Factual error: Henry states that the car bumper of an 2007 'XJ' is a certain height off the ground and led to a particular injury to a dead person. He claims he knows this because he is a Jaguar enthusiast. He then points to a photograph of the 'New York Kids' in a pre-2002 Jaguar XKR as 'circumstantial evidence' that it was this car that caused the injury. A Jaguar enthusiast would never mistake an XKR for an XJ.
Continuity mistake: When Molly is in space, alone, a man she knew is on The Other Side of a door that has a circular window in it. The man uses his finger to draw the words "HELP ME." When we first see the words, they are legible and about a third of the way below the top of the window, but the next time the words are much higher up and hard to read, and the third time they are now back to the original place.
Crystal Blue Persuasion - S3-E15
Factual error: When Frank, Olga and he rest of the Back Step Team meet Commander (a Navy O-5 Rank) William Streck, he is dressed in a U.S. Air Force Uniform with the rank of Colonel (O-6).
A Single Piece Was Lost - S1-E10
Visible crew/equipment: When the Gruenaks attack the Scientist a puppeteer is visible to the right of one of the Gruenaks, just before it grabs the bird cage and throws it onto the Scientist's head. (00:28:18)
Plot hole: White Base and the interior of Luna II withstand without a scratch the explosion of the thermonuclear reactor from the Magellan from just a few meters, while the blast literally vaporizes the Zaku far away from the entrance and threatens to damage the Musai, hundreds of meters away.
The Two Deaths of Jamie B. - S2-E4
Revealing mistake: When Naomi shows Kirsten the money, you can tell it's fake. Not only are the serial numbers all the same, you can read "this note is not real it is to be used for motion pictures."
Here There Be Dragons - S2-E11
Visible crew/equipment: When Prax leads the group to where Dr. Strickland took Mei, just as they reach the door the two green and yellow T-marks are visible on the floor. (00:02:30)
Continuity mistake: When Miles jumps off the ferry to swim ashore, the camera view is from the ferry: he jumps into quiet, fairly level water, yet the camera recedes from him (he jumped off the back of the boat as the camera continues moving with the boat). The angle changes and we see the wake of the boat - but it's not what he jumped into.
Other mistake: The URL seen on Siobhan's laptop (https://internet-search.comm7986/index.html) is obviously a fake URL.
Us vs. Them - S2-E2
Factual error: We see Liam's driver's license. It says he's from Rhode Island, but the license looks nothing like RI's. It's issued by the State Motor Vehicle Commission, but RI does not have an MVC (only New Jersey does). And the expiration date is always the same as the holder's birthday, but here we see it's 2 days after his birthday.
The Book of Occupation: Chapter Five: Requiem for Tavon - S3-E5
Visible crew/equipment: Right before Anissa and Tavon are attacked by Khalil, the shadow of a camera can be seen on the ground in the bottom right corner of the screen as they approach the path.
Continuity mistake: When Captain Bragg orders her troops to move in on the people in the square, GS-8 is standing behind her, despite the droid having fled the scene just two shots earlier after Senator Singh's arrest. (00:02:58)
Pathfinder - S2-E4
Factual error: Ed and Gordo are both flying NASA T-38 Talon aircraft from Houston to the Cape. NASA is a civilian space agency, and all of its planes are registered as civilian aircraft. But Ed's T-38 is shown in one shot as having US Air Force registration.
Monkey Fun - S2-E13
Other mistake: Season 2 episode 13 "Monkey Fun": Just before the enlarged Titano appears at the zoo, there is a family watching normal-sized monkeys in a cage. The family father (farthest on the right) has a drawing disorder with his eyes: their pupils look up and down, respectively, giving him a rather goofy expression.
Continuity mistake: When Simon Carver and David are speaking in Carver's office, Carver's hands instantly change positions form being spread out on his desk to clasped as the camera shots switch.
Emergency Marineville - S1-E11
Continuity mistake: When the second group of Spearhead jets take off from Marineville there are only two jets, but in the next shot you can see three jets, and in the next shot there are two again.
The Mind of Simon Foster - S3-E23
Continuity mistake: When the pawnbroker closes his metal gate, he's facing the wire mesh. When the shot cuts, he's instantly facing away from it. (00:10:15)
Triumvirate of Terror! - S3-E8
Continuity mistake: After revealing himself to Wonder Woman, Joker rips of his cross-dress disguise. The two halves land on the ground on both sides of him. But then when he subdues Wonder Woman with his Joker gas, he is standing in the same spot, approximately, and the torn clothing is now gone. (00:12:00)
Revealing mistake: Mr Knight shoots Suzie Boreton - after the muzzle flashes and sounds stop the bolt of his MK14 EBR continues to move back and forth as if it's still firing. (00:30:30)
Audio problem: While Pickles is sniffing the ground, she asks Bob "Did you know vomit tastes bad?", but her lips don't match what she is saying.
