[[caption-width-right:350: Notice how there's no loaders or spotters? This is just the tip of the iceberg...[[note]]The PlayerCharacter in a later level here manages to operate a ''tank'' without the need of additional crew members.[[/note]]]]

->'''Blackadder''': I was under the impression that it was common maritime practice for a ship to have a crew.\\
'''[[{{Cloudcuckoolander}} Redbeard Rum]]''': Opinion is divided on the subject. Yerrs; all the other captains say it is, I say it isn't!
-->-- ''Series/{{Blackadder}}''

Several kinds of vehicles are so complex and require such multitasking that they cannot be operated by a single person: tanks, trains, certain airplanes, etc.

Take the typical tank, for example. If you're in the driver's seat, you have limited visibility and you can't load or fire the main gun. If you're in the commanders seat, you can see all around you, but you can't drive, shoot or load the gun. If you're in the loader's seat, you can't see well or drive (you might not even be able to shoot the main gun). The training points out the fact blatantly: TheCaptain has to sit, look around and give orders, each crewman has a single task to perform and has to do it at his best, this is why absolute trust in your buddies is the most important thing you have to learn in the military.

However, this doesn't seem to be a problem in Fictionland. The Hero (usually a UniversalDriversLicense holder) can easily handle any such vehicle singlehandedly. Common in certain movies and video games (though in the latter case it could be considered an [[AcceptableBreaksFromReality acceptable break from reality]])

Almost universal in the case of HumongousMecha, the notable exceptions being [[CombiningMecha Combiners]].

This can be justified in certain SpeculativeFiction settings by omnipresent computers and simple AI. One might say the ideal number of people for any given vehicle is ''one'': one human to handle the tactics and the moral decisions, and computers to handle the rest of the more mechanical tasks like navigation. The limiting factors, of course, are the amount of multitasking still left to the pilot, and how long the pilot can function at that level.

It can also be justified in emergency situations, at least in aviation. In the case of the death or incapacitation of one member of the flight crew, for instance, the other pilot is always able to fly the aircraft. In fact, it's a requirement that all aircraft be flyable by a single pilot for this very reason. And it's not that rare a circumstance; dozens of pilots have died during flight.[[note]]Note that just because one person can fly a plane, that doesn't necessarily mean they can do all the auxiliary functions at the same time as well. Many aircraft need at least one crew member who isn't focused on actually flying the thing to allow it to fulfill its designated role.[[/note]] Modern diesel-electric and turbo-electric ships are often similarly capable of being controlled by a single crew member in extremis.

[[folder: Naval Vehicles]]
* Parodied in the climax of ''WesternAnimation/TheSimpsons'' episode "New Kids on the Bleech", where pop band manager/Navy Lieutenant L.T. Smash singlehandedly hijacks an ''aircraft carrier''. Well...almost singlehandedly:
-->'''Bart''': Think he's going to do something dangerous?
-->'''Nelson''':How should I know? Just keep loading missiles. ''[loads one into a launcher]''
-->'''[[TheDitz Ralph]]''':''[carrying a missile]'' Pop music's hard work.
* While you can't ''quite'' pilot a battleship or aircraft carrier by yourself in the ''VideoGame/{{Battlefield}}'' series, you can instantaneously hop between a ship's four to six different stations with a keypress to come remarkably close.
* ''Franchise/PiratesOfTheCaribbean''
** This trope is subverted in ''[[Film/PiratesOfTheCaribbeanTheCurseOfTheBlackPearl The Curse of the Black Pearl]]''. Jack and Will only manage to pilot the ''Interceptor'' ''after'' Norrington and his men set the sails. Even then, Jack admits that he can't sail it by himself.
** In ''[[Film/PiratesOfTheCaribbeanDeadMansChest Dead Man's Chest]]'', they say that you could crew the ''Black Pearl'' with six men. Given that their priority was to escape the island, this was probably the number needed just to get it into the water.
* ''Series/{{Blackadder}} II'' features the batshit insane Cpt. Rum, who runs a ship without a crew. Granted, he usually cons passengers by “sailing ‘round and ‘round the Isle of Wight ‘til everyone gets dizzy” then sailing home.
-->''After two days without sight of land, [[EpicFail after leaving Tilbury]]''\\
'''Edmund''': So you don’t know the way to France either.
* In the 1992 Creator/StevenSeagal film ''Film/UnderSiege'', a crew of 3-4 men, out of which no one directly claims to be a trained artilleryman, load, aim and fire the 16 inch main gun of USS ''Missouri'' (BB-63) towards the small target which is a surfaced Diesel submarine. In RealLife, the machinery of each gun took 47 sailors to operate, a specialist observer operated the turret rangefinder and a trained artillery officer used an electromechanical computer to aim the gun. And the submarine was far too close to target with a 16 inch turret gun.
* In ''Film/{{Battleship}}'', the ''Missouri'' is once again operated by a crew that can't even be called "skeleton", about half of whom are UsefulNotes/WorldWarTwo vets (who actually know the systems) and the other half are the crew of a modern missile destroyer used to things like all-digital systems, computers, and GPS. And yet they manage to make the battleship [[spoiler:slide sideways by simply dropping the anchor]].
* In ''[[VideoGame/{{Battlefield}} Battlefield 1942]]'', a single player could seize control of an naval ship and sail it around. There was almost zero reason to do this. [[{{Griefer}} Aside from one reason.]]
* The whole point of the game ''Carrier Command'': two carriers, completed with small squadrons of jets and amphibious tanks, were built to occupy a newly-formed island chain. These were built so a single person could control everything, including said jets and tanks. One of these was further refined to be completely AI-controlled; this AI was subverted by terrorists. You get the other one, and your job is to destroy the other carrier (either directly, or by starving it of resources by capturing its island bases). The result is played straight: you can usually only focus on fighting with one vehicle at a time, with the rest of your forces either on autopilot or docked.
* ''VideoGame/WorldOfWarships''. Whether you're commanding a 32,000 ton aircraft carrier or a smaller 1500 ton destroyer, it's you with hands on everything.
* Singlehanded oceanic sailing in the RealLife. The first transatlantic singlehanded crossing must have occurred already in the 18th century. The first person to sail singlehandedly around the world was Joshua Slocum in 1895-1898 on his two-masted 36'9" ketch ''Spray''. This feat has been [[http://www.joshuaslocumsocietyintl.org/solo/solotable.htm repeated many times]]-- nowadays, there are even solo circumnavigation ''[[EpicRace races]]''.
* A modern RealLife example with "[[http://www.guardian.co.uk/world/2010/nov/14/max-hardberger-sea-captain-pirates-seized Max Hardberger: Repo man of the seas]]". While not a one-man operation, he claims he can "re-steal" a huge cargo freighter with only two or three other guys (one of whom is a chief engineer) right from under the authorities' noses. To be fair, the ships he steals are being held illegally by foreign nations seeking to make a quick buck in bogus "docking fees". Max charges the owners of the ship $100,000 to retrieve the ship and return it safely. He has already done it 15 times. It helps that most systems are computerized these days.
* When WesternAnimation/{{Popeye}} is hired by Castor Oyl in ''Thimble Theater'', the sailor learns that Castor honestly wants him to do all work on his ship. Castor asserts that this is a great honor, being given multiple jobs, to which Popeye retorts that if he's going to do the work of six men, he'd better get six salaries.

