Other mistake: When dispatch drops tones for the fire at Graymar Plaza, we see Engine 8 rolling out of the apparatus bay and heading down the street, but the problem here is that this footage of Engine 8 is from season 5, episode "Equipment", when Johnny was at Station 8 doing overtime, and we can actually see Johnny sitting there on Engine 8 as it rolls by.
The Girl on the Balance Beam - S5-E18
Other mistake: The dispatcher gives the address of "woman trapped on a wire" as "Commercial Studios,1122 Dellini Plaza", and as Engine 51 drives past the front gates, the large sign reads "World Pictures Corp." Additionally, the address of World Pictures Corp is 1731 Carlson, when we see the same footage of Engine 51 driving past the sign in episode "The Exam" in season 6.
Captain Hook - S6-E8
Other mistake: When Roy and Johnny rescue the deputy from the wrecked chopper that sank in the water, they emerge from the water soaked from head to toe, but when they are pulled to the top of the cliff, Johnny and Roy are both completely dry except for a few small wet patches on their shirts.
The Wedsworth-Townsend Act - S1-E1
Other mistake: Before the car goes over the cliff, Dixie says that the woman has a fractured radius and ulna (forearm), and then at the hospital when Dr. Brackett talks to Dixie he says the same thing, but when Dr. Early walks into Brackett's office, he says "The woman with the busted fibula (lower leg), she's coming out of shock now."
Other mistake: When Pete shows Laurie the newspaper, in the closeup of the article about Gail and Laurie entitled "women paramedics save shooting victims", the paragraphs under and around the title are repeated, and have nothing to do with the title.
The Girl on the Balance Beam - S5-E18
Other mistake: Twice during this episode, when they're dispatched to a "woman trapped on a wire" and also to the "train fire", we see Engine 51 heading out with two firemen standing at the back of the engine, and they are Johnny and Roy. This footage is actually from the episode "The Old Engine" in season 3, when they got the new Ward La France engine for Station 51, and since Roy and Johnny were waiting for the previous shift to return with the squad, Captain Stanley told them to jump on the back and go with them on their first run with the new engine.
Other mistake: When Johnny, Roy, and the cardiac patient are stuck in the stalled elevator with smoke in the shaft, Captain Stanley notifies dispatch that he wants a full first-alarm assignment, and we then see Engine 8 pulling out of their bay and heading to their run. The problem here is that this shot of Engine 8 is from the episode "Equipment" in season 5, when Johnny was doing overtime with Station 8, and we can actually see Johnny sitting on Engine 8 as it drives by.
Loose Ends - S6-E12
Other mistake: At the fire in the freight yard, Captain Stanley asks the dispatcher to respond a second-alarm assignment, and then we see Engine 8 pulling out of their apparatus bay and driving down the street. The problem is that this particular shot of Engine 8 is from season 5, episode "Equipment", when Johnny was doing some overtime at Station 8, and we can actually see Johnny sitting on Engine 8.
Other mistake: When Roy and Johnny are waiting in the staff lounge for Dr. Morton, Johnny opens the newspaper's sport's section and sees Brice's picture. In the page's close-up, two paragraphs in two unrelated articles are the same, and they also have nothing to do with the title of the articles. The first paragraph begins, "Thus at this conference all our governments..." and the second begins, "Of no less importance was the common recognition..."
Other mistake: When Battalion 5 orders Copter 10 and Copter 14 to make an air drop on Jawbone Canyon, it cuts to a shot of Copter 14 taking off. This is the same shot used in S3, E6, "Snakebite", when 85's guys tank Copter 14 in order to make a water drop where the teenagers' car is on fire down below.
Other mistake: At the scene of the vehicle accident, with a raging fire going on, the Chief communicates over the HT with Copter 10, and when Copter 10 arrives and makes the water drop, it is actually Copter 14 we see in all the shots.
Other mistake: When Chet Kelly breaks his glass that he was drying in the first shot after showing Station 51, Captain Hammer is on the phone and begins walking to Chet when he groans after breaking the glass. Then it switches to another shot where Marco Lopez yells "Medic!", and Captain Hammer reaches Chet. After that it switches to a shot where John Gage and Roy DeSoto walk over to Chet and the angle goes wide. At this point Captain Hammer hangs up the phone again and begins to walk over to Chet again. When it switches to the shot where Johnny and Roy reach Chet, Hammer is already there like he was when Marco yells for Johnny and Roy. No one else, like Mike Stoker, does this. (00:00:05)
Other mistake: When Early and Morton are examining Johnny, Early tells the nurse, "Type and cross" (the blood vials she's holding), but the weird subtitles read, "Cut and cross." Subtitles from Universal Studios 2010 DVD.
Fair Fight - S6-E5
Other mistake: Squad 51 is dispatched to the fighting couple three different times, and we hear the dispatcher give the address cross street as "Valleyheart," but all three times the subtitles read, "Valley Park." Subtitles from Universal Studios 2010 DVD.
Other mistake: When John, Roy, and Vince grab the officer who was shot by the sniper and make a run for it, as they duck behind the car, right behind them we can see a city bus just driving on by the lot, directly in the sniper's line of fire, even though that area's supposedly closed off with heavy police presence.
Other mistake: When Johnny and Roy leave for the parade, they turn to their left when leaving the fire station. When Station 51 is toned out to the structure fire, where John and Roy are, they turn to their right when leaving the station.
Other mistake: The Battalion chief assigns tanker 76 to assist engines 51 and 60 with the rescue at the canyon. However, it is tanker 44 that arrives.
Other mistake: When the plane crashes into the neighborhood and traps Gage and DeSoto in the house, you see outside shots of the squad when the other two paramedics arrive. You can see a large piece of smoking engine/plane laying on the back end of the squad, right over the spare air tanks. They would have exploded when something that heavy and hot landed on them, since they are filled with oxygen. The tanks would be full or they would not be on the back of the squad.
Suggested correction: Probably air tanks, because oxygen tanks are always painted green. Both kinds of tank are very tough. Hard to tell with how much force the plane debris might have landed except that the truck still looks pretty much intact. However, if the plot required it, I would find it completely believable that the crash could have exploded the tanks, but also don't find it strange that they didn't explode.
