The US Central Intelligence Agency has admitted that half of UFO sightings in the 1950s and 1960s were the country’s U-2 spy planes.
“Reports of unusual activity in the skies in the ’50s? It was us,” the CIA said in a tweet on Monday.
The agency explained that it was testing the spy planes at altitudes of over 60,000 feet. The figure was not believable at that time.
According to the spy agency, the document explaining that scenario was the most widely read document released this year by the CIA from their database.
The U-2 spy plane is flown by the United States Air Force now.
