This is, of course, a classic document in UFO research lore. While Dr. Hynek's involvement in Project Blue Book convinced many he was a mere spokesmodel for the perceived government-sponsored Not To Worry campaign, this book at least appears to be more open to the possibilities. The author, certainly one of the most widely recognized experts in the field, calls into question the Air Force's eagerness to jump to conclusions of "natural causes" and rational explanations for many hard to explain cases and events. Several such cases are re-examined in the light of other reports. Reading this with the Project Blue Book Report available side-by-side makes for some very interesting comparisons.

I had the good fortune to hear Dr. Hynek talk about this book and his related adventures during a college speaking tour in 1978, the year after this book was published. As a speaker, he made the possibilities sound even more compelling than this book might indicate.

It is a useful reference book for the ufologist or other persons interested in the phenomenon and in the history and evolution of UFO related research. ( )
