Factual error: Throughout the show, skyscrapers are consistently shown. The height of buildings in Washington DC is restricted by the Height of Buildings Act of 1910, and there are no buildings taller than 13 stories.
Yankee White - S1-E1
Factual error: Air Force One landed in Wichita, Kansas. The local coroner claimed Jurisdiction for Wichita County. The city of Wichita, Kansas is in Sedgwick County, in southern Kansas. Wichita County, Kansas is in western Kansas, about 250 miles from the city of Wichita. (00:05:40)
Factual error: The episode takes place on the Destroyer DD 964 U.S.S. Paul F. Foster, but every time the ship is shown sailing past the camera you see the number 51 on the side. This is the number of the U.S.S. Arleigh Burke, a DDG not even the same class of ship. (00:11:15)
Factual error: In the yacht rescue scene the "American" crewed helicopter is actually an Australian crew. The rank on his shoulder shows an Australian Lieutenant Commander. (00:34:30)
Factual error: While the NCIS crew are working a crime scene, Ducky starts yet another parable about his past experiences, referring to the dating of an Indian skeleton by the caliber of the bullet, "a 40-75". He states that since he knew the year that the US Army used that caliber, he could accurately date the remains. Unfortunately for Ducky, the US Army never used a 40-75. It did, however authorize a contract for a 45-70 cartridge in 1873. (00:09:20)
Factual error: Special Agent Gibbs asks McGee how long Medical School takes in the UK, to which he answers 4 years. This is incorrect, because almost all aspiring doctors in the UK go through the Undergraduate Medicine route (MBBCh) which takes 5 years. When McGee performs a search on the computer, he enters "Medical Post Graduate" in the search criteria, which would be unlikely in real life. (00:24:27)
Factual error: Obviously written to make the story interesting, but Gibbs says that the first criminal caught by DNA was a Mafia don in Sicily. Well as anyone interested in forensics knows it was Colin Pitchfork in England.
Factual error: After Gerald gets back to NCIS HQ, he notes that he wasn't able to drive Ducky's Morgan; a stick. Abby brags about knowing how to drive a stick since she was ten. When asked what she drove that had stick, she answered, "Red '47 Ford half-ton with four on the floor and Bubba riding shotgun." When asked who Bubba was, she answered that he was the best coon dog in Jefferson Parish. If in fact Abby grew up in the city of New Orleans, as stated by McGee in the episode before, the dog would not have been the best coon dog in Jefferson Parish but Orleans Parish. No part of New Orleans is inside the Parish of Jefferson. If it was truly the best coon dog in Jefferson Parish then Abby would have lived in Metarie or Kenner, Louisiana, both of which are inside the parish limits of Jefferson Parish.
Factual error: Lieutenant Colonel Mann explains to the NCIS team that a "99 Toyota" is the only unaccounted for vehicle from the golf course bombing. The vehicle is a Toyota but is obviously a mid-80's Corolla, with the last production year being 1987, making it over a decade older than Mann claims. Additionally, she would not have know the year of the vehicle prior to the team running the plate, nor would she have pointlessly assumed its year. (00:32:06)
Factual error: The inspector is suffering from thallium poisoning. However, everyone is using various radiation detection methods to detect the thallium. Natural thallium is not radioactive. Of the artificial thallium, the only with a half-life long enough to last long enough to pose a problem is too weakly radioactive to be a significant hazard.
Factual error: When McGee is tracing the who sent the request for the polygraphs, the map bounces around the world. When he says Kurdistan, the map shows Armenia, and when it hits the Dominican Republic, McGee says Puerto Rico. (00:26:50)
Factual error: During the slow motion sequence in DC, landmarks from Los Angeles are in the background. (00:11:45)
Factual error: There is a big deal made about Gibbs giving Shepard one of his magazines in the study with La Granoille. It is implied that that magazine was used in the gun to kill La Granoille on his yacht. The magazine he gave her was for his department issued Sig Sauer P228, however, he was killed with a Glock 19. The magazines are not compatible.
Factual error: During the sequence where Bankston and Lee are supposed to make the dead drop of Domino, Adams Tavern, the location of the drop, is shown to be at 2177 Pimmit Drive in Woodbridge Va. The map that is showing the location is geographically correct, but "Pimmit Drive" is actually Horner Road. Also once the action leaves the bar, Lee and Bankston hijack a bus that reads "District Transit Authority". Since they are in Woodbridge, the bus service would be OmniLink. (00:30:20 - 00:38:15)
Deliverance - S6-E15
Factual error: It is constantly mentioned that the number found at the crime scene is Gibbs' military service number. The Marine Corps stopped using service numbers on Jan. 1, 1972 and since has only used Social Security numbers for identification.
Factual error: The commercial 747 landing in Washington from France is the president's plane Air Force One, not a regular passenger jet. It's actually reused footage from the film Air Force One.
Chosen answer: It is never stated, however she must have been there several years if she is on presidential detail.
