Did You Know?


At the shooting range no cases are ejected from the rifles as they fire, and there are no cases on the stations or in front of the soldiers. Even though a case is ejected slightly forward from a rifle, there would be at least some right next to the soldiers. We only see a case being ejected as the shooters unload their rifles by pulling back the breech after the order to clear the weapons have been given. This would not have happened with a live round, as the gases from the gunpowder would have ejected the case when and the chamber would've been empty. All this reveals that blanks are being used in this scene. See more »


G. Callen: Hetty, how did you know to pull back the police and firemen?
Hetty Lange: I trusted my gut.
Sam Hanna: You risked the team and millions of civilians on a gut instinct?
Hetty Lange: That and 2,000 years of military history. The technique of strategic envelopment was a favorite of Sun Tzu, Alexander the Great, Napoleon Bonaparte...
Sam Hanna: What has been is what will be.
Hetty Lange: There is nothing new under the sun.
