Twin Towers Crash: Remembering the September 11, 2001 Attacks on the World Trade Center

The phrase “Twin Towers crash” commonly refers to the September 11, 2001 terrorist attacks involving the World Trade Center in New York City — one of the deadliest and most significant events in modern history.

On the morning of September 11, 2001, two commercial airplanes hijacked by terrorists were deliberately flown into the North and South Towers of the World Trade Center. The attacks caused catastrophic destruction, ultimately leading to the collapse of both towers and the deaths of nearly 3,000 people.

The first aircraft, American Airlines Flight 11, struck the North Tower at 8:46 a.m. Less than 20 minutes later, United Airlines Flight 175 crashed into the South Tower at 9:03 a.m. Millions of people around the world watched the horrifying events unfold live on television as emergency responders rushed to the scene.

The attacks were carried out by the extremist terrorist organization al-Qaeda and forever changed the United States and the global community.
