FILE - In this Sept. 11, 2001, file photo, the twin towers of the World Trade Center burn behind the Empire State Building in New York. The twin towers stood as New York's tallest from 1972 until the terrorist attacks of Sept. 11, 2001, when two planes crashed into the World Trade Center causing the twin 110-story towers to collapse, making the Empire State Building the tallest once again.
