It is to be a missile capable of penetrating 1000 meters of Tuff/hard packed soil such as that found in New Mexico with no operational damage. Missile apogee not to exceed 30,000 feet AGL and impact must not deviate in excess of 50 meters from designated target. The device will carry a 1 megaton nuclear warhead.
R= REDLIGHT : is the project to test fly recovered alien craft. It is conducted at AREA 51 (DREAMLAND) in Nevada. It was aided when the aliens gave us craft and helped us fly them. The initial project was somewhat successful in that we flew a recovered craft but it blew up in the air and the pilots were killed. The project was suspended at that time until the aliens agreed to help us.
P = PLATO : is the project responsible for Diplomatic relations with the aliens. This project secured a formal treaty (illegal under the Constitution) with the aliens. The terms were that the aliens would give us technology. In return we agreed to keep their presence on earth a secret, not to interfere in any way with their actions, and to allow them to abduct humans and animals. The aliens agreed to furnish MJ-12 with a list of abductees on a periodic basis.
O= OPERATION MAJORITY is the name of the operation responsible for every aspect, project, and consequence of alien presence on earth.
