This episode marks the death of Russell Keys (Steve Burton).
This episode takes place in October 1962, during the Cuban Missile Crisis.
(Owen Crawford and his son, Eric, are discussing Apollo 13)
Eric: Do you think our friends had anything to do with it?
Crawford: Between their preponderancy to intervene in our affairs, and the growing incompetence of NASA...I'd choose NASA.
(Eric smiles slightly)
Eric: If you were still in charge of the project, you'd use this as evidence of an imminent alien threat.
Crawford: (smiles) Probably.
