Overview of 9/11 Attacks

Before we dive into the number of buildings destroyed, let’s take a brief look at the events of 9/11. On September 11, 2001, a group of terrorists hijacked four commercial airplanes and carried out coordinated suicide attacks against the United States. Two of the planes crashed into the Twin Towers of the WTC, while another hit the Pentagon in Virginia. The fourth plane crashed in a field in Pennsylvania after passengers tried to overpower the hijackers.

The attacks claimed the lives of 2,977 people, including 246 on the four planes, 2,606 in the WTC and surrounding areas, and 125 at the Pentagon. It was the deadliest terrorist attack in history and marked a turning point in the United States’ approach to national security.
