Factual error: When Buck first sees the videotape left behind by Pastor Billings, Bruce Barnes tells him about a prophecy contained in "Daniel Nine, Chapter 27." As a pastor, Barnes should have known that the Bible is divided into chapters and verses. He should have said "Daniel 9:27," "Daniel Chapter 9, Verse 27," or "Daniel Nine, verse 27." The point is, "27" is the VERSE, not the CHAPTER. (01:15:05)
Factual error: Where Buck Williams goes outside to report on the attack he has an XL1 camera with him. We see that he grabs the microphone from the camera and uses it to make his report but in fact the XL1 camera microphone is not wireless or has a long enough cable for him to be able to pull the microphone off the camera and use it.

Factual error: The airline pilot wears a coat with captain's ranks on the sleeve but he's also wearing shoulder boards with a U.S. Navy Captain's insignia (you can tell by the star between the button and the stripes). Coats are worn either with the stripes on the sleeves or on the shoulder but never both. In another scene, you will see him having taken his coat off and still be wearing another set of shoulder boards, this time with airplane insignias. So he was wearing those shoulder boards underneath his coat with that other set of shoulder boards. Shirts have shoulder loops not boards.
