I was working when the first plane hit that September morning. I got home from work in time to see the replay from a single camera. More cameras were deployed when the second plane hit and I remember watching it live.

At that moment, I knew it was not an accident. I knew we were under attack. It was the day many Americans realized there were people out there who did not like us. People who would go out into the streets and cheer when our countrymen died.

I already knew that, but I will never forget that refresher course. I will never forget those who died that day. I will never forget those who chose to fight that day. Those who marched into burning buildings to save people they did not know. Those who charged their hijackers.

I will never forget how my fellow Americans stood up that day.

It is one of the many days that made me proud to be an American.

I will never forget.
