Project Grudge succeeded Project Sign in 1949 with an explicitly more skeptical mandate, reflecting Air Force leadership’s preference to de-emphasize UFO reports as a matter of public reassurance.
Approach
Grudge’s 1949 report concluded that UFO reports resulted from mass hysteria, individual misperception, hoaxes, and a small number of genuinely unexplained residual cases, and recommended reducing the priority and resources devoted to investigation. Case officer Edward Ruppelt later described Grudge-era investigation as cursory and predisposed toward dismissive conclusions.
Legacy
Renewed public sighting waves, including the 1952 Washington D.C. Flap, prompted the Air Force to reorganize Grudge into the more resourced Project Blue Book later that year.
