The Survey to the top UFO researchers is going the way to become a book.
It will be published --we expect-- as a paperback edition and as an e-book by Amazon.
The title and sub-title of the book, --after discussions about making it attractive to the general public-- will be: "Aliens, Ships, and Hoaxes - The first international survey of the top UFO researchers in the world"
Vicente-Juan Ballester Olmos --UAPSG Member, and dear friend-- sent an updated version of his prestigious UFO FOTOCAT at December 2018.
