Providing an academic lens through which to view the huge interest and hysteria surrounding unidentified flying objects since pilot Kenneth A. Arnold witnessed what he called "flying disks or saucers" while cruising past Mt. Rainier on June 24,1947, a new book titled "After the Flying Saucers Came: A Global History of the UFO Phenomenon" has just been released from Oxford University Press.

Author Greg Eghigian is a professor of history and bioethics at Penn State University who spent nearly a decade delving into the subject of UFOs for this project, which was based on exhaustive archival research, interviews, and newspaper reports swirling around these mysterious aerial sightings.