[[folder: Tanks]]

In games tanks and other [=AFVs=] are by far the outstanding demonstrator of this trope; more often than not, a single person will be able to drive, aim, and fire the main weapons of an armored vehicle on their own. Games which involve having multiple players operating one vehicle will usually have one player driving and any others operating the vehicle's weapons systems. It is also ''very'' rare to get a real first-person view inside the tank, usually to avoid showing the crew working but also because this is usually not conducive to gameplay. The rest is a RuleOfFun issue; it's rather hard to get people excited about getting to be a tank's loader or radio operator. And in games that ''don't'' involve multiplayer co-op, this is the only way to make tanks playable ''at all''. Even if the tank in question has fully automated loading of its main gun (most don't), every tank that has a turret has the driver seated in a separate compartment with no ability to control the weapons, and everybody in the turret likewise has no ability to drive the tank.

* ''VideoGame/{{Mercenaries}}'' (The game, not PrivateMilitaryContractors)
** Oddly, it's not allowed when driving the smaller vehicles. That missile launcher on your converted pickup will sit there and look adorable until you convince an ally to crew the bloody thing. And at least they make you run up and drop a grenade in a tank's crew hatch before 'borrowing' the whole thing.
* ''VideoGame/{{Crysis}}'' has tanks, as well as jeeps and trucks, whose mounted weapons are controllable from the driver's seat. They just magically swing around. Note that this happens only in easy difficulty; harder difficulty levels require you to change seat in order to control the gun - although that still takes such a short time that it isn't really much of a hinderance.
** Note that, on the higher difficulties, you can still drive the tank and aim/fire the main cannon at the same time.
* In ''VideoGame/CallOfDuty 2'' the player is in control of all of the tank's functions, but it is understood that the tank has a proper crew.
** The same is true of the original ''Call of Duty'''s brief tank segment. The HandWave is that you're the tank commander, and this is gameplay shorthand for you playing spotter and telling the crew what to do.
** Also averted in [[VideoGame/ModernWarfare Modern Warfare 3]], as your [[PlayerCharacter character]] mans the [[GatlingGood minigun]] turret on an M1 Abrams tank to keep [=RPG=]-wielding infantry and helicopters at bay, while the [[NonPlayerCharacter tank gunner]] destroys Russian tanks.
* The ''VideoGame/{{Commandos}}'' series averts this, at least with tanks -- the Driver can drive tanks, but the Sapper must be on-board to fire the cannon.
* The ''VideoGame/{{Battlefield}}'' series.
** Some vehicles (such as the BTR-60 in Battlefield Vietnam) were in fact kinda useless without two people, one to drive and one to shoot. Other vehicles, such as the helicopters in Battlefield Vietnam and Battlefield 2 became significantly more effective with a second crewman to fire more guns, but didn't necessarily require them. But the tanks were pretty much always one-crew killing machines.
* The ''VideoGame/GrandTheftAuto'' series.
* The ''VideoGame/CommandAndConquer'' franchise has plenty of variations.
** ''[[VideoGame/CommandAndConquerTiberium Renegade]]'', in all its gameplay simplicity, although one can set the game so when a second character embarks, he's the gunner. But not only is it optional, it's ''never'' enabled on any server. There is nothing to stop you from operating a Mammoth Tank all by yourself.
** ''[[VideoGame/CommandAndConquerTiberianDawn Tiberian Dawn]]'' originated ''C&C'''s surviving crew concept, where there is a fifty-fifty chance that a single soldier will pop out of a destroyed land vehicle. ''[[VideoGame/CommandAndConquerRedAlert Red Alert]]'' extended the concept to aircraft. Then came ''[[VideoGame/CommandAndConquerTiberianSun Tiberian Sun]]'', and suddenly, you have special hijackers. The idea only went as far as that before it was dummied out in ''[[VideoGame/CommandAndConquerRedAlert2 Red Alert 2]]''.
** ''[[VideoGame/CommandAndConquerGenerals Generals]]'' made it possible to neutralize vehicle crews and take over the vehicle by ordering a single infantry unit into it. [[UniversalDriversLicense And they all know how to drive anything, too]].
*** But only American vehicles have the ability to eject a soldier out of their machines and in spirit of the ''C&C'' games before it, only eject one soldier per vehicle. But it's not just any soldier, either; it's a ''trained'' Pilot, and for very good reason, too: a Pilot carries his experience with him. If he manages to get onto a friendly vehicle, he'll pass his battle experience down to the crew riding that vehicle.
** On the other hand, the [[AllThereInTheManual manual]] states that the reason the Mammoth tank and its equivalents in all games are able to self-repair is because they're large enough to house a full repair crew onboard.
* The Landmaster in ''VideoGame/StarFox''. Probably justified due to the advanced tech of the races in the Lylat system.
** This one does seems to be hardly larger than an Arwing (at most), and just about as complex.
* ''Franchise/{{Halo}}'': Master Chief is capable of operating a Scorpion Tank by himself; in the [[AllThereInTheManual fluff for]] [[VideoGame/HaloCombatEvolved the first game]], it's explicitly stated that a Scorpion can be operated by two Marines ''or'' a single Spartan, as the latter has a neural interface advanced enough to let them to do it. That said, unaugmented troops are also able to operate Scorpions solo in later games, though that might be just a concession to gameplay.
* In ''Film/XXxStateOfTheUnion'', Darius' single handed operation of the tank stretches believability, it does look more awkward than his pursuers (fully staffed tanks) but it is his first time.
* ''VideoGame/{{GoldenEye|1997}}'' does this with a tank in the second level, not to mention a similar tank in [[Film/GoldenEye the original film]]. Plus numerous other vehicles throughout the series.
** Though in the film, he mostly just drives the tank, with apparently limited manoeverability. When he ''does'' fire it, it is completely stationary (implying that he moved about in it) and is being fired at an oncoming train.
** Behind the scenes, Brosnan wasn't controlling the tank, just sticking his head through the front hatch. The real driver was lying prone on the floor underneath him and looking though a concealed glass panel cut out of the glacis plate.
* Rambo does this in ''Film/RamboIII''. He's apparently able to drive, fire and load a Soviet tank with his head sticking out the front hatch.
* Taken to spectacular heights in Creator/KeithLaumer's ''Literature/{{Bolo}}'' series, where massive continent-sieging combat vehicles can be operated by a single pilot. Some of the later models, however, ''[[InstantAIJustAddWater don't even need a pilot at all]]''.
** Though supposedly not artificially intelligent, one Bolo mk III demonstrates the ability to operate entirely without human control. Most Bolo stories feature mk XV or higher units that have no real need of human crew, though almost all marks are intended to carry a commander.
* In ''VideoGame/PlanetSide 1'' the factions' main battle tanks, along with jeeps, bombers, and transport vehicles, generally need at least one other player to man the guns, with the vehicle having to be stopped and a fair amount of motion needed to change slots. However, the Lightning skirmish tank, the Fury and Basilisk [=ATVs=], and the flight-capable HumongousMecha used this trope to be the game's only real single-person ground combat vehicles. Partially played straight in the sequel, where main battle tanks are both driven and can use their main gun with just one crewman, but require a second person to use the secondary weapons. [[CoolCar Harassers]], [[AwesomePersonnelCarrier Sunderers]], and [[GunshipRescue Galaxies]] still require one or more gunners, as the driver/pilot gets nothing to shoot with.
