The Office of the Director of National Intelligence has published an unclassified document: Preliminary Assessment on Unidentified Aerial Phenomena.
The assessment, which focuses on UAP reports between 2004 and 2021, does not break any new ground and leaves open all questions related to the origin of the phenomena. However, it does highlight two key points: that the reported phenomena share characteristics such as shape, propulsion and unusual flight characteristics, and also cluster around military installations.
The report is inconclusive and states that UAP probably lack a single explanation.
The report states that the UAP represent a flight risk and states that it does not know the phenomena to be related to technology of global rivals.
“We currently lack data to indicate any UAP are part of a foreign collection program or indicative of a major technological advancement by a potential adversary. We continue to monitor for evidence of such programs given the counter intelligence challenge they would pose, particularly as some UAP have been detected near military facilities or by aircraft carrying the USG’s most advanced sensor systems.“
“UAP sightings also tended to cluster around U.S. training and testing grounds, but we assess that this may result from a collection bias as a result of focused attention, greater numbers of latest-generation sensors operating in those areas, unit expectations, and guidance to report anomalies. And a Handful of UAP Appear to Demonstrate Advanced Technology.”
“In 18 incidents, described in 21 reports, observers reported unusual UAP movement patterns or flight characteristics. Some UAP appeared to remain stationary in winds aloft, move against the wind, maneuver abruptly, or move at considerable speed, without discernable means of propulsion. In a small number of cases, military aircraft systems processed radio frequency (RF) energy associated with UAP sightings. The UAPTF holds a small amount of data that appear to show UAP demonstrating acceleration or a degree of signature management. Additional rigorous analysis are necessary by multiple teams or groups of technical experts to determine the nature and validity of these data. We are conducting further analysis to determine if breakthrough technologies were demonstrated.”
The reports suggests an investment in research and greater collection of data.
