Trivia: A little aside - when the terrorists first strike, in amongst the confusion you can hear someone shout "get the football!" The "football" is the name used for the case which contains the nuclear launch codes, but this is never explained. It's not a major thing, but interesting to note that they included it as a little detail. Good to know a childhood spent reading Tom Clancy books wasn't wasted...
Trivia: In the scene where Harrison Ford is under the plane having the fight with the terrorist, if you listen really carefully to the music track, at one point when Harrison starts doing some damage you can hear the 7 notes from the Raider's of the Lost Ark movie. It's the "hero" or theme music used when Indie was kicking some butt.
