a multi-stage launch process which begins with the use of numerous small jet-powered craft ("pushpots") to lift the station and begin its flight, JATOs aboard the pushpots to accelerate it to several thousand MPH, and finally solid fuel rockets which minimize weight by burning away their tubes as the propellant combusts. The descriptions of the Platform's heavy (steel) construction are unrealistic, given that weight is recognized as crucial. Suggesting that launchers will combust Beryllium in Fluorine to maximize energy per unit of fuel is not incorrect as far as energy release, but downplays spectacular corrosion and toxicity problem. Reception P. Schuyler Miller reported the novel was marked by "the fastest kind of action" and "the feeling of technical authenticity."
