According to Wikipedia:
The National Program Office (NPO) was an office of the United States Government, established to ensure continuity of government in the event of a national disaster. The NPO was established by a secret executive order (National Security Decision Directive 55) signed on 14 September 1982 by President Ronald Reagan during the Cold War in preparation for a nuclear war, presumably with the Soviet Union.
The NPO plan was classified Top Secret, codeword Pegasus. It was also referred to as Project 908 (also known as “Nine Naught Eight”).
The only oversight was by a Project Pegasus committee chaired by then-Vice President George Herbert Walker Bush. The committee included The Chairman of the Joint Chiefs of Staff (or his deputy), FBI Director William H. Webster, Attorney General Edwin Meese III and other top cabinet officials.
The action officer for the project was Marine Lieutenant Colonel Oliver North, who then worked at the National Security Council under retired Marine Lieutenant Colonel Robert McFarlane.

According to the FBI’s response letter, there MAY have be additional records, which I requested. However, in June of 2015, I was informed that if there were additional records, they were destroyed on 9/27/2009. Yet, another example, of lost history.
