When talking about alien related stories, Dulce Papers have it all including greys, reptilians, alien/human hybrids, abductions, cattle mutilations, mind manipulation experiments, cover-ups, murder and underground alien bases.
The story of Dulce is centered on Thomas Costello or Castello in some sources. Dulce Papers talk much about Castello but apparently they are rarely seen, or not seen at all. These papers are allegedly talking about a joint Alien/US Government underground facility found beneath Dulce New Mexico. Included in the papers are black and white illustrations of scenes apparently witnessed by Castello.
Rumors spread that there are 25 images in the papers but only 5 can be found online as the original file is said to be lost. There are many YouTube videos online claiming to show aliens at Dulce Base. While Thomas Castello is the center of this entire story, he is a deep throat himself because no one has ever met him, communicated or interviewed him directly. At least no one can prove to have talk or met him in flesh, it has been always through an intermediary.
It is said that the underground bunker has different sections including the entrance of the UFO, elevator, security and communications, human staff housing, execs and labs, alien housing, genetic experiments and cryogenic storage. It is also revealed that there is an underground shuttle to Los Alamos.
