This July 2024 supplement from the All-domain Anomaly Resolution Office (AARO) was released in full on 02/06/2025. It adds historical context to Oak Ridge National Laboratory's analysis of a magnesium alloy specimen that has been publicly alleged to come from a crashed extraterrestrial vehicle in 1947. AARO agrees with ORNL that the specimen's magnesium and lead isotopes show a terrestrial origin. It also agrees that the specimen cannot work as a terahertz waveguide. AARO assesses that it is likely a product of mid-20th century research on magnesium alloys.
