For many Americans, the images of the 9/11 terrorist attacks on New York City and Washington, D.C, will be forever engrained in their memory. The photos taken of the attacks and the events after them are some of the most iconic images in American history.

Multiple newspapers, online media outlets and magazines printed the images of what happened on Sept. 11, 2001, and on the 14th anniversary of the attacks, these images remain a solemn reminder of one of America’s worst memories. People standing in the windows of the World Trade Center buildings; smoke and debris filling the skyline of Manhattan; firefighters carrying victims from the ashes; former United States President George W. Bush’s reaction when one of his staff members told him of the attacks: These are the just some of the images captured that day 14 years ago. These are the photos of the moments some people remember witnessing with their own eyes.

In the early morning of Sept. 11, 2001, hijackers flew plans into the World Trade Center in New York City and the Pentagon in Arlington, Virginia near the United States capital of Washington, D.C. A third plane crashed into a field in Shanksville, Pennsylvania. It is thought that the plane was intended to crash into either the White House or the Capitol in Washington, D.C. New York City’s tallest skyscraper along with the National September 11 Memorial & Museum were built on the site of the former World Trade Center buildings that were destroyed in the attack.

The attacks resulted in almost 3,000 deaths, making it the worst attack on American soil since the Japanese attack on Pearl Harbor which thrust the United States into World War II. Each year memorial events are planned to commemorate the attacks and the victims who died as a result.
