A cultural history of UFOs

Last summer, former military officials testified to Congress about UFOs, and once again the nation’s imagination was ignited. Greg Eghigian, professor of history and bioethics at Pennsylvania State University, joins host Krys Boyd to discuss the history of America’s fascination with UFOs — an obsession that spread globally — and what it all means for our civilization back here on Earth. His book is “After the Flying Saucers Came: A Global History of the UFO Phenomenon.”
