Falling Into the Cockpit

"Soldier: Wait, does this kid even have a driver's license? Lloyd: No, no he doesn't. Soldier: Then why the hell is he in a goddamn prototype Gundam? Lloyd: Because we are very, very desperate."

- Code Geass: The Abridged Series

A common device whereby a character, usually an Ordinary High School Student, is thrust into piloting a machine that they wouldn't be allowed anywhere near under normal circumstances due to a disaster or enemy attack.

Our hero might have an assload of raw talent, secretly be a Replacement Goldfish, part of the next stage in Human evolution or just play videogames a lot, but whatever the reason, he now has to pilot the thing in the middle of a battle (where he is now a prime target) just to get out of the situation alive. And boy, does he!

Of course, the problem afterwards is how to keep them in the machine after the crisis has passed. It could be that all the normal pilots were wearing Red Shirts that day, or the fact that the machine is kind of an Empathic Weapon, and can only key itself to its first pilot (or just likes him better), but for the time being, he's stuck in the cockpit of an engine of destruction, whether he wants to or not.

It may work in Real Life if lucky or desperate enough, since a lot of machines' operation is designed to be intuitive: controls of a tank (or engineering vehicle based on a tank) from the T-54/T-55 series, for example, are very similar to a truck. The long and demanding training of a machine operator is not needed to drive the machine, but to drive it in a safe and economically viable manner. In a desperate last stand, safety is the last thing people would think about.

Widely used in Mecha Shows. A Sub-Trope of Powers in the First Episode.

