The world changed at . American Airlines Flight 11, traveling at roughly 490 mph, crashed into the North Tower of the World Trade Center. It struck between the 93rd and 99th floors.

– In a national address from the Oval Office, Bush declares: “We will make no distinction between the terrorists who committed these acts and those who harbor them.”

We remember those lost, those who survived, and those who rushed to help.

: 2,977 victims were killed across all three sites [5, 8, 20]. Cleanup

Three minutes before impact in the South Tower, United Airlines Flight 175 (another Boston-to-LA Boeing 767, carrying 56 passengers including 5 hijackers) is taken over. The pilots are Captain Victor Saracini and First Officer Michael Horrocks. A passenger, Peter Hanson, calls his father Lee and describes the chaos: “I think we are getting hijacked. They have knives and Mace. Oh my God, they are so cold-blooded.”

: The North Tower collapses 102 minutes after impact [5, 6, 10]. Afternoon and Evening

The fire-weakened outer E ring of the Pentagon collapses, five stories down to the ground. However, structural reinforcements installed after the 1993 World Trade Center bombing prevent the rest of the building from falling.

As passengers break through the cockpit door, the hijackers roll the plane upside down and deliberately crash it into a reclaimed strip mine near Shanksville, Pennsylvania, at 563 mph. The plane explodes on impact, leaving a crater 10 feet deep and 50 feet wide. All 44 people aboard are killed (including 4 hijackers). The intended target—later confirmed by recovered cockpit voice recordings as the U.S. Capitol—is never reached. The 9/11 Commission will later conclude: “The passengers of Flight 93 saved the Capitol.”

– The North Tower collapses after burning for 102 minutes. Debris and dust clouds engulf Lower Manhattan.

The timeline of the September 11, 2001, terrorist attacks captures the events from the first takeoff to the final collapse of the World Trade Center buildings. On that morning, 19 al-Qaeda terrorists hijacked four commercial California-bound airplanes [20, 24].

Understanding the sequence of 9/11 helps us grasp not just the horror of that day, but the heroism—of passengers, first responders, and everyday people. It also shaped modern air travel, surveillance laws, and U.S. foreign policy for decades to come.

American Airlines Flight 77 crashes into the western facade of the Pentagon at 530 mph. The plane penetrates the building’s outer three rings (the outermost “E” ring). The impact kills all 64 people aboard (including 5 hijackers) and 125 military and civilian personnel inside the Pentagon. Dozens of others are severely burned. The fire is so intense that it takes firefighters three days to fully extinguish.
