Fuk! I feel like I'm back on active duty.
I wonder if there is any USGS graphs/data for lower Manhattan for 9/11 that would show multiple shock forces for all three buildings collapse?
This data could indicate explosives (multiple wave forms with separate peaks and amplitudes) vice the lower rumble of a "collapse" of the towers and Bld. 7. Kind of like sonar signatures for Sub warfare. I am not great at surfing the USGS data. Any seismic Fags?
