From CBS News:
The Pentagon on Friday released a new batch of documents and images related to UFOs, also known as unidentified anomalous phenomena or UAP, including a military pilot’s recollection of a huge, strange triangle that blocked out the stars over Afghanistan in 2002.
The 41 new files, posted on the Pentagon’s UFO website, include a mix of documents, images and videos. The records come from the Pentagon, FBI, CIA, State Department and Executive Office of the President, with the oldest being from 1950 and the most recent being from this year.
