Summary
Air Materiel Command general file containing memorandums, correspondence, and forms related to the reporting of information on flying discs and investigations into sightings during 1948. Volume 1 of the 1948 general series, spanning the period during which Project Sign was formally established and active. The standardized reporting forms indicate the AMC had developed formal protocols for collecting UAP observation data by this point. Released via PURSUE Release 1, May 8, 2026.
Significance
Contemporaneous with Project Sign (1948), this file documents the operational reporting infrastructure the Air Materiel Command used to collect flying disc sighting data during the first formal U.S. military UAP investigation. The inclusion of standardized reporting forms indicates institutionalized collection protocols were in place during the Sign era.
