BACKGROUND FACTS

The more information you have, the better you can support your argument.

BUILDING THE WORLD TRADE CENTER
The twin towers opened in 1972 after two years of construction.
Thirteen square blocks were razed to house the WTC complex.
Each floor of the twin towers comprised about 50,000 square feet.
The combined weight of the towers was more than 1.5 million tons. Each tower was built to safely sway about three feet during strong windstorms.
WTC 1 was the world’s tallest building until Chicago’s Sears Tower was completed in 1973.
200,000 tons of steel were used in the construction of the WTC complex.
The WTC complex contained about 43,000 windows and 200 elevators.
About 50,000 people worked in the towers, and more than 200,000 people moved through the towers each day.


PENTAGON SPECS
The Pentagon has a floor space of 3,705,793 square feet and contains 7,754 windows and 17 miles of corridor.
Each of the Pentagon’s outer walls is 921 feet long.
The building was constructed out of reinforced concrete made from 380,000 tons of sand dredged from the Potomac River and is supported by 41,492 concrete piles. The designers’ ingenuity not only created a building that complemented the architectural style of the nation’s capital, but also saved enough steel to build an entire battleship.


ABOUT THE 9/11 CONSPIRACY
A Google search of "9/11 conspiracy" turns up 6 million hits. (The famed "JFK conspiracy" brings 52,000.)
More than 1/3 of the American public suspects that federal officials assisted in the 9/11 terrorist attacks or took no action to stop them so the United States could go to war in the Middle East, according to a 2006 Scripps Howard/Ohio University poll
