Visible crew/equipment: When Honora brings Pauline a tray of breakfast into her room, Honora gives her the tray then talks to her for a while. You can clearly see the face of a crewmember reflected in a window, and then after, you see the reflection of two hands holding the long pole of the boom mic! (00:37:40)
Visible crew/equipment: In art class, Miss Collins says "..and decide who wants to model and who want to draw." After saying this it cuts to a wide shot of the class, and in the windows (right side of the room) you can clearly see, reflected in the window, the whole long pole of the boom mic being slowly lowered.
