This shows the entire Launch Complex 39A shortly before the launch of Apollo 11; however, the important part is the apparatus underneath Apollo 11. It is NASA’s Crawler Transporter (CT). This “Crawler” rocket transporter was made by Marion Power Shovel Co., Marion, OH. This was made in 1965 and used throughout the Apollo program. According to the website (http://www.heartlandscience.org/trans/landveh), “The Marion Power Shovel Company in Marion, Ohio, in 1965 built the world’s largest land vehicle, NASA’s Crawler Transporter (CT). It played a key role in the Apollo program, which landed Americans on the moon, and then tackled a new mission to help launch the space shuttle fleet. Bucyrus International acquired the Marion Power Shovel Company in 1997.”
