From the back cover:
Spaceflight historian Jack Hagerty chronicles the evolution of the spaceship during the century by examining 75 of them... Jack delves into the background of each design, examining the motivations of and influences on the designers. Each ship is described and analyzed in detail. Each entry includes a data drawing by Jon Rogers sufficient for hobbyists and/or craftsmen to build a version of their own.
Nearly 100 pages are devoted to Werner von Braun's spaceships popularized by Chesley Bonestell. 160 pages are given over to the spaceships of comic strips, juvenile science fiction, film and television, such as Buck Rogers, Gerry Anderson's Thunderbirds, George Pal films, and 2001. And the final 60 pages feature unusual real spaceship designs that never went beyond the planning stages.
