Paper Work - S6-E11
Continuity mistake: When the car swerves to miss the dog and hits the fire hydrant, the area of ground around the front tire is bare, but in the closeup as the man and his son exit the car, that area is now covered in vegetation, enough to cover half the tire.
Paper Work - S6-E11
Continuity mistake: When the new supply nurse gives Roy the box of supplies, in his right hand Roy holds the receipt and supply box, and in his left hand is the handie-talkie, but in the closeup Roy holds the supply box with his left hand and a bag of saline in his right hand.
Captain Hook - S6-E8
Visible crew/equipment: When Marco is speaking with the deputy at the site of the wrecked chopper, the bulging outline of the mic transmitter is visible on the left side of his shirt, above the belt.
Continuity mistake: When Johnny and Roy are in the staff lounge waiting for Dr. Morton, Johnny's holding the newspaper's sports page, and in the page's close-up, there is a large picture of Brice centered between two columns of articles. However, when Johnny's talking to Roy and Dr. Morton, that page is entirely different even though he hasn't turned the page.
Loose Ends - S6-E12
Continuity mistake: When Roy and Johnny are driving to the hamburger stand and stop to have a look at the squad's fanbelt, in the interior shots Roy is wearing his watch while driving, but when he exits the squad the watch has vanished.
Captain Hook - S6-E8
Other mistake: As the fire apparatus are leaving the station for the helicopter rescue, the shot from the front shows doors at the back of the building but when they are leaving it shows a brick wall at the back of the building.
Suggested correction: When Station 54 are leaving for the "aircraft down" rescue, in the exterior long shot from across the street (of the real Station 127), we are not seeing the apparatus bay with a head-on frontal view. The camera is positioned so that viewers see the apparatus bay at an angle, and we are only able to see the very long interior left brick wall, with the doors to locker room/bathroom and the dorm. The back of the building with the rear roll-up door is simply not visible at this particular angle.
