According to MW Cooper, it "contains 16 volumes of documented information collected from the beginning of the United States investigation of Unidentified Flying Objects (UFO's) and Identified Alien Crafts (IAC). The project was funded by CIA confidential funds (non-appropriated) and money from the illicit drug trade. Participation in the illegal drug trade was justified in that it would identify and eliminate the weak elements of our society. The purpose of project GRUDGE was to collect all scientific, technological, medical and intelligence information from UFO/IAC sightings and contacts with alien life forms. This orderly file of collected information has been used to advance the United States Space Program."
It should be noted that Project Grudge replaced Project Sign when the team of Sign had come to the conclusion that UFOs were extraterrestrial vehicles, and this conclusion was deemed inacceptable by the Pentagon. From the very beginning, therefore, Project Grudge had an agenda to debunk and exclude the extraterrestrial hypothesis.
