Visible crew/equipment: After Cora is rescued from the cactus patch, when Harry annoys her and tells her to keep a stiff upper lip while she's lying on the gurney, the reflections of crew members and two reflector screens are visible on Harry's red bike helmet.
Visible crew/equipment: When Johnny and Roy help Cora crawl along the ladder from the cactus patch located in a secluded area, just as Johnny tells her to take it nice and slow, the camera moves a bit too far to the left and then shifts back to the right, but not before we are able to see a crew member, equipment and a large patio-style umbrella.
Visible crew/equipment: When Roy treks across the ladder to get to the woman in the cactus patch, the outlines of the lav mic transmitter and wire are visible at the back, right side of Roy's shirt. Then, when Johnny's on the Biophone with Rampart, the outline of the mic transmitter is visible at the back, left side of Johnny's shirt.
Visible crew/equipment: When Brackett walks out of his office, Betty walks over to him and asks if it's okay to go to Dixie for help with the nurses' scheduling problem, and the bulging outline of the mic transmitter is visible on the back of her uniform, directly under its zipper.
Visible crew/equipment: When deciding how to rescue Cora from the middle of the cactus patch, Mike parks Engine 51 at the side of the road, beside the hill with the cactus. During the rescue there are closeups of Cora's husband standing beside Engine 51, and we see other things reflected on the engine instead of just the side of the hill. Additionally, his position in the closeups differs from where he stands in the wideshots.
Visible crew/equipment: While Roy is hanging off the side of the building with the second victim, Johnny's trying to tie off the swaying sign, then after he asks for some slack the second time, there's an overhead shot from the roof, and we can see the shadow of the camera and a bit of a crew member, at the bottom of the screen. Then a few shots later, from the same POV, we still see the camera's shadow, and we also see the leg of a crew member (white sneaker and dark pants) walk into the shot and back out, at the left of the screen.
Visible crew/equipment: At the scene of the swaying sign accident, when Roy and Johnny get the gear out of the squad the outlines of the mic transmitters are visible on the left side of Johnny's shirt and right side of Roy's. Once they're on the roof both of the mic transmitters' outlines are on the right sides of their shirts, and later when Roy and Gil are pulled up onto the roof, the bulging outline is visible again at Roy's right side.
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.
