Corrected entry: When Mandy is talking to Tony in the apartment she says that two years ago he risked Michelle's life (in season 3). Three years seperated seasons 2 & 3 making this five years since season 2. However when Aaron is talking to the president in the next episode he mentions the attack on his life took place four years ago.
Corrected entry: Airforce One was chased and shot down by an F-117A stealth bomber by a disgruntled marine aiding the terrorists. The F-117 is not a stealth fighter. It carries Air-ground missiles and air-ground bombs but it cannot be modified to carry air-air missiles due to its down looking radar (which is probably why no missile type was named specifically).
Corrected entry: The last thing we saw at the end of the previous episode was Jack knocking out the terrorist suspect, who was tied up in the van outside CTU, before the clock ticked to 1am. At the beginning of this episode, which supposedly picks up the instant the previous one ends, the terrorist is in CTU medical receiving treatment. and he's fully conscious.
Corrected entry: Marwan's hi-tech gadget which he uses to track the path of his missile (the 'interface' of which CTU later reads to locate said rocket) is quite obviously a Nokia 7710. I don't remember seeing 'Nuclear Warhead Locator' listed in the special features of this model.Chimera
Corrected entry: Throughout this show, it is apparently possible to drive between any two locations in the Los Angeles area within half an hour. It takes Jack approximately half an hour to drive from the downtown train station where he sees Khalil lead Andrew away to isolated areas that seem to be at the edge of the city (we hear it is Ventura County). Even if the streets were empty, the Los Angeles area is large enough that this would not be possible in real life.
Corrected entry: It is not clear what time during the year this particular day takes places. It is a weekday, which we know the office in which Jack secures the override device from Habib is filled with workers. However, neither Behrooz nor Debbie go to school. It cannot be summertime because the sun sets before 7PM which is not realistic. At the same time, there is a school bus in the scene where Jack is following the terrorist Khalil toward the location where Heller and Audrey are being held hostage. If its during spring or winter break the bus would not be there.
