"Nothing like the thought bubbles had been seen before the 1994 season", wrote Michael Glickman... "A curving line of circles, increasing in size, ended with a large "head" often incorporating a crescent or moon (see also East Ilsley and Moulsford formations). The Wilsford site featured on the cover of Michael Hesemann's best-selling book, 'A Cosmic Connection', alongside a picture of one of Billy Meier's 'beamships' - both genuine "beyond doubt", according to the author.
