"Science and the UFO controversy" and "The OZ Files" columns in the UFOlogist and "UFO Truth" magazines
Both publications are worth your support:
Research, investigations & commentary from Bill Chalker, author of "The OZ Files - the Australian UFO Story" (1996), "Hair of the Alien - DNA and Other Forensic Evidence for Alien Abductions" (2005) and Australian chapter author of the UFO History Group's foundational reference work "UFOs and Government" (2012)
An intriguing article has been just published in the peer reviewed Journal of Astrobiology: "Something Intelligent this Way Comes" which includes the following quote:
The author - Robert Powell, a friend, a co-author with me & others on the book "UFOs and Government" and research director of MUFON. The word UFO doesn't appear in this peer reviewed article, but this is a nice stealthy alternative, seemingly acceptable to current mainstream scientific sensibilities."... as a society we have difficulty dealing with the possibility that intelligent life may reach us first and may have already done so."
