The Lighter-Than-Air Man - S5-E8
Visible crew/equipment: At the scene of the bride and groom's traffic accident, when Johnny asks Crockett if he ever thought about a career as a marriage counselor, the outline of the lav mic transmitter is visible on the front of Johnny's shirt.
Visible crew/equipment: When Gage and DeSoto are on their first run (the mother-in-law), they phone Rampart's base station. When Dixie opens the door to answer the call, her mark (strip of black tape) is visible on the floor just as she steps on it.
Visible crew/equipment: After Brackett tells Donny's mother that her son does not have meningitis, it cuts to an exterior shot of Roy and John driving in the squad, and the moving shadow of the filming vehicle is visible on the ground, in front of the squad.
Visible crew/equipment: After Chet falls through the roof at the structure fire, when Truck 3 raises their ladder, we can see the cameraman/camera's shadow just as the ladder reaches the roof.
Visible crew/equipment: When Dixie tells the attendants to wheel Ruthie, the woman who went berserk at the salon, into the treatment room where Dr. Early's waiting, there are two T-marks visible on the floor at Dixie's and Johnny's feet.
Visible crew/equipment: After Station 51 is dispatched to the fire at the marine salvage yard, when they arrive at the scene we can see a second cameraman on his knees beside the camera, as he is shooting footage of the ship from that specific angle, which we see during this scene.
Visible crew/equipment: After the guys rescue the woman who was trapped upside down in the wrecked car, when they load her into the ambulance, the location set lighting is reflected on the glass of the ambulance doors.
Visible crew/equipment: After the two guys fill the fish tank with water, when they walk out of Brackett's office Dixie walks in, and as she comments that the tank is classy, the actor's tape mark is visible at her feet, in front of Brackett's desk.
Visible crew/equipment: After Station 51 is dispatched to the landslide, when Mike pulls the engine over on the side of the street, as Captain Stanley and Chet walk past the front of the engine, the cameraman's and crew member's legs are reflected on the windshield.
Visible crew/equipment: When the man who was unconscious for five minutes is wheeled into the ER, Morton has him taken to treatment 2, and when Carol is taking his blood pressure, the actor's tape mark is visible at her feet, under the gurney.
Visible crew/equipment: After Roy climbs down the manhole, he leans to the right (the second time), and when he points the flashlight down the tunnel on the right, the moving shadow of camera equipment is visible on the wall. We know it's not Roy's shadow because when he leans back to the left, that shadow is still moving on the tunnel wall.
Visible crew/equipment: When Engine and Squad 51 are at the cliff with the young unconscious boy, Captain Stanley calls in to dispatch, with Stoker standing beside him. The reflection of the camera crane and location set lights are visible in the side door mirror.
Visible crew/equipment: When they wheel Dianne (the OD) into the ER it's one long continuous shot from receiving to treatment 1, shot from the POV of the patient lying on the stretcher. As she's wheeled into treatment 1, the camera faces Johnny so we can see up the hallway behind him, and the entire admitting desk and waiting area are all blacked out, and there are two men, one of which (possibly the director) is sitting on a chair facing up the hallway where Johnny is and the scene is taking place.
Visible crew/equipment: When Squad 51 is dispatched to the car on top of a roof, it cuts to John and Roy driving in the squad as John responds to dispatch, and the reflection of the filming vehicle is visible on the squad's surface.
Visible crew/equipment: When Roy and Johnny are dispatched to the plant with an 18 yr old whose arm is caught in a machine, the outlines of the mic transmitters are visible on the left side of Johnny's shirt, when he's on the Biophone, and on the left side of Roy's shirt, when he's putting the tourniquet on the 18 yr old.
Visible crew/equipment: After Dianne's OD, once she passes out and Johnny begins to work on her and inserts the esophageal airway, the bulging outlines of the mic transmitter and wire are visible on the back of Johnny's shirt.
Visible crew/equipment: When Roy and Johnny leave Rampart and are heading back in the squad, about 16:40 minutes in, as they are discussing whether Roy has told his wife about house hunting, you can see two signs on the ceiling of the squad's cab. The signs say 'Emergency Saturday 8PM Rehearsal Mark VI Prod'. Possibly they are magnetic signs for the squad doors so people don't mistake the squad for a real fire department vehicle? (00:16:20)
Visible crew/equipment: While Roy and Johnny are climbing up to rescue the boy on the bridge, there's a closeup of the boy as he breathes heavily. When this shot pans to the right we see Roy (his stunt double actually) place the rope behind his back, and a mysterious dark gloved hand quickly appears behind Roy (and it's not Johnny's hand).
Visible crew/equipment: When Gage and DeSoto are driving away from Rampart, discussing DeSoto's possible purchase of a new house, dispatch calls about a traffic accident. In this exterior closeup shot of Squad 51, the reflection of the camera's flatbed vehicle is visible on Squad 51's red surface.
Visible crew/equipment: After Roy and Johnny speak to Chet's friend the realtor, when Station 51 is being dispatched to the accident on Harbor Freeway, in the overhead shot of the apparatus bay, we can see the shadow/reflection of production equipment moving on the engine's windshield.
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.
