The 31 manned space flights in the National Aeronautics and Space Administration's projects Mercury, Gemini, Apollo, Skylab, and Apollo–Soyuz required 71 crew assignments, which were filled by 43 astronauts. This Demonstration presents dynamically controlled views of the many social networks that characterize those flights and astronauts. Aside from a study of personnel assignments in early space flights, this Demonstration illustrates a practical application for dynamic control of GraphPlot output. The flight designators have the following prefixes: Project Mercury, M; Project Gemini, G; Project Apollo, A; Skylab, SL; and Apollo–Soyuz, AS.
