25 Years After 9/11, America Remembers the Lives Lost and the Courage That Followed

September 11, 2026

Twenty-five years after the September 11 terrorist attacks, Americans are once again remembering a day that profoundly changed the nation and the world.

On the morning of September 11, 2001, terrorists hijacked four commercial aircraft. American Airlines Flight 11 struck the North Tower of the World Trade Center in New York at 8:46 a.m., followed by United Airlines Flight 175 striking the South Tower shortly after 9 a.m. American Airlines Flight 77 later hit the Pentagon in Arlington, Virginia. United Airlines Flight 93 crashed near Shanksville, Pennsylvania, after passengers and crew members fought back against the hijackers. (U.S. Department of War)

The attacks killed 2,977 people — 2,753 in New York, 184 at the Pentagon and 40 aboard Flight 93. The victims came from many countries, communities, professions and backgrounds. Hundreds of firefighters, police officers and other emergency personnel were among those killed while responding to the disaster. (911 Memorial)

A Quarter-Century of Remembrance

President Donald Trump proclaimed September 11, 2026, as Patriot Day, continuing the annual national observance established by Congress following the attacks. The proclamation directs U.S. flags at federal facilities to be flown at half-staff in honor of the victims and calls on Americans to remember those who died and recognize the sacrifices of first responders and members of the Armed Forces.

This year's observance carries particular significance. A full quarter-century has now passed since the attacks, meaning a growing generation of Americans was born after September 11, 2001.

That passage of time has placed increasing importance on preserving the history of the attacks and passing the stories of victims, survivors and rescuers to younger generations.

At the National September 11 Memorial in New York, the names of those killed on September 11, along with the six victims of the 1993 World Trade Center bombing, are inscribed around the Memorial's reflecting pools in the footprints of the former Twin Towers. (911 Memorial)

Remembering More Than One Day

The legacy of September 11 also extends to thousands of people who participated in rescue, recovery and cleanup efforts at Ground Zero and other affected locations. Many later developed serious illnesses associated with exposure to hazardous materials in the aftermath of the attacks.

The National September 11 Memorial & Museum's Memorial Glade specifically honors rescue and recovery workers, survivors and community members who became ill or died because of their exposure following 9/11.

The attacks also transformed American aviation security, emergency preparedness, intelligence operations and national security policy and led to years of military operations overseas.

Yet for many families, September 11 remains foremost a deeply personal anniversary — a day to remember parents, children, spouses, relatives, friends and colleagues whose lives were taken without warning.

Remembering Courage and Unity

Alongside the tragedy, September 11 is remembered for extraordinary acts of courage.

Firefighters and police officers entered the World Trade Center towers while thousands were evacuating. Military and civilian personnel helped rescue colleagues from the damaged Pentagon. On Flight 93, passengers and crew members resisted the hijackers before the aircraft crashed in Pennsylvania, preventing it from reaching its intended destination. (HistSecDef Office)

Those stories have become an enduring part of how the nation remembers 9/11.

For Americans who witnessed the events of 2001, the images and emotions remain vivid. For those born afterward, the 25th anniversary carries a different responsibility: learning what happened, understanding its consequences and keeping alive the memories of the people behind the number 2,977.

Twenty-five years later, the central message of September 11 remains simple:

Remember those who were lost. Honor those who responded. Preserve their stories for generations to come.