Anime and Manga

 * Mazinger Z: The first Humongous Mecha anime used this trope showed it in a more realistic way than later shows. Kouji Kabuto, the first Humongous Mecha pilot, knew absolutely nothing about piloting a giant robot -or any manner of robot, really- and in the first few episodes it shows. Mazinger went on a rampage the first time he activated it because he kept punching random buttons as he tried to learn controling the damned thing (in the original manga he almost destroyed one whole city; and in the anime he almost gets his little brother killed), and he got beaten in his first battles. Sayaka and her father did their best to teach him quickly, but until then he only survived due to Mazinger's impressive weaponry and sturdy body armor... and Kouji soon revealed he was a quick-thinker that could come up with new strategies on the fly.
 * It was subverted with Sayaka, who was taught to pilot Aphrodita A.
 * And averted by Tetsuya and Jun from Great Mazinger, that were trained for years.
 * On the other hand, Duke -and Hikaru- from UFO Robo Grendizer play it straight. Maria, on the other hand, was trained to pilot the Drill Spacer.
 * On the other hand, Kouji avoided the trope twice: Kouji tried to pilot Grendizer once during an emergency and he was unable. He stated the controls were too complicated to him. And in another ocassion he got to pilot Great Mazinger, and he was worried he would have forgotten how handling it. Fortunately, Great Mazinger controls were pretty similar to Mazinger's and he got several years worth of experience for that time.
 * It happens again in Mazinkaiser - when Kouji finds and takes up the titular mecha, it goes on a rampage. It isn't until episode four that Kouji's actually shown controlling it without it falling on its ass.
 * Getter Robo plays it mostly straight. However, in a manga chapter, Ryoma literally shoved a shell-shocked Hayato into the cockpit, placed a helmet-like contraption on his head and told it was a computer would help him to drive the jet. Hayato -who was still shellshocked after seeing a humanoid lizard eating his friends and a giant, flying dinosaur bringing down his school-, tried to protest he did not want to doing this. Ryoma did not care.
 * New Getter Robo makes a Shout-Out with this in Hayato's introduction episode.
 * Kotetsu Jeeg subverts it: Since Hiroshi transforms into Jeeg, he did not need prior training.
 * Raideen subverts the trope. Raideen was a sentient mecha led Akira into his cockpit by telepathy. When Akira woke up from his trance and saw he was into a Humongous Mecha and surrounded by monsters, the first thig he did was screaming: "LET ME OUT OF HERE!". Raideen calmed him down stating he could read minds, so the only thing Akira needed doing was thinking what he wanted Raideen did.
 * Combattler V played it straight with the main characters. The first time they deployed Combattler, they handled it reasonably well in spite of Chizuru was the only pilot could be expected having got basic training. It was justified later: there is one computer built into each one of their helmets, and it help them to pilot it.
 * And it was deconstructed, too. In one episode, a child sneaked into the cockpit, thinking he could use Hyoma's helmet to drive Combattler. As a matter of fact, he could not, and he almost got himself -and everyone else- killed off.
 * It was apparently played straight but quickly subverted in Voltes V: When the Voltes team was roughly shoved into their vehicles, Kenichi protested they did not knew how driving them. Then his mother reminded him flatly they HAD got training to pilot aircrafts.
 * Daimos justified the trope: Kazuya was a space pilot but nobody had taught him to pilot Daimos before shoving him into the cockpit. However, his Motion Capture Mecha was piloted through a mental interface, allowing him piloting it and using his martial arts to fight (and still in the first battle he needed being informed of the weapons of Daimos).
 * Zambot 3 justifies it: Kappei gets roughly shoved into the cockpit of Zambot Ace by his grandparents and big brother. Before he can ask "What the heck am I supposed to do now?" he realizes he just knows how handling it... and his family informs him they taught him to pilot it through Sleep Learning.
 * More or less happens with Amuro Ray in Mobile Suit Gundam... who later is revealed to be a "Newtype". Of course, in addition to being a tech geek to the point he could build his own Robot Buddy (Haro), he got a hold of the Gundam's manual just before he even saw the robot.
 * And Kamille Bidan in Zeta Gundam since he, off screen, reviewed the data on the Gundam Mk.2 by hacking his dad's computer... though Kamile, Teen Genius that he is, does invent his own Mid-Season Upgrade.
 * Judau Ashta in Gundam ZZ, who is initially horrible at piloting.
 * And Banagher Links in Gundam Unicorn..
 * Lampshaded in episode 5, when Bright Noa points out that this happened to all the Gundam pilots before Banagher.
 * And Uso Evin in Victory Gundam...
 * And Garrod Ran in Gundam X...
 * And Loran Cehak in Turn a Gundam who unlike other examples did have a driver's licence ... for a few months.
 * Tobia Arronax of Crossbone Gundam manages to subvert this - when Space Pirates attack, he jumps into a grunt MS, gets defeated but explicitly not killed, and joins up with the Crossbone Vanguard despite two completely separate chances to walk away. And he's still not a terribly competent pilot until halfway through the second volume. Of course, it's subverted another way in that when he takes that first MS, he tells a soldier who protests that he's an engineering student with a license to pilot construction MS, and at the very least he'll be another gun out there.
 * And Kira Yamato in Gundam Seed, the Series basically being a retooled update of the original makes this a necessity.
 * Shinn Asuka in Gundam Seed Destiny, who is a Kamille's Expy of sorts, is actually a trained pilot when the series starts. Not to mention the pilots in Gundam Wing and Mobile Suit Gundam 00...
 * Speaking of Mobile Suit Gundam 00, this trope played straight with  when
 * In Tomino's own Gundam novels Amuro is a trained, if young, military pilot, and is a lot less whiny than in the series.
 * Noticing a pattern here? No wonder that Gundamjack became a word among anime fans....
 * Subverted in Gundam AGE along the lines of Zeta Gundam, the first protagonist had a hand in designing the mobile suit and knows how it works.
 * And completely averted during the second generation. Flit deliberately leaves the Gundam where Asem can find it because he had always intended to give it to him.
 * Inverted in the third generation when Flit literally brings the cockpit to his grandson, Kio, when Kio's home town is under attack. The cockpit then becomes a jet which attaches to the rest of the Gundam.
