Audio problem: When Squad 51 is being dispatched to 'man unconscious possible heart attack', this particular view we have of the apparatus bay shows the brick wall where the bay's door track is located on the right of the screen, and we can see that the bay door is up, but when Roy turns on the squad's ignition, we hear audio of the bay door opening even though it's not actually closed.
Audio problem: When the guys reach the top of the tower ride at Oceanland Park, we hear Captain Stanley say, "Kelly, you go up on top and throw the tag line over the side, we'll take the stokes up that way," but Cap's mouth is saying something entirely different.
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.
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.
