On closer inspection, the watchers saw what seemed to be a swarm of tiny gnats flying about the mighty plane. They appeared to be attacking the giant as vainly as gnats might attack an eagle, for they could not damage the giant machine. The flashing bombs burst in blasts of yellow flame as harmlessly as so many firecrackers.
All that mighty plane was covered with heavy metal plates, fully ten inches thick, and of metal so tough that when the powerful bombs hit it they made no impression, though they blasted tremendous craters in the soil below. From it poured a steady stream of bombs that burst with a great flash of heat and light, and in an instant the tiny planes they struck streaked down as incandescent masses of metal.
Yet the giant seemed unable to approach the city—or was it defending it? No, for it was from the city that the vainly courageous little ships poured out. But certainly it was not these ships that kept the titanic battleship of the air at bay!
Tensely the men watched the uneven conflict. The rain of bombs continued, though all fell short of the city. But slowly around the metropolis there appeared an area of flaring, molten lava, and steadily this moved toward the beautiful buildings. Suddenly the battleship turned toward the city and made a short dash inward on its circling path. As though awaiting this maneuver, a battery of hissing, flaming swords of white light flashed upward, a few hundred feet from the ring of molten rock. As the titanic plane rolled, side-slipped out of the way, they passed, harmlessly, barely missing a monstrous wing.
“Which?” Arcot demanded. “I say the city. No one should destroy anything so magnificent.”
Not a dissenting voice was raised, so Arcot sent the Solarite nearer.
“But what in the world can we do to that huge thing?” Fuller's voice came eerily out of the emptiness. “It has perfect invulnerability through size alone.”
There was sudden silence among the Terrestrials as one of the tiny planes darted forward and dove at full speed directly toward one of the giant's propellers. There were fifty of these strung along each great wing. If enough of them could be destroyed, the plane must crash. There came a terrific crash—a flare of light—and splintered fragments of flaming wreckage plummeted down. Yet the mighty blades continued whirling as smoothly as ever!
What could the Solarite do against the giant monoplane? Evidently Arcot had a plan. Under his touch their machine darted high into the sky above the great plane. There was a full mile between them when he released the sustaining force of the Solarite and let it drop, straight toward the source of the battle—falling freely, ever more and more rapidly. They were rushing at the mighty plane below at a pace that made their hearts seem to pause—then suddenly Arcot cried out, “Hold on—here we stop!”
They seemed a scant hundred feet from the broad metal wings of the unsuspecting plane, when suddenly there was a tremendous jerk, and each man felt himself pressed to the floor beneath a terrific weight that made their backs crack with the load. Doggedly they fought to retain their senses; the blackness receded.
