Other members of the editorial and business staffs, some of whom held several positions at various times during the years the magazine was published, were Assistant Editors Robert B.

Caporaso, and Thomas T. Milkie and members of their families. Its paid circulation reached 15,000 by 1970. The launch of Sputnik in 1957 and the space race to the moon made model rocketry a popular hobby. Model Rocketry magazine was started at the height of the Apollo program. Each issue had plans and instructions for constructing rockets typically powered by black powder rocket motors such as those made by Estes Industries. There were also technical articles on model rocket design that would include several pages of theory and equations. There was a series of articles starting in October 1969 on writing FORTRAN programs to calculate flight parameters. The magazine also covered model rocketry clubs' launch meets and contests. From August 1969 to February 1972 Model Rocketry incorporated The Model Rocketeer, the official journal of the National Association of Rocketry. The September 1969 issue of Model Rocketry shown at the right has a typical cover design and contents. The cover photo shows the launch of a model rocket approximately 2 feet (61 cm) tall with a small camera as the payload. The camera will take a photo after the rocket reaches its apogee and starts its descent with a parachute. This issue also has construction plans for an egg lofting
