Could We Start Again, Please? - S11-E7
Visible crew/equipment: In the ER, when they move Hattie off Norris he grabs hold of her hand, and two shots later in the closeup as Norris lets go of Hattie's hand, the white T-mark is visible on the floor. (00:04:55)
Crazy Love - S11-E19
Visible crew/equipment: You can see the camera recording in the glass when panning over Arizona.
Other mistake: The exact same shot of Derek's radio tuner is used twice-once when he calls Amelia and again when he gets in the car after helping at the accident. Both times, the clock says 7:45PM, but Alana (the AP class taking, cello playing student) says that she's supposed to be at school, implying it's sometime between 8AM-ish and 3PM-ish. Also, the sun sets around 7:30PM in Seattle on March 26, but it is obviously day time for the duration of this scene so there's no way it could be 7:45PM in either of the shots in which the clock is shown. (00:03:30 - 00:18:40)
