no weapons except their invisibility and the atomic hydrogen. It would not sink a plane.
It would only break open its armor, and they hoped, paralyze its crew.
And on this alone they must pin their hopes.
VI
Arcot lifted the _Solarite_ at once high into the air, and started toward the point on the border, where the plane had been seen crossing.
In a short time Wade relieved him at the controls while he dressed.
They had been flying on in silence for about an hour, when suddenly Wade made out in the distance the great bulk of the plane, against the dull gray of the clouds, a mile or so above them. It seemed some monstrous black bat flying there against the sky, but down to the sensitive microphone on the side of the _Solarite_ came the drone of the hundred mighty propellers as the great plane forged swiftly along.
Just how rapidly these giants moved, Arcot had not appreciated until he attempted to overtake this one. It was going over a mile a second now--a speed that demanded only that it move its own length in about five-eights of a second! It made this tremendous speed by streamlining and through sheer power.
The _Solarite_ hovered high above the dark ship at length, the roar of the terrific air blast from its propellers below coming up to them as a mighty wave of sound that made their own craft tremble! The hundred gigantic propellers roaring below, however, would distribute their gas perfectly.
"We"re going invisible," Arcot exclaimed. "Look out!" There was a click as the switch shut, and the _Solarite_ was as transparent as the air above it. Arcot drove his ship swiftly, above and ahead of the mighty colossus, then released the gas. There was a low hiss from the power room, barely detectable despite the vacuum that shut them off from the roar of the Kaxorian plane. The microphone had long since been disconnected. Out of the gas vent streamed a cloud of purplish gas, becoming faintly visible as it left the influence of the invisibility apparatus, but only to those who knew where to look for it. The men in that mighty plane could not see it as their machine bore down into the little cloud of gas.
Tensely the Terrestrians waited. Moments--and the gigantic plane wobbled! There was a sudden swerve that ended in a nose dive, straight toward Venus seven miles below.
That the ship should crash into the ground below was not at all Arcot"s plan, and he was greatly relieved when it flattened its dive and started to climb, its incalculable ma.s.s rapidly absorbing its kinetic energy.
Down from its seven mile height it glided, controlling itself perfectly as Arcot released the last of the first four containers of the liquid gas makers, putting to sleep the last man on the ship below.
In a long glide that carried it over many miles, the great ship descended. It had sunk far, and gone smoothly, but now there loomed ahead of it a range of low hills! It would certainly crash into the rocky cliffs ahead! Nearer and nearer drew the barrier while Arcot and the others watched with rigid attention. It might skim above those low hills at that--just barely escaping.... The watchers cringed as head on, at nearly two thousand miles an hour, the machine crashed into the rocks. Arcot had snapped the loud speaker into the circuit once more, and now as they looked at the sudden crash below, there thundered up to them mighty waves of sound!
The giant plane had struck about twenty feet from the top of a nearly perpendicular cliff. The terrific crash was felt by seismographs in Sonor nearly two thousand miles away! The mighty armored hull plowed into the rocks like some gigantic meteor, the hundreds of thousands of tons crushing the rocky precipice, grinding it to powder, and shaking the entire hill. The cliff seemed to buckle and crack. In moments the plane had been brought to rest, but it had plowed through twenty feet of rock for nearly an eighth of a mile. For an instant it hung motionless, perched perilously in the air, its tail jutting out over the little valley, then slowly, majestically it sank, to strike with a reverberating crash that shattered the heavy armor plate!
For another instant the great motors continued turning, the roar of the propellers like some throbbing background to the rending crashes as the t.i.tanic wreck came to rest. Suddenly, with a series of roaring explosions, the bank of motors in the left wing blew up with awful force. There was a flash of indescribable brilliance that momentarily blinded the watching Terrestrians; then there came to the microphone such waves of sound as it could not reproduce. From the rock on which rested the fused ma.s.s of metal that they knew had been the wing, rose a great cloud of dust. Still the motors on the other side of the ship continued roaring and the giant propellers turned. As the blast of air blew the dust away, the Terrestrians stared in unbounded amazement. Up from the gaping, broken wing lanced a mighty beam of light of such dazzling intensity that Arcot swiftly restored them to visibility that they might shut it out. There was a terrific hissing, crackling roar.
The plane seemed to wobble as it lay there, seemingly recoiling from that flaming column. Where it touched the cliff there was intense incandescence that made the rock glow white hot, then flow down in a sluggish rivulet of molten lava! For five minutes longer this terrific spectacle lasted, while Arcot withdrew the _Solarite_ to a safer distance.
The fifty motors of the remaining wing seemed slowing down now--then suddenly there was such a crash and towering flash of light as no human being had ever seen before! Up--up into the very clouds it shot its mighty flame, a blazing column of light that seemed to reach out into s.p.a.ce. The _Solarite_ was hurled back end over end, tumbling, falling.
Even the heavy gyroscopes could not hold it for an instant, but quickly the straining motors brought them to rest in air that whirled and whined about them. They were more than twenty miles from the scene of the explosion, but even at that distance they could see the glow of the incandescent rock. Slowly, cautiously they maneuvered the _Solarite_ back to the spot, and looked down on a sea of seething lava!
Morey broke the awed silence. "Lord--what power that thing carries! No wonder they could support it in the air! But--how can they control such power? What t.i.tanic forces!"
Slowly Arcot sent the _Solarite_ away into the night--into the kindly darkness once more. His voice when he spoke at last was oddly restrained.
"I wonder what those forces were--they are greater than any man has ever before seen! An entire hill fused to molten, incandescent rock, not to mention the tons and tons of metal that made up that ship.
