Encounters with UFOs have reportedly left Americans suffering from radiation burns, brain and nervous system damage, and even unaccounted for pregnancy," according to a massive database of U.S. government reports recently made public through a Freedom of Information Act (FOIA) request. The database of documents includes more than 1,500 pages of UFO-related material from the Advanced Aerospace Threat Identification Program (AATIP) " a secretive U.S Department of Defense program that ran from 2007 to 2012. Despite never being classified as secret or top secret, the AATIP only became known to the public in 2017, when former program director Luis Elizondo resigned from the Pentagon and released several now-infamous videos of an unidentified aircraft. The U.S. outpost of the British Tabloid The Sun filed a FOIA request for any and all documents related to the program. The U.S. Defense Intelligence Agency (DIA) honored the request by releasing more 1,574 pages of material. One standout document from the collection is a report titled Anomalous Acute and Subacute Field Effects on Human and Biological Tissues, dated March 2010. The report describes alleged injuries to "human observers by anomalous advanced aerospace systems," some of which may be a "threat to United States interests." The report describes 42 cases from medical files and 300 "unpublished" cases where humans sustained injuries after alleged encounters with "anomalous vehicles," which include UFOs.
