Factual error: At some point Jack tries to get a message to CTU about the fact that he is being held hostage. The enemy sees Jack writing and tells Jack to shred the message. I work in government security. Believe me, no government agency would have a simple shredder that just cuts the paper into strips. Required is a cross cut shredder that breaks the paper into almost a pulverized state.Kathleen Albers
Audio problem: When we see the timer for the bomb on the plane, you hear the beep to indicate each second it clicks down. However, we see the timer say 24 seconds. We hear several beeps and 7 seconds later the timer says 20 seconds. The key point of the program being real time, so the timer should be on 17 at least. (00:37:30)Ssiscool
Visible crew/equipment: Jack Bauer and his boss are in a building at night with a shooter hidden somewhere. They open a door and look very carefully to the right and then to the left before going through the door. On the right side you can briefly see two crew members and as the camera pulls forward they back up some so they won't be seen. (00:23:50)
Continuity mistake: At about 2:15am, when Jack's talking to Nina about the passenger list on the plane, we see a shot of Jack in the top left, and Nina in the top right. Because it's real time they're both meant to match up - we're watching them both at the same time. In each shot we can see the back of the other's head, but while Jack is looking down and around in the left-hand shot, in the right-hand shot his head is staying perfectly still. (00:15:51)Jon Sandys
Continuity mistake: When Jack drives to 18166 San Fernando Road he stops the car, gets out and leaves his phone in the car - you can see the green light of the phone's screen - he didn't reach for it. However, when Teri calls him, he has the phone in his pocket.Bjoern_Buller
Continuity mistake: The show claims to be in real time, and although those viewers who aren't too eagle-eyed will argue that it is, there is undisputed evidence in this episode that it isn't accurate. After the final ad break, the clock reads 03:52. At least two minutes later, when we see Teri and "Alan York" turn a corner in their car, the clock is displayed at the bottom of the screen, and it is still 03:52. The same sort of thing happens earlier in the episode, when there is a good ten minutes or so between when the clock says 03:26 and when it says 03:30.
