Dayton, Texas (Cash-Landrum incident site)

Unlike traditional archaeological sites, the Cash-Landrum incident location has been studied primarily by UFO researchers and medical investigators rather than archaeologists. The most significant investigation was conducted by the Mutual UFO Network (MUFON), led by researcher John Schuessler, a former NASA engineer who documented the case extensively. MUFON's investigation included medical examinations of all three witnesses, who exhibited symptoms consistent with radiation exposure including hair loss, skin burns, nausea, and eye problems.

Dr. Peter Rank, a radiologist working with MUFON, confirmed that the witnesses' symptoms were consistent with ionizing radiation exposure, though no radioactive traces were found at the site when tested months later. The U.S. Air Force conducted its own investigation and officially denied any involvement, stating they had no aircraft in the area that night. Military records showed no Chinook helicopter flights matching the witnesses' account, leading to the government's successful defense against the federal lawsuit.

What remains genuinely unknown is the source of the witnesses' injuries and the identity of the craft they described. The case stands apart from other UFO reports because of the physical evidence in the form of documented medical symptoms and the multiple credible witnesses. Despite extensive investigation by both civilian researchers and government agencies, no conventional explanation has been accepted by all parties involved.

The site itself shows no physical traces of the alleged encounter, as the incident involved an aerial phenomenon rather than ground contact. However, the detailed witness accounts and medical documentation have made this location significant in UFO research, representing one of the few cases where alleged extraterrestrial contact resulted in measurable physical effects on human witnesses.
