It was 11 years ago today that Islamic terrorists humbled our great nation.

Hijacking four U.S. passenger jets, the terrorists from a well-funded group known as al-Qaida crashed two into the World Trade Center towers. Within hours, the towers crumbled to the ground. Another plane crashed into the Pentagon, headquarters of the U.S. Department of Defense. The fourth was meant for the U.S. Capitol Building, home of Congress, but instead it crashed into a field near Shanksville, Pa., after several brave passengers tried to retake it.

In total, nearly 3,000 people were killed.
