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)
Factual error: George Wigg MP wears an RAF tie. Wigg served in the Royal Tank Corps and the Army Educational Corps, but he was never in the RAF. Few men would wear a regimental tie to which they weren't entitled, least of all someone in the public eye, where it would be immediately picked up and ridiculed. Especially given this is set only 17 years after the war (and only just after compulsory National Service ended) at a time when most men were entitled to wear some sort of regimental tie and recognised fellow veterans by the design of their tie.
Audio problem: The zombie chasing the man gets tangled on a wire fence and gets shot in the head. When the bullet impacts his skull he makes a grunting pain noise just like everybody else who gets shots in movies makes the same grunt. First of all zombies don't feel, so how can he express pain, and secondly when people get shot and die they don't grunt, they drop dead. (00:09:30 - 00:10:00)
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.
Character mistake: When Harlan Edwards collapses and Dr. Arcane tells them to clear his airway, one of the other doctors addresses her as "Dr. Cane."
Plot hole: The captain's wife tells him that she's taking his daughter with her, not giving him a chance to even say goodbye. During the episode it turns out that she's angry because he missed lunch with them, and when the Metal Wu texts the boss, it also turns out that all this just happens at 1:11 AM! It does not make much sense: she waited over 12 hours to complain to her husband, and she's driving her kid in the middle of the night.
Factual error: When Jane is putting up the lost poster, the number to call is 1-800-saw-him. However, this is only a 6-digit phone number when it needs to be 7-digits (not including the 1-800 part).
Character mistake: In Season 5, Episode 4 ("The Heart Attack Boys"), Abishola twice gives Christina an injection without swabbing her skin with alcohol. Abishola is an RN and would never make that mistake.
Factual error: An FBI briefer is talking about the hijacking of a passenger airliner. He calls it Flight 6175. The airplane has 6175 stenciled on the nose. Those are usually the last four digits of the airplane serial number, used by maintenance and dispatchers to designate a particular aircraft. It is not the flight number of any given trip. (00:04:45)
Factual error: Season 1 Episode 1 Arrival - Doctor Jaax is a Lt. Col. in the US Army. Her BDU blouse has a US flag on the right sleeve. The time period of the show is 1988, as there is a doctor wearing a Dukakis T-shirt. The US Army didn't have a US flag on the BDU uniform until 2005. (00:11:20)
Continuity mistake: Captain Dobbins has her Garrison cover tucked under the belt of her uniform overcoat with her rank insignia not displayed. In the next shots, the USMC emblem is displayed on her Garrison cover and rank insignia is displayed again. (00:25:05)
Visible crew/equipment: When Michael Fay (1st Vampire ground zero) enters the cabin to escape the police, the film crew can be seen through the porch railing at the bottom right of the screen. (00:40:53 - 00:49:47)
Character mistake: At the police station when Damien Asante is reading the information on the computer about the hit and run, he says "On February 25, 2015 Christy Markus and her son were struck by a car. The driver kept going." If you look at the computer screen, the date of incident says February 25, 2018. (00:30:00)
The Graveyard of What Might Be - S1-E2
Continuity mistake: As the scenes quickly cut, Maggie's hands switch positions many times as she holds her umbrella while talking to Vic.
Pride Parade - S5-E3
Factual error: Nandor manages to fly up to space, then loses control and falls back to earth in a fireball as he reenters the atmosphere. But objects reentering the atmosphere only get hot because they're generally travelling at immense speeds, 7-12 kilometers per second. Nandor just floated straight up, then falls straight back down. When Felix Baumgartner parachuted from the edge of space his maximum speed was about 1,300 km/h, and he didn't catch fire.
Continuity mistake: When Nick's mom tells him to show Gypsy around she takes the cigarette away from her lips. A shot later it's back in.
Other mistake: A Mexican pilot based in Ensenada is interviewed. He owns a 1983 Cessna 172 aircraft. When they show it in the air, it is a 2005 Cessna 182 based in San Antonio per the FAA database. A US registry aircraft would not be based in Mexico, owned by a Mexican pilot. (00:11:20)
Welcome to Hotel del Luna - S1-E1
Continuity mistake: Man-wol takes out her sword and points it at the old lady. In a close-up of the sword, we can see it is pressed against the old lady's neck. But in the next shot, it is a few inches away from her neck. (00:05:22)
