September 11 Attacks
Terrorists hijacked four commercial airplanes, crashing two into the World Trade Center in New York City, one into the Pentagon, and one into a field in Shanksville, Pennsylvania after passengers fought back. Nearly 3,000 people were killed in the deadliest attack on American soil.
Why It Matters
