9/11 was not the first attack on the World Trade Center. The World Trade Center was previously targeted in a terrorist attack on February 26, 1993. A truck bomb was detonated in the underground parking garage, aiming to bring down the North Tower. While the attack killed six people and injured over a thousand, it ultimately failed to achieve its goal of collapsing the towers. This earlier incident highlighted vulnerabilities in U.S. security and foreshadowed the more devastating attacks that would occur on September 11, 2001.

Flight 93’s passengers fought back. On the morning of September 11, 2001, United Airlines Flight 93 was hijacked by terrorists who intended to crash it into a target in Washington, D.C. However, the passengers, aware of the ongoing attacks, banded together and attempted to regain control of the plane. Their courageous actions led to the aircraft crashing into a field in Pennsylvania, preventing further loss of life and likely averting a larger disaster. All 44 people on board perished, but their bravery is commemorated as a symbol of resistance against terrorism.
