Rocket Continuity on I Dream Of Jeannie

I recently got rid of satellite TV and went with old school rabbit ears for reception. I've watched some re-runs on ME TV and Antenna TV.

Today's episode of I Dream Of Jeannie showed a Gemini Titan launch quickly followed by the orbit of an Apollo capsule with three astronauts. Captain Nelson then did a tethered space walk.

Obviously, historic continuity wasn't a priority.
But back then I wasn't watching I Dream of Jeannie for the space walks.
