Scott and Ramsey put out a new a version in 2015. I just bought it because I don't know about the Aztec event. I have every book put out about the Roswell event and have been there and gone through their 'museum" about their event. I have a copy of their city newspaper put out the day after it happened. This Aztec event happened about eight months after the Roswell one.
imho, the Ramsey book is top flight. They were exhaustive over 10-20 years in their research efforts. They tracked down all manner of folks who had personal experiences with that situation.
The number of data points and correlations they tracked down was impressive, to me.
I hope you enjoy it.
Thanks for your kind reply.
