Have UFO files been released?

Yes. UFO files have been released, including a seventh tranche of White House documents, covered in a report describing live expert analysis of that release [3]. VETTED also reported on the release of a seventh tranche, while NewsNation reviewed newly released Pentagon UFO documents [6][2].

The releases include different kinds of material. One report focuses on a black-triangle UFO described in files as documented by military bases, and another covers newly released reports of orb sightings; those descriptions do not by themselves establish what the objects were [4][5]. The site also lists a collection of White House and congressional correspondence from 1998 about UFO inquiries [7].

The government-file release is described as an ongoing process: documents are to be added to an archive in batches, as agencies review tens of millions of records [1]. The released material does not settle every case; the government says some reports lack enough information to determine what was seen, and the cause of the phenomena in the cases being released remains unknown [1].