* Many old arcade shooters, when the player gets a tank, would let him crew it himself. ''Front Line'' and ''VideoGame/IkariWarriors'' come to mind.
** ''VideoGame/MetalSlug'', on the other hand, does ''not'' count, given that the tank in question is too small for a second driver/gunner anyway.
** ''Tokyo Wars'' is another example.
* Real-Life example: When [[http://en.wikipedia.org/wiki/Shawn_Nelson a crazy man]] stole a tank from a San Diego National Guard base and began rampaging around, the news anchors describing the action had to repeatedly remind the viewers that he could not operate the main gun alone.
* In the original ''Anime/MobileSuitGundam'', while not all tanks can be run by one man, the crew sizes are still small. TheFederation's Type 61 tank has only a driver & a gunner, with the commanding officer usually taking the latter station, possibly justified by panoramic view provided by tiny cameras on the hull & screens in the interior. The Guntank also starts out with a driver/gunner crew, but by necessity after the driver's death it is later upgraded so it can be piloted singlehandedly. The Zeon Magella Attack Tank, on the other hand plays it straight, with a single pilot in the turret, which can detach & become a fighter jet.
* Interestingly zigzagged in ''VideoGame/MedalOfHonorAlliedAssault''. Stealing an enemy tank in the original game requires escorting a specially trained crew to the tank, but in the ''Spearhead'' and ''Breakthrough'' expansions, both Barnes and Baker manage to singlehandedly operate both German guns and tanks without any problem whatsoever.
* In ''VideoGame/{{Warhawk}}'', tanks need only one player to be both driver and main gunner. A second player can board the tank and fire weapons from its hatch, or preferably, keep it repaired with the [[MagicTool Wrench]].
** A 4x4 driver on the other hand, can only drive and honk the horn. It takes a second player on the 4x4 to fire its machine gun.
* Utterly averted in ''VideoGame/OperationFlashpoint'', in which tanks have the full crew of three (driver, gunner, and commander), though you can do without a commander in a pinch (and suffer impaired visibility as a result). In the tank missions the player typically acts as a tank commander, giving movement orders to the driver and targeting and firing orders to the gunner over the radio. If the tank isn't operating with a full crew, the ones present can switch positions as needed; even one person can drive a tank provided he switches between driving and aiming/firing as needed.
** Also averted for the other types of vehicles in OFP. Boats, helicopters, and even armed jeeps have a separate driver and gunner. In all cases, the driver can still fire (though not aim) the weapons in the absence of a gunner.
** Helicopters and tanks can switch to "manual mode" where the pilot/commander handles firing weapons all by himself but tanks still need targeting orders for the gunner, the commander can't do that himself.
* Every vehicle in ''VideoGame/{{BattleZone|1998}}'', most of which are hovertanks of one form or another. The player can even snipe the driver of an enemy tank, run over and jump in. ''Even if said tank is explicity stated to be an AI-controlled drone.''
* Averted in the old Sony online shooter ''Infantry''. All the large vehicles required a driver and a gunner for each weapon the vehicle had. This meant that the hovertank required 4 players to be fully effective: one driver, one main gunner and two machine gunners.
* Space Marine tanks in ''TabletopGame/{{Warhammer 40000}}'' have very small crew sizes: typically just a driver/commander and a single gunner, with advanced "machine spirits" taking care of jobs that would normally go to other crewmen. (Chaos Space Marine vehicles are much the same, but instead of machine spirits, they have ''daemons''.) The Imperial Guard, who possess more men and less impressive technology than the Marines, have tanks with more conventional crew sizes.
** Tau {{Hover Tank}}s have rudimentary [=AI=]s and automation to take the load off the crew, but keep a larger crew in case somebody gets incapacitated, and to prevent attention from being divided up too much. A Hammerhead Gunship, for example, has three crew members operating "glass cockpits" but can take over any tasks whenever necessary, so a single Tau operator could theoretically singlehandedly pilot the Hammerhead by tabbing between control screens.
* In ''VideoGame/ValkyriaChronicles'' it's implied that the crew of the Edelweiss consists of just Welkin and Isara. The Edelweiss is based on a King Tiger, with five crew positions; it even conspicuously has an access hatch for the radio operator it apparently doesn't have. Later entries sometimes only have a single named person for an entire vehicle.
** The Edelweiss specifically [[JustifiedTrope justifies]] this: it's heavily modified with automated ammo loaders, combined systems, and so on so it can be operated by one commander and one driver/engineer. However, these extra systems require the driver to be specially trained, make the tank far too expensive to be mass-produced, and are implied to require a hideous number of man-hours in maintenance (again, with an overseer familiar with the tank's unique systems) so only the prototype model exists.
* The MMO ''VideoGame/WorldOfTanks'' for the most part averts it. While the player can control a tank with a mouse and a few keyboard hotkeys, the vehicles have NPC crew members representing the commander, loader, gunner, radio operator, driver, and so on. However, losing crew members only debuffs the vehicle. It is possible to lose all crew members except for one, and still operate the tank with all of the main functionalities in order, only receiving a some drawbacks such as lower acceleration, lower view range, slower reload, decreased accuracy, etc.
* Subverted in ''VideoGame/UnrealTournament''. Several of the larger vehicles need a crew of multiple people to work at full capacity. However, the trope can also be played straight as only one pilot is needed for a vehicle's primary functions, like the movement and main weapon. The other pilots only operate secondary weapons or functions.
** The [[TankGoodness Goliath]], the [[CoolPlane Cicada]] and the [[GlassCannon SPMA]] has the driver handling movement and the main weapon at the same time, with the second crew member manning a secondary weapon (top-mounted machine gun for the Goliath, gimbal laser turret and flares for the Cicada, skymine launcher for the SPMA).
** The [[CoolCar Hellbender]] has a driver, one gunner shooting a skymine launcher and another gunner manning a back-mounted laser turret. Surprisingly, this actually has a purpose as the rear gunner is completely exposed and vulnerable to snipers while the other gunner is even harder to snipe than the driver. The driver himself can do nothing but honk the horn; on the other hand, the bots in ''2004'' are scripted to automatically board a honking Hellbender.
** The [[MilitaryMashupMachine Leviathan]] has not one but FOUR secondary positions, each handling a separate turret. As with the trio above, the Leviathan's driver also handles [[MacrossMissileMassacre both main]] [[WaveMotionGun weapons]].
* The World War 2 game ''VideoGame/RedOrchestra'' may be one of the few video games to subvert this. There is a driver, main gun, and machine gun position on a tank; the driver can't see, and the gunners can't move. A good team needs to have the two coordinating their actions during a tank fight. It is possible for a single player to command the whole vehicle by switching between different crewmen, but all actions not performed directly (sitting in the loader seat and driving) will be delayed by a half-second. The delay is explained about by the tank commander shouting the order just before it is carried out by the crewmember. Loading the main gun is done automatically by an AI crewmember.
