T7 had no basement it was built over an old eddison transformer station. Here the interesting bit, it did have underground access to the port authority building ( wtc 6 I think). So the FBI and CIA possibly were using that building's basement for record keeping and storage. That fema reporter thats on the run posted his videos of being the first people allowed to enter the wtc complex. Port Authority Vaults were 100% cleaned out and the whole middle of the building is just missing just the outside walls left standing and a pile of rubble. Now going out on a limb here but have seen some reports the building had external fire damage prior to the wtc collapse, think a few pics are floating around there. Forget the cash imagine the blackmail.
