In the full book whose PDF link is mentioned in a comment below he dedicates the book to general Curtis lemays of a rather famous general most people familiar would know and another general whose name I forgotten now I'm not looking at the book and says how they helped him proceed with this work which obviously means this work was highly sanctioned by those high up in the military from day one. Secondly the aftermath or addendum is included in the pdf version of the book that I linked and it begins around page 120 again I'm not looking at the book so I can't tell you exactly but he immediately starts out in the beginning of the aftermath talking about how he was working for a high security project for an aerospace firm around 1967 and 1968 so clearly this man known as Chan Thomas had a high security clearance was highly connected with the military officials and this might explain why he mentions at the end of the book things like artificial gravity and natural magnetic propulsion and it's interesting that of course those pages were not released in the CIA freedom of information act revision that was released.
