Factual error: In several episodes where Tony Nelson is in a space capsule and communicating with Cape Kennedy personnel via radio, he ends his calls by saying "Over and out." In radio communications, "Over" means "I am done talking. Please respond." "Out" means "I am done talking and I am ending this communication." The two words are used individually, never together.
Continuity mistake: Anthony is always referred to as Major Nelson, although he is wearing the insignia of a Lt. Colonel.
Suggested correction: Tony is wearing Major rank, which is the gold leaf. Lieutenant colonel is the silver leaf.
Halfway through the first season he is wearing a silver oak leaf. They repeatedly call him Major.
The first season was in black and white. How can you tell what color it was?
Continuity mistake: In the first ever episode Tony states that his mother is in Salt Lake City, implying this is where she lives. However in the episode where she visits Tony, she is from Bridgeport and then in the last few episodes of season five Tony talks about growing up in Ohio.
