Visible crew/equipment: When Roy and John are in The Boat with the victim of the explosion, the ambulance arrives and just as it passes by we are able to see a nice reflection of crew members, location set's 9-bank array lighting, reflector screens, a ladder and other equipment.
Visible crew/equipment: After Roy and Johnny pick up supplies at the nurses' station, they walk down the hallway and stop midway to talk about Johnny's insomnia. After speaking a few moments, Johnny and Roy head for the exit, so the camera follows them without cutting away, and when a father and son enter the hospital the camera turns, without cutting away, and follows them up the hallway. Just before the father and son reach the nurses' station, the actors' two black tape mark are visible on the floor behind them, precisely where Roy and Johnny had been speaking.
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.
