For the first time, Pentagon officially released clips that showed “unidentified” aerial phenomena via their Freedom of Information Act (FOIA) document library.

On Monday, the U.S. Department of Defense has authorized the release of three unclassified Navy videos, one taken in November 2004 and the other two in January 2015, which have been circulating in the public domain after unauthorized releases in 2007 and 2017.

The military officials said the U.S. Navy previously acknowledged that these videos circulating in the public domain were indeed Navy videos.

“After a thorough review, the department has determined that the authorized release of these unclassified videos does not reveal any sensitive capabilities or systems, and does not impinge on any subsequent investigations of military air space incursions by unidentified aerial phenomena,” the DoDo message states.

In a statement Monday, the Pentagon said it is releasing the videos in order to clear up any misconceptions by the public on whether or not the footage that has been circulating was real, or whether or not there is more to the videos. The aerial phenomena observed in the videos remain characterized as “unidentified.”

CNN previously reported that the clips, released between December 2017 and March 2018 by To The Stars Academy of Arts & Sciences, appear to show fast-moving, oblong objects captured by advanced infrared sensors.

In footage from 2004, sensors lock on a target as it flies before it accelerates out of the left side of the frame, too quickly for the sensors to relocate it.
