"Terror from the sky"
September 11, 2001, started as a routine Tuesday morning for millions of Americans. But at 8:46 a. m., a low-flying jet with more than 90 people aboard crashed into one of the Twin Towers of the World Trade Center, a huge office complex in New York City.

On a typical day, some 50,000 workers filled its offices, and 200,000 visitors from all over the globe flocked to its shops, restaurants, and sky-high observation deck. At 110 stories each, its matching silver skyscrapers were a famous symbol of the nation’s power and prosperity.

A terrorist group called Al Qaeda, led by a man named Osama bin Laden, soon claimed responsibility for the attacks
