The Central Intelligence Agency has admitted that it was responsible for at least half of reported UFO sightings in the middle of the last century due to its secret, high-altitude reconnaissance flights.
“High altitude testing of the U-2 soon led to an unexpected side effect – a tremendous increase in reports of unidentified flying objects (UFOs),” the 1998 report noted.
In general, the CIA document admitted to being responsible for “more than half” of the UFO sightings, many are left wondering what or who was responsible for the other half of reported sightings.
