The keyword phrase "september 11th explained for kids" functions as a noun phrase, serving as a subject or title. It refers to the historical events of September 11, 2001, a day when a series of coordinated terrorist attacks were carried out against the United States. On that morning, a group of men hijacked four commercial airplanes with the intention of using them as weapons to strike significant American landmarks.
Two of the hijacked airplanes were deliberately flown into the twin towers of the World Trade Center in New York City, causing both buildings to collapse. A third plane struck the Pentagon, the headquarters of the U.S. Department of Defense, in Arlington, Virginia. The fourth plane, believed to be targeting another location in Washington, D.C., crashed into a field in Shanksville, Pennsylvania, after passengers and crew members fought back against the hijackers. These attacks were orchestrated by the terrorist group al-Qaeda.
The events resulted in the deaths of nearly 3,000 people, including civilians, first responders, and military personnel. In response, the United States launched the "War on Terror," leading to significant changes in national security and international relations. The day is now remembered annually as Patriot Day to honor the victims and recognize the heroism of the first responders and ordinary citizens who risked their lives to help others.
