NASA's UAP Framework and the 2022 Investigation: Assessing Anomalies, Risks, and Uncertainty

To the point

Unidentified aerial phenomena (UAP) are sky sightings that can’t be identified as aircraft or known natural phenomena; NASA notes the term’s roots in Kenneth Arnold’s 1952 Mt. Rainier sighting, uses a five‑category framework (Airborne clutter, natural atmospheric phenomena, U.S. government or industry programs, foreign adversary systems, and Other), says findings are largely inconclusive but UAP can threaten aviation safety and national security, a study started in October 2022 aims to analyze data and origins with a mid‑2023 report, lawmakers have held hearings, Sean Kirkpatrick says there’s no evidence of aliens and only about 2–5% of reports are truly anomalous, and there have been over 500 reports.
