Star Trek episode "The City on the Edge of Forever" airs 1967

The twenty-eighth episode of the first season of Star Trek (the original series) The City on the Edge of Forever, first aired April 6. 1967.  Anomalous waves emanating from a strange planet wreaks havoc on the Enterprise, and causes Dr. McCoy to inject himself with a dangerous drug, resulting in psychotic episodes.  In his crazed state, he beams down to the planet below.

Captain Kirk, Mr. Spock, Lieutenant Uhura and a security beam down after him.  They find the the Guardian of Forever, a time portal showing Earth's past events in fast time.  Bones jumps through the portal and changes the past.  Kirk, Spock, and Uhura realize they are trapped, since the Enterprise no longer exists.

Kirk and Spock jump through the portal to locate McCoy before he can do the damage he caused to the current time line.

It's considered by fans to be the best episode of the entire series.  The final line is uttered by Kirk when he says "Let's get the hell out of here."

Also, Joan Collins stars as Edith Keeler.
