Visible crew/equipment: When Roy and Johnny are treating the man under the tractor, and subsequently Dr. Knott, the outlines of the Lav mic transmitter and cable are visible on the back of Johnny's shirt.
Visible crew/equipment: At the nurses' station, Early asks Dixie about Carol, and when Dr. Knott pulls away in the wheelchair to go get Carol, the actor's tape mark on the floor is visible, precisely where Brackett had been standing moments ago.
Other mistake: During the rescue at the studio, when Roy tells Marco and Chet that they need to latch up the wagon before it pulls the stuntman over the falls, we hear the dispatcher say, "Copter 10, respond with Engine 69," but the subtitles read, "Trucker 10, respond..." There is no such thing as Trucker 10. Subtitles from Universal Studios 2010 DVD.
Other mistake: When Squad 51 is dispatched to the movie studio, while en route in the interior shot, in the rear-view mirror we see the reflection of the driver's helmet, and it has an 18 on it, instead of 51.
Continuity mistake: At the movie studio, during the rescue of the stunt guy whose leg is trapped in the wagon, while both Roy and Johnny are standing in the water, they're wearing water-type boots with whitish, flat rubber soles.
Continuity mistake: After Early tells Dixie about the patient with an unknown illness, in the shot from the hallway, we see Carol taking him into treatment 4, which has a windowless door, but when Morton is examining him in the shot from inside the room there's a window on the door (looks like treatment 6).
Continuity mistake: When the woman from the car accident is brought to the ER, she's put into treatment 4, as mentioned by Dixie and all three doctors, and it has a windowless door, but when Early and Morton are speaking to the patient about the car accident, they're all in a treatment room with a window on the door (looks like 6, the one opposite the nurses' station).
Visible crew/equipment: When Squad 51 is dispatched to a drowning, just as Chet tells Johnny, "Don't go getting yourself damaged," the set lighting is reflected in the squad's spotlights.
Continuity mistake: When Dr. Early is with the farmer with the unknown illness and talking to Dixie, there's a tall dark item sticking up on the left side of the farmer's buttoned shirt pocket, and then when Dr. Knott stops to ask him questions the item is sticking up on the right side of the buttoned pocket. It could not have simply shifted sides in the pocket, because the pocket flap is buttoned at the center.
Visible crew/equipment: When Johnny walks out of the ER, and finds out from Sally that Roy's been spreading advanced publicity about Johnny's 'modeling career', and then when Dr. Knott joins them, the outline of the mic transmitter is visible on the back of Roy's shirt.
Continuity mistake: During the rescue at the movie studio, when Roy and Johnny wrap the line around the stuntman's waist, Johnny's belt does not go through his pants' back center loop, but a moment later after the wagon falls, when they pull the stuntman up, Johnny's belt now goes through that back loop.
Visible crew/equipment: When Dr. Knott comes back to the ER to see the tractor driver before he's discharged, he walks down the hallway with the nurse, and when he stops near Brackett he looks down at the actor's tape mark on the floor, then steps up to his mark. Then after Dr. Knott experiences chest pains, the two actor's marks in the two spots where Brackett had been standing, are visible on the floor as they walk to the treatment room.
Continuity mistake: When Roy, Johnny, and Chet are cleaning the locker room/bathroom while talking about the models' upcoming visit, dispatch drops tones for 'man trapped in a ditch', and then we see Johnny and Roy coming from the kitchen which is on the opposite side of the firehouse.
Visible crew/equipment: When all the guys are on the roof trying to rescue the unconscious man on the scaffold, the outlines of the lav mic transmitters are visible on the backs of Johnny's and Captain Stanley's shirts, as well as the back of the other scaffold worker's shirt.
Visible crew/equipment: When Johnny and Roy are trying to get the boy with Meniere's Syndrome out of the treehouse, the bulging outlines of the mic transmitters are visible on the backs of Deputy Pauling's, Roy's, and Johnny's shirts.
Visible crew/equipment: When Morton is talking with the fireman's widow, DeSoto tells Morton that Early wants to see him, and when Morton walks through the door DeSoto's foot moves, and we see the actor's black tape mark on the floor by his foot.
Visible crew/equipment: After Brackett tells Jenny that they may have to put Koki down, Dixie walks into Jenny's isolation room, saying that they have the latest lab report, and the actor's tape mark is visible on the floor at Dixie's feet.

Continuity mistake: When Johnny calls in to Rampart, Brackett answers and presses the two buttons to record the conversation, then tells Johnny to standby leaving the two buttons depressed, while the drunk driver is brought in. In the next shot, a closeup of Johnny, Brackett tells 51 to go ahead, and in the following shots Brackett continues to listen to Johnny, but none of the buttons are depressed on the tape machine to record the conversation. Then when Brackett gets off the line, he actually presses the tape machine's off button, as if the buttons had been depressed and the conversation recorded.

Continuity mistake: When Kelly and Gage have at it about the portrayal of Native Americans in film, DeSoto quips, "What are you picking on me for?" as he faces Gage in front of him. Gage then walks to the other side of the table and after he says, "We call that white man royalty syndrome," he puts his arm around Kelly, standing beside him. We are then shown DeSoto's reaction shot, who still faces Gage in the same direction as his earlier quip, and we also see Kelly behind him, but no Gage.

Continuity mistake: Before being shot at, when Gage and DeSoto climb up to the scaffolding, Gage lifts the man's head to rest on the scaffolding and stays that way in each of the following close-ups, but in the following four wideshots his head still hangs over the side.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.

Correct, it was J. Pat O'Malley...he also played the grandfather with his grandson when their rocket exploded, and also played "Old Bill" in the episode with Ann Prentiss, where Gage saves the little girl from the burning tree house, and her mother falls in love with him.
