If the government has made contact with extra terrestrial beings it would have to create an intelligence network to cover it up. It only would take one piece of physical evidence to expose the whole extra terrestrial conspiracy. Therefore, the government would have to create policies and procedures to respond to a leak anywhere in the world, 24 hrs a day. This amount of coverage would require extensive cooperation between domestic agencies and international governments. Some researchers believe that this level of secrecy has been used to cover-up extra terrestrial contact. While critics believe that it is impossible for the government to keep even the smallest of secrets-so it would be unable to contain evidence of extra terrestrial contact.

This type of secrecy is possible and can be illustrated by the SR-71 spy plane program. The general public found out about the project 30 years after it had been developed by Lockheed Martin Skunk Works. The SR-71 program required thousand of contractors and military personnel to develop and maintain the program yet there were no substantial leaks to the general public.

The secrecy was maintained by compartmentalizing the information on the secret project. Only a few key individuals had the complete picture of the covert program while the majority of the workers had limited amounts of information given to them on a 'need to know' basis. Individuals who were entrusted with classified information were carefully screened and tested before they attained the required security clearance needed to work on the project. Therefore, it is possible that information on contact with extra terrestrial beings could be compartmentalized; many people working on the project but only a handful knowing the whole story.

Critics believe that it is impossible for the government to keep even the smallest of secrets. They believe that the vast network required to create and maintain this global conspiracy would soon cause its downfall-all it takes is one small leak of evidence. Critics find it hard to believe that the governments of the world can cooperate to keep the biggest discovery of mankind secret while their own internal departments can't cooperate with one another.

The following United States Intelligence agencies would have to cooperate with one another to maintain the extra terrestrials secret:

National Reconnaissance Office (NRO)
Central Intelligence Agency (CIA)
National Security Agency (NSA)
Federal Bureau of Investigations (FBI)
Defense Intelligence Agency (DIA)

The previous list represents only the intelligence agencies in the United States. To maintain a cloak of global secrecy every intelligence agency around the world must cooperate with one another. If the world's intelligence agencies are able to cooperate with one another to keep extra terrestrial contact secret it would be one of mankind's greatest achievements-but an achievement that goes unnoticed by the public.
