The head of the official inquiry explains his theories on why the World Trade Center Towers collapsed.
"No building could have survived such a blow, expert after expert has said.But things are hardly that simple. No one has authoritatively explained why One World Trade Center remained standing for 1 hour and 40 minutes while Two World Trade Center crashed to the ground just 56 minutes after impact. Another mystery is why smaller, nearby structures remained standing even though fire and steel from the twin towers rained down on them and even ripped huge chunks out of their facades."
