Johnny: Uh, hey, Roy...listen, I know this may sound silly, but you suppose you can call me Cap?

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.