** It is possible to play it straight as well. Anti-Tank rifles through vision slits, Tank shells through armor, or the shock from artillery can kill crew members in a tank. It's very possible to have a single living crewmember drive into position, climb into the gunner's seat, fire the gun, then climb over and load the next round. It's certainly not as efficient as in most games, as the tank can only perform once action at a time, and there is a delay between actions as the crewmember climes around the interior.
* Stated in the ''VideoGame/{{Earth 2150}}'' [[AllThereInTheManual manual]] that [[TheEmpire Eurasian Dynasty's]] tanks are, essentially, late 20th century tanks that have been refitted to be piloted by a single cyborg.
** Partly justified because they're not using old Soviet/Russian tech but American M1 Abrams tanks, which are already heavily computerized.
* Tanks in ''[[Videogame/MechWarrior MechWarrior Living Legends]]'' are controlled entirely by a single player, despite several tanks being the size of buildings, and in contrast to the [[TableTopGame/BattleTech source material]] where tanks have a regular crew, in order [[PragmaticAdaptation to make them competitive]] with the [[HumongousMecha BattleMechs]] that are controlled by a single pilot.
* ''Videogame/SaintsRow'' plays this mostly straight; generally the Boss is more than able to hop in a tank and wheel around Stilwater or Steelport to his/her heart's content while cannoning anyone nearby. But a tank may also have a gunner position: bring a Saint along and he/she can crew a machinegun, just in case. Sometimes it's a race to see who can shoot down a helicopter first, your gunner or you.
* ''Videogame/HeroesOfTheStorm'' has Sgt Hammer, who pilots a Siege Tank on her own.
* ''VideoGame/FromTheDepths'': The players ships are either controlled by the AI or the player alone.
* ''VideoGame/GearsOfWar2'' averts this with Fenix, Dom, Cole, and Baird taking a specific role to keep the Centaur running and gunning.

[[folder: Spaceships]]
* The ''Series/{{Andromeda}} Ascendant'' is a kilometer-long capital ship with dozens of slipfighters and relativistic missile launchers and for most of the series functions with a crew of ''six''. Albeit justified as most of the original crew of thousands abandoned ship in the pilot and [[SapientShip the AI]] is capable of filling most of their functions.
* Played with in ''Series/DoctorWho'': the Doctor's ([[spoiler:and The Master's in "Utopia"]]) frantic dashing from one control to another while driving the TARDIS led many to theorize that it wasn't designed to be operated by a single Time Lord (though the Doctor does manage it pretty well. Most of the time.) This was confirmed in the commentary of one episode of the first series: the Doctor's TARDIS was designed to have 6 operators.
** This can be surmised by the fact the control console is hexagonal indicating 6 duty stations.
** There's also the fact that when you consider how many times the TARDIS malfunctions or is otherwise inaccurate in arriving at its destination, it seems that the Doctor is just barely able to maintain the thing. It is also occasionally implied that even he is not quite sure how it works, and leaves a certain degree of its operation to chance or trial and error. It helps that this particular TARDIS was a banged-up, obsolete model when the Doctor originally stole it. [[spoiler:And also that it's so old that it's [[SapientShip become sentient]]]].
** In "Journey's End", [[spoiler:the TARDIS is finally fully crewed, and with some to spare as well.]]
** The original set designer of the TARDIS said that he put all the controls and gauges on a control panel in the center of the room because one person was operating it.
* ''Anime/MartianSuccessorNadesico'''s movie shows the humans' One-Man One-Ship project attempting to engineer a human that could handle a ship all by himself, with onscreen results in the form of Ruri (a SuperPrototype?), Harry, and Lapis.
* Most games from the ''VideoGame/{{X}}-Universe'' series allow you to fly capital [[MileLongShip spaceships the size of space stations]] entirely on your own. Made all the more ridiculous because the ships in question are very clearly meant to house other people (at least, the lights and windows all over their surface suggest so), particularly in ''X2: The Threat'' with its capital ship bridges full of empty seats. Handwaved by having the ship's computer handle practically everything, though general fan consensus is that the ships ''are'' manned, just by invisible PlayerMooks. However, AI controlled capital ships (and corvettes) all have a large crew when open a comm channel with them - such as the Captain and navigation officer.
** At the same time, Not only is the player controlling their ''own'' ship, but also the [[PlayerMooks many many ships of their empire at the same time]]. (Although these too are computer controlled, the "living" NPC pilots aren't much smarter than your AI-controlled ships.)
** ''Videogame/XRebirth'' averts this; while capital ships can be operated by just the captain, they will be helpless against attackers; most capital ships fly with at least three crew. The player's ship, the ''Albion Skunk'', always has a pilot and copilot.
* The cargo freighters in ''VideoGame/{{Freelancer}}''. Partly justified because they come across as trailer trucks [[AC:[[RecycledINSPACE IN SPACE!]]]]
** Also, although capital ships are implied to have a full crew, there's several third party mod where you can pilot one of these by yourself.
* Spacecraft in ''VideoGame/EveOnline'' can be controlled by a single person, assuming that said single person is a 'capsuleer', or 'pod pilot' and the ship is designed to accept a pod. Otherwise it takes a full crew to fly a ship. Only a small fraction of humanity has the potential to be pod pilots, and those people are considered a valuable resource, to the point that capsuleers are assured access to clones and that no empire can lay claim to them.
* Derek Smart's ''Battlecruiser 3000AD'' series is this trope taken to the ridiculous extreme. Of course, in-universe, there are crews, but it's actually one man, the player, doing EVERYTHING.
* In TabletopGame/{{GURPS}} there are two ways to do this with spaceships. Either you can have an AI automate the system or you can take a penalty to skill rolls for multitasking, in fact with a big enough penalty it's possible for one person without any "superpowers" to run a ship that normally has a bridge crew of ''60 people''.
* Creator/AlastairReynolds:
** In the ''Literature/RevelationSpace'' 'verse, the extreme size of the lighthuggers (around 4 kilometres long in most cases) are often contrasted with their relatively tiny crews; in Galactic North, the story revolves around two such ships that are crewed by single people.
** In ''Literature/HouseOfSuns'', each [[SendInTheClones shatterling]] is given his or her own starship and expected to go it alone, minus the odd passenger.
* Any brainship in Creator/AnneMcCaffrey's "Literature/TheShipWho" series could technically run with just the shellperson controlling it -- just one person. However, these ships are usually paired with a normal human, resulting in a crew of two.
** The Brawn is primarily there to keep the brain company, provide a physical presence outside of the ship and provide a layer of redundancy. In theory the brain can use their remotes to handle all routine tasks (such as maintenance, cargo handling etc.) but having the brawn on board means that repairs can be made if the brain loses that capability.
* A ''Franchise/StarTrek'' novel has Scotty control an entire (TOS-era) starship himself by basically rigging a ([[SchizoTech TNG-era]]) shuttlecraft's controls into it, so that the ship basically does whatever you tell the shuttle to do. Of course, he ''is'' Scotty. Even so, the setup proves unable to stand up once the ship begins to take damage in combat (no crew being present to repair it while Scotty was driving the ship), and it was never meant to be anything other than a one-time kludge solution.
