  • Quotes (18)

    • Uhura: Mr. Spock! Are you all right? Spock: Yes. I believe no permanent damage was done. Uhura: What happened? Spock: The occipital area of my head seems to have impacted with the arm of the chair. Uhura: No, Mr. Spock. I meant what happened to us?

    • Kirk: Mr. Sulu, if I had wanted a Russian history lesson I'd have brought along Mr. Chekov.

    • Rahda: Hmm. A positional change. It doesn't make any sense. But somehow I'd say that in a flash we've been knocked 1,000 light-years away from where we were. Spock: 990.7 light-years to be exact, Lieutenant. Scotty: But that's not possible. Nothing can do that. Spock: Mr. Scott, since we are here, your statement is not only illogical but also unworthy of refutation.

    • Spock: Can you give me warp 8? Scotty: Aye, sir. And maybe a wee bit more. I'll sit on the warp engines myself and nurse them. Spock: That position, Mr. Scott, would be not only unavailing, but also... undignified.

    • Rahda: We're holding warp 8.4, sir. If we can maintain it, our estimated time of arrival is 11 and 1/2 solar hours. Spock: 11.337 hours, Lieutenant. I wish you would be more precise.

    Notes (3)

    • Dr. M'Benga makes his second and last appearance. He was previously seen as the backup physician with special knowledge of Vulcans in "A Private Little War."

    • A phaser set to disintegrate apparently generates a temperature of 8,000 degrees Centigrade (just under 14,500 degrees Farenheit). By comparison, the surface temperature of the Sun (based on blackbody radiation theory) is around 5,500 degrees Centigrade (note that the core temperature is far higher -- well into the millions of degrees).

    • D.C. Fontana wrote the story for this episode under the pseudonymn Michael Richards.

    Trivia (12)

    • Trivia: This episode establishes that people can move and are still aware of their surroundings while in the midst of being dematerialized by the transporter. This concept would be continued in the following movies and series, such as in Wrath of Khan in which Kirk manages to continue a conversation with Lt. Saavik while beaming; and the Next Generation episode "Realm of Fear" in which Lt. Barclay becomes aware of beings existing within the transporter beam.

    • The Enterprise is able to travel 1000 light years to retrieve the Captain in approximately 12 hours. This is a much faster speed than we have seen in previous episodes. It would make it possible for the Enterprise to reach Andromeda in a year and a half, whereas in "By Any Other Name" such a journey would have taken thousands of years.

    • When Kirk and the crew land on the planet and an earthquake hits, the stones bounce and roll around like the lightweight objects they are.

    • Trivia: While the landing party discusses the fact that the tricorder cannot detect Losira, Sulu suggests that she might be a silicon based lifeform like the one encountered on Janus VI. He is referring to the Horta from "Devil in the Dark."

    • When Losira sabotages the Enterprise engines, Scotty states "This thing is going to blow up, and there's nothing in the universe that can stop it". However, a few minutes later, Spock figures out a solution to the problem.
