Project Grudge
The successor to Project Sign which was launched to effectively denounce the UFO problem. Journalists were encouraged to write articles saying that UFOs didn't exist. The final report said that, despite getting 23% more reports than Project Sign did, all sightings could be dismissed on psychological ground and that any further investigation should be downgraded greatly, which it was. Project Grudge was shut down in 1950.
Project Grudge was the second official United States Air Force program for the investigation of Unidentified Flying Objects (UFOs), active from 1949 to 1951. It succeeded Project Sign and was itself succeeded by Project Blue Book in March 1952.
Background
[edit | edit source]After General Hoyt Vandenberg rejected the conclusion of Project Sign's "Estimate of the Situation" — which had reportedly found UFOs to be likely extraterrestrial — Project Sign was dismantled and replaced at the end of 1948 by Project Grudge, under a reorganized mandate.
Mandate and Approach
[edit | edit source]Project Grudge was widely characterized — by Captain Edward J. Ruppelt and others — as having a debunking mandate: its primary purpose, critics argued, was not to investigate UFOs but to explain them away. Ruppelt described the Grudge era as the "dark ages" of early USAF UFO investigation.
Project Grudge issued its final report in 1949, concluding that:
- All UFO reports were attributable to mass hysteria, misidentification of conventional objects, or psychological causes.
- No evidence existed that UFOs represented foreign technology.
However, the report also acknowledged that approximately 23 percent of cases could not be explained — a figure that created tension with its broader dismissive conclusions.
Replacement by Project Blue Book
[edit | edit source]By the end of 1951, several high-ranking USAF generals — notably General Charles P. Cabell, who had witnessed a UFO personally — were dissatisfied with Project Grudge's performance. They dismantled it and replaced it with Project Blue Book in March 1952, under the leadership of Captain Edward J. Ruppelt.
Legacy
[edit | edit source]Project Grudge established a template of institutional skepticism toward UFO reports that, critics argue, persisted throughout much of Project Blue Book's existence. The debunking approach attributed to Grudge foreshadowed the directives issued following the Robertson Panel in 1953.
