Karli Buhr plans to honor first responders in a special way on September 11. The 11-year-old from Thatcher, Arizona, will take part in a memorial stair climb. Events like this one are held nationwide. They honor emergency workers who risked their lives to help others on September 11, 2001.
That day, terrorists flew two planes into the Twin Towers of the World Trade Center in New York City. Terrified people ran from each of the 110-story skyscrapers. But firefighters, police officers, and other emergency workers ran into the towers. They climbed the stairs to try to save people.
Meanwhile, a group of terrorists flew a third plane into the Pentagon. That’s the U.S. military headquarters in Arlington, Virginia. A fourth plane crashed in a field in Shanksville, Pennsylvania.
Nearly 3,000 people died that day, which is now known as 9/11. That includes more than 400 firefighters, police officers, and paramedics who were killed when the Twin Towers collapsed.
