Factual error: When Michael fills the tank with water (below the stock room), he then strips his clothes off, and slides down a pipe and into the water at the bottom of the tank. Since the water level was way above him, the pipe he slid down and the access to get there would have been flooded also. There was no water in the pipe he slid down, so for that area to be dry, it would have to be above the water line.
The Beautiful Day in the Neighborhood - S5-E4
Factual error: Near the end, the gang is using Luminol to check for blood on neighbourhood signs. Luminol won't work in broad daylight, they should have used a blue light filtering lens to enhance its visibility.
Noisy Edge - S1-E12
Factual error: In the beginning of the episode, Charlie is stating that "there is always a solution" and "if there's any limitation it's got to be in the mathematician, not the math". Unfortunately, according to Kurt Godel's incompleteness theorems, this is not true. Simply put, there are mathematical problems that cannot be proven/solved.
Factual error: The train car in which Elle and the other passengers are held hostage is supposed to be an Amtrak type long distance railroad car traveling from El Paso to Dallas, yet on the inside of the car we can see a large poster showing the Washington, DC Metro system map.
I Married a Mind Reader - S1-E11
Factual error: A nitpicking mistake, but on the set of "I Married a Mind Reader", the front door is a modern steel design. Back in the 60's, front doors were almost always wood (steel doors weren't available until the 1970's or 80's), and the window design would have been larger on a 1960's fan-window wooden door.
Factual error: When Rose is introduced to the entire team McGloin shakes her hand and says that he (respects or admires) anyone that has survived the POW school. She smiles, nods and walks away. McGloin then explains to the last remaining teammate that all NIOs attend the POW school and explains briefly what it is. First: It is the SERE school. Survival, Evasion, Resistance and Escape not really POW. Second: Not all, not even most, NIOs attend SERE school, just some.
Factual error: When she's giving the historical tour, Sarah talks about how the Puritans who settled in Point Pleasant faced hardships during their first winter there. But the first village at Point Pleasant was built in 1817, a century and a half after Puritans ceased to exist as a distinct group.
Factual error: Nancy takes her son Silas to an 'underground' doctor used by gang members following an attack by a biker gang. After she tries to negotiate a lower price due to the lack of anesthetics, the doctor says that he can get a second opinion at a hospital and order a $10,000 MRI if she would rather pay for that. However, an X-Ray is the first, less-expensive method used by emergency rooms and trauma centers to confirm a fracture. An MRI is typically only used to evaluate skull/brain-related injuries, but is a rarer utilized, expensive second option to evaluate a fracture that generates an unclear X-ray.
Factual error: You hear a recording of Earl's ancestor from the 1860s, but audio recording like that was not technologically possible at the time (especially for someone as obscure as him). (00:10:30)
Episode One - S2-E1
Factual error: During this episode, Vincent is remanded to prison for suspected murder. At one scene he is seen working on the wing. Remand prisoners are not expected or allowed to carry out work duties in British Prisons.
