At the Edge of Space: The X-15 Flight Program by Milton O. Thompson. paperback edition. ISBN: 9781588340788.

In At the Edge of Space, Milton O. Thompson tells the dramatic story of one of the most successful research aircraft ever flown. The first full-length account of the X-15 program, the book profiles the twelve test pilots (Neil Armstrong, Joe Engle, Scott Crossfield, and the author among them) chosen for the program. Thompson has translated a highly technical subject into readable accounts of each pilots participation, including many heroic and humorous anecdotes and highlighting the pilots careers after the program ended in 1968.
