In Mission 117 we explore the real case of demonic possession behind William Peter Blatty's horror masterpiece, The Exorcist. Author and researcher Thomas B. Allen obtained a copy of the priest's diary that was kept during the 1949 exorcism of a boy dubbed "Robbie Doe" that reads like a horror novel. Allen used that diary to write his book: Possessed. We discuss what happened, how it differs from the famous movie, and what happened to Robbie Doe after his exorcisms. We also apologize for the poor audio quality on this mission--the Mother Ship must have hit a solar storm that interfered with the transmission. Don't miss UFOs over Denver in the news and Dr. Dreck's own possession!
