I am fascinated by UFO sightings but remain open minded as to whether or not there is an explanation for these sightings.
I am very pleased with this book which has a photograph for each sighting and a relatively short but interesting commentary. The photos which hail from many countries are arranged in chronological groupings and span from the 1870s right up to 2011. One of the first UFO pictures was taken in the 1870s - this surprised me a lot. Of course, the authenticity of the pictures will always be open to debate, but given the production quality of the book I believe the author/publisher would not knowingly include a photograph that was faked. Of course, this does not mean that some of the photos are not well executed hoaxes. On a more positive note, though, assuming the majority of the photographs are not faked the book does make you wonder - is there something out there?
This book is nicely produced and laid out. The photographs are, I believe, reproduced as best as the originals will allow and in many cases they are very clear. A common feature is that in many of the photographs a magnified shot of the UFO is inset into the original shot. The commentary is brief, and, as the title suggests the emphasis is on the visual evidence.
In summary, a good quality and thought provoking book based around photographic evidence suggesting the existence of UFOs. This is an enjoyable book which I think I will revisit again and again. Recommended.
