"Within minutes of the World Trade Center collapse on 9/11/01, emergency personnel and volunteers from around the nation responded to New York's call for help in what is considered by many as the greatest rescue mission ever. When everything could have totally fallen apart, these remarkable people revealed to the world the true meaning of the American Spirit.
This is THEIR story."
(Please type "dead video" if the video is not working so that we can fix it. Thank you!)
and yes again, the 'weakened steel' ... if fire, common office fire (forget the 'jet fuel' hysteria comments ... jet fuel is just kerosene) can weaken structural steel to the point where a building collapses, shouldn't we be taking down every building over ten stories tall in this country? isn't ANY decent sized fire going to bring them down??? the Sears Tower in Chicago is built the same way as the Twin Towers ... why aren't they taking it down if it is this vulnerable?
obvious answer is ... that it isn't vulnerable to this type of fire ...
also 'asymmetrical damage DOES NOT result in symmetrical collapse' ... the tops of the tower above the 'impact zone' should have tipped and gone over ... and in the video you can see the giant tv antenna doing just that ... but then suddenly, this MASSIVE section of the building, approx 20 stories, changes direction (!!??) and falls straight down onto the remaining approx 80 floors and a implosion type collapse occurs at near free fall speed
wake up folks ... just think about it ... you don't have to be an architectural genius to figure this out ...
