Once a Hero - S4-E8
Other mistake: When Abby is talking to the microscope guy during the line "you understand without having to go find a dictionary" there is a half second flash of another shot with DiNozzo walking off camera in a street setting. Maybe just a encoding error on Netflix but it persisted after reloading. (00:23:45)
Visible crew/equipment: When Gibbs is on the phone with Sharif, Gibbs asks him, "Who were they? Wife? Family?" and just as he says the word "wife" we can see an actor's red tape mark on the floor at the corner of DiNozzo's desk, which wasn't there a minute earlier when McGee walked over to DiNozzo. (00:31:30 - 00:32:45)
Visible crew/equipment: When Gibbs is discussing Lt. Seabrook with Dr. Pike, just as Gibbs says, "Gonna need your security tapes and access logs that you keep, Doctor," the cameraman's reflection can be seen moving on the glass surface. (00:10:25)
Continuity mistake: When the mannequin is hit it's on the double yellow lines with another mannequin stood on the lines behind the first one. When the 4x4 drives off, the second mannequin has moved on its own from the double yellow line to the side with the other 2 upright male mannequins. (00:00:45)
Continuity mistake: At the start, Otto hits the mannequin straight forward. Camera changes and now the mannequin is to the side of the 4x4. After the mannequin is hit, the woman looks out of her side window to look at it. However when we see the 4x4 drive off the mannequin is now on the opposite side. (00:00:50)

Audio problem: When the director is working out the letters on The Wall in the video feed her mouth doesn't move for the last L but her voice is heard. (00:38:20)

Continuity mistake: When DiNozzo is resting at his desk, he has he feet crossed with his left foot on top of his right foot. When the shot changes his right foot is now on top. His hands have also gone from clenched to unclenched in the same shots. (00:20:25)

Revealing mistake: When we see Ziva having a close up look at the dead girl, the dead girl's eyes twitch and move slightly. (00:09:20)
Once a Hero - S4-E8
Continuity mistake: The way Gibbs holds his ID out to the maintenance man changes between shots. In the first shot he has 2 fingers inside the ID in the second shot just his thumb is inside the ID. (00:07:40)
Once a Hero - S4-E8
Other mistake: Ducky states that the Bronze Star was for Valor. However, the bronze V that signifies the star was for Valor is not present. There is no way Ducky could know it was for Valor. (00:05:20)
Chosen answer: It is never stated, however she must have been there several years if she is on presidential detail.
