Audio problem: When auditing the recording of one of the first hijacks, the FAA reviewer rotates the tape reels back and forth in order to find just the exact words from the hijacker. As the sounds play, the reel moves barely half a turn, but the reviewer rewinds it more than one revolution, not nearly returning to where that sound would be.
United 93 (2006)
1 audio problem - chronological order
Directed by: Paul Greengrass
Starring: Olivia Thirlby, David Alan Basche, Gary Commock, J.J. Johnson, Liza Colon-Zayas, Opal Alladin, Polly Adams
Continuity mistake: After the hijackers have taken over the plane, the blond flight attendant's hair, styled in a French Twist, keeps changing from messy (presumably from the chaos) to as smooth and neat as when she boarded the plane. She's never offscreen long enough to have simply fixed it. Not until the passengers revolt does it remain disheveled.
Mohammed Atta: We have some planes.
Trivia: Families of the 40 passengers and crew members killed on United Flight 93 cooperated in the production, offering Greengrass detailed background about their loved ones, down to the clothes they wore, what reading materials or music they had with them and what sort of candy they might have snacked on aboard the plane.
Question: How come the terrorists' knives were not noticed? Airports have metal detectors designed to detect knives.
Answer: At the time of the 9/11 incident, certain type utility or pocket knives like the ones the terrorists brought on board were not illegal. Airport screeners had more leeway then about what type of knives, tools, or other gadgets they allowed passengers to carry on board. Since then, the restrictions are far more stringent.

I can attest to this as my father traveled on aircraft with his pocket knife multiple times before 9/11. As long as it was under a few inches; it was more viewed as a tool than a threat to the aircraft.
