Thanks Bakes, moar on RAND corp. ( Bill Cooper knew )
In 1959 the Rand Corporation hosted a Deep Underground Construction Symposium. In the symposium report, machines are pictured and described which could bore a tunnel 45 feet in diameter at the rate of 5 feet per hour in 1959. It also displays pictures of huge tunnels and under- ground vaults containing what appear to be complex facilities and possibly even cities. It appears that the previous five years of all-out underground construction had made significant progress by that time.
The secret White House underground-construction fund was set up in 1957 by President Eisenhower. The funding was obtained from Congress under the guise of "construction and maintenance of secret sites where the President could be taken in case of military attack: Presidential Emergency Sites." The sites are literally holes in the ground, deep enough to withstand a nuclear blast, and are outfitted with state-of-the-art communications equipment. To date there are more than 75 sites spread around the country which were built using money from this fund. The Atomic Energy Com- mission has built at least an additional 22 underground sites. See the chapter on Mt. Weather.The location and everything to do with these sites were and are con- sidered and treated as Top Secret. The money was and is in control of the Military Office of the White House, and was and is laundered through so circuitous a web that even the most knowledgeable spy or accountant cannot follow it. ''
