Bill Chalker is one of the worlds most respected Ufologists, author, lecturer and field investigator. In this episode he discusses the recent incursion of UAP's that were shot down over the US, his ongoing work with Jerome Clark and the UFO Encyclopaedia series, the release of Tony Healy and Paul Croper's new book The Yowie Files. We also explore the notion of paranormal aspects involved in these anomalous cases. Be warned at 40 minutes we encounter a feed back anomaly that does not affect the guest narration and so we continued the interview.
