Here's a list of awards and commendations received, along with the story about how the document got started, and how it became popular. The 2001 update has concentrated on use of the web as the primary medium for users to access the Basics of Space Flight. Users will benefit most from the web version with its extensive links and animations. Page breaks are not controlled in this process, so they may appear in strange places, such as immediately following a heading. However, the links for navigation within the document have been retained.
