I found this book to be absolutely fascinating, coming from a typical `how did actually they do that?' engineers point of view I was in complete awe of the vast scale of the NASA moon landing programme which this book faithfully chronicles, ( in large A3'ish format ).
While reading this book I would frequently find myself thinking aloud `but to do that you would need a massive wind tunnel / launch pad / test range' only to turn the page and be presented with a huge photo of said wind tunnel / launch pad / test range with test pilots and engineers getting on with the task of making and testing the space craft.
Some of the other reviews criticise the over use of pictures of the test pilots and ground crew, but this misses the point, actually seeing the space programme evolve through the early chapters to the fully fledged exploration of space in later chapters was totally captivating.
There are tonnes of books out there showing what was happens when we make it in to space but few which shows the people and the assiduous step by step process from those early beginnings to the first moon landing and beyond to the space shuttle and the international space station.
I would defiantly recommend this book, not just to engineers, but to any body interested in the details of how NASA solved the myriad of problems associated with space travel and the people involved. Top class.
