Dr. Vallee does not come to conclusions about UFOs or what they may be. However, what his research shows is that reports of such phenomena have been occurring since antiquity. Jacques Vallee, Ph.D. is one of today's most widely respected researchers of unexplained aerial phenomena. He earned a Masters Degree in Astrophysics while living in France and holds a Ph.D. in computer science from Northwestern University. His life experience was the model portrayed by François Truffaut in the Steven Spielberg award winning film, Close Encounters of the Third Kind. He is the author of numerous books, including Passport to Magonia, his seminal work, and Wonders in the Sky: Unexplained Aerial Objects from Antiquity to Modern Times (co-author with Chris Aubeck) (Tarcher/Penguin 2010)
