In this review, I will delve into the contents of the book and highlight its significance in the field of UFOlogy.


“The UFO Handbook” is a comprehensive guide to investigating UFO sightings, offering a methodical approach to evaluating and reporting these enigmatic phenomena. Hendry, an astronomer and seasoned UFO investigator, presents a wealth of knowledge and experience in the book, which is divided into several key sections:
