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.
How Green Was My Thumb? - S3-E17
Other mistake: Eric Shea appears in "The Hard Hours" as Clyde, the boy who built a full size rocket, but he's mistakenly listed in the credits at the end of this episode.
How Green Was My Thumb? - S3-E17
Other mistake: During the refinery fire, while Roy is with Fernando the first victim, we hear Roy say, "It's OK, you're gonna be all right," but the subtitles read that Johnny says that. Subtitles from Universal Studios 2010 DVD.
How Green Was My Thumb? - S3-E17
Other mistake: When Station 51 is dispatched to the fire at the winery, just as Squad 51 rolls up, in this semi-closeup we can see that it's Roy driving and exiting the squad, and also that it's actually Randolph Mantooth's double exiting the squad and getting the drug box from the side compartment. Also fun to note the difficulty the double had just opening the squad's door.
Other mistake: After Dr. Early fixes the squad's engine problem, while Roy and Johnny are driving away, Roy's watch reads 10:30, but when the dispatcher sends them to the leg injury he says that the time out is 11:52. Then at the scene of the football player's leg injury, Roy's watch reads 8:15 and Johnny's watch reads 9:30.
Other mistake: After getting the hermit out of the cave, Roy asks Marco to take the EKG leads "over there", but then hands them to Chet (played by Tim Donnelly) saying "here Tim", and the subtitles read that Roy says "Chet."
Other mistake: During the fire at Hammond Chemical, when Engine 7 rolls up and lays duals, we can see the vinyl material adhered to the top of the cab covering the engine company's real number.
Propinquity - S3-E20
Other mistake: When Station 51 is dispatched to the traffic accident, while en route first we see Engine 51 with nobody on the back, but then we see two firemen standing at the back, and they are Johnny and Roy. This footage is from the episode "The Old Engine" in season 3, when Station 51 got the new Ward La France engine, and since the previous shift was still out with the squad, Cap told Roy and Johnny to jump on the back and join them on their first run with the new engine.
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.
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.
Other mistake: Just as Squad 51 reaches the Tank Motorway, in the shot of the squad as it drives towards the camera before it zooms out, look at the squad's license plate before it stops. Even through the haze, we can see that the plate number is not Squad 51's normal E999007.
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: 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.
Inventions - S3-E22
Other mistake: When Station 51 responds to the incident of the man who fell through the ceiling at his mother's house, the footage of the squad and engine pulling up to the curb of the house is from episode 3x15, "Messin Around", when they rescue Old Bill after he's collapsed in his house.
Inventions - S3-E22
Other mistake: After Johnny and Roy are seen carrying the semi-conscious worker during the chemical leak, Captain Stanley tells Mike to get the life gun, and tells Chet to secure a lifeline, then before he mentions getting the guys from the catwalk via the lifeline, we hear Captain Stanley tell the Battalion Chief (into his handie-talkie), "Battalion 14, Engine 41," even though he's Engine 51, not 41. Additionally, when Cap tells Chet about the lifeline, two firemen behind Chet are wearing helmets with no company numbers on them.
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.
