On September 11, 2001, the world witnessed one of the most devastating terrorist attacks in modern history. At 9:03 a.m., just 17 minutes after the first strike on the North Tower of the World Trade Center, United Airlines Flight 175 crashed into the South Tower. The horrifying moment was broadcast live on television and instantly confirmed to millions of viewers that the United States was under coordinated attack.

The attacks began at 8:46 a.m. when American Airlines Flight 11 hit the North Tower of the World Trade Center. Many initially believed it to be a tragic accident. However, at 9:03 a.m., when United Airlines Flight 175 struck the South Tower, it became tragically clear that these events were deliberate acts of terrorism.

Both towers of the World Trade Center would ultimately collapse, resulting in the loss of thousands of lives and forever changing the global landscape.

The impact of the second plane caused a massive fireball that engulfed the upper floors of the South Tower. The strike was captured on live television, shocking viewers around the world and leaving no doubt that the United States was under attack.

The collision killed everyone on board and trapped countless people inside the building. First responders immediately rushed to the scene, demonstrating incredible bravery in the face of unimaginable danger.

Nearly 3,000 people lost their lives on September 11, 2001. Victims included office workers, airline passengers, firefighters, police officers, and emergency personnel who rushed into the towers to save lives.

The attack remains one of the deadliest days in American history. Each year, memorial ceremonies are held to honor the victims and the courage of those who responded.

Two decades have passed since the 9/11 attacks, yet the memory remains as vivid as ever. The events of that day reshaped U.S. foreign and domestic policy, led to wars overseas, and transformed global security measures.

For many, the footage of the second plane hitting the South Tower remains the defining image of the tragedy—an unforgettable moment that marked a turning point in history.

Twenty years on, it is important not only to remember the tragedy but also to reflect on the resilience shown in its aftermath. The rebuilding of Lower Manhattan, the establishment of the 9/11 Memorial & Museum, and the stories of survival and heroism serve as lasting reminders that even in the darkest times, human strength and unity can prevail.
