Diana Walsh Pasulka is the author of the riveting 2019 book American Cosmic. She is a professor of religious studies at the University of North Carolina-Wilmington, surveyed the then-current state of knowledge of UFOs and related phenomena. She is also someone that the USG has consulted about the likely impact of the phenomenon on society.
She has published a follow-up book entitled Encounters: Experiences With Nonhuman Intelligences (Macmillan), which profiles a wide range of people who for various reasons have been drawn into the shadowy and mysterious world of UFOs, and whose testimonies move the phenomenon out of narrowly-drawn scientific categories, and well into the world of the religious and the paranormal. The way she ties the phenomenon of things flying around in the skies back to our earliest history is fascinating.
