"So long! See you later!" He pointed his right arm toward the ceiling and sailed lightly into the air. He lowered the angle of his arm and moved smoothly across the huge hangar, floating toward the shining bulk of the rapidly forming Ancient Mariner. He circled the room, rising and sinking at will, then headed for the open door.
"Come out and watch me where there's more room," he called.
Out in the open, he darted high up into the air until he was a mere speck in the sky. Then he suddenly came dropping down and landed lightly before them, swaying on his feet and poised lightly on his toes.
"Some jump," said Morey, in mock surprise.
"Yeah," agreed Fuller. "Try again."
"Or," Wade put in, "give me that weight annihilator and I'll beat you at your own game. What's the secret?"
"That's a cute gadget. How much load does it carry?" asked Morey, more practically.
"I can develop about ten tons as far as it goes, but the human body can't take more than five gravities, so we can only visit planets with less than that surface gravity. The principle is easy to see; I'll show you."
He unhooked the cables and took the power pack from his back. "The main thing is the molecular power unit here, electrically heated and mounted on a small, massive gyroscope. That gyro is necessary, too. I tried leaving it out and almost took a nosedive. I had it coupled directly to the body and leaned forward a little bit when I was in the air. Without a gyro to keep the drive upright, I took a loop and started heading for the ground. I had to do some fancy gymnastics to keep from ending up six feet under—literally.
"The power is all generated in the pack with a small power plate and several storage coils. I've also got it hooked to these holsters at my belt so we can charge the pistols while we carry them.
