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.
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".
The City on the Edge of Forever - S1-E29
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.
The City on the Edge of Forever - S1-E29
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.
The City on the Edge of Forever - S1-E29
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.
The City on the Edge of Forever - S1-E29
Corrected entry: After extinguishing the fire, Spock pulls a large vacuum tube out of the primitive computer power supply he's constructed on the bed. When the shot changes, the tube is back in place again. (00:30:00)
Correction: He took the phaser from transporter chief Kyle before beaming down.
So he did... I stand corrected.
