Summary
On September 11, 2001, the seismic stations grouped around New York City recorded seismic events from the WTC site, two of which occurred immediately prior to the aircraft impacts upon the Twin Towers. Because these seismic events preceded the collisions, it is clear they were not associated with the impacts and must therefore be associated with some other occurrence. None of the authorities charged with the responsibility for the investigation of the events of 9/11 have proposed a source for these seismic events, nor have they given a valid reason for the difference in times between the seismic events and the aircraft impacts. Only by consideration of the evidence of basement explosions before the aircraft impacts, as experienced by William Rodriquez and 36 others, can an explanation be found for the fact that the seismic stations recorded seismic events originating from the WTC sites prior to the aircraft impacts. It seems unlikely that Middle Eastern terrorists could have overcome the WTC security and managed this kind of high-level, technological coordination. Do the facts presented here, simple and few, raise the possibility of inside involvement in 9/11/01, both before and after the attack?
