Factual error: The commercial 747 landing in Washington from France is the president's plane Air Force One, not a regular passenger jet. It's actually reused footage from the film Air Force One.
Visible crew/equipment: When Gibbs and MaGee are reviewing Parsons' military record, the boom mic is reflected in the TV screen.
Factual error: In the scene on the plane when Tony is going to inject the Epi-Pen, it shows him placing it against her thigh and pushing the trigger. In actuality, an Epi-pen is automatic and he actually pushed the end that the needle comes out of.
Chosen answer: "Policing your brass", means to pick up your expended shell casings, after firing your rifle, or pistol.
