Continuity mistake: When the guy (Michael Conrad) with the gunshot wound is being wheeled out of the treatment room there is nothing on his face, but in the shot from the hallway as they exit the room suddenly he has a tube inserted into his nostril with tape holding it in place.
Other mistake: At the fire, while they're searching for the missing boy, Marco feels the partition for heat and shouts to Captain Stanley, "Hey, Cap! Cap!" but the subtitles read, "Hey, Chet! Chet!" Then after the boy's rescue, we hear the Battalion Chief say, "LA, this fire's contained. All copy. Out 1 hour," but subtitles read "Talk 1 hour." Subtitles from Universal Studios 2010 DVD.
Other mistake: At the start of this episode Squad 51 heads out to the construction site with the screaming woman, and Roy and John are in their full turnout gear, which means they've just spent the night at the station and it's early morning at the end of their 24-hr shift, yet back at the station Roy and John are getting into their uniform at the start of their shift, which is 8:00AM. Joanne Worley's screaming segment was filmed for an earlier episode, but was inserted into this episode.
Other mistake: When Roy and Johnny are at base camp during the fire, they're dispatched to the incident at Jawbone Canyon. While en route, Battalion 5 orders Engine 51 to approach from the north, and we hear Captain Stanley respond, "Engine 51, 10-4," but it's odd that the subtitles read that Johnny is the one who responds. Later, after Tanker 44 tanks 51, Chet says, "Cap, we've got a charged line," but the weird subtitles read, "Captain's going to throw us a line." Subtitles from Universal Studios 2010 DVD.
Continuity mistake: After the cropduster crashes, when Roy and Johnny pull the pilot out of the overturned aircraft and begin working on him, Johnny's medical holster with penlight, forceps and scissor is clipped at his right hip and the other holster's at his left hip, but when Johnny shouts to Chet about giving the victim oxygen, Johnny's holsters have switched sides.
Visible crew/equipment: When Engine 51 rolls up on scene at the paint factory structure fire, Captain Stanley heads towards the street corner, and we can see the actor's white T-mark on the ground before he gets on the HT.
Heavyweight - S3-E5
Visible crew/equipment: When the guy is stuck in the tree after his hang gliding accident, John ties the rope around the branch and begins to saw the branch while Roy uses that rope to slowly lower the branch. The problem is that just as the branch nears the ground, we can see the production crew's thin double lines securing the branch at the top right of the screen, and then those lines vanish when Roy joins John.
Other mistake: When Squad 51 and the engine company arrive at the rock quarry, in the shot after John tells Jason to get the HT, just as Roy, Captain Stanley and Mike walk towards the right side of the screen, something drops down from the top of the screen, enough to cover the top left corner of the screen area, then gets pulled back up.
Continuity mistake: When Station 51 is dispatched to an 'unknown type rescue', the woman who opens the door tells them she didn't call, and when Roy asks her if he and Johnny can check on her sick husband, Roy's second shirt button is open and his undershirt is visible, but in the next shot it's buttoned up again.
Other mistake: At the start, when Roy is reviewing the list making sure he got everything, there are two containers of milk on the counter which have their brand names covered. As an aside, watch Chet as he empties the grocery bag and puts the aluminum can in the freezer.
How Green Was My Thumb? - S3-E17
Other mistake: When Johnny and Roy take the elevator with the nurse, they take the elevator near the nurses' station, at the south end of the ER wing, and Johnny follows the nurse onto the 4th floor to try and get her name. This is completely impossible considering the actual floor plan of the hospital, since in all of the exterior shots of the ER it's only 2 storeys.
Continuity mistake: When Dr. Early and Marcia's father stand outside her semi-private room, number 104, we see treatment 4 is right beside it. There are two problems with this bizarre situation. First, when Dixie gave Early the lab results about Marcia's possible pregnancy earlier, treatment 2 is right beside treatment 4, not the semi-private room 104. Second problem is that when Early and the parents walk into Marcia's room, in the interior shots we can see that there's a perpendicular wall right beside the doorway to its left, where the hallway ends. (00:19:20 - 00:31:30)
The Promise - S3-E11
Other mistake: Richard is in room 603 and jumps out of the 6th floor hallway window. In the long shot of the exterior of the building, we see that he's lying on the ledge of the row of windows that are second from the top. The elevator shows 8 floors, which means that he's actually lying on the 7th floor's window ledge.
Continuity mistake: At the start, there's a long shot of the Land Rover driving down a long stretch of road towards the camera and then passing it. That road, landscape, and mountains are very distinctive. As Roy, John, and Chet continue talking and driving, when they reach the scene of a traffic accident, Chet sets up a flare behind the Land Rover and another flare behind the pickup truck, then Chet sees a car coming from the direction which the Land Rover was headed. The problem is that the road/landscape/mountains shown earlier in the long shot of the Land Rover, which had been driving from the opposite direction, is the same that's shown here, as Chet tries to stop the car. Then to top it off, when Chet first notices the second car in the distance, it's coming from the opposite direction of the first car, but once again the view is exactly the same.
Visible crew/equipment: At the start of the episode, in the closeup shot of Roy, Chet, and Johnny as they're talking about not catching any fish on their trip, there is a chrome spotlight on the roof of the Land Rover, and we can see the reflection of the camera mounted on the vehicle's hood.
Visible crew/equipment: When the woman staggers into the ER a nurse rushes over, and the actor's T-mark is visible on the floor in front of the admitting desk, where the nurse was just standing.
Visible crew/equipment: After Station 51 is dispatched to the fire at the refinery, when they reach the refinery and make a right turn the view is from atop Squad 51's roof, and the reflection of the covered camera and part of the cameraman's head are visible in the squad's lightbar.
Visible crew/equipment: After Squad 51 is dispatched to the 'heart attack' at Compu-Data, when Johnny and Roy walk in and then approach the victim in the office, the reflection of the moving camera dolly is visible on the office's large panes of glass. The camera equipment also casts a shadow on the three men as they walk toward the office, then on the glass as it moves back and forth.
Visible crew/equipment: When Johnny and Roy are leaning on the old fire engine talking about how it's not just some old car, and then when Johnny bends over and lays the mechanic's creeper on the ground, the outlines of the mic transmitter and wire are visible on the back of Johnny's shirt.
Other mistake: When the dispatcher sends Squad 51 on the probable overdose run, the address given is 2267 West Hill, apt 6, but when Roy and Johnny are at the door, both entering and exiting, the house number above the stairs is 11044.
Answer: On IMDB, actress Anne Schedeen is listed as playing Nurse Carol on six episodes from 1974-76.
