Continuity mistake: When Morton and Early are examining the guy with stomach pain and cramps, Morton's stethoscope is around his neck with the earpiece at his left and the chestpiece to his right, but in the closeup it's the opposite way around, then it's back to the original way.
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.
Continuity mistake: When Johnny and Roy rappel down the cliff with the downed hang gliders, both of their lifebelts are buckled going from their left to right sides, but in Johnny's first closeups when he's with the second victim, Johnny's lifebelt is on the opposite way, note that it's buckled going from his right to left. Then once the glider falls Johnny's belt is on the original way.
Continuity mistake: When Roy and Johnny begin rappelling down the cliff to the injured hang gliders, Roy's not wearing the safety pack in the closeup, but as they're rappelling in the wide shot the large safety pack is suddenly on Roy's back.
Continuity mistake: When dispatched to singles club fire, Engine 51 pulls into the parking lot, and there's a shot of Mike hooking up the supply line to the hydrant, with Marco at the side of the engine, but it cuts back to Engine 51 in the lot again, with Mike behind the wheel and Marco sitting in the jump seat, and there is no supply line hooked up, then the engine drives further into the lot.
Continuity mistake: At the singles club fire, after Roy and Johnny go in to look for the missing man, we see Mike charging the lines, then there's a shot of two of 16's guys walking past the stairway with a hose, and notice that on the stairway we can see Johnny's and Roy's legs heading down the stairs. This same shot is shown again after Roy and Johnny check the men's room upstairs, and once again we see Roy and John coming down the stairs when 16's guys walk past 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.
