What caused the Twin Towers to collapse?

Posted at: 2015-04-20 
The fell due to structural wakening in the area of the fire. Once they collapsed in that area the crashing weight caused the rest to fail.

On 9/11 the twin towers had a terrorist attack and two planes flew into the twin towers and I guess the burning of the buildings caused them to collapse after all a plane flew into them

Controlled demolition. The third tower collapsed even though it was not hit.

Islam.......that's it.....evil vile Islam!

Two jet airliners crashing into them.

unfortunately some countries to educate terrorists for a special profit....but this seems to make a hole in a ship....all passengers will drown......today DA-ESH is a sample...

It was a terrorist attack

Oh please, read a history book.
