Narrator: In the vernacular of space, this is T-Minus one hour, sixty minutes before a human being named Major Robert Gaines is lifted off from the Mother Earth and rocketed into the sky, farther and longer than any man ahead of him. Call this one of the first faltering steps of man to sever the umbilical cord of gravity and stretch out a fingertip toward an unknown. In a moment, we'll join this astronaut named Gaines and embark on an adventure, because the environs overhead--the stars, the sky, the infinitive space--are all part of a vast question mark known as the Twilight Zone.
This episode, as with all in Season 4, were an hour in running time. All episodes in Season 1-3 & 5 were only 30 minutes.
