Continuity mistake: Season 7, episode 2, "The Mommy Problem." At the end of the episode, when Matt Santos is approaching his fighter jet, the number "15" is on the left part of the jet's nose. Later, when the jet is taxiing towards take-off, the number changes to "01".
Factual error: At the end of the episode, the pilot says their runway has been changed to "runway 39." Runway headings are multiples of 10° from 01 up to 36. There cannot be a "runway 39."
Factual error: When the president signs Toby's Presidential Pardon you can see his name listed as "Toby." However such a document would refer to someone by their full, legal name. In this case the document should say "Tobias" not Toby, which, although commonly used throughout the series, is still only a nickname.
Character mistake: Will's tax demonstration to his volunteer staffers is incorrect. He applies the various tax rates to the entirety of each salary range. The person who makes $150K and is in the 36% rate...in his example he has them paying 36% on their entire salary, not just the portion of it that puts them ahead of the next lower tax rate. If the tax rate jumped to 70% at income of $1M, and a person earned $1,050,000, they wouldn't be paying the 70% rate on all $1,050,000 of their income, only the last $50,000 of it. Will's example makes it look like they would be.
Inauguration: Over There - S4-E15
Continuity mistake: Bartlett is in the executive office in the residence watching four TVs at once. He hears a line in the black and white movie, a second later he rewinds it to hear the line again - he rewinds way too much and for too long, but once he stops the tape, it plays the line he wanted to hear again right away. He went too far back (for visual effect) than what in reality it would have taken.
Continuity mistake: As Margaret enters Leo's office, the bottom corner of her ID tag is tucked into the sweater's button area. It remains this way when she stops walking. The camera reverses angle for a moment, yet we can still see she isn't moving. But the angle changes back and suddenly the ID hangs freely, dead center, over the buttons. Moments later, as she turns to leave, it's again tucked in. (00:12:10)
What Kind of Day Has It Been? - S1-E22
Other mistake: I call this one an "Escher Mistake". As Donna and Josh near the end of their chat about the chair that needs repairs, they pass an office door on their left (Nancy McNally's office) just before going through another doorway. The camera that follows them passes "through" a solid wall and emerges in an office, facing a hall and stairwell as Josh and Donna enter from our left as if this has all been a continuous shot. But the camera-through-the-wall moment is actually a cut so that the actors can be on a totally different part of the set. This would be fine, except the staircase they are about to turn left to and climb only rises up about 3 feet, then the user turns left again and heads to our left - but that sends the user into McNally's office, and does so 3 feet off the floor, yet they are seen entering the press room instead. (00:11:50)
Revealing mistake: Oliver Babish's office has windows in a location it can not possibly have them. Jed and Leo are in continuous conversation as they leave the 'normal' West Wing set at the end of a hall (See http://www.whitehousemuseum.org/special/wwtv.htm where the words 'Press Briefing Room' are - that's where they turn to their right). They walk a few steps then turn right again and ahead of them is Babish's office, with windows straight ahead. If this had been a single continuous set, Babish's office would be located in the stair area to the left of the press briefing room, and the windows would offer a view of the hallway that runs between the lower corners of Leo and C.J.'s offices (seen at 3:36), not the outside world. (00:03:30)
In the Shadow of Two Gunmen: Part I - S2-E1
Revealing mistake: When the Secret Service drags Hoynes out of the White House lobby, they exit through the main entrance, doors that are shown in episodes before and after as leading directly outside. But instead of seeing a convincing night exterior this time, the flashing cameras reveal nothing but a blue studio backdrop is out there. (00:06:30)
And It's Surely to Their Credit - S2-E5
Continuity mistake: When Ainsley Hayes and Lionel Tribbey are talking in her office, the bottled water moves from being to the right of the framed picture on her desk in the shots over her shoulder to being behind the picture in the shots of her desk from the front. (00:21:40 - 00:22:30)
Factual error: In the situation room, Colonel Chase informs Leo that a CH-47 Seahawk helicopter was dispatched from the USS Monterey. Problem is, the CH-47 is called "Chinook" while the SH-60 is the Seahawk (of which the USS Monterey carries two). See: http://picasaweb.google.com/agbeko.Dzamesi/Aircraft/photo5029495094968996146 for photo of an SH-60B Seahawk landing on the USS Monterey. (00:11:20)
H. Con-172 - S3-E11
Character mistake: Bartlet tells Leo that Jackson's censure was expunged in 1836, but it was actually January, 1837. (00:41:10)
Factual error: Will Bailey (son of the Supreme Commander, NATO Allied Forces, Europe, and an Air Force officer himself) states the fighter jet alongside Air Force One is an "F-16 Falcon", but it is actually an F-15 Eagle. (00:13:05)
The Lame Duck Congress - S2-E6
Plot hole: In order to allow time for a lengthy scene conversing while walking, actor John Spencer is sent on a ridiculous course through the West Wing. See the floor plan at http://www.whitehousemuseum.org/west-wing/west-wing-TV.jpg to follow along. He's first spotted leaving Margaret's area (blank space located just up and left of his "Chief of Staff" office on the plan). The handheld camera is in the Roosevelt room at this point. He turns right, traveling between his office and the Roosevelt room, meeting Donna along this hall. They make two slight left turns, then a hard left, entering the Roosevelt room (at the top/right corner's diagonal door). They walk the length of the room, turn left (down) and Leo drops some of the paperwork he carries onto the end of the table. They then exit the room (bottom left door) which is right outside the doorway where Leo started the scene. Leo isn't wandering. He's quite deliberate in his choices, yet if he'd simply walked straight ahead 6 or so steps from where he started, he'd have been where he dropped the papers. (00:16:50)
Continuity mistake: Josh and Amy are in a restaurant having breakfast and talking about the vote - the sugar dispenser can be seen next to some yellow flowers. In subsequent shots the flowers are still there but the dispenser has disappeared, even though no one touched it.
NSF Thurmont - S6-E1
Continuity mistake: When Donna is writing on a pad to Josh when awaiting surgery, she first writes "Nice hat!!!" A few seconds later we see the pad again, and the exclamation marks have disappeared. Shortly after, they are back.
H. Con-172 - S3-E11
Audio problem: Toby enters the Oval Office at the end of a meeting the President is holding with about a half-dozen people. The meeting breaks up and Toby follows Bartlet toward the desk as the others meander toward the door. A few seconds after the camera pans away from the others, we hear the door close and the room is now silent as Toby and Bartlet begin to converse. But the door closing happens way too soon for all those people to have gotten out of the room. Two men are especially just standing there, looking as if they aren't planning to leave at all. The other doors aren't used nor heard. (00:14:15)
Factual error: In this episode, it is Inauguration Day in January. In the previous episode, when CJ is visiting her father in Dayton, Ohio, it is February, according to CJ (when she complains that it will be too cold to go fishing with her father).
Other mistake: CJ is in Dayton, Ohio visiting her father. She is in the middle of her high school reunion speech when Toby calls from the West Wing. It is light in D.C. outside Toby's office window, but CJ is giving her speech at night when it's dark out.
Visible crew/equipment: As Bartlet enters the Oval Office, Babish stands waiting inside. The shadow of the panning camera darkens Babish's face considerably as it moves right to left. (00:39:20)
Answer: One of the kidnappers was having an argument with his girlfriend and dumped her. She called 911 about Zoe.
No, some woman had an argument with her boyfriend, and he kicked her out of the car in the rain. She tried to take shelter in an abandoned farmhouse and noticed the kidnappers holed up in there, and called 911.
