Physics expert Rosie O'Donnell sez...

...I do believe it's the first time in history that fire has melted steel - I do believe that it defies physics for the World Trade Center Building 7, which collapsed in on itself, it is impossible for a building to fall the way it fell without explosives being involved - World Trade Center 7.

One and two got hit by planes, 7 miraculously the first time in history, steel was melted by fire - it is physically impossible," states O'Donnell.

I don't know but to say we don't know and it was imploded in a demolition is beyond ignorant, look at the films get a physics expert here from Yale, from Harvard, pick the school, it defies reason.
