Excellent news. As of August 2016 the massive work by the UFO History group (Michael Swords, Robert Powell, Clas Svahn, Vicente-Juan Ballester Olmos, Barry Greenwood, Richard Thieme, Jan Aldrich, Steve Purcell and me) "UFOs and Government - A History Inquiry" is available as an e-book through multiple outlets including Amazon.
Vicente-Juan Ballester Olmos
I was very pleased to participate in this book as the author of the Australian chapter. Although I'm biased I highly recommend this excellent book. Thanks to Patrick Huyghe and Anomalist Books.
It is also available through Apple iBooks, Barnes and Noble Nook and Kobo.
It is also available as a laminated hardcover and as a trade paperback.
