"I went [to the top of] Vehicle Assembly Building and looked down, and tears burst from my eyes. The size of this cathedral where the Rockets take off to go to the moon is so amazing."
- Ray Bradbury

Gravity Drive  
  A spaceship propulsion method that uses gravity or gravity waves.  

First use of this phrase.

None of them had ever built a rocketship, had ever seen one in action even. It was centuries obsolete in Galactic civilization. But gravity drives were out of the question. So - they'd had to design the ship from the ground up.
Technovelgy from Star Ship, by Poul Anderson.
Published by Planet Stories in 1950
