A special group of America's top scientists were organized and a program under the name Project Sign was created in December of 1947 to study the phenomenon. The whole nasty business was contained within the shroud of secrecy. Project Sign evolved into Project Grudge in December of 1948. A low level collection and disinformation project named Blue Book was formed under Grudge. 16 volumes were to come out of Grudge including the controversial "Grudge 13" which I and Bill English saw, read, and revealed to the public. "Blue Teams" were put together to recover the crashed disks and dead or alive aliens. The Blue Teams were later to evolve into Alpha Teams under Project Pounce. During these early years the United States Air Force and the CIA exercised complete control over the Alien Secret. In fact the CIA was formed by Presidential Executive Order first as the Central Intelligence Group for the express purpose of dealing with the alien presence. Later the National Security Act (NSA) was established to oversee the intelligence community and especially the alien endeavor. A series of National Security Council memos and Executive Orders removed the CIA from the sole task of gathering foreign intelligence and slowly but thoroughly "legalized" direct action in the form of covert activities at home and abroad.
