** In ''MobileSuitGundamSEEDAstray'', Lowe and the Red Frame ends up facing this problem when a fight with the Gold Frame sends him hurtling into the gravity well of Earth. His Junk Guild buddies, however, use their ship and the massive amount of junk they gathered as a shield to grab Lowe and ride it out to Earth. They wreck their ship in the process, though.

* Fully {{Averted| Trope}} in ''VideoGame/KerbalSpaceProgram'' as of version 1.0, which adds heating to the previously present slowdown effects of drag, necessitating heat shields to prevent burning up on re-entry. Note that the same effects can be achieved by ''any'' high-speed atmospheric travel, not just re-entry.

Note that the same effects can be achieved by ''any'' high-speed atmospheric travel, not just re-entry. As with everything, the effects of re-entry is downplayed in the game: as long as you have a heat shield, it's safe to re-enter the atmosphere (unless you re-enter so steep that you can't slow down enough to be safe to deploy the parachutes until you hit the ground), even if you are somewhat off-angle.

** In the first episode of ''Anime/MobileSuitGundamWing'', Heero's Wing Gundam is shown undergoing re-entry heating while approaching Earth. It would make sense that the Gundams built for Operation Meteor would be made to withstand such heating since they were built on the space colonies for the purpose of going to Earth.

** Contrary to popular belief, Friction contributes a relatively little amount of heat to reentry. The majority of the heat generated is actually from atmospheric compression, the spacecraft is moving so fast that the air in front of it can't get out of the way fast enough, so it gets squeezed, and when you squeeze a gas, you increase its temperature. Of course, most spacecraft do this ''on purpose'', as it's the easiest and cheapest way to slow the craft down enough that it doesn't [[NotTheFallThatKillsYou vaporize on contact with the surface of the planet]].

** Other parts of the SWEU, including some books in the same series, use the friction of atmospheric reentry in various ways. Attaching extra hulls to burn up during the descent lets a squadron of X-Wings disguise itself as part of a meteorite shower, letting them infiltrate a hostile world. In the NewJediOrder, the Wraiths have developed single-person reentry pods with ablation shielding for basically the same purpose.

[[folder: Real Life]] * Generally, this trope is averted in Real Life for spacecraft, since objects moving at orbital speeds move fast enough that when they re-enter the atmosphere, friction with Earth's atmosphere heats their hull significantly (a TruthInTelevision example of {{Friction Burn}}). However, objects can drop from a significant height without burning up if they're not moving at orbital speeds. [[https://en.wikipedia.org/wiki/Red_Bull_Stratos The Red Bull Stratos]] space diving stunt had an astronaut jump from a helium balloon 39 KM from the surface of the Earth. While this arguably isn't re-entry from space, it's re-entry from the stratosphere into the troposphere, which didn't cause the astronaut to burst into flames. * Study of the Moon has revealed that yes, [[https://www.nasa.gov/mission_pages/LADEE/news/lunar-atmosphere.html#.VaLGV_nsl9Q the moon indeed has an atmosphere, albeit a thin one.]] That means that all of the (successful) Apollo missions technically {{Played Straight}}, then {{Averted}}, this trope in succession.

* Averted in ''Film/{{Apollo 13}}'' as TruthInTelevision. * Averted in ''Film/{{Gravity}}'', when [[spoiler: Dr. Stone flies the Chinese capsule from Tiangong back to Earth.]] It's far from smooth. * Averted in ''Film/{{Guardians Of The Galaxy}}''. When Ronan's spaceship enters the atmosphere of a planet, the surface of the ship glows red-hot. It's such a massive ship, however, that its sheer mass allows it to continue with no ill effects. * Averted in ''Film/{{Interstellar}}'', although the effects of re-entry are downplayed from {{Friction Burn}} to "a bad bout of turbulence".

* The {{Macross}} franchise does deal with the friction of re-entry on occasion.

** While it does generate a lot of heat the YF-19 shows just how far craft have come in {{Macross Plus}} since it not only makes a safe re-entry but it does so completely unpowered and spinning uncontrollably while trying to avoid the orbital defence satellites. ** Also comes up in the final battle of MacrossFrontier [[TheMovie Sayonara no Tsubasa]] when its commented that the Macross Quarter will burn up if they enter the atmosphere at full speed. So they make sure to get behind a large piece of debris to use as a heat shield. [[CrazyAwesome Then they proceed to]] ''[[SkySurfing sky surf it]].''

* Averted in two instances in the ''StarWars'' films: ** ''RevengeOfTheSith'' has the "not to worry, we are still flying ''half'' the ship" incident, wherein they even have firefighting ships swoop in alongside to put out the fires of reentry before Anakin [[ComingInHot crash-lands]]. ** In ''TheEmpireStrikesBack'', the probe droid sent to Hoth becomes a meteorite. *** This may be an InvokedTrope (or a case of FridgeBrilliance at least), since [[StarWarsExpandedUniverse EU]] materials seem to indicate ships normally don't glow on reentry. The logic would be "ships don't glow" → "object glows" → "object is not a ship". ** See also the StarWarsExpandedUniverse examples below.

* If reentry is actually shown in the Franchise/StargateVerse, the trope is usually averted. This is used to the heroes' advantage in the ''Series/StargateSG1'' episodes "Nemesis" and "Enemies", when they scuttle the Asgard vessel overrun with Replicators by disabling the shields and performing an uncontrolled re-entry. It should be noted that doing this requires the assistance of Thor (telling them exactly where to place all of the charges to both disable the engines that control reentry and to disable the shields). ** Also averted with a vengeance in "Enemies", where Apophis is killed on board a Ha'tak full of replicators by disabling the engines used to decelerate after leaving hyperspace, disabling the shields, and letting it crash into a planet (after SG-1 safely evacuates of course). ** It's used to their disadvantage in ''Last Stand'', where the enemy tracks Jacob & Daniel's cloaked ship by the heat of its reentry. * In ''Series/StargateAtlantis'', the episode "Lifeline" has [=McKay=] explains that even with the ZPM powering the shields, too steep a descent during atmospheric re-entry could overtax it and cause the shield to fail, while even with it in place, the incredible turbulence could cause the city to break into a million pieces long before it crashes into the surface. * Averted in ''Series/BattlestarGalactica2003'', where we get to see [[spoiler: The Galactica]] dropping through the atmosphere like a giant superheated rock in one episode as part of an AirstrikeImpossible. ** More on an inversion - Galactica wasn't moving anywhere near fast enough for reentry friction, and Vipers were able to leave Galactica without themselves experiencing reentry friction. * Generally averted in ''{{Series/Firefly}}''. Entering the atmosphere is described as a fairly rough and sometimes dangerous act for the ''Serenity'', though the latter is more due to her [[TheAllegedCar state of disrepair]] than the actual heat of reentry. Wash's talent for piloting and Kaylee's talent for [[WrenchWench rapidly jury-rigging repairs]] for failing systems are able to compensate for Mal's lack of talent for making enough money to properly maintain his ship.
