According to the analytical company “To The Stars – Academy of Arts & Science”, which has published the footage, this record was made in 2015. The UFO appeared at a distance of about 8 km from the aircraft of observation and was not immediately seen by the tracking system. Eventually, they got it.
The video features the original reactions of US fighter pilots.
As reported by Ruposters, in December 2017, this is the first video published publicly by the Pentagon of what they consider to be a UFO.
