* ''[[Mobile Suit Victory Gundam]]'' featured the reactionless Minovsky Drive (a scaled down version of the system used to make battleships fly) on the Victory Gundam and it's successor, the V2, granting thruster-less levitation within atmospheres and in the latter case enough surplus power to sustain the enormous "Wings of Light". |

* Cavorite from [[H. G. Wells]]' ''[[The First Men in the Moon]]'' created anti-gravitational thrust. It ''blocks'' the earth's gravity in the same way lead blocks electromagnetic fields, allowing the moon's weaker to pull the vessel up. [[Mohs Scale of Science Fiction Hardness|needless to say]] [[Jules Verne]] [[Serious Business|had a fit]]. |

* ''Ender In Exile'' actually plays this one fairly straight as far as power goes. The starship engines work with a directional forcefield, dissolving space debris in front of the ship and propelling it out the back. Of course, it was the same dissolving technology that created the Little Doctor Device, a weapon that rips molecules apart, increasing by proximity of mass. Meaning that if someone drove the ship's engine into a sizable mass (say, a planet) the entire structure would unweave. |

** That's still a reaction drive, just not carrying the mass; it's essentially a [[Ramscoop]]. The "Park Shift" drives in use by ''[[Ender's Game|Speaker for the Dead]]'' seem to be true reactionless drives, somehow manipulating reference frames to spin the universe past your ship (at relativistic but subluminal speeds), but Card doesn't go into much detail. (The Park Shift drive is also an inertialess drive of sorts; a spacecraft can instantly switch from a dead-stop to going 99% of the speed of light without having to spend time accelerating.) |
