The US Department of War released a new tranche of UFO and unidentified anomalous phenomena (UAP) records on Friday, 18 September, including film of bright, disc‑shaped objects recorded near Tremonton, Utah, in 1952 and documents relating to a US defence programme that examined speculative concepts such as warp drives, wormholes and cloaking.
The sixth tranche was released under the Presidential Unsealing and Reporting System for UAP Encounters, or PURSUE. The collection includes historical case files, military footage and research documents spanning decades.
