What Is the Biggest Attack in American History?

The United States of America has witnessed several attacks in its history, but the biggest one to date is the 9/11 terrorist attacks. On September 11, 2001, a group of terrorists associated with al-Qaeda hijacked four commercial airplanes and carried out suicide attacks against significant Targets in the United States.

The Attack

The attack began at 8:46 am when American Airlines Flight 11 crashed into the North Tower of the World Trade Center in New York City. At that time, most people believed it was a tragic accident until United Airlines Flight 175 hit the South Tower just fifteen minutes later.

Impact on the Nation

These two attacks caused significant damage to both towers, including destroying multiple floors and causing fires that burned for hours. The impact was not only physical but also emotional and psychological. The entire nation was shocked and horrified by these events.

At 9:37 am, American Airlines Flight 77 crashed into the west side of the Pentagon in Arlington, Virginia. This attack caused significant damage to a section of one of the most well-protected buildings in the world.

At 10:03 am, United Airlines Flight 93 crashed into a field near Shanksville, Pennsylvania. It is believed that passengers on board this plane tried to overpower the hijackers before it crashed.


The aftermath of these attacks resulted in over 3,000 deaths and even more injuries. Many people were left homeless or without jobs due to destruction caused by these attacks.

The death toll included not only Americans but also individuals from over ninety other countries who were visiting or working in New York City at that time.

Response from Government

Following these devastating attacks, many emergency responders arrived at Ground Zero to help with rescue operations. The US government declared a national emergency and launched investigations into who was behind the attacks.

The War on Terrorism began as a direct result of these attacks, with the US government seeking to bring those responsible to justice and prevent similar events from happening again.


The 9/11 terrorist attacks were undoubtedly the biggest attack in American history. The impact of these attacks is still felt today, with increased security measures at airports and other public places.

It is a reminder that we must remain vigilant against those who wish to cause harm and destruction, and we must never forget the lives lost on that tragic day.