** ''Franchise/StarTrek'' spaceships (at least of the ''Series/StarTrekTheNextGeneration'' era) can generally be operated by a single person thanks to the advanced computers (though maintenance requires a complete crew).
** Another TNG novel had Picard being briefly moved to an alternate-reality Enterprise-E. It was noted that ships in that reality were specifically designed to have a crew of one, using bio-engineering to connect one's brain directly to the ship. Picard is rather horrified by this system, comparing it to the Borg.
** One episode of TOS features a test of a new type of computer capable of running a starship all by itself. There turn out to be a few problems with this, though the computer not being able to make the ship do whatever it wanted ''wasn't'' one of them. So the technology at least existed even by that time.
** In another episode, "The Doomsday Machine", Kirk, Scotty, and a few other crewmen repair the badly damaged starship ''Constellation'' enough to use it to distract the titular Big Dumb Object away from the ''Enterprise''. Eventually, Scotty is able to run all command functions and a self-destruct button to the auxilary control room, enabling Kirk to ram it down the alien craft's throat.
** In Recap/StarTrekS1E10TheCorbomiteManeuver Balok runs his ship alone. Justified, as he's a SufficientlyAdvancedAlien.
** In ''Film/StarTrekIIITheSearchForSpock'', Scotty automates the damaged ''Enterprise'' sufficiently to fly it with only a few people... though the system breaks down when they end up in a combat situation.
** Subverted in one episode of ''Series/StarTrekTheNextGeneration'' when this is one more reason Beverly Crusher realizes something is HORRIBLY WRONG when only she and Picard are piloting the ''Enterprise''. She asks him why there is no crew and he responds "We never needed anyone else."
** In ''VideoGame/StarTrekOnline'', starships ''have'' crews, but they don't actually ''need'' them. The only effect from getting all your crew killed is the ship stops RegeneratingHealth. Similarly, your bridge officers only provide the ship with some additional powers, you can fly the ship just fine by yourself.
** ''Film/StarTrekIntoDarkness'', the ''Vengeance'' was designed to need a much smaller crew than its predecessors and could be operated by one person if necessary. [[spoiler: This is quite fortunate for Kirk, Scotty, and Harrison when they board it to capture the ship from Marcus, then again for Harrison when he truly does have to pilot it by himself later. The novelization also makes it clear that Harrison's ability to fly the ship solo into combat in an effective manner is also largely due to his superhuman mental abilities and reflexes]].
** In ''Series/StarTrekVoyager'' we meet the terrifying Species 8472 and their bio-ships. Each ship requires only a pilot and the ship itself is extremely formidable, being able to destroy multiple Borg cubes in seconds. The pilots themselves are no slouches; they're able to resist assimilation, have psychic powers, and their cells are extremely virulent, meaning a slash can poison the victim and kill them if left untreated.
* Franchise/StargateVerse
** It's actually come up several times in the Verse when the main characters get their hands on a spaceship but the fact that one person or the few present ''cannot'' fly it by themselves is the source of drama.
** ''Series/StargateSG1'': While an early appearance by an Asgard ship has Thor refer to having evacuated his crew when the ship was overrun, later appearances seem to imply it's just him aboard. He's certainly able to operate all its functions without even leaving his chair. This is most likely the same situation as in ''Star Trek'' above: Automation allows a single person to operate the ship (although possibly not as well as a full crew), but maintenance is impossible. There is no sign of anything like maintenance bots, for instance.
** ''Series/StargateUniverse'' has this as a major plot element -- the ship can handle itself, but if they need to turn off the autopilot so they can do something else it's quite a chore.
* In ''VideoGame/MassEffect2'', the Cerberus-built Normandy includes an AI that could theoretically take over pretty much every aspect of running the ship, apart from helming it, and allow it to be run by a crew of one. Cerberus intentionally made the AI unable to do so, [[spoiler:at least without overriding its safety constraints which you have to do late on in the game]], and thus the ship features a full human crew complement.
** However, while the ship's AI can theoretically ''pilot'' the ship, she can't ''maintain'' the ship, and would need at least human crewmen to act as engineers. In addition, any task performed by crew frees up processing power for other tasks, which proves crucial when the AI needs to focus all available resources towards hacking the Collector ship to allow Shepard to escape.
*** In the third game, the AI gains control over a humanoid robot which could theoretically maintain and helm the ship, although this is never put to the test.
** She also makes it clear that while she ''can'' pilot and operate the ship, she ''shouldn't''. A skilled organic pilot is superior to full AI control simply because her maneuvers would be too predictable.
* Various ships in the Franchise/StarWarsExpandedUniverse have large crew complements which for one reason or another end up being cut down.
** ''Literature/TheCourtshipOfPrincessLeia'' has Luke Skywalker flying the Falcon - whose unmodified version is supposed to be controlled by at least three people with another two at the guns, but has been altered extensively - and using the Force to operate all of the controls, including the quadlasers, with extreme precision.
*** The Falcon can actually be operated entirely by one person, but firing the main guns from the cockpit with any kind of accuracy is damn near impossible (Luke's ability to do so in the above novel, even with the Force on his side, was considered a mighty achievement). And if something breaks down (like the hyperdrive did in ''[[Film/TheEmpireStrikesBack TESB]]'') there's no way to fix it without leaving the pilot's seat.
** In ''[[ComicBook/XWingSeries Wraith Squadron]]'', the eponymous twelve-member squadron manages to capture a [[http://starwars.wikia.com/wiki/Night_Caller modified Corellian corvette]] and immediately call for crewers. They crew it themselves until the New Republic sends more people, but have some difficulty.
** In ''Literature/TheThrawnTrilogy'' it's a plot point. In fact, the ''central'' plot point to the second book of the trilogy. Dreadnaught-class heavy cruisers usually need a crew complement of sixteen thousand people, but one fleet - called the [[KatanasAreJustBetter Katana Fleet]] or the Dark Force - was fitted with [[http://starwars.wikia.com/wiki/Slave_circuit slave circuitry]] which reduced the needed crew to 2200 each. And meant that when the crewers on the flagship caught a hive virus, went insane, and programmed a random jump, the entire fleet was lost in the depths of interstellar space, at least until they were accidentally found many years later. At which point, the race is on between two rather evenly-matched navies to get the ships first and tip the balance in their favor.
*** Many smaller ships throughout the Expanded Universe also have slave circuitry, which fell out of favor for warships after the Katana Fleet disaster but remains highly advantageous for smaller freighters and civilian space yachts. Han Solo, on the other hand, specifically refuses to include such a system on the Falcon, because he doesn't want anybody else being able to remotely control his ship, ''ever''.
** ''Film/RevengeOfTheSith'' has Anakin and Obi-Wan taking control of a [[http://starwars.wikia.com/wiki/Invisible_Hand modified Providence-class destroyer]] and landing it entirely on their own. The whole scene is more PlayedForLaughs than any of the above, however, considering the ship is literally breaking apart as they're flying it.
** One humorous dialogue option in ''VideoGame/KnightsOfTheOldRepublicIITheSithLords'', while exploring a capital ship whose crew had all been mysteriously slain, has the player suggest commandeering the ship to escape the facility they're trapped in. Cue [[DeadpanSnarker Atton Rand]]:
--> '''Atton''': What, with the huge crew we've brought with us?
