 Belgian UFO photos

Belgium in UFO Photographs - Volume 1, written by Wim VAN UTRECHT (CAELESTIA,  Belgium) and Vicente-Juan BALLESTER OLMOS (FOTOCAT, Spain), is a scientifically oriented inquiry into all known UFO pictures taken in Belgium between 1950 and 1988. Next to descriptions of UFO sightings and detailed analyses of UFO images, the book has numerous examples of how untrained observers were deceived by common phenomena, and how photographs of dubious origin made their way into UFO history.

The book is a documented history of four decades' worth of UFO incidents that involved witnesses who provided photographic evidence (be that negatives, prints, slides, films, or videotapes) on top of their own testimony. The authors have investigated every event weighing the evidence for real anomalies occurring in our atmosphere.

The foreword has been contributed by James Oberg, one of the world's leading popularizers and interpreters of space exploration. Oberg had a 22-year career as a space engineer in Houston, where he specialized in NASA space shuttle operations for orbital rendezvous. Below are a few excerpts of what Oberg wrote about the first volume of Belgium in UFO Photographs:

Belgium in UFO Photographs - Volume 1

Ballester-Olmos and Van Utrecht, like me, believe that 'IFOs' have lessons to teach 'ufologists' that are crucial to making sense of cases that remain in the 'true UFO' data bases . . . The newfound power of combining GOOD records keeping with Internet tools and search engines can be seen in specific cases discussed by the authors . . . In case after case, the authors apply wide knowledge of geometry, optics, meteorology, human perception, and human cultural context, to illustrate that plausible explanations often are found . . .

The approach shown by Ballester-Olmos and Van Utrecht should serve as an example and as an inspiration to other 'citizen scientists' who have played a crucial role in providing the resources that will allow theorists with more data and wider insight to someday make more sense about what lies behind this mysterious phenomenon.
