Twenty-five years ago today, on the morning of September 11, 2001, the United States suffered the deadliest terrorist attack in its history.
Nineteen hijackers affiliated with al-Qaeda seized control of four commercial airliners. Two were deliberately flown into the Twin Towers of the World Trade Center in New York City. A third struck the Pentagon in Arlington, Virginia.
The fourth, United Airlines Flight 93, crashed in a field near Shanksville, Pennsylvania, after passengers and crew fought to regain control of the plane.Nearly 3,000 people from more than 90 countries were killed. The victims included office workers, first responders, airline passengers and crew, military personnel, and bystanders.
Thousands more were injured. The collapse of the towers and the ensuing recovery efforts claimed the lives of hundreds of firefighters, police officers, and other emergency workers who ran toward danger.The attacks transformed American life and global affairs. They led to the creation of the Department of Homeland Security, sweeping changes in aviation security, and the launch of military campaigns in Afghanistan and later Iraq as part of what became known as the War on Terror.
They also left a lasting mark on national psyche, civil liberties debates, and international relations.A quarter-century later, the physical scars have largely been rebuilt. The National September 11 Memorial & Museum stands at Ground Zero. The Pentagon has long been repaired. A memorial marks the crash site of Flight 93. Yet the human cost remains. Families still grieve.
First responders and survivors continue to face long-term health effects from exposure to toxins at the sites. Annual ceremonies of reading the names of the dead keep individual lives from fading into abstraction.
On this 25th anniversary, the day is marked by solemn remembrances, moments of silence, and renewed focus on the ordinary people who showed extraordinary courage—those who helped strangers evacuate the towers, the passengers of Flight 93 who prevented a further attack, and the responders who never came home. The events of September 11, 2001, remain a defining moment of the modern era, a reminder of both profound loss and the resilience that followed.
