But the antigravity apparatus will have to be capable of generating a greater repulsive force than is required for ordinary interplanetary conditions.

Two facts I wanted: antigravity units of the cars do not disturb reception.

‘They have antigravity! Isn’t that it?’ ‘Yes…. Of course, it couldn’t be a complete gravity screen by any means. But it seems to be a good long step toward it.’

How do you get out of here?…Anti-gravity lift.

At first I thought you had some anti-gravity device—but even I know that’s impossible.

The idea of antigravity excited Dennis.

You think they had antigravity or something?

A class-B jamming field renders most of our tractor beams and antigravity lifters inoperative

It’s been two decades since Howard Chaykin’s Ironwolf appeared, the fallen Lord who fenced on far distant worlds and spanned the planets in his spaceship made of anti-gravity wood.

There were no signs of antigravity units on this ship, or even engines.

Great leaps forward in alternative fuels, antigravity and computer technology, solar power, metal fabrication—all these advances in man’s knowledge were leading to new products and improvements in old ones.