"And such awful forces as these are to be released on our Earth!" For an interminable period they sat silent as the panorama of hills glided by at a slow two-hundred miles an hour. Abruptly Arcot exclaimed, "We _must_ capture a ship. We"ll try again--we"ll either destroy or capture it--and either way we"re ahead!"
Aimlessly they continued their leisurely course across a vast plain.
There were no great mountains on Venus, for this world had known no such violent upheaval as the making of a moon. The men were lost in thought, each intent on his own ideas. At length Wade stood up, and walked slowly back to the power room.
Suddenly the men in the control room heard his call:
"Arcot--quick--the microphone--and rise a mile!"
The _Solarite_ gave a violent lurch as it shot vertically aloft at tremendous acceleration. Arcot reached over swiftly and snapped the switch of the microphone. There burst in upon them the familiar roaring drone of a hundred huge propellers. No slightest hum of motor, only the vast whining roar of the mighty props.
"Another one! They must have been following the first by a few minutes.
We"ll get this one!" Arcot worked swiftly at his switches. "Wade--strap yourself in the seat where you are--don"t take time to come up here."
They followed the same plan which had worked so well before. Suddenly invisible, the _Solarite_ flashed ahead of the great plane. The t.i.tanic wave of rushing sound engulfed them--then again came the little hiss of the gas. Now there were no hills in sight, as far as the eye could see.
In the dim light that seemed always to filter through these gray clouds they could see the distant, level horizon.
Several dragging minutes pa.s.sed before there was any evident effect; the men from Earth were waiting for that great ship to waver, to wobble from its course. Suddenly Arcot gave a cry of surprise. Startled amazement was written all over his face, as his companions turned in wonderment to see that he was partially visible! The _Solarite_, too, had become a misty ghost ship about them; they were becoming visible! Then in an instant it was gone--and they saw that the huge black bulk behind them was wavering, turning; the thunderous roar of the propellers fell to a whistling whine; the ship was losing speed! It dipped, and shot down a bit--gained speed, then step by step it glided down--down--down to the surface below. The engines were idling now, the plane running more and more slowly.
They were near the ground now--and the watchers scarcely breathed. Would this ship, too, crash? It glided to within a half mile of the plain--then it dipped once more, and Arcot breathed his relief as it made a perfect landing, the long series of rollers on the base of the gigantic hull absorbing the shock of the landing. There were small streams in the way--a tree or two, but these were obstacles unnoticed by the gargantuan machine. Its mighty propellers still idling slowly, the huge plane rolled to a standstill.
Swooping down, the _Solarite_ landed beside it, to be lost in the vast shadows of the mighty metal walls.
Arcot had left a small radio receiver with Tonlos in Sonor before he started on this trip, and had given him directions on how to tune in on the _Solarite_. Now he sent a message to him, telling that the plane had been brought down, and asking that a squadron of planes be sent at once.
Wade and Arcot were elected to make the first inspection of the Kaxorian plane, and clad in their cooling suits, they stepped from the _Solarite_, each carrying, for emergency use, a small hand torch, burning atomic hydrogen, capable of melting its way through even the heavy armor of the great plane.
As they stood beside it, looking up at the gigantic wall of metal that rose sheer beside them hundreds of feet straight up, it seemed impossible that this mighty thing could fly, that it could be propelled through the air. In awed silence they gazed at its vast bulk.
Then, like pygmies beside some mighty prehistoric monster, they made their way along its side, seeking a door. Suddenly Wade stopped short and exclaimed: "Arcot, this is senseless--we can"t do this! The machine is so big that it"ll take us half an hour of steady walking to go around it. We"ll have to use the _Solarite_ to find an entrance!"
It was well that they followed Wade"s plan, for the only entrance, as they later learned, was from the top. There, on the back of the giant, the _Solarite_ landed--its great weight having no slightest effect on the Kaxorian craft. They found a trap-door leading down inside. However, the apparatus for opening it was evidently within the hull, so they had to burn a hole in the door before they could enter.
What a sight there was for these men of Earth. The low rumble of the idling engines was barely audible as they descended the long ladder.
There was no resemblance whatever to the interior of a flying machine; rather, it suggested some great power house, where the energies of half a nation were generated. They entered directly into a vast hall that extended for a quarter of a mile back through the great hull, and completely across the fuselage. To the extreme nose it ran, and throughout there were scattered little globes that gave off an intense white light, illuminating all of the interior. Translucent bull"s-eyes obscured the few windows.
All about, among the machines, lay Venerians. Dead they seemed, the illusion intensified by their strangely blue complexions. The two Terrestrians knew, however, that they could readily be restored to life.
The great machines they had been operating were humming softly, almost inaudibly. There were two long rows of them, extending to the end of the great hall. They suggested mighty generators twenty feet high. From their tops projected two-feet-thick cylinders of solid fused quartz.
From these extended other rods of fused quartz, rods that led down through the floor; but these were less bulky, scarcely over eight inches thick.
The huge generator-like machines were disc-shaped. From these, too, a quartz rod ran down through the floor. The machines on the further row were in some way different; those in the front half of the row had the tubes leading to the floor below, but had no tubes jutting into the ceiling. Instead, there were many slender rods connected with a vast switchboard that covered all of one side of the great room. But everywhere were the great quartz rods, suggesting some complicated water system. Most of them were painted black, though the main rods leading from the roof above were as clear as crystal.
Arcot and Wade looked at these gigantic machines in hushed awe. They seemed impossibly huge; it was inconceivable that all this was but the power room of an airplane!
Without speaking, they descended to the level below, using a quite earthly appearing escalator. Despite the motionless figures everywhere, they felt no fear of their encountering resistance. They knew the effectiveness of Wade"s anesthetic.
