New Show Alert: Tale of Two Buildings

The terrorist attacks of September 11, 2001 resulted in the swift and total collapse of the Twin Towers. But the Pentagon, which suffered the same kind of blow, largely withstood it. World Trade Center Building 7 collapsed only hours later, even though it had not been directly targeted. What were the unique forces inside each building that determined whether it stood or crumbled, and how? The world’s leading forensic engineers have spent years analyzing the structural consequences of the attacks, and this hour will take viewers deep inside their investigations to explain why the results were so drastically different for each building.
