Improved instrumental techniques, including isotopic analysis, applicable to the characterization of unusual materials with potential relevance to aerospace forensics The problem of precise characterization, analysis, and eventual identification of unknown materials arises in many fields and takes many forms, depend…

#UFO #Ubatuba #Brazil 1957 #magnesium samples showed roughly 30%deviation from terrestrial #isotope_ratios. Of 12 #UAP samples, 2 were “not playing by our rules.” One alleged sample turned out to be almost entirely high-purity #silicon; extraordinary for any era
