The Sum of All Fears

Deliberate mistake: When asked about the effects of a gas attack on a village in Russia, the president is told that the effects were similar to end stage cerebral palsy. One major problem - cerebral palsy is a chronic condition, not acute. The condition itself is not fatal.

Deliberate mistake: When Ryan is entering the Pentagon to use the hotline, he swipes Cabot's ID card multiple times until finally the gate opens. There are two problems with this. First, if the system beeps, as it did every time he swiped, that means the system saw the response from the card so he shouldn't have needed to keep swiping. Second, the entry to the Pentagon uses a two-factor system, meaning you need to swipe and then enter a corresponding PIN on the keypad that was quite visible in the scene. This is to prevent exactly what Ryan did, namely steal an ID card and use it to get into the Pentagon since the thief wouldn't know the PIN. Since the keypad was there, for the movie the director must have decided all the real steps were too hard to fit the kind of scene he wanted so left it out. (01:44:00)

Question: Now i don't know much about missiles and such, but in the scene where the Israeli fighter jet is carrying the nuclear warhead, and is then shot down, well wouldn't the bomb blast that destroyed the plane also detonate the nuke attached as well? correct if i am wrong.

Answer: Nope. A nuclear detonation requires a highly specific sequence of events to occur within the bomb - an explosion nearby wouldn't come close to producing those conditions. The construction of a nuclear bomb requires components to be placed in a highly specific configuration - damage to the bomb would disrupt that configuration and make it effectively impossible for the bomb to go off.
