Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The modern interest in UFO sightings started in 1947, the the Kenneth Arnold incident and Roswell. The increasing number of UFO sightings in the United States of America led to the foundation of Project Sign in 1948 - this U.S. Air Force project was the first of three projects which were introduced to investigate reports on unidentified flying objects. Even though the majority of events investigated were classified as identified with a known astronomical, atmospheric or human-caused phenomenon, a small percentage of unidentified flying objects remained to fuel the fantasy and to serve as evidence of the existence of extraterrestrial beings. Learn more about theories and explanations of the origins of unidentified flying objects, both from UFO enthusiasts and various official governmental responses and investigations in the following pages.
