Majority
According to the late Bill Cooper, Operation Majority is the name of the operation responsible for every aspect, project, and consequence of alien presence on earth.
Many UFOlogists, however, doubt whether the name Majority (instead of Majestic) has ever been used.
A source, related to the release of the Serpo material, claims that both names have been used, that Majority was the original name, but that Majestic started being used, too, after the project was mistakenly called so in one document.
