Huge, I and everybody here is glad you did get your ass away from there before the buildings collapsed. It never occured to me, and prolly most other average americans that those buildings actually would fall. After they withstood the impact of the planes and continued to stand, I figured it was just a matter of evacuating. When the first tower started to crumble I was looking at live footage and I honestly thought they were doing some kind of ariel dump of water (or whatever they use) to try and douse the fire. I was stunned when I realized the building was caving in on itself.
