1. The Twin Towers and WTC 7 were the only steel-framed high-rise buildings ever to come down without explosives or incendiaries.
2. The Twin Towers, each of which had 287 steel columns, were brought down solely by a combination of airplane strikes and jet-fuel fires.
3. WTC 7 was not even hit by a plane, so it was the first steel-framed high-rise to be brought down solely by ordinary building fires.
4. These World Trade Center buildings also came down in free fall – the Twin Towers in virtual free fall, WTC 7 in absolute free fall – for over two seconds.
5. Although the collapses of the WTC buildings were not aided by explosives, the collapses imitated the kinds of implosions that can be induced only by demolition companies.
6. In the case of WTC 7, the structure came down symmetrically (straight down, with an almost perfectly horizontal roofline), which meant that all 82 of the steel support columns had to fall simultaneously, although the building’s fires had a very asymmetrical pattern.
7. The South Tower’s upper 30-floor block changed its angular momentum in midair.
8. This 30 floor block then disintegrated in midair.
9. With regard to the North Tower, some of its steel columns were ejected out horizontally for at least 500 feet.
10. The fires in the debris from the WTC buildings could not be extinguished for many months.
11. Although the WTC fires, based on ordinary building fires, could not have produced temperatures above 1,800℉, the fires inexplicably melted metals with much higher melting points, such as iron (2,800℉) and even molybdenum (4,753℉).
