Other mistake: Before their next shift starts, when Johnny walks into the locker room whistling he turns the corner and walks through the doorway between the dorm and locker room, but what's odd is that right behind him there's a brick wall instead of the dorm.
Other mistake: At the start of shift, after Roy digs into Johnny for calling Joanne, Station 51 is dispatched to the children lost in the flooding storm drain and time out is 08:32. Then at the scene, the officer says that they got a report about two missing boys two hours earlier, and that a witness saw teenagers pull up the manhole cover just before noon, and another witnessed the two boys playing around the open manhole. So what time is it supposed to be - early in the morning or some time in the afternoon? The times just don't sync.
Other mistake: While 51's guys are at the accident scene by the freeway on-ramp, when Roy's standing on the ladder and says the car door's jammed, Captain Stanley tells Chet and Marco to get the Porta Power, but subtitles read "Jack, Marco, we need the Porta Power," even though there's no character named Jack.

Other mistake: Jamie Farr appears in 2x19 "Boot" as Alan Austen, the guy who claims that he can't move his arm because of a curse, but he's mistakenly listed in the credits at the end of this episode.
Other mistake: After Roy tells Captain Stanley, over the HT, that he and Johnny may have found something in the flooding storm drain, Captain Stanley uses his HT to contact Marco and Chet (who are driving Squad 51 while John and Roy are down below), and says "Squad 51, Engine 51..," but the subtitles read, "Car 51, Engine 51..."

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.