** And then there's the Errant Venture, the only Star Destroyer in private hands in the entire galaxy. Belonging to Booster Terrik, it's basically a mobile starport for smugglers and a cool symbol of power - which is constantly falling apart, because it turns out that trying to fly a Star Destroyer with what amounts to less than even a skeleton crew is not exactly easy.
** The Literature/NewJediOrder novel ''Rebel Stand'' sees the Super Star Destroyer ''Lusankya'' specially modified for use in a ramming attack. Some of the modifications allow the ship to be controlled by one person, though this task is made somewhat easier by the fact that all of the ship's weapons have been removed, so the pilot's only function is to maneuver the ship.
** ''Film/TheLastJedi'' has [[spoiler:Admiral Holdo]] singlehandedly fly a Rebel cruiser and [[spoiler:use it to ram the First Order command ship]]. Earlier, during [[spoiler:Poe's attempted mutiny against Admiral Holdo]], the bridge is similarly deserted, with only a couple others present and [[spoiler:Poe]] handling nearly all of the bridge tasks personally.
* Most starships in the later years of ''Literature/KnownSpace'' history are computer-automated to the point that a single pilot is all the crew you need. Of course, the cruise ships, military vessels, and exploration craft all carry larger crews for other reasons (guest comfort, backup in case of death or injury, and so on), but they don't ''need'' to if all they want to do is get from Planet A to Planet B.
** It is perfectly possible for the autopilot to do ALMOST the entire flight, except for one minor detail: Traveling too close to a massive body while in hyperspace will destroy the ship, and a mass sensor, the only system capable to detecting such a hazard while in hyperspace, is a psionic device. That is, it operates only because a mind is examining the output.
* In ''Literature/PathOfTheFury'', there is exactly one kind of interstellar spacecraft capable of being crewed by a single person, and that is the alpha synth. Even small courier vessels or heavily automated larger vessels generally require a crew of at least six.
* ''VideoGame/BattlestarGalacticaOnline'': You can take command of starships that should need multiple crewmen, but no mention of those is ever made.
* ''Series/{{Farscape}}'' has ships operated by a pilot grafted on them, and some one-man crafts and fighters. However, the Luxan fighter has a pilot and gunner seats; D'Argo asks Crighton to pilot for him when he needs to go shoot something with it.
** Leviathans and Pilots are arguably a subversion. A Leviathan is a LivingShip and can fly just fine by itself, but it needs a Pilot if it ever wants to carry passengers since it can't maintain things like life support on its own.
* Ships in ''Literature/TheHistoryOfTheGalaxy'' books can operate with any number of crewmembers or even without them due to the fact that [[InstantAIJustAddWater AI modules]] are factory produced in great numbers. This could be one of the reasons why a 7-kilometer flagship cruiser can function with a crew of ''150'' (most of the maintenance is done by droids). In one novel, a single woman (with no combat experience whatsoever) commanded a fleet of highly-advanced warships set to full AI control. She used most of them in a suicide run against a heavily-defended world.
* The trope is invoked in Creator/SergeyLukyanenko's novel ''Literature/{{Competitors}}'', where a Moscow freelance journalist is transported (sort of, he stays on Earth, but his duplicate is sent) to a space station far from Earth to pilot a ship in a RealLife recreation of an online space sim. He can explore the stars, [[AsteroidMiners mine asteroids]], settle on a colony, engage in [[SpacePirate piracy]], join the [[SpacePolice patrol]], fight alien hordes, etc. When he gets his first ship, he notes that the ship only has one set of controls, which are ridiculously simple for anyone who has ever driven a car (there are even gas and brake pedals) and were obviously designed for an average human. In fact, most of the precision maneuvering is done by the ship's computer, and the control are there to let the computer know what the pilot wants. Even giant higher-level ships are only designed with one person in mind, which results in the OldSchoolDogfight being the primary form of combat. Later, when the alien Bugs attack the station, the protagonist's wing is ordered to pretend to retreat and then strike at the Bugs from behind. The protagonist observes that this should be impossible in a normal space setting, where ships would have rear-facing turrets manned by people (or Bugs). However, it works perfectly, and he concludes that the Bugs are also engaging in this trope. Close to the end, however, a group people rigs one of the larger ships to have multiple specialized consoles, averting this trope.
* The backglass for Creator/SternElectronics' ''Pinball/{{Flight 2000}}'' pinball depicts a fleet of {{Sleeper Starship}}s flying through space, each with a single HumanPopsicle within.
* Zigzagged with H'rulka ships in the ''Literature/StarCarrier'' series. The 20-kilometer vessels are actually [[DetachmentCombat several ships docked together]], each crewed by one 200-meter LivingGasbag. Except the H'rulka is really a colony organism.
* The titular character in Creator/GeorgeRRMartin's ''Literature/TufVoyaging'' singlehandedly crews the ''thirty-kilometer-long'' Old Earth Ecological Engineering Corp biowar seedship he calls the Ark. It originally had a crew of 200. He is able to do it through the centralized computer system on the bridge, vast amounts of automation and self-repairing gear.
* Generally averted in ''Literature/PerryRhodan'', where most ships tend to have crews of some reasonable size and even fully robotic ones usually feature at least mobile sub-units capable of some level of independent operation and reasoning if not an outright crew of independent robots altogether (Posbi "fragment ships" are a good example of the latter). However, ships constructed by sufficiently {{higher tech species}} sometimes play this trope quite straight -- famously, the classic "spore ships" built to spread life and intelligence throughout the cosmos for one faction of the setting's Powers That Be were designed to have a single pilot handling the whole 1126-kilometer diameter sphere and overseeing its operations.
* It's possible to reduce crew requirements in ''TabletopGame/{{Traveller}}'' with Fire Control, Evade, and Intellect programs. But they are rather expensive and limited by the capabilities of the ship's computer.
* In ''TabletopGame/HcSvntDracones'' ships built by Applied Sciences and Robotics can run with 10% of their normal crew complement, but their computer rating is drastically diminished if they do so. The [[LivingShip bioships]] of Transcendent Technologies Inc can also run with such small crews, but to do so the helmsman has to fight to maintain control.
* You can try this in ''VideoGame/ArtemisSpaceshipBridgeSimulator'', despite it being designed for [[CoOpMultiplayer a crew of six]]. In theory you only need Helm (most of the time) and Weapons (briefly, switching to it to actually fire then back to Helm while you reload): ignore Science since all unknown contacts are probably hostile, ignore Comms except when you need to change starbase production, leave Engineering settings at default, and do without a Captain since you know your own orders. To say the least, this is more difficult (at the same difficulty level) than playing with a full crew (assuming they are competent and cooperating).
* The Protoss Carrier in ''VideoGame/StarCraft'' is, as the name implies, an AirborneAircraftCarrier that can carry eight additional fighters inside (in the game, at least; the numbers might actually be larger). There normally seem to be large crews, but if there is an emergency (or a HeroicSacrifice), it can all be helmed and controlled apparently by ONE Protoss. With his mind, no less. The fighters are supposedly mostly autonomous robot vehicles which receive targeting information and group launch/recall orders from their carrier (and manufacturing factory), making this a bit more plausible.
