All of this very detailed information, upbeat as well as terrible, is conveyed by Bob Seamans in his fac- tual presentation of the sequence of major activities involved and is amplified by his personal and profes- sional anecdotes. This is truly a unique and important record of the Apollo program’s achievements and the United States’ demonstrated capability and technological preeminence. I hope this capability will be advanced broadly as we move forward with innovative and beneficial aeronautics, space exploration, space science, and applications activities. This book adds substantially to our knowledge base about the Apollo program’s conduct and accomplishments and provides a firm path for further.