 * Ericht Samaya/Suletta Mercury Mobile Suit Gundam - the Witch from Mercury manages to be an unusually extreme example by doing it on her fourth birthday, claiming three kills and one assist without realizing the nature of what she's doing. Her mother, the intended pilot, is utterly horrified.
 * Averted in the main series over a decade later, as by the start of the series Suletta has spent years as a mobile suit pilot rescuing miners on Death World Mercury, and regularly plays in simulators.
 * This trope may as well have been built around Shinji Ikari from Neon Genesis Evangelion, apart from his falling into the cockpit of EVA-01 was pretty much planned by Gendo and Ritsuko. Initially, he refuses to pilot it owing to his massive inferiority complex, but agrees once he sees that Rei is in no condition to even stand on her own. Over the course of the series, he continues to pilot it for any number of reasons, all of which he'll express over the series before settling for "Because I have nothing else".
 * Averted with the other pilots. Asuka was selected from age six and trained for years to earn her title. Rei was literally built to pilot the Evangelion...maybe. Kaworu's pretty much perfect for the job. If only he . And Mari? She's just nuts.
 * Of course, this trope is deconstructed. With no training, combat experience or even a clue where the power button is, Shinji basically gets his ass kicked in his first Angel fight until his Eva takes over and beats it up.
 * Ironically, it parallels to what happened the first time this trope was used in Humongous Mecha: Kouji nearly destroyed the whole city as he was trying understanding how piloting the damned thing (and in the anime he nearly got his little brother killed), he got the crap beaten out of him in his first battle because he had no idea of how handling his robot (and he only survived because Mazinger-Z was powerful enough to whistand that brutal trashing... and because his deceased relative encouraged him up), and it took a long while for him to learn how piloting his robot properly. Right like all tropes in Humongous Mecha shows, it goes throughout periodical cycles of Deconstruction and Reconstruction.
 * Akito Tenkawa in Martian Successor Nadesico. He was trying to run for it and the mecha was a handy getaway vehicle; everyone else thought he was volunteering to draw the enemy's attention.
 * Renton in Eureka Seven ends up almost literally falling into the cockpit of the Nirvash typeZERO while delivering a crucial part to it. He then proceeds to unlock its true potential and earn his place as co-pilot.
 * Although really, the cockpit falls on Renton (the Nirvash crashes into his house) before he takes the leap that puts him in the driver's seat.
 * A variant of this trope is used in Full Metal Panic!: Sousuke is already a highly skilled Humongous Mecha pilot when he is forced to pilot the experimental Black Box Arbalest mecha, though he does return to using his normal mech type for a bit eventually he is forced into becoming the Arbalest's designated driver when it turns out the machine's AI calibrated itself to him and can't be reset.
 * Macross offers a deconstruction, as Hikaru Ichijo (a.k.a. Rick Hunter of Robotech), a stunt-flying prodigy, ends up in the cockpit of a Transforming Humongous Mecha/Fighter Jet just when the day needs saving. He proceeds to stumble around and cause a great deal of property damage, because while civilian display team flying is fairly applicable to flying a Jet Fighter, it has nothing to do with robot piloting skills. A crash course from a mentor keeps him from falling into buildings, but he only becomes competent after enlisting in the army and spending a reasonable amount of time in training.
 * Alto, and later with considerably less success to Sheryl, in Macross Frontier. Apparently the fact that Alto (and later, Sheryl) was going to piloting school might have been supposed to justify this, but this is the same as someone who's only partially completed real life flight school Falling Into the Cockpit of the military's latest top-secret fighter! Sheryl's attempt has more realistic results.
 * When Alto tries to get to fly it a second time Ozma punches him in the face for his insolence and has him thrown out. Its only afterwards that Ozma gives him a chance, but he has to go through the proper channels first.
 * In Code Geass, Suzaku is the only soldier available to pilot the new Lancelot Knightmare Frame because he's at base recovering from a point-blank bullet wound while everyone else is out slaughtering civilians. It later turns out that he's the best match for the mecha.
 * The dialog implies that Suzaku's aptitude was tested when he first enlisted, but since only native Britannians are allowed to pilot Knightmares his high marks meant bupkis.
 * He mentioned simulator training at one point, raising the question as to why they would have Honorary Britannians go through KMF simulator training if they weren't allowed to pilot one.
 * For exactly this sort of situation, of course. Nobles can overturn minor rules like that at will, may as well know who has the most aptitude.
 * Besides, someone may have had the idea to test Honorary Britannians as well as pureblood Britannians to 'prove' that the latter are superior to the former, under the auspices of "equal treatment". Naturally, when that doesn't pan out, the results are quietly suppressed.
 * An oft-overlooked example are the Japanese rebels; it's overtly stated that, until a certain point in the series, they don't have any Knightmare Frames of their own, only ones that they've stolen from the Britannians. Given how large the things are, what opportunity would they have had to practice with them enough to be good enough to go toe-to-toe with the military? Particularly Egregious in Kallen's case, since her group operate in a city; at least the JLF could conceivably have found a quiet patch of countryside. Not only that, but she later manages to master the new KFs sent to the Black Knights by Kyouto and Rakshata with extraordinary speed and ease...
 * Actually, her group manages to get hold of a single Glasgow - the older military-use KMF type - and apparently they all try it out. Kallen, of course, is the best, and gets to pilot it in their operation.
 * Lelouch is a close one. He's not amazing or anything, but he handles a Sutherland quite well on his first try, only briefly admitting that it's not as easy as it seems. He's had some minor training, using the test type Ganymede, but that didn't have even half of the features of the modern Sutherland, like the weapon/grappling cable, and the gun, which he uses to great effect in his first deployment. Admittedly, he doesn't even remotely fall in, but he never gets actual training, either.
