Physical Analyses in Ten Cases of Unexplained Aerial Objects with Material Samples

Jacques F. Vallee, 1550 California St. #6L, San Francisco, CA 94109

A survey of ten cases of unexplained aerial phenomena accompanied by material residues shows a broad distribution of natural elements, many of which are metallic in nature. They can be roughly described as belonging in two categories: "light materials" of high conductivity such as aluminum, and "slag-like materials" reminiscent of industrial byproducts. Most of the cases under consideration strive to meet four criteria: 1) the literature gives sufficient ground to support the fact that an unusual aerial phenomenon occurred, 2) the circumstances of the actual recovery of the specimen are reported, 3) there is data to suggest that the specimen is in fact linked to the observed aerial object, and 4) physical analysis has been performed by a competent laboratory of known reliability. In several instances the sample is available for continuing study by independent scientists. In the absence of a firm chain of evidence and of professional field investigation, most cases cannot lead to a definite conclusion about the nature of the phenomena that gave rise to each specimen, but much can be learned from the methodology involved in such analysis. Furthermore, compilation of similar cases on an expanded basis may eventually lead to the discovery of underlying patterns.
