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: Tru arrives "more than three hours late" for the MCAT and then begins the test. Firstly, it would be pointless for her to even bother going at that time, since she'd have already missed the entire Verbal Reasoning section and possibly the Physical Sciences as well (depending on how much more than three hours she was late). Secondly, that's really a moot point since late arrivals to MCAT testing centers are not permitted to take the test.
Epiphanies - S2-E13
Factual error: Early in the episode a damaged Viper makes its way back to Galactica with its port-side gun trailing smoke as if in an atmosphere. But in a vacuum, the smoke wouldn't trail. It would build upon itself much the way shaving foam does when slowly leaking from a damaged can, unless the ship changed course and/or speed and then the smoke would appear to do the opposite - ship turns right, smoke moves off to the left because it remains on its original course regardless of what the ship does. The gun is not propelling the smoke rearward. The ammo inside is simply burning. (00:05:15)
Factual error: When they first assault the city, the Greeks construct catapults. Only problem: catapults were invented at 400 - 300 BC, i.e. about 800 years later; and the first models looked similar to giant crossbows. The one-armed onager and similar types (as seen here) were a later Roman invention.
Chapter 12 - S2-E2
Factual error: After Oro Dassyne has boasted about his fortress' defenses and the droid standung by him announces that he has spotted two Jedi approaching, Dassyne snatches the binoculars from him to take a look himself. Curiously, he holds them at a very different angle, i.e. he is not looking into the same direction the droid was looking, and still he spots the Jedi immediately.
Wavelength - S3-E8
Factual error: When Cyborg learns the hard way that Bumblebee can fly, his inbuilt Sonic Cannon rips a hole into the wall which glows with heat. A sonic weapon does not work with heat; it would shatter the wall, not melt it.
The Invisible Hand of Fate - S3-E3
Factual error: When Billy is in his first Underground Quiz Match, the host says at the start of the match "Jeopardy Rules apply," then starts with the first answer. Billy buzzes in with the correct question and wins it, however, Jeopardy Rules state that contestants may not buzz in before the host finishes reading. If they do, they lose their chance to buzz in first. (00:07:20)
Factual error: The crash took place in 1987. When we hear about the American salvage company that was hired to find the wreckage, we see a scene of traffic in Washington, DC that has a model of Lincoln Town Car that was not produced until 1998.
