Most of us remember exactly where we were when we heard about or saw those hijacked planes fly into the Twin Towers in New York back in 2001.
At the Fort Wayne and Allen County Police and Firefighter Memorial on Wells Street just north of downtown, people honored the 412 first responders who sacrificed their lives to help save others that day.
A bagpiper and drummer played as people planted small American flags to honor those brave men and women.
Since the ground is so hard right now, most of the flags were already staked in the grass so they wouldn't break.
Organizers asked folks to pull one out, take a moment, then plant it in the same space.
"We want to make sure that people don't forget this. This is a tragic thing that happened and a lot of kids never were around when this happened. We want their parents, we want the seniors to be able to tell their kids, grandkids what this was all about. We never want to lose the fact that people gave their lives for their fellow human beings, and we don't ever want to forget that," says Jerry Vandeveer from the Police and Firefighter Memorial.
Hundreds of flags were available for people to plant in honor of the first responders or the nearly 3000 civilians who died that awful day.
