When the first plane crashed into the World Trade Center on September 11, 2001 every network television station switched to live coverage. People held out hope that there was a pilot error, or something wrong with the plane. Not many people thought it was a deliberate action. But when we saw the second plane crash into the building, live on tv, we all knew the United States was under attack.

The footage is very disturbing, but I would encourage you to watch it. We must never forget what happened on September 11, 2001.
