Visible crew/equipment: When Station 10 is dispatched to the factory fire, a few shots after the closeup of 105's door that reads "fire dept deluge", there's an overhead long shot of the men using the hoses against the fires in the doorways, and a cameraman wearing blue, holding a handheld camera, is visible sitting at the back of a squad.

Visible crew/equipment: As the camera pans to the left at the start of this episode, while everyone is asleep in the dorm upstairs, a crew member standing near the production's lighting equipment is visible between Squad 10 and the wall. Also note that the lighting equipment is gone when the guys are dispatched.

Other mistake: At the very start, when the camera moves through Station 10 while the guys are asleep upstairs, we see one of the engines has license plate E111196, but en route there's a closeup of Rescue 10 and its license plate is also E111196.

Visible crew/equipment: At the construction site, when Roy and Johnny walk across the tower crane's main jib, there's a shot of the entire top of the crane, and we can see the cameraman at the tower peak, who is shooting the footage of the stunt guys from the overhead angle. He wasn't in the previous long shot of the crane. This does not refer to the officer who is standing on the main jib.

Other mistake: When the electrocution victim is loaded onto the ambulance, we can see there's a large piece of rectangular material adhered to the ambulance back door, with the name Mayfair printed on it. Then when the ambulance arrives at Rampart, the word Mayfair is now huge on that back door and the "M" is even over the door lock.
Visible crew/equipment: At the scene of Paula's traffic accident, after the ambulance leaves with Johnny and Paula inside, Roy pushes the back of the driver's seat forward revealing Bonnie in the back seat. When it cuts to the next shot, the reflection of a crew member leaning forward is visible in the car's window, and the mic is also visible on the left. Additionally, Johnny is visible in the background, even though he just left in the ambulance with the victim, as the actor who portrays him, Randolph Mantooth, is casually leaning on a sign post waiting around during the location shoot.

Continuity mistake: When DeSoto and Gage arrive at Rampart their black helmets are not hanging in Squad 51, when they enter the hospital. A moment later, when they're dispatched, both helmets are hanging in their proper place behind the seat. The distance between the squad and ambulance has also increased.

Then, as soon as Brackett and Early enter their door, in the next shot as Dix speaks to the officer, it's treatment 5 beside the nurses' station.

Revealing mistake: After Squad 51 is dispatched to the 'electrocution in a house', while Johnny goes to the garage to turn off the power, Roy waits at the doorway to go inside to the victim. In this interior shot facing the doorway, we see what is supposed to be the brick chimney at the side of the house next door, and the top of that set is visible. Plus the fact that this chimney is not nearly as deep as the one they passed by in the exterior shot.

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.
