UFOs

This book wasn't what I expected. I've read other books about UFOs which always have a (conspiracy) theory about them that they push as fact. This book was different, the author was very articulate and well-researched and didn't push anything beyond eyewitness observations, mostly through interviews and letters. Some ideas of the origin of the phenomena were presented, but never pushed. This is top-notch reporting on the subject, presented clearly. The one thing I found, because it didn't push any answers, just a multitude of mysteries, that the book was more frightening and real than anything I've read.
