The United States Department of Defence has released three declassified videos of “unexplained aerial phenomena”.
The Pentagon said that it was to “clear up any misconception by the public on whether or not the footage that has been circulated was real”.
The video had already been leaked in 2007 and 2017.
Two were published by the New York Times, while the third was leaked by an organisation c0-founded by former Blink-182 singer, Tom DeLonge.
In a statement, the Pentagon said: “After thorough review, the department has determined that the authorised release of the unclassified video does not reveal sensitive capabilities or systems, and does not impinge on any subsequent investigation of military air space incursions by unidentified aerial phenomena.
“The Department of Defence is releasing 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 far more to the video.
“The aerial phenomena observed in the video remain characterised as ‘unidentified’.”
