Conspiracy theories on 9/11 dealt a blow

 An interesting story today about the report on why a  building on the World Trade Center site collapsed on the afternoon of 9/11. Conspiracy theorists, noting that the CIA had offices in the building, have contended that it was brought down by explosives. But the report says it was fire caused by the World Trade Center collapse that caused the building to fall, despite the fact that such a collapse is rare.
