Publisher's Synopsis
Estimates indicate that throughout the world, the number of incidents of people seeing unidentified flying objects may exceed several million. Time has proven that seventy percent of all UFO sightings are certain misidentifications of common objects. Another ten percent are attributed to hoaxes, delusions, hysteria or jokes being perpetrated on the observer. The remaining twenty percent are, however, of a real and as yet unexplained nature. This book makes no attempt to prove the impossible. It chronologically lists several hundred of the more than twelve thousand UFO case histories.