 * And, to be perfectly blunt, Lelouch is still a pretty crappy pilot. He may be a notch above the common run of Mooks, but against trained pilots he's practically a Mook himself. His most impressive feats only happen because his personal machine was made specifically to play to his strengths; it doesn't fight with guns or swords like regular Knightmares, but instead uses a scattering laser weapon and Beehive Barrier that have to be controlled manually, something only someone with Lelouch's intelligence and quick wits could accomplish.
 * The main protagonist in Zoids: New Century Zero (the first series broadcast in America) Bit Cloud fits this trope to a T. Not only is he thrust into piloting the Liger Zero in the first episode, with no piloting experience beforehand, but the Liger also refuses to allow anyone else to pilot it.
 * In Zoids: Chaotic Century, the first series in Japan and the UK, Van comes across an abandoned Shield Liger in the desert, but would not have been able to pilot it were it not for his robot companion Zeke's help. Unlike many examples of this trope, he keeps piloting it not because others make him, or because only he can, but because the Zoid belongs to him, having previously been abandoned.
 * Simon of Tengen Toppa Gurren Lagann ends up having to pilot the Lagann almost immediately after he finds it, despite his protests. Fortunately for him, it's an Empathic Weapon of sorts. And HOT BLOOD accomplishes everything in TTGL.
 * ALL Hot-Blooded characters end up being able to pilot a Gunman eventually, usually after only a little bit of fumbling. Rossiu manages to learn in the brief time he's in Gurren's cockpit and Kamina's away during the Hot Springs Episode.
 * Gunmen are explicitly stated to have ridiculously intuitive controls. It's said that one just has to "do what feels natural" and the machine practically pilots itself, which does provide some Justification.
 * In keeping with its love of mecha tropes, Magical Girl Lyrical Nanoha does this as well—Nanoha comes into possession of Raging/Raising Heart completely by chance. The third season later implies that trained professionals with similar weapons don't even come close to what Nanoha managed to do immediately.
 * They can't match her POWER, but as Chrono made clear, many likely outmatched her SKILL until she underwent her own brand of Training from Hell. The difference between latent-talent/power and hard-work practice/skill is one of the minor themes of the series.
 * Ayato from RahXephon has this happen.
 * Hibiki Tokai in Vandread is a partial subversion: He was trying to steal the mecha in the first place.
 * Also he made his mech at the Factory, and knows which part is what so he knows, in theory, how to pilot it.
 * Hokuto and Ginga come near the eponymous mecha of GEAR Fighter Dendoh during an enemy attack, while the assigned pilots are still on their way; predictably, they end up inside.
 * In fact, the mech itself picks them up and deposits them in the cockpit.
 * Soukou no Strain also features Sara Werec, another trained field mecha pilot, getting into an experimental machine in the middle of a battle. Her superiors have no idea that she's ever piloted a Strain before.
 * In Orguss 02, Humongous Mecha mechanic Lean is forced to pilot in order to escape an ambush of the cargo plane he was in. This trope is subverted in the following episode; he's brought into the organization that pilots Decimators, but told flat-out that only the best of the best are even considered as pilots. He does fall back in in the last episodes, where he's the best pilot available to stop an Omnicidal Maniac—even though he's blind at the time...
 * Fafner in The Azure Dead Aggressor is a perfect example of this. In the first episode Kazuki has to pilot Fafner despite the fact that up to that point he was not even aware that such a mecha existed.
 * It's later explained that he was made (literally) to pilot the mecha, along with the rest of his generation.
 * In Parallel Trouble Adventure Dual, Kazuki Yotsuga only climbed into that mecha cockpit to rescue its injured pilot... then it slammed shut on him, and he had no other choice...
 * Subverted in Fang of the Sun Dougram - the good guys take the protagonist to their secret base where they keep the eponymous Humongous Mecha and offer to let him pilot it. Suddenly, enemies attack, and just as our hero gets ready to invoke this trope, the Dougram is snatched away by a cargo helicopter.
 * Gram River sort of has this happen to him in Mars Daybreak: It actually came out to catch him, and given that they were underwater at the time, it was more of a sinking than falling.
 * Subverted in Candidate for Goddess. In very first episode main hero of series finds 5 most powerful mechas during a battle and literally falls into the cockpit of one of them. Yet, even when MECH ITSELF was asking him to pilot it and join the battle, he refused because he didn't know anything about piloting.
 * In Zettai Muteki Raijin-Oh. Jin, Asuka, and Kouji become mech pilots only because they happened to be there when the Mech's previous owner was dying. Then it's played literally as Once an Episode, during the school's massive Transformation Sequence, the said pilots are literally thrown into the cockpit before launch.
 * Averted in Break Blade. He was a gifted student in the military academy who couldn't operate a golem because he is an Unsorcerer; he suddenly has to pilot an ancient Golem he can use.
 * Hirono Keita from Betterman. Not only fits the trope to a T; he almost literally falls into the cockpit of the mecha, and happens to be a Dual Type, able to pilot it.
 * Seina Yamada of Tenchi Muyo! GXP is actually tossed into the cockpit, mostly because the people who did so realized the god (the machine he was tossed into) had chosen him. And mostly because he accidentally dragged a bunch of pirates in with him and they wanted him to get rid of them.
 * In Idolmaster: Xenoglossia, Haruka Amami falls into an iDOL's open cockpit after being tossed high into the air by the same iDOL. Later we find that Haruka had passed a blind test on her aptitude as a potential iDOL Master, however, even the ones who set up the test were surprised that the iDOL had a seemingly arbitrary attraction to Haruka, when it had not even respond to a trained and experienced Master.
 * Non-mecha example: in Future GPX Cyber Formula, during a delivery of Asurada GSX to the Fujioka circuit, the machine is attacked, and Hayato Kazami ends up driving it to get out of the mess. Unfortunately, Asurada locks Hayato's driving data, so he has to enter the Fujioka race since Sugo's present driver can't even get the GSX to move and he quit the team because of that.

