Narrator: This is one of the out-of-the-way places, the unvisited places, bleak, wasted, dying. This is a farmhouse, handmade, crude, a house without electricity or gas, a house untouched by progress. This is the woman who lives in the house, a woman who's been alone for many years, a strong, simple woman whose only problem up until this moment has been that of acquiring enough food to eat, a woman about to face terror which is even now coming at her from the Twilight Zone.
The Spaceman: Central Control...come in Central Control. Do you read me? Gresham is dead! Repeat, Gresham is dead! The ship's destroyed. Incredible race of giants here. Race of giants.

The invaders, who found out that a one-way ticket to the stars beyond has the ultimate price tag. And we have just seen it entered in a ledger that covers all the transactions of the universe, a bill stamped 'paid in full,' and to be found, on file, in the Twilight Zone.
NASA was not established until 1958, which is why the United States Air Force's logo was on the spaceship.
The miniature spaceship prop was the same one used in the classic 1956 film Forbidden Planet.
