I've read the book, and Kranz definitely says at least once that the phrase "failure is not an option" is a good summary of what the flight controllers believed. Could you perhaps elaborate on what you mean by your comment?
As Kranz lays out in the book (and as indicated in the wiki) "Failure is not an option" was written by the Apollo 13 screenwriters. The original quote was by the FIDO at the time which was adapted for the movie. Kranz has since started using it as it summarizes the idea more succinctly.
I understand. I was asking for an elucidation of the comment that it was "not what the astronauts or flight controllers believed" and is a "poor abbreviation".