Comic Books

 * Kurt Busiek's short-lived Shockrockets begins with this trope.
 * In The Black Island Thompson and Thomson commandeer an airplane mechanic to fly a plane to chase after Tintin. The untrained pilot performs a lot of accidental aerobatics, and ends up winning a prize in an aviation contest.
 * Titan (Warhammer 40,000 graphic novel series) starts with Adeptus Titanicus cadet Hekate being assigned to watch a real Titan at work, under command of the Princeps who became a Living Legend (and required reading for cadets like him), at that. Naturally, he is awed and humbled by all this, and then told to not touch anything by someone in the crew. And right in the first mission nature issues a reminder that people who get to be living legends tend to be significantly past their prime, and their commander was already pushing it when he ignored medical advice to take some rest. So the Titan's bridge crew figure that between a cooling body in the chair and Gargant almost in gun range they don't even have time to argue about this, much less sit and wait for properly prepared replacement to arrive — and since they got a spare guy with right connectors in his skull and at least some training for this job right here...

Fan Works
"[Bacon] turned to Alda and aimed a thumb at the control pod. "Ken, you're up." Alda blinked. "What?!" "I said you're up," Bacon replied, sitting down at the controller's station.  "Get in there and get Jet Alone back on our side again." "Me?! Control Jet Alone? In -combat-?" Derek gestured to his massive frame. "-I'm- not getting through that hatch." "But - but I've never - " Derek Bacon fixed Alda with a look.  "Ken, for the past three months, you've done nothing but sit in the Ops Center, eat chips, and kick my ass at robot battle games."  He pointed to the pod.  "Now git!""
 * The Bleach fanfic The Shining Dark does this with Ichigo fittingly. Justified, as Ichigo is already trained and has a strong knack for it.
 * The Second Try: A hilarious example. In chapter 2 Asuka wants to drive a car for first time despite never having had driving lessons. Shinji thinks it is not a good idea, but she argues if she is able to drive a Humongous Mecha, she is able to drive a car. Shortly after she finds out that... nope. She is not able. At least she did not crash the car and them...
 * Deliberately invoked in The Symphony of the Sword from Undocumented Features, when Utena Tenjou is given command of a starship designed from the ground up to be run by a completely untrained crew.
 * When its assigned pilot turns out to be a SEELE mole, Derek Bacon basically shoves Ken Alda into the remote cockpit for Jet Alone during the climactic battle of Neon Exodus Evangelion The Motion Picture: Apotheosis Now:

Film
"Qui-Gon told me to stay in this cockpit, so that's what I'm gonna do!"
 * Anakin Skywalker in The Phantom Menace.


