Space Seed - S1-E23
Corrected entry: During Kirk's fight with Khan in engineering, he pulls a white rod from a console and uses it to subdue Khan. The rod is very light, and several times when Kirk hits Khan with it, Khan shows no reaction at all.
The Return of the Archons - S1-E22
Corrected entry: As Kirk and co. carries O'Neil out of the alley, the supposedly unconscious woman in the black dress moves her foot out of the way as they pass. (00:18:05)
Correction: The unconscious woman's foot did move, but not on her own - other cast members' feet caught and moved hers as they were exiting the scene.
This is incorrect. While the actors DO move her foot, once they've gone, she can be seen repositioning it herself.
Corrected entry: The sword Spock is carrying disappears between leaving the cell and the group exiting down the corridor. No one else in the shot appears to have taken possession of it. (00:21:50)
Requiem for Methuselah - S3-E19
Corrected entry: Mr. Flint grabs the Enterprise out of orbit and transfers it onto the table. We assume, because the ship is small, it doesn't weigh much. However, Star Trek canon states the Enterprise weighs 190,000 metric tons, size not withstanding. There's no way that small table could hold such a massive weight.
Correction: We have no idea of how the technology he uses works. If he can shrink the ships down to a miniature size and instantly put everyone in suspended animation, there's no telling if he can alter the weight as well. Not to mention the fact that if he has such advanced technology, he could have a table that's able to bear the weight.
The old "Fantastic Voyage" problem. There are only 2 ways to make something shrink - either you reduce the physical size, and the mass stays the same, in which case the Enterprise on the table now has neutron-star level gravitational pull, OR you delete 99% of the atoms and keep 1 out of every 100 (sampling), like reducing a bitmap image in size. And just like that image, when the Enterprise went back up to full scale, everything would be "chunky."
The City on the Edge of Forever - S1-E29
Corrected entry: On the ship, McCoy gets injected, runs down to the Transporter, and beams to the planet. On the surface, he has a phaser, when he didn't have one when he beamed down.
Correction: He took the phaser from transporter chief Kyle before beaming down.
So he did... I stand corrected.
The Gamesters of Triskelion - S2-E16
Corrected entry: As Shana watches Kirk, Uhura, and Chekhov disappear, when the camera is in a close up on her face, the vertical seam where two wall sections meet is visible.
Correction: It is more likely to be one of the numerous torch poles surrounding the arena.
This Side of Paradise - S1-E25
Corrected entry: Spock is wearing his normal blue uniform when shot with the "happy spores" from the strange plant. The next scene is with Kirk inquiring about Spock's location to which he is told nobody has seen him. Spock somehow manages to find some green overalls out in the meadows when we switch back to him. (00:17:40)
Correction: Remember, Leila took Spock to that location for the express reason of having him infected. She likely brought civilian clothes for him, knowing he would no longer want to wear his uniform.
Corrected entry: In a very strange coincidence, a little more than seven minutes into this episode, which aired March 29, 1968, Spock states there will be a major assassination today. Six days after the original airing, Martin Luther King was assassinated in Memphis on April 4, 1968.
Corrected entry: Glasses worn by a transporter crew member disappear as Pike and crew are beamed down. (00:37:06)
Correction: 1) There is plenty of time for him to remove them while the landing party steps onto the platform. 2) He is wearing them while making notes on a pad. Obviously, he only needs them for reading/writing.
Corrected entry: While Lieutenant Galloway is coming into sickbay and dies there is a window in the hallway with window blinds, and through this window you can see some of the production staff in regular clothing talking.
Correction: The "production staff" is dressed in Star Fleet uniforms. They are not just standing around talking but working with something. There are even flashing lights in the background. The window is looking into a medical lab. Besides, the supposed error defies reason. Why would they build a window into a set and put nothing behind it?
