No matter if you're just curious about UFOs or a closet ufologist, if you could read one book on the subject of UFOs, this is the book to read. Looking at this subject from the perspective of US national security and airspace violations, as opposed to "little green men," will make you think about UFOs in a different, more serious light. Dolan does an excellent job keeping on subject while making it a brisk read. I can't wait for volume two.