 * And it sort of happens to Luke in Star Wars. Both only had extremely limited experience flying civilian craft before ending up flying starfighters at decisive battles in their respective conflicts.
 * In Luke's case, there's an Expanded Universe Hand Wave / All There in the Manual statement that an X-Wing's controls aren't that different from the Incom T-16 Skyhopper, a very fast, small three-winged civilian airspeeder that's parked in his garage in A New Hope. In the original trilogy novels, he's been grounded from it for reckless flying. He'd damaged the hull, which was why he took the landspeeder when looking for R2. You see him playing with a small model when he's talking to the two droids for the first time. When he talks of "tagging womp rats", he's referring to aerial target practice.
 * "Sir, Luke's the best bush pilot in the outer-rim territories." Film canon. Perhaps Biggs is exaggerating a bit to help Luke get in the cockpit, but this statement strongly implies that he's flown more than landspeeders.
 * Incom is also the same corporation that designed the X-Wing, so it makes sense that there would be some similarities.
 * A different manual, in addition (this being the NPR Radio Drama version of ANH, the same one where Wedge chews him out for that Dissimile) actually has a scene where the Alliance dumps Luke in an X-Wing simulator for a bit of crash course training. He does spectacularly well; Biggs says they threw a fleet at him and he only died twice. Which, I suppose, counts as falling into the simulator cockpit...
 * Also, in the expanded universe, Maarek Stele (the player character of TIE Fighter) was originality a mechanic who was in a fighter (testing it), and happened to be in a position to save a high ranking officer from attack.
 * And Anakin Solo gets to use the Empathic Weapon variant, the hyperspace repulsors of Centerpoint Station. Are we sensing a pattern here?
 * In Flight of the Navigator, a little boy that had been Touched by Vorlons is recruited to pilot a UFO.
 * In Airplane!, Ted Striker is a former Air Force fighter pilot with a severe neurosis about flying. When he musters his courage to get on a jet airliner to chase after his girlfriend, he turns out to be the only one aboard with any flying experience after the pilots all succumb to food poisoning. It doesn't help that the airline officer assigned to talk him down happens to have been his commander during The War.
 * In Zero Hour!, Ted Stryker is a former Air Force fighter pilot with a severe neurosis about flying. When he musters his courage to get on a commercial airliner to chase after his wife (who has left him), he turns out to be the only one aboard with any flying experience after the pilots all succumb to food poisoning. It doesn't help that the airline officer assigned to talk him down happens to have been his commander during The War.
 * In Snakes on a Plane, Troy is the one with the most experience to land the plane - through video games.
 * Thankfully, he gets some help from air traffic control.
 * In the 1980 Flash Gordon film, Flash has to take over over the controls of a plane when the pilots are sucked through the windshield (or maybe disintegrated) by Emperor Ming.
 * Not to mention that he also pilots a Jetbike and the huge "Ajax" cruiser later in the film without much trouble.
 * In The Last Starfighter, Alex is coerced into being the gunner the last fighting starship in the peace-loving part of the universe.
 * Happens twice in Independence Day:
 * Civilian pilots are recruited and given a few hours of lectures before taking to the sky in modern fighter jets without any actual flight simulations and manage to help win a battle against the aliens.
 * Will Smith's character pilots the crashed UFO to dock with the mothership. Despite not knowing about aliens until two days prior, he defends himself as the best choice because he's "seen these things in action" and therefore knows of their maneuvering capabilities.
 * Somewhat averted in The Matrix because when Trinity needs to fly a helicopter but doesn't know how to, she gets the knowledge uploaded to her brain in an instant.
 * In Battlefield Earth, the tribal humans manage to pilot modern fighter jets after practising in simulators for a few days, whereupon they fight and defeat the supposedly "advanced" Psychlos.

Literature

 * The Temeraire series has Captain Lawrence in a similar situation with a dragon, minus the initial battle. He's simply bonded to one of the rarest dragons in the world. A lot of the conflict is derived from various authority figures trying to get Temeraire to let someone else be his partner.

