Continuity mistake: When the patients who were treated at 86's arrive at the ER, Dix has Morton take the asthmatic boy with bronchitis into treatment 1. Then, when Roy is with Early in treatment 4, Early tells Roy to go to treatment 1 to ask Morton if he needs help, and when Roy walks into treatment 1 we can see that it's not really treatment 1, it's actually treatment 4 just playing the part of treatment 1.
Other mistake: After Engine 51 and Squad 51 are dispatched to "man trapped," while en route to the incident Engine 86 becomes available, so when the dispatcher cancels Engine 51 we hear Captain Stanley respond, "Engine 51," but the subtitles read that Johnny is the one who responds "Engine 51," which is pretty silly since John and Roy are in Squad 51. Subtitles from Universal Studios 2010 DVD.
Visible crew/equipment: When the police officer who was struck by lightning is wheeled into the ER, just as Dixie, Brackett, and Early walk up the hallway, the two tape marks are visible on the floor right outside the doorway of treatment 2, where Dixie is about to stand. Additionally, we can see the outline of the transmitter wire on the back of Dixie's uniform.
Continuity mistake: While Roy and Johnny are at 86's treating everyone who is being brought in, when Johnny's on the Biophone with Brackett, in Brackett's closeups at the base station, we can see that the actor has a very swollen upper lip. When the officer who was hit by lightning is brought into the ER, Brackett's lip is much less swelled, and more the way it normally looks, but when Brackett is back at the base station, his upper lip is swelled up once again.
Visible crew/equipment: When the woman drives her car up to Station 86 with the two injured passengers, the outline of mic transmitter is visible on the back of her sweater, when she gets out of the car.
Visible crew/equipment: When the psychiatrist comes to help at Station 86, as she leans over to clean the man's head wound, the bulging outline of the lav mic transmitter is visible on the back of her blouse.
Visible crew/equipment: At Station 86, when the woman brings in her asthmatic son, and talks to Johnny outside, the bulging outline of the mic transmitter is visible on the back of her blouse. Then later, when Johnny walks over to the boy's bed because the patients are being moved to the chopper, the bulging transmitter outline is now at her side.
