Across the nation, many Americans marked the 18th anniversary of Sept. 11, 2001 terror attacks with a moment of silence and memorial services. Although years have passed, Americans are unable to forget the horror, pain, and confusion they experienced when terrorist-piloted planes crashed into the World Trade Center, the Pentagon, and on a field in Pennsylvania.

Nearly 3,000 innocent people were killed that day, including 184 lives that were taken at the Pentagon. Families are still feeling the grief from losing a loved one, while many heroic first responders are still suffering from health-related problems after being exposed to the smoke and dust at ground zero while facing imminent danger.
