Just finishing up adding all 39 episodes of this series to my collection. It aired in 1954-1955. I bearly remember this because I was 3 years old when it aired origionally. In these older sci-fi movies they had ray guns! It constanly blows me away that many of the things we saw in older sci-fi movies are now things we take for granted. The Rocky Jones Series was the first to use doors that would open automatically as I understand it.
