The newest Pentagon report on UAPs – or Unidentified Aerial Phenomenon – reflects long standing public interest about what’s in our skies. Now, NASA is investigating for themselves.

Should we assume that what we can’t identify is alien visitation? In our regular look at critical thinking, we look at the history of UFO sightings, visit Roswell on the 75th anniversary of the crash, and ask how our desire to believe influences our interpretation of evidence.

Guests:

Paul Hynek – Teacher at Pepperdine University and son of the late astronomer J. Allen Hynek

Roger Launius – Former chief historian for NASA and former Chair of the Division of Space History at the Smithsonian National Air and Space Museum
