A guidebook for students who enjoy the exploration of new horizons through practical experimentation, and a rewarding read for any enquiring mind. Eleven easily structured experiments thoroughly test Billy Meier’s controversial WCUFO photos finally laying to rest the little model theory. The tests conclusively evince two large craft, one around three and a half meters in diameter and the other around seven meters in diameter. Anyone with an open, skeptical mind who enjoys practical, analytical, and straightforward tests and discovery will gain much from this book. One intention of this book, apart from just coming to grips with these enigmatic photos, is for it to function as a possible guidebook for young scientists and students. This guide can work as a textbook, a supplementary text, extracurricular material, or in any way deemed useful to the reader or student. The eleven practical and scientific experiments it presents could constitute part of a science course for high school or college students. It is also for the curious, and people interested in following a scientific procedure to arrive at certain facts or truths. We suggest students, experimenters, or armchair readers use this book as a scientist conducting any or all of the eleven experiments and analyses in it. Ideally, to successfully perform these experiments, readers should possess, or have available the core competencies explained in the Introduction; but most importantly, to have curiosity and an open, critical, and skeptical mind ready for experimentation and discovery of the facts and truth concerning the WCUFO. The book is also intended to help those with an interest in the Billy Meier case better understand the nature of these WCUFO photographs, and to shed some much-needed understanding of the truth regarding at least some of these famous - and most controversial - UFO photographs.
