Continuity mistake: When the firemen cover the tanker in foam, the paramedics and ambulance drivers extract the tanker driver and place the patient on the stretcher they all get covered in foam, including the stretcher. Next shot, the stretcher, the patient and the men are all clean.
Continuity mistake: When Frankie flies the Cessna, he places an oxygen mask on his father. The style of the mask changes from either a round, large type, to a smaller, square type.
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.
Continuity mistake: At the gas station, when Captain Stanley asks Marco to open the gas pump and close the shut-off valve, Marco is wearing two rings - one on each of his ring fingers, but when he is nearly electrocuted both rings have vanished.
Audio problem: At the site of the crashed plane, when the trapped pilot screams, "Help, I can't get out, the doors are jammed," his mouth movements do not sync with the words we hear. Then once he's out, it happens again when he says "I guess I'm a little shook."
Involvement - S5-E19
Revealing mistake: The former head nurse is supposed to be unconscious when she's picked up from the couch. Yet she puts her hand up on a shoulder when being carried out.
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)
Continuity mistake: Frequently during the first two seasons there will be long shots of Squad 51 running down the road but it has mysteriously become a mid-60's Dodge (easily visible because of the red painted grille) instead of the familiar 1972+ model Dodge with a chrome grille. It also has 51 on the door which makes for a significant paradox.
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.
Continuity mistake: When Dixie goes to the waiting room to get Pete Barlowe so she can bring him to see Brackett, we see Carol, the nurse with black hair, working behind the admitting desk, but in the next shot Carol is in the treatment room with Brackett and Pete's wife.
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.
Visible crew/equipment: When Squad 51 is dispatched to the car on top of a roof, it cuts to John and Roy driving in the squad as John responds to dispatch, and the reflection of the filming vehicle is visible on the squad's surface.
Revealing mistake: When Station 51 is dispatched to the bomb threat, just as they roll up on scene, in this specific POV the corner edges of the screen are blacked out due to the lens that was used, but when it cuts to other angles it's gone, then it reappears with that POV. We see it three times.
Continuity mistake: Just before Engine 51 and Squad 51 arrive at the scene of the hang gliding incident, there's a long shot of the victims lying injured on the side of the cliff, and when the camera zooms out we see Johnny and Roy with the informant of the accident standing at the top of the cliff, even though Squad 51 hasn't actually arrived at the scene yet. That same shot is shown a minute later after they all arrive, when Roy says that he'll get some equipment.
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.
Bottom Line - S6-E17
Visible crew/equipment: When the guy walks into the ER with the white phosphorous burn, the outline of the lavalier mic transmitter is visible on the back of Dixie's uniform.
Audio problem: After the rescue at the refinery fire, while they load the ambulance, when Roy and John are being thanked the man's mouth movements are not in sync with what we hear.
Continuity mistake: When they bring the Hermit into the ER, Brackett tells them to take him to treatment 4 and he's wheeled there, but in the shot from inside the treatment room we see that he's actually inside treatment 1.
Visible crew/equipment: When Station 51 is dispatched to a man over the cliff, while en route there's a shot from the top of Engine 51, with the dome light in front of the camera, and the reflection of the covered camera, which is mounted on the engine's roof, is visible in the dome light's chrome surface.
Family Ties - S6-E16
Continuity mistake: When Station 51 is dispatched to the 'traffic accident with people trapped', time out is 10:23, but when Roy takes the man's blood pressure his watch reads 9:00, and when Johnny's on the Biophone with Rampart his watch reads 11:25. Then when John gives Rampart the second set of vitals, his watch reads 2:20.
Answer: I believe you are speaking of the old man, Mr. Wilson. He's played by J. Pat O'Malley.
Bishop73
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.
