Caroline Dries was a student in New York City on Sept. 11, 2001. She started filming the dark smoke coming out of the World Trade Center after hearing an explosion. The horrifying footage she captured would become an iconic piece of documentation for the worst terrorist attack to ever happen on American soil.
On the morning of 9/11, two hijacked planes crashed into the twin towers of the World Trade Center 18 minutes apart from each other. On the same day, another plane hit the Pentagon in Washington, and a fourth crashed in Pennsylvania. The disastrous attack killed 2,763 people, including first responders, and injured nearly 10,000.
