The most devastating attack on U.S. soil occurred 16 years ago. Almost 3,000 people were killed and more than 6,000 injured when multiple commercial airliners crashed into New York's iconic World Trade Center Twin Towers, the Pentagon and a field in Somerset County, Pennsylvania.

Below are a few before and after pictures. Although some may be disturbing to view, we believe this is an important part of remembering the largest terrorist attack in history.
