Corrected entry: We see our heroes paralysed by the alien belt machines, we then cut to the intro movie. When we go back to them they are being disarmed by the female alien. She takes something from McCoy's hand, yet before the intro he had nothing in his hands.
New this month Correction: Rewinding more, you will find that there is an instrument in McCoy's hand, only concealed while wondering the arrived aliens.
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: When Plasus and two sentinels beam down to break up the fight near the mine, Plasus is on the end of the trio as they materialize. The camera angle changes as they step off the dais, and Plasus is suddenly in the middle.
Correction: When Plasus and the two sentinels are materializing on the landing pad, Plasus is between and behind the two sentinels (look at their feet in relation to the outer rim of the pad). The initial camera angle makes it a bit difficult to see, but the men are in fact positioned consistently during and after transport.
Corrected entry: Spock says they've only managed to punch holes in the force field large enough to fire through. But when the Enterprise fires, the force field (in the shape of Apollo's hand) is no longer there at all.
Correction: When the Enterprise fires on the temple, the force field IS visible. However, as they continue to fire and damage the power source, the force field starts to fade and flicker in and out, until it is gone.
Corrected entry: Spock wants Uhura to keep her eyes on the monitor every moment. (One fluctuation and Scott could die.) But he calls her name, making her turn away from the monitor and look at him, in order to tell her not to take her eyes off it.
Correction: Spock only gives her the instructions after Scott opened the access plate. Prior to that he gave no instructions for her to not take her eyes off the readings. Once Scott inserted the probe is when the magnetic readings needed to be monitored, calling Uhura's name and having her take her eyes off the monitor at that moment caused no danger (or plot hole error).
Corrected entry: When Fox and his assistant beam down, the area they are in surrounded by a matte painting, used to extend the feel of the alien world.
Correction: How is this a mistake? Using matte paintings is a common technique used since the earliest days of cinema. There are many other examples throughout the series where they are used.
Corrected entry: In the sickbay near the end, Diana Muldaur got her line wrong, resulting in this contradictory dialogue: Kirk: "He'll die. But that's what you want, isn't it?" Miranda: "That's a lie!" Kirk: "Oh yes it is - you want him to die." Miranda's line was supposed to be, "That's not true," with Kirk's "Yes it is" contradicting her. As it stands, she claims it's a lie, and Kirk replies "Yes it is."
Correction: Kirk's reply of "yes it is" refers back to his statement of what Miranda wants - "that's what you want...yes it is, you want him to die". He's continuing his train of thought, not replying to her statement.
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.
Correction: This is not a plot hole. It is your judgment that the technology should work this way.
Corrected entry: Spock has been known to say that Vulcans don't lie. But in this episode, he backed up McCoy who was trying to spare Kirk's feelings. When asked by Kirk about the final taped orders he left them, Spock said that "The crisis was upon us and passed so quickly there wasn't time to view the tape." A bald faced lie.
Correction: Spock says "the crisis passed so quickly," and then trails off. He never says they didn't watch it.
Corrected entry: When McCoy is working on putting Spock's brain back it is obvious that his arms are too high up to be doing anything other than fiddling about with Mr Nimoys forehead.
Correction: Of course, the good Doctor would not be fiddling with Spock's forehead using his hands. He'd be manipulating mechanical servos (Waldos) or something analogous, since reconnecting neurons would require microscopic instruments and likely nanotechnology.
Corrected entry: At the end of the episode, 7 people beam back up to the ship, which should be impossible since the transporter only had 6 pads.
Correction: EACH transporter has 6 pads. Enterprise has more than one transporter (at least 4, I believe), so they can beam up 7 people, it's just that one will end up in a different transporter room.
Corrected entry: The landing party is out of contact with the Enterprise for two days because of the missing communicators. Wouldn't the Enterprise notice at some point and beam down some more, or make some other attempt to contact Kirk & Co.?
Correction: Before Kirk and co. loses their communicators, Kirk contacts the Enterprise and says that there should be no attempt to come down for fear of spreading the virus. The proof is they beam something down to Bones to help manufacture a vaccine.
Corrected entry: If the Enterprise made sure everything was corrected to just before they went back in time (before actually going back to their own future) then there should have been no reason for Kirk and Sulu to recover the audio and video evidence of their arrival in the first place, since they made sure they were never there.
Correction: They were unsure whether their sling shot experiment would work.
Corrected entry: The outcome of the court martial is already known before it happens. Since the captain's log is recorded after a mission giving a detail of what had taken place before the log was recorded, Kirk would not have been able to record his own log (as Captain) if he had been found guilty during the trial.
Correction: The outcome of the court martial is known to the viewers, of course. If Captain Kirk had been convicted, there would be no more episodes of the show. The point of the episode is to reveal the details of how he was acquitted, as they unfolded, and the Captain's Log is added later as a narrative framing device. This cannot be considered a mistake.
Corrected entry: Since Kirk has to be on the Enterprise to record his Captain's log (after the events of the episode), we know he and Spock are successful in repairing the timeline since Kirk is heard making his log entry just before he and Spock go back to the past.
Correction: He could make the log entry into a tricorder to be uploaded to the ship's log once he made it back.
Corrected entry: If McCoy changed the future history of Earth that causes the Enterprise not to exist, then the landing party and equipment should have ceased to exist as well.
Correction: It's said at the beginning that the Guardian is at the center of a time distortion. That distortion could be protecting them.
Corrected entry: Captain Christopher is beamed out of his plane while sitting down, yet he materializes on the transporter pad standing up.
Correction: This happens in most episodes of all Star Trek series where someone is beamed aboard while in a seated position, often enough that it seems to be a standard feature of the transporter that people materialize in a standing position.
Corrected entry: When Spock tries and fails to beam down to the the planet, Kirk claimed to have ordered Spock to stay in sickbay, yet he never ordered it: he simply requested Spock to stay in sickbay. There is a difference between a request and an order.
Correction: In most branches of the military, a superior officer "asking" you to do something is easily considered an order.
Corrected entry: About 19 minutes into the episode, Scotty gives the altitude of the person Kirk and Spock are looking for as approximately 30 meters (approx 98 feet) using accurate Enterprise equipment up from where they are standing on the street. They go to apartment 12B which would be the 12 floor. The stories in the apartment build would have to be slightly over 8 feet high each for it to be the 12th floor. Apartment building stories are at least 10-12 feet each. They should have come out on at most the 9th floor.
Correction: First it was approximately 30 meters, as in an estimate. Round it up to 100 feet, 10 feet per floor, makes 120 feet. An approximation within 20 feet is not unreasonable. Thirty five meters may have been a better approximation to state, but 30 is not an inordinate amount off.
Corrected entry: Kirk and Spock are thrown into a prison on planet Organia by the Klingons. The Organians, however, are a peaceful community where prisons make no sense.
Correction: The Organians faked their entire civilization, including both their own appearance, culture and buildings. As it is all placed there to fool visitors, a jail is not out of place at all, but helps maintain the masquerade.
