Storyline

When the Enterprise is flung back in time while trying to escape the gravitational pull of a black star, they find themselves in orbit around a 1960's Earth. When they are seen by a U.S. Air Force pilot, they beam him aboard but then face the dilemma of what to do with him as he learns more and more about the future. They have to review their initial decision to just keep him when historical records show that his yet-to-be-born son will lead Earth's first successful mission to probe Saturn. Spock devises a plan to do so while also erasing any memory of recent events. Written by garykmcd

Trivia

The music played as Christopher observes the ears on Spock, heard in its entirety in Star Trek: The City on the Edge of Forever (1967), was written by composer Joseph Mullendore during his scoring for Star Trek: The Conscience of the King (1966), but it went unused at that time. It is an uptempo version of the closing theme for the show. Mullendore had also arranged the "lounge" version of the theme for the same episode, also heard in Star Trek: Court Martial (1967).

Goofs

Spock informs Kirk that the Enterprise has arrived at Earth because it was headed in that general direction when they ship encountered the black star. However, according to Kirk's log entry the Enterprise broke away from the star by going in reverse. Therefore, the Enterprise was moving in the opposite direction from Earth when it went back in time. See more »

Quotes

[first lines]
Technician Webb: Captain?
Air Force Captain: What is it, Webb?
Technician Webb: A blip, sir. Just came on the screen.
Air Force Captain: How do you read it?
Technician Webb: Aircraft of some sort. By the size of it and the speed, it's not one of ours, sir. Doesn't even read like anything I've ever seen.
Air Force Captain: What was the approach?
Technician Webb: None, sir. It was just there, like it fell out of the sky or something.

Things Wrap Up a Little Too Nicely
27 April 2014 | by See all my reviews

The challenge comes when the gang travels into the past. Going through some time warp, the Enterprise is seen in the sky in the U. S. in the 1960's. Unfortunately, a fighter pilot tails them when when they attach a tractor beam, it tears the plane apart. They are able to beam the pilot on to the ship, but now more trouble follows. He, of course, is part of the past and anything he says or does can tear apart the fabric of time. It could lead to dire consequences. What to do. The man has a family and is a sympathetic character, but he is also military all the way and says he will tell everything he has experienced. The crew must also go down to earth and steal some computer reels to cover things up and again are forced to beam another man, a sergeant of security, onto the ship. It seems hopeless but the old scientific realities of the warp enter in. There is a solution, though if one thinks too much, it's awfully convenient. This is the curse of the television series in that we know these same people are going to appear next week. It's still a sort of charming episode with some good plot twists.
