it is available for download on the internet or at least it used to be. check some of the sites, like operation clam bake and some freezone links, etc. you may have to search but if you put in enough key words you should eventually run across it. i have it but printed it out and then deleted it. it is long and the author claims to be "correcting" the mistakes ron made such as errors he claims are in the axioms, the factors, etc. all in all kind of a BS book. mostly taken straight from the tech with his own twists as "corrections." and also his opinions of ron and the tech which are just that - opinions. i found it kind of boring and didn't find any of it really useful. i think the pilot did a far better job as he at least came up with an original idea. excalibur is major plagerism from ron's works.