Tomorrow is Yesterday - S1-E20
Corrected entry: When the Enterprise is slingshotting its way back to the "present" it uses the computer to deposit the two men at different times, The Enterprise is traveling backwards in time, so will logically meet the time when the guard was beamed up first, not after Christopher is returned to his cockpit. So the order is wrong. Should be guard then Christopher, not Christopher then guard. (00:43:15)
Correction: They are moving backwards in time as they approach the sun, but after the slingshot breakaway they are moving rapidly forward in time. Spock even says the chronometer is moving forward again, and then Kirk asks if they have the exact chronometer reading before redepositing Captain Christopher and the Sergeant. So the order depicted in the episode is actually the correct order.
Where No Man Has Gone Before - S1-E4
Corrected entry: If the point was to repair the ship, and maroon Gary Mitchell, then why have Lee Kelso wire a destruct button, thereby threatening Gary's life and placing Lee's life in jeopardy when Gary's powers could overcome him? If they were afraid Gary would become too powerful left on his own, then marooning him should not have been an option.
Correction: It's explained in the episode that the plan is to maroon Mitchell there, but Kirk wants a backup in case they aren't able to escape or Mitchell becomes too powerful.
Corrected entry: After Kirk and Spock's identities are revealed, they are taken to a prison cell. However, the Organians are a race of pacifists who abhor any act of violence - this should presumably include the act of incarceration. As such, there should be no prisons on Organia. Moreover, the Klingons are not stone masons; the prison cell shown in the episode is architecturally consistent with the other buildings on the planet so it was not constructed by Klingons (especially so quickly).
Correction: This is purely speculation. Being pacifists doesn't preclude them from having a jail cell, especially since the entire town was created for the benefit of outsiders.
Corrected entry: Ben's plan is absurd, hiding and pretending to be dead in a ship of over 400. Eventually Ben has to eat or use the bathroom, someone would see him.
Correction: His plan is absurd, which leads to him being discovered, exactly as you say. He's shown to be deranged, if not insane, so this isn't a plot hole, it's a plot point.
Tomorrow is Yesterday - S1-E20
Corrected entry: When the tractor beam crushes the fighter jet, Spock asks captain Kirk, "do you want me to turn off the tractor beam?" Why would Spock ask a stupid question like this?
Corrected entry: Scotty is cutting through the bulkhead to get to the controls to open the door to get to engineering, but considering the time left, why not just blast through the door itself?
Corrected entry: When Spock takes Captain Pike out of the briefing room, Pike appears, via the viewscreen, on Talos IV in the very next shot. There is no possible way Spock could have gotten Pike to the transporter room that fast.
Correction: Not a mistake. Pike's appearance on the screen is of his younger, uninjured self - obviously one of the Talosians' illusions. So they "jumped the gun" a bit by showing him on the planet before his actual arrival, but this image is only for illustration to the people viewing, so it doesn't matter.
The City on the Edge of Forever - S1-E29
Corrected entry: In the credits, Joan Collins' character is named "Sister Edith Keeler." But her character is engaging in a romantic/sexual relationship with Kirk. He says he has "ulterior motives" towards her which she reacts to playfully and kisses him. Not appropriate behaviour for a sister, particularly in the time and place the episode is set.
Correction: Edith Keeler wasn't a nun. She was a social worker, and thus, nothing she did would be considered inappropriate. She did work at the mission soup kitchen, where they would have called all women "sisters" just like they might call the men "brothers".
Corrected entry: Just how the Troglyte spy manages to leap over one of the cloud city's balconies to his death is a bit puzzling. Stratos City is held aloft by huge anti-gravity generators. An anti-grav field should, sensibly, extend far enough past the balcony railings to keep people from falling off. Surely the self-obsessed Stratos dwellers would extend that field, since they want to protect their own skins above all else. (00:07:05 - 00:11:30)
Correction: This is not a plot hole. It is your judgment that the technology should work this way.
Corrected entry: Jeffrey Hunter, who played Jesus in King of Kings, was the original captain of the USS Enterprise, namely Christopher Pike.
Correction: This is hardly trivia. He played Pike in the rejected pilot, which was subsequently released (and used in flashbacks), so anyone watching would know this.
Correction: First off, we do not know how "heavy" the rod is, but could have been handled easily by Kirk due to adrenaline from the fight. Second, in context of the story of Khan and his people being genetically engineered super humans, Khan would be able to absorb some of the blows Kirk delivers to him.
