In the ''Webcomic/{{xkcd}}'' strip ''[[https://xkcd.com/1244/ Six Words]]'' Cueball plans a more elaborate one (claiming that it works in VideoGame/KerbalSpaceProgram).

* Combined with a WronskiFeint in ''[[Literature/TheFlightEngineer The Privateer]]'' by JamesDoohan and S.M. Sterling. The damaged light carrier ''Invincible'' has a [[ScaryDogmaticAliens Mollie]] flotilla in hot pursuit, so it heads for a recently discovered system that has a pulsar perilously close to the jump point. Since they're expecting it, they're able to slingshot around the pulsar and back to the jump point to escape. The Mollies aren't so lucky; they end up smeared across its surface with their very atoms crushed into degenerate matter.

* The ''Cassini'' spacecraft, currently orbiting Saturn, has taken this trope UpToEleven making two flybys of Venus, one of the Earth, and one of Jupiter to boost her towards Saturn, as well as using Titan's (Saturn's largest moon) gravity to change her orbit, allowing exploration of the Saturnian system.
** Ditto for Rosetta mission, which used four gravity assists (Earth, Mars, Earth and Earth ''again'') to catch the comet 67P.

* The ''Galileo'' spacecraft, which was disposed of in the Jovian atmosphere in 2003, used slingshots from Venus, Earth, and Earth again to gain enough velocity to reach jupiter.

* This is a major plot point in ''Literature/TheMartian'': The so-called Purnell Maneuver involves slingshotting the Hermes so that it can get to Mars before Watney starves; [[spoiler: NASA initially rejects the plan because it risks the lives of the Hermes crew, but Purnell sends Vogel the flight path and the crew mutinies.]]

* In ''Film/TheMartian,'' the Hermes spacecraft performs a gravity assist manoeuvre around the Earth so it can quickly return to Mars.

* In ''Film/TheMartian,'' the Hermes spacecraft performs a gravity assist manoeuvre around the Earth so it can quickly return to Mars.Mars, then have to do another round Mars so they can return to Earth. Unfortunately because of this they can't stop to pick up our protagonist, who must launch into an orbit high enough to be intercepted by the Hermes.

* Joshua Calvert does this in ''Literature/TheNightsDawnTrilogy'', however the drama is in ''how'' he does it, rather than the stunt itself.

* Apollo 13 was launched by NASA in 1970 as the planned third manned mission to land on the moon. An explosion in the oxygen tank of Apollo 13's service module rendered the spacecraft's core systems and main propulsion engine inoperable. Forced to rely on the limited power of the command and lunar modules, Apollo 13 used the Moon's gravity for a circumlunar return.
* Slingshot manouevres around Jupiter and its moons were used to give the Voyager spacecraft the extra impetus and direction to go onwards to encounter Uranus and Neptune. Otherwise they would have run out of fuel and propulsive power and taken a lot longer to reach the outermost planets.
* The ''New Horizons'' probe used Jupiter's gravity to [[http://science.nasa.gov/science-news/science-at-nasa/2007/26feb_grandtheft/ slingshot it]] and boost its speed towards Pluto and the Kuiper Belt.
* The ''Cassini'' spacecraft, currently orbiting Saturn, has taken this trope UpToEleven making two flybys of Venus, one of the Earth, and one of Jupiter to boost her towards Saturn, as well as using Titan's (Saturn's largest moon) gravity to change her orbit, allowing exploration of the Saturnian system.

* A DifficultButAwesome way of saving fuel in VideoGame/KerbalSpaceProgram.

* A DifficultButAwesome way of saving fuel in VideoGame/KerbalSpaceProgram. Experienced players can even learn to pull off this sort of maneuver manually for common transfers like Kerbin-to-Munar-Orbit using dead reckoning and some mental geometry. ''Extremely'' experienced players eventually learn to use elaborate flight plans to slingshot and break spacecraft into and out of velocities nearing fractions of light speed with absurdly small fuel costs. This is both helped and required, however, by the game's only slight indulgence in SpaceCompression. While players can fast forward through the days or months of travel between burns, even high speed, low-tolerance burns can last several seconds or minutes, leaving plenty of time to correct for pilot error or use vector nodes to plan out that next burn.
