A great adventure story, but beyond the courage of the Astronauts and the intense devotion of NASA controllers, (as literature,) it is of interest only to those with special knowledge, in the field. I found it heavy going when the authors focused on the technical aspects of the mechanical failure. And there is alot of this from beginning to end.There have been books which are centered on my area of expertise. I found them fascinating throughout. Many of my friends were bored.
