Undicisettembre: The next question is inevitably about how WTC7 collapsed. As you probably know, conspiracy theorists believe it was demolished with explosives and that the people in the streets didn't expect the collapse. I guess you can rule out this crazy idea once and for all, right?
Lenny Curcio: I can personally rule this out. From the time I arrived until the time I departed the scene on 9/11/01, I was working in front of and in the vicinity due west of 7 WTC. At the time of the WTC 7 collapse, the only “people in the streets” were emergency personnel within an established frozen zone. So, not only did we expect WTC 7 to collapse, we also watched it collapse and had to run for cover. There were no signs whatsoever of explosives or an explosion at that time. The final sounds were of a twisting metal structure (Whining) and then the sound of rubble free falling with earth shattering shock waves.
