Pentagon's UFO Secret Files Confirm Bizarre Effects Of Sightings On Humans: Report

People may experience biological effects upon seeing unidentified flying objects (UFO), according to reports released by the United States government.

Research by the U.S. Department of Defense's Defense Intelligence Agency (DIA) revealed that UFO sightings may cause humans to experience burns, heart problems and sleep disturbances, The Sun reported, citing documents that the DIA provided to the outlet.

People may also experience other effects such as "apparent abduction" and "unaccounted for pregnancy," as per the documents released following a request filed under the U.S. Freedom of Information Act.

The injuries were often related to electromagnetic radiation and linked to "energy-related propulsion systems," one of the reports claimed.

Such objects may be a "threat to United States interests," the document warned.

Humans allegedly sustained injuries from "exposures to anomalous vehicles," especially airborne and when in close proximity.

Around 42 cases from medical files and 300 similar "unpublished" cases where humans were injured following "anomalous" encounters were included in the report.

“Anomalous behavior” is categorized under an Acquisition Threat Support report, with “AN3” being used for encounters with “ghosts, yetis, spirits and other mythical/legendary entities,” while seeing a UFO with aliens onboard would be classified “CE3.”

Poltergeists, crop circles, spontaneous human combustion, alien abductions and other paranormal events were also reportedly categorized.

The DIA released 1,574 pages worth of documents related to its Advanced Aviation Threat Identification Program (AATIP), a secretive initiative between 2007 and 2012 that studied UFOs.

"Some portions" of the documents "must be withheld in part" due to privacy and confidentiality concerns, according to the DIA.

However, the agency noted that it "has not withheld any reasonably segregable non-exempt portions of the records."

Studies into technologies such as invisibility cloaks and mind-controlled reports were also part of the released documents.

Other documents contained studies into communicating with alien civilizations and plans for deep space exploration and colonization.

The DIA’s decision to release the papers came after a new office to investigate UFOs, the Anomaly Surveillance Resolution Office, was established in November.

It will reportedly investigate whether or not craft that have buzzed the U.S. military were unknown technology from Russia and China or something more alien.
