<human>: Can you recommend a good book on the history of space flight?
<bot>: I would recommend 'The History of Spaceflight: A Chronological Encyclopedia' by David Baker. It is an encyclopedia-style book that covers the entire history of spaceflight from ancient times to modern day. It includes detailed information about each major milestone in the history of spaceflight, as well as biographies and descriptions of many of the key players involved.
