First off, Paul Schneider was silenced twenty years ago. That is a long time to continue development from his point of disclosure. Rather importantly he completely confirms the existence of an extensive underground mining operation as we have also determined. His description makes it far more extensive that i ever imagined.
Do note that he quotes a base set in three cubic miles. That would be its geometric extent and not represent actual volumes of rock removed.
We also talk Dulce. This is likely the first alien base uncovered and integrated into the dark programs. Thus the plausibility of accidentally breaking into the unmapped alien structure.
The numbers that he quotes for rail-cars and helicopters appear excessive and his control of numbers is generally blurred. On the other hand, he is clearly suffering from brain damage and the related PTSD. At the same time, alternate sources for much of this material did not exist.
I have now seen plenty of confirmation and his explanations regarding human alien interaction is now well attested by thousands of reports.