* ''VideoGame/FTLFasterThanLight'' splits the difference. One person ''can'' control the ship by themselves, but without additional crew at the various duty stations for weapons, shields etc they function noticeably worse. And that's before they start taking damage.
* The nature of [[CastFromHitPoints crew as damage points]] in ''VideoGame/StarControl'' means that at the end just one crewman (assumed to be her [[TheCaptain captain]]) can be controlling the entire ship. This becomes odd in some ships such as the Earthling Cruiser or the Spathi Eluder that show two crewmen in the animations, and continue so even in that case.
* ''VideoGame/{{Halo 4}}'' has the ''Mantle's Approach'', an enormous Forerunner vessel piloted by one Forerunner, the Didact. This is justified since the Forerunners are SufficientlyAdvancedAliens with near-godlike abilities.
* The title ship in ''Anime/QueenEmeraldas'' is crewed by a single person, her eponymous captain, possibly justified by Emeraldas being one of the two legendary pirate captains of the Anime/{{Leijiverse}} and by the ship having an advanced AI (whose personality, however, is apparently a copy of her captain's, too). Metaphorically, this serves as a constant reminder that [[LonelyAtTheTop for all her power, Emeraldas is forever consigned to loneliness]].

[[folder: Other]]
* Averted in the MMO-FPS ''VideoGame/WorldWarIIOnline''. More of a Simulator than a true FPS, driving tanks and boats required multiple crew members for multiple respective positions; The driver is, in fact, unable to shoot, has poor viability, etc. The player can swap between positions easy, however, but that doesn't lend much good in battle when one well-aimed shell can take you out.
* Lampshaded in ''VideoGame/ArmoredCore: For Answer''. The megacorporations in the game world used to rely on HumongousMecha which played this trope straight, until they figured out that [[PhlebotinumRebel it was too dangerous to leave that kind of firepower in the hands of a single pilot]]. Consequently they started building {{Military Mashup Machine}}s with hundreds of crew instead.
* The video game ''[[Creator/DaleBrown Megafortress]]'' illustrated this literally - there are several different stations all simulated (pilot, weapons officer, EW officer, etc), but it's up to the player to hop around to all the stations to control them. This can be tricky when you're trying to turn around to bring some weaponry to bear while firing a missile at the [=MiG=] heading at you while trying to get the bomb bay doors closed and fiddle the ECM settings. Never mind the engine that's on fire from the last hit and the fact your attack radar is still on, broadcasting your position to the world.
* Several vehicles in the ''VideoGame/StarWarsBattlefront'' games have multiple crew slots. The Assault Gunship has five: pilot, copilot, left, right & tail gunners. Only a pilot is required to drive and fire the main weapons, but a solo operator can switch rapidly from slot to slot if he wants to.
** Taken to an extreme with the snowspeeders from the [[Film/TheEmpireStrikesBack Hoth map]]: in the first ''Battlefront'', a single player can fly one towards the Empire's AT-AT's, switch to the rear turret, fire the cable at its legs, then ''immediately'' switch back to the pilot's seat and tie it up. [[GameBreaker Quite understandably]], ''Battlefront II'' added a forced delay between firing the cable and switching seats, making it nearly impossible to take an AT-AT down that way without two people.
* ''Film/{{Airplane}}'': Ted Striker flies a modern jet airliner by himself, a task that normally takes a crew of three (pilot, co-pilot, flight engineer).
** The film sort of [[LampshadeHanging hangs a lampshade]] on this with what confronts Striker when he first enters the cockpit: a slow pan across a literally endless array of dials, levers, switches and knobs. The Boeing 707 seen ([[JustPlaneWrong but not heard]]) in the movie can be flown for a short time with a crew of one (the pilot). For longer flights, you need a flight engineer to keep an eye on the airplane's mechanical systems, and if you want to reach your destination, you add a third: the navigator. Modern jetliners only need a crew of two, the flight engineer's position having been given to computers.
** It's long been a standing joke in the airline industry that the flight crew will soon be reduced to just a man and a dog. The man will be there to feed the dog, and the dog will be there to bite the man if he tries to touch the controls (though [[FridgeLogic one has to ask what kind of dog would (literally) bite the hand that feeds it]]).
* There were real-life attempts to create one-man armored fighting vehicles back during the 1920s and 1930s; they belonged to a class of vehicles known as "tankettes." The French, for example, wanted to create a sort of infantry replacement; one man would drive the vehicle and take care of everything, and he'd also be armed with a machine gun. In practice, it was unworkable, and the concept was abandoned. To be perfectly fair, during the past century there has been a significant trend towards smaller crew sizes, due primarily to automation.
** However, the minimum crew size in a turreted vehicle is still three, because the only crewman who can realistically be replaced is the loader. And most western armies have avoided autoloaders because a good human loader is much more reliable, faster and more flexible. An autoloader can't help change a track, pull maintenance, stand guard, or sub for another crewman, either. He also serves as an extra pair of eyes to watch your back when he isn't loading.
** Also, an autoloader can break down. Or, in the case of some Russian tanks, inadvertently load the gunner's arm instead of a shell. And then break down.
** Furthermore, reducing the crew to just one is probably inadvisable simply for morale reasons.
* How a HumongousMecha show plays this trope is usually a good indication of how Super or Real it is.
** The titular HumongousMecha in ''VideoGame/MetalArmorDragonar'' require high-powered AI to aid in operation in order to keep the crew size down to a single person.
* In the ''VideoGame/AceCombat'' series, when you choose any aircraft with a crew of 2 or more (F-15E, F/A-18F, F-14, etc...), you still control all of its functions yourself as if it only needed one person. However, when you look at the actual plane's model, you can see a guy in the back seat, presumably doing his job alongside the pilot - which gets silly when, for plot reasons, someone is forced to eject from their plane but only one parachute is seen.
* ''VideoGame/AirForceDelta Strike'' does this for its 2-man fighters as well.
* As does ''VideoGame/{{HAWX}}'', though for at least one mission in the first game the guy in back is actually acknowledged (he's the one training you in the game's main gimmick).
* Before it entered beta, this was weirdly subverted by ''VideoGame/VectorThrust'', where ''nobody'' was flying the planes.
* In ''VideoGame/WorldOfWarcraft'' the [[FragileSpeedster Catapults]] used during [[PlayerVersusPlayer Wintergrasp]] fights have space for only one driver/gunner. The [[JackOfAllStats Demolishers]] also has a driver/gunner but have space for two passengers who can fire their own ranged weapons (bows, guns, etc.) from their seats. The [[MightyGlacier Siege Engines]] have a ram controlled by the driver, a turret-mounted cannon that requires a separate gunner and two passenger spots. Similar vehicles exist on the Isle of Conquest, Ulduar and other in-game locations.
* ''VideoGame/{{Prototype}}''. While Alex has learned how to pilot APCs, tanks and helicopters by consuming people trained to do so, he can somehow operate them all by himself.
** Maybe with his tentacles?
** Come to think of it, this guy has the ability to shapeshift into basically anything...it is not a far stretch to assume he just fills the entire vehicle with himself and can then easily operate all the switches, buttons and levers as he pleases.
* Inverted on ''Series/TopGear'': In a crossover challenge with German motoring show ''D Motor'', the presenters had to drive double-decker cars, with one person on top steering and a second person on the bottom operating the pedals and gearshift, thus turning a vehicle that normally is Crew of One into Crew of Two.
