Continuity mistake: Kirk is talking to Scotty on his monitor, after they have finished talking Kirk goes to switch off the monitor by pressing the button just below it. If you watch very closely you will notice Mr Scotts image fades from the screen before Kirk even touches the button. (00:07:05)
Continuity mistake: Gary Seven is talking to his computer, we then switch to Kirk and Co and after a few moments with them we cut back to Gary Seven. Somehow in that time, while talking to his computer he changed his clothes. (00:13:40)
Continuity mistake: After Gary turns on the typewriter and tells Roberta to give her report but not with her fingers, she responds, "Well, how do you expect me to type, with my nose?" But the typewriter types, "How do you expect me to type, with my nose?" omitting the "Well." It didn't edit her question, because we see from the rest of the scene that it types absolutely every word she says until Gary turns it off. (00:17:45)
Continuity mistake: When Isis meows and enters the inner office, the door is open several inches and the lights inside the room are on. When Gary Seven follows her in a few moments later, the door has nearly closed itself and the lights inside are off. (00:20:25)
Continuity mistake: Isis is an all-black cat, but in a few shots, her "stunt double" with white paws can be spotted. The cat lying on the floor of the transporter room when Gary Seven beams aboard is a white-pawed double.
Continuity mistake: As Gary Seven beams in, Scotty's hair changes between shots.
Continuity mistake: Gary Seven pushes a pen holder over to open the doors. The pen wasn't returned to the upright position, but was up when Kirk came in.
Continuity mistake: When the computer opens and begins operation in Gary Seven's office, it's white. In the close up, it goes from white to purple when asking for identification. Afterwards, the color continues to change.
Continuity mistake: As Gary Seven starts to talk to the computer, it has a light gray exterior. When it first talks, the trim turns purple, then it's back to light gray.
Continuity mistake: The second time McCoy is shown in the Sickbay, he is first shown sitting and writing. A moment later, he's standing bent over the terminal.
Continuity mistake: To open the secret doors, Seven tilts one of the pen holders down to the top of the desk. After he's gone, Ms. Lincoln comes in looking for him, and the pen is upright without it having been pulled back up, unless it was supposed to reset itself.
Continuity mistake: The shots of the rocket Scotty cycles through are of different times. There is one shot of the rocket at the launch site, followed by one of the transport taking the rocket to the site.
Continuity mistake: As Kirk talks to Chekov on the screen, his hands are flat on the table, and there is a collection of data tapes in front of him. After the angle change, his hands are clasped on the table, the tapes have been replaced by a data pad, and Kirk appears to be frozen.
Chosen answer: If they're in orbit, they're being pulled along by the planet's gravity well, therefore, impulse engines would only be used for minor corrections and would be "on standby" while in orbit, but not active. (Like keeping your car idling without revving the engine and creating plumes of exhaust).