Live Action TV

 * The climactic scene of the Chuck episode "Chuck vs. the Helicopter".
 * This is more or less how Ziggy becomes Ranger Green in Power Rangers RPM.
 * Really, most of the Power Rangers in general fall into this category. It IS a show that depends on Humongous Mecha to win the day, after all...
 * Played with in Super Robot Red Baron: Kenichiro Kurenai does teach his brother Ken about Red Baron's functions and how to use them, during a test run. But then, Troy Horse shows up and attacks Red Baron, knocking it down. Despite this, Kenichiro continues his instructions so that Ken can do a proper counterattack.

Tabletop Games

 * In the Warhammer 40,000 comic Titan, Princepts cadet Hekate is thrust into commanding the massive Warlord Titan Imperious Dictatio when the previous Princeps he was assigned to observe unexpectedly dies in the middle of a battle.
 * R. Talsorian Games' Mekton Zeta is a roleplaying game geared to the Humongous Mecha genre, and this trope may (and probably will) be invoked at least once in any given campaign, no matter the setting.

Video Games

 * In the Super route of Super Robot Wars Alpha, your character gets into the Grungust Type 2 when the plane carrying it crashes into his or her school during a fight between Mazinger Z and the Monster of the Week. On the Real route, your character is a young pilot in the military...who also falls into the cockpit of an experimental mech that happened to be at the base you're assigned to during an enemy attack; this time being the Huckebein Mk II and the Titans. As it turns out, the whole thing was a set-up by Ingram.
 * Ingram pulls the same trick on Ryusei with the Gespenst Type-TT in Super Robot Wars Original Generation. Despite Ryusei's lack of training (aside from his skills playing Burning PT) Ingram calls the idea that Ryusei wouldn't be able to win in that situation "nonsense".
 * In Super Robot Wars Judgement, playing as Touya will have the unit you picked crash into a school building near him, complete with Unwanted Harem while Mazinger Z and its female sidekick defend the school from enemies.
 * It's also lampshaded by Gai early on, who says that anyone that gets a mech that way is destined for greatness.
 * The Z series on the other hand has so far Averted this with its Originals. Setsuko Ohara, while The Rookie, is still a trained pilot, Rand Travis was piloting Gunleon for years, and Crowe is a retired veteran.
 * Nearly every protagonist in the Zone of the Enders series, with the exception of Radium in IDOLO. It helps that the Orbital Frames typically have some sort of AI to help.
 * James Links in Dolores, i is a bit of a subversion: The mecha in question was actually being sent to him in the first place.
 * James Links IS an experienced veteran, while the AI (Dolores) has personality of an innocent child
 * Dingo Egret is actually an experienced pilot by the time he finds Jehuty
 * Dingo however was asked if he would like a refresher VR training program since it was several years since he piloted a military grade frame (He was using LE Vs until he found Jehuty)
 * Played straight in the rare, yet extremely enjoyable 'Mech sections of F.E.A.R. 2. A possible Lampshade in that the manual specifies that only a highly trained 'Mech pilot should even think about touching the controls. Michael Beckett is the furthest thing from a pilot. Michael Beckett in a 'Mech is all but unstoppable.
 * In Xenogears, Amnesiac Hero Fei stumbles into the cockpit of a downed mech when his Doomed Hometown gets caught in the crossfire. Fortunately, he was a skilled pilot before losing his memory. Unfortunately, his forgotten self isn't a very nice guy. And by purest coincidence, the mech he happens to crawl into is a special kind that only he can unlock the true potential of.
 * The concept is used in the video game Steel Battalion, where your character is told he will have many months of simulator training before being allowed near the cockpit of a VT. True to form, the enemy attack, the character gets in the cockpit with the manual (the game is trying to tell you to do the same) and begins mission number 0. Actually much harder than Amuro makes it look...
 * In US version, the hero of Blaster Master just finds a machine lying around there.
 * In Professor Layton and the Unwound Future, the professor must do this at the end.
 * A variation occurs in Ace Combat 5. Archer is a trained pilot...more or less. He's been through flight school, anyway, he just...hasn't completed his qualifications training yet when his base comes under attack and he climbs into a spare fighter. He ends up being a member of Wardog squadron, the most accomplished aces in the game.
 * Technically, most of your NPC crew in Mass Effect 3. The game starts with Shepard bugging out as the Reapers invade Earth, with everyone aboard the Alliance-impounded Normandy forced to come along for the ride. They're all professionals in one field or another (Anderson was planning to use the ship as his mobile command center), so they make the best of it.

 * This is how Taz ends up piloting a space shuttle to save earth from a meteor swarm in the Taz-Mania episode "Astro-Taz". of course, he thinks it's just a video game.