* Trains can run with a Crew of One, it's called DOO (Driver Only Operation). A diesel or electric locomotive only really needs one pair of hands to operate all essential functions, but a second crewman is often carried to provide a second pair of eyes on the track ahead and/or to take over when their colleague's mandatory rest period is up.
** Real Life Subversion: [[http://tfl.gov.uk/dlr Docklands Light Railway]] runs trains with a crew of nought. Though the on-board Passenger Service Agent is trained to become the Crew of One and drive the train if computer operation fails.
* Both used and averted in ''VideoGame/AssassinsCreedBrotherhood''. The [[spoiler: Bomber]] is justified as only having enough space for one man. The [[spoiler: Tank]] needs three people to run it, though gameplay usage does not act as such. The [[spoiler: Machine Gun]] is clearly meant to have a driver and gunner, but you get separate parts of the mission for using both and during the latter the thing is on autopilot or something. The [[spoiler: Naval Weapon]] clearly is meant to have a gunner and driver too and this time Ezio has to switch between the two positions as necessary.
* Almost all fighter aircraft have a one-man crew, who both flies the aircraft and operates the weapons. Some, however, have two crew members with one performing each task, such as the F/A-18E Super Hornet, F-15E Strike Eagle, and MiG-35.
** Many exceptions to this are electronic warfare variants of what are otherwise single-seat fighters (themselves often based on a two-seat trainer variant). The second person runs the (much more extensive) electronic warfare equipment. There are also fighters that only exist in two-seat configurations, which often carry much more elaborate electronics packages than single-seat aircraft do (since there's another person there to operate the more complex systems), such as the F-14 and A-6.
** The electronic warfare variant of the A-6, the EA-6B Prowler, actually has the room to seat ''four'' people, the pilot and three electronic countermeasure officers, though closer to the trope it's not uncommon for Prowlers to fly without a third officer. The EA-18G Growler, an F/A-18 variant meant to replace the Prowler in Navy use, drops the crew down further to just one officer for the same workload.
* Can be seen in ''VideoGame/HalfLife2'' with both dune buggy and air boat. Being piloted by one fellow is reasonable enough, but that same fellow being a simultaneous driver and gunner? Not so much. Multitasking capabilities aside, there is a certain minimum of available arms required to perform both tasks, which can lead to only one conclusion: Gordon Freeman has an extra set of invisible hands. This would also explain how he can [[LadderPhysics climb a ladder while reloading a gun or firing it at an enemy behind him]].
** Well, [[Webcomic/{{Concerned}} he can]] [[http://www.screencuisine.net/hlcomic/index.php?date=2005-05-10 pick up objects without using his hands.]]
* Averted by all multi-crew vehicles in the ''VideoGame/{{Tribes}}'' games. Even the HoverTank has a driver and gunner, to say nothing of the larger aircraft where there is always a pilot who only handles flight and a tailgunner whose main duty is chucking flares at incoming missiles. Bombers have a weapons officer to handle the onboard ordnance and gunships have four passenger slots whose occupants can use their own infantry weapons to rain DeathFromAbove; a single-man gunship is just a big fat target but a fully loaded one with everyone sans the pilot wielding mortars and missile launchers is a flying fortress. If you want to switch positions, you have to physically disembark the vehicle first.
* An example from RealLife. Sterling Marlin became one of these during the 2002 Daytona 500 NASCAR race, climbing out of his car during a red flag stoppage to look at his right front fender. Unfortunately, according to NASCAR rules, this is illegal, and he was sent to the back of the lead lap when the green flag came back out. The worst part is that [[WhatAnIdiot he was leading the race when that happened!]]
* Creator/SergeyLukyanenko's ''Competitors'' novel mentions this absurdity several times in relation to starships. Humans on the Platform build these ships using matter synthesizers (i.e. replicators) based on plans in the station's database and available raw resources. While there are plenty of small fighter-type ships, even the giant ships have only one standard control console. Also, the entire thing has controls similar to a car, including ''pedals'' for acceleration and braking, in order to allow any human to use them. This is justified in that the station and the plans were created by aliens to be reminiscent of a web-based space exploration game (the game actually exists in RealLife). Later on, though, a group of rebels modify a large ship to function as a command ship of sorts with multiple consoles jury-rigged so that the ship would have an actual crew.
* Diesel and electric locomotives usually require just one operator. This would have meant firing countless thousands of firemen when steam engines were being retired, so the locomotive men's brotherhood lobbied for all heavy locomotives to carry a crew of two.
** Similarly, there was a lengthy industrial dispute in the UK in 2017 about a proposal to [[SeriousBusiness give train drivers control over automatic doors instead of the guard]].[[note]]"conductor" in US English.[[/note]]
* Uncommonly inverted by ''VideoGame/MetalFatigue,'' a HumongousMecha RTS developed by the late Psygnosis. The [[HumongousMecha Combots]] are controlled by a crew of several men, explicitly shown to consist of a team of at least three pilots. In spite of this, the Combots are also explicitly shown to be MotionCaptureMecha, at least for the primary pilot. However, the non-Combot vehicles, including missile cars, tanks, and hovertruck worker units, appear to be crewed a single individual due to a sheer lack of space--a complete 180 of the usual expectations in humongous mecha settings.
* Numerous vehicles in the Franchise/GIJoe action figure line. While many had extra places for gunners and other crew, some only had one. Notably, the franchise's first tank was like this, even though in the comic it was shown to have space for a driver and radioman.
* ''Tabletopgame/BattleTech'' normally has just one pilot (a [=MechWarrior=]) to control a [[HumongousMecha Battlemech]], albeit assisted by the mech's computer for movement and aiming. However, some models designed for [[FrontlineGeneral field commanders]] come with an additional seat and console for a radio operator. The disastrous [[ProudWarriorRace Clan Jade Falcon]] attempt to reintroduce the [[LostTechnology LosTech]] [[TransformingMecha land-air-mechs]] resulted in a mech with two cockpits - one for an Aerospace pilot, the other for a [=MechWarrior=] - which controlled the LAM's different movement modes. The bullheaded Clan warriors rarely cooperated.
* ''VideoGame/FarCry2'' has a bit more of a realistic take on this than other games. For land-based vehicles, the player has the usual button dedicated to switching between the driver's seat and the mounted gun, but there is actually an animation of the character climbing between the two positions rather than instantly teleporting between them when the player presses that button. For boats, the player instead has to manually move between the driver's seat and the gun because they're further apart[[note]]getting out of the driver's seat in this game has your character simply stand up from it, rather than dumping them right in the water five feet off to the side like other games[[/note]].
* ''Franchise/{{Halo}}'':
** While UNSC planes (space or otherwise) ''can'' be flown by one pilot, most of them do seem to operate with a full crew. It's mostly [[SuperSoldier Spartans]] with their advanced neural interfaces who can operate them solo, like when the Master Chief pilots a Pelican gunship in ''VideoGame/{{Halo 4}}''.
** Averted by most vehicles with a turret; for example, you can't operate the gun on a Warthog jeep and drive it at the same time. This is justified in that the gun controls are physically located in a different part of the vehicle.
