"This category [science fiction] excludes rocket ships that make U-turns, serpent men of Neptune that lust after human maidens, and stories by authors who flunked their Boy Scout merit badge tests in descriptive astronomy."
- Robert Heinlein

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
