Project Sign is a government agency that was established in the late 1940s to investigate unidentified aerial phenomena (UAP) and UFO sightings. It is recognized for its role in the early efforts of the U.S. government to assess and understand the implications of UAP, contributing to the discourse on national security and aerial defense.
