Project Sign
Project Sign is a U.S. Air Force program established in the late 1940s to investigate unidentified flying objects (UFOs). It is notable for being one of the earliest organized efforts to analyze UAP sightings and assess their potential implications for national security. The program involved collaboration among military and intelligence personnel and contributed to the broader discourse on UAP phenomena during its time.
