Revealing mistake: Episode: Testimony of a Traitor (season 2): As the 'video' of Buck's former advocate/cohort begins, we see a disheveled man in uniform seated behind a desk in his bombed out office. The TV on his desk is an obvious late-70's model, and his video player is a vintage 1978 model. This show is supposed to be about the 25th Century, and the Treason video, based in 1987 - and Buck was an Air force commander - so you'd think this government officer friend would have more futuristic-looking technology in his office. (00:08:25 - 00:12:45)
Visible crew/equipment: VAMPIRE: The tip of the boom mic is visible for a few seconds. (00:09:05)
Factual error: Buck Rogers is supposed to be a Captain in the Air Force, but he is wearing Navy wings. In fact he is not even wearing Naval Aviator (pilot) wings, he is wearing Naval Flight Officer (navigator) wings.
Continuity mistake: In "Plot to Kill a City: Part 2", Kellogg is told the man was lying about the top button giving access, so he presses the bottom button, which goes dark. In the shot of them entering, the buttons have switched, with the top on dark.
Revealing mistake: In "The Plot to Kill a City (Part 1), before Buck is "levitated", you can see the black wires meant to lift him.
Factual error: In the narration intro Buck's 1987 spacecraft is called "Ranger 3". But the Ranger series spacecraft were unmanned lunar landers, and NASA never repeats project names to avoid confusion.
