be able to build domed and sealed cities. But first we could try the nearer planets⁠—Mars, Venus, or some satellites such as our moon. I certainly hope that this machine will make it possible.”

For some time they sat in silence as they sped along, high above the green plains of Indiana. Chicago lay like some tremendous jewel far off on the horizon to the right and ahead. Five miles below them the huge bulk of the Transcontinental plane seemed a toy as it swung slowly across the fields⁠—actually traveling over six hundred miles an hour. At last Morey spoke.

“You’re right, Arcot. We’ll have to think of the interplanetary aspects of this some day. Oh, there’s Chicago! We’d better start the vacuum gas protector. And the radar. We may soon see some action.”

The three men immediately forgot the somewhat distant danger of the metal shortage. There were a number of adjustments to be made, and these were quickly completed, while the machine forged evenly, steadily ahead. The generator was adjusted to maximum efficiency, and the various tubes were tested separately, for though they were all new, and each good for twenty-five thousand hours, it would be inconvenient, to say the least, if one failed while they were in action. Each tested perfect; and they knew from the smooth functioning of the various relays that governed the generator, as the loads on it varied, that it must be working perfectly, at something less than one-half maximum rating.

Steadily they flew on, waiting tensely for the first sign of a glow from the tiny neon tube indicator on the panel before Morey.

“This looks familiar, Dick,” said Morey, looking about at the fields and the low line of the blue mountains far off on the western horizon. “I think it was about here that we took our little nap in the ‘Flying Wheel chair,’ as the papers called it. It would be about here th⁠—look! It is about here! Get ready for action, Fuller. You’re taking the machine gun, I’ll work the invisibility disrupter, and Arcot will run the ship. Let’s go!”

On the board before him the tiny neon tube flickered dully, glowed briefly like a piece of red-hot iron, then went out. In a moment it was glowing again, and then quickly its brilliance mounted till it was a line of crimson. Morey snapped the switch from the general radar to the beam receiver, that he might locate the machine exactly. It was fully a minute before the neon tube flashed into life once more. The pirate was flying just ahead of the big plane, very likely gassing them. All around him were the Air Guardsmen, unaware that the enemy was so near. As the disrupter beam could be projected only about a mile, they would have to dive down on the enemy at once; an instant later the great plane beneath them seemed to be rushing upward at a terrific speed.

The two radar beams were kept focused constantly on the Pirate’s craft. When they were about two miles from the two planes, the neon tube blazed brilliantly with a clash of opposing energy. The Pirate was trying to maintain his invisibility, while the rapidly growing strength of the machine above strove to batter it down. In moments the ammeter connected with the disrupter beam began to rise so rapidly that Morey watched it with some concern. Despite the ten-kilowatt set being used to project the beam, the resistance of the apparatus on board the pirate ship was amazing.

Abruptly the three became aware of a rapidly solidifying cloud before them. The interference of the beam Morey was sending had begun breaking down the molecular oscillation that permitted the light to pass freely through the pirate’s craft. Suddenly there was a circle of blue light about the shadow form, and a moment later the ionized air relapsed into normal condition as the pirate’s apparatus broke down under the strain. At once Morey shut off his apparatus, convinced by the sudden change that the pirate’s apparatus had blown out. He glanced up quickly as Arcot called to him, “Morey⁠—look at him go!”

Too late. Already the plane had shot off with terrific speed. It had flashed up and to their left, at a rate of climb that seemed unbelievable⁠—except that the long trail of flaming gas told the story! The plane was propelled by rockets! The terrific acceleration carried it out of their range of vision in an instant, and as Arcot swung the ship to bring him again within sight of the windows, they gasped, for already he was many miles away.

There was a terrific wrench as Arcot threw on all the power he dared, then quickly leveled the machine, following the pirate at lightning speed. He increased the acceleration further as the men grew accustomed to the force that weighed them down. Ahead of them the pirate was racing along, but quickly now they were overhauling him, for his machine had wings of a sort! They produced a tremendous amount of head resistance at their present velocity, for already the needle of the radio speedometer had moved over to one mile a second. They were following the fleet plane ahead at the rate of 3,600 miles an hour. The roar of the air outside was a tremendous wave of sound, yet to them, protected by the vacuum of the double walls, it was detectable only by the vibration of the car.

Rapidly the pirate’s lead was cut down. It seemed but a moment before he would be within range of their machine gun. Suddenly he nosed down and shot for the ground, ten miles below, in a power dive. Instantly Arcot swung his machine in a loop that held him close to the tail of the pirate. The swift maneuvers at this speed were a terrific strain on both men and machines⁠—the acceleration seemed crushing them with the weight of four men, as Arcot followed the pirate in a wide loop to the right that ended
