Too often, the UFO phenomenon is dismissed for its supposed exclusive reliance on eyewitness testimony. However, there are numerous examples of UFO encounters that have left tangible traces of their presence in the physical environment, or on the witnesses themselves.
The so-called Cash-Landrum Case of 1980 is a notable example of the latter, having left all three of its witnesses with symptoms of severe radiation poisoning following a late-night encounter with an unidentified object.
It is one case, at least, that cannot possibly be dismissed as a fabrication, a misidentification, or a hallucination, and one that points to a possible connection between the UFO phenomenon and the U.S. government.
