... At a minimum, my investigation suggests that depths up to three miles are feasible, and that conclusion is based on a careful reading of the open scientific, mining and civil engineering literature. At one time I considered greater depths than that as unattainable, but no longer. While I don’t know the limitations of the technology in the clandestine realm, based on everything I have heard over the years, it must surpass the limits found in the open technical literature. It could be that with classified improvements in materials science and mining engineering that bases can be sited many miles beneath the surface of the land or the seafloor. Frankly, I now surmise that we are dealing with a science-fiction-like reality that has been held back from public knowledge.

In that regard, it is clear to me that there are power structures on this planet that closely interface with, and yet remain separate from, the official power establishment of any nation as publicly presented in the mainstream news media. The sum total of all the many years of reading and research I have done, coupled with the myriad conversations I have had with an extremely eclectic selection of individuals, even raises the question as to whether some control structures and agencies for this planet may possibly extend off-planet. But even if that is not the case, we are certainly dealing at the least with trillions of dollars of off-the-books money, very advanced technology, an incredible infrastructure of secrecy, thousands and thousands of people who are in the know but say little or nothing about what they know, all of which revolves around projects of tremendous scope and complexity, carried out over a long period of time, and about which there is almost zero public knowledge.

It is unknown how many secret underground bases there are, but they surely do exist, there is no question of that. In 1987, Lloyd A. Duscha, the then-Deputy Director of Engineering and Construction for the U.S. Army Corps of Engineers, gave a talk at an engineering conference entitled “Underground Facilities for Defense – Experience and Lessons.” In the first paragraph of his talk he stated that:

After World War II, political and economic factors changed the underground construction picture and caused a renewed interest to “think underground.” As a result of this interest, the Corps of Engineers became involved in the design and construction of some very complex and interesting military projects.

A little further on he said:

Although the conference program indicates the topic to be “Underground Facilities for Defense – Experience and Lessons,” I must deviate a little because several of the most interesting facilities that have been designed and constructed by the Corps are classified.

Subsequently Mr. Duscha went into a discussion of the Corps’ involvement in the 1960s in the construction of the large and elaborate NORAD base buried deep beneath Cheyenne Mountain, in Colorado. And then he said:

As stated earlier, there are other projects of similar scope, which I cannot identify, but which included multiple chambers up to 50 feet wide and 100 feet high using the same excavation procedures mentioned for the NORAD facility.

You will not find a franker public admission of the existence of secret, underground bases than that. It carries all the more weight coming from Lloyd Duscha, given his high position in the military-industrial complex.
