Reports of flying saucers and encounters with aliens have been a part of popular culture since the end of World War II. Explanations for their rise and spread have ranged from extra-terrestrial reconnaissance to mass hysteria. Often overlooked, however, is the fact that stories about and responses to the UFO phenomenon have changed over time. How do we account for these changes? And what clues might they provide in helping to explain the enduring fascination with UFOs and alien contact?
Greg Eghigian is Associate Professor of Modern History at Penn State University (USA) and the NASA and American Historical Association Fellow in Aerospace History. He is presently writing a book on the global history of the UFO and alien contact phenomenon.
