Character mistake: When Rat is in the Cyber Cafe, just after he has pressed enter on his computer to send the file "unsung heroes.doc" over the Internet, the message "on it's way" appears on the computer screen, but the correct message would be "on its way."
Factual error: The view of the Earth at the end of the movie while the credits are rolling shows a sunrise line advancing in a direction that appears to be east south-east.
Character mistake: When Zimsky talks about using DESTINI again, he says something like "a shock can stop a heart, and it can also restart it." That is a fundamentally false assumption that TV and movies get wrong all the time. Once a heart has actually stopped you can never shock it back. You can only shock a heart that is out of normal rhythm.
Suggested correction: The premise is the core, like a heart, is still beating. A shock destabilizes the rhythm of the heart, and without further help, the heart will stop beating. Destini did this to the core by sending a shock and destabilizing the core and without help, the core would stop spinning. A shock to a destabilized heart can shock and restart the heart back to normal rhythm. That is the theory of Destini restarting the core. At no point has the core or the heart fully stopped or flatlined.
Factual error: The shuttle crashing into Los Angeles is shown flying toward the northeast, from over the ocean toward downtown. Coming down fast, it turns slightly and lands in the L.A. river. As it's coming down, it passes over Dodger Stadium, which is north of downtown, not between the ocean and the river, and faces away. For the shuttle to fly from the outfield toward home plate, it would have had to fly past the city and turned around, which according to the dialogue it didn't have the altitude to do.
Factual error: The Army officer is American, by the US pips on collar and American airborne on shoulders...yet he has Canadian Airborne Cherry Jumper jump wings on the right front breast. (00:05:57)
Factual error: At the end, the aircraft carrier is at flight quarters for SAR (Search And Rescue) operations. They would not let Rat, or anybody, walk around on the flight deck 1) without any protective equipment and 2) a civilian without some kind of escort.
