The world has changed dramatically since the terrorist attacks on September 11. 

It's a day many of us will never forget. 

On Wednesday, UTC's ROTC is holding a remembrance walk to honor the nearly 3,000 who died in the attacks in New York and the Pentagon. 

Members, staff and faculty of UTC's ROTC are carrying flags as they walk around Chamberlain Field.

The event started at 6 a.m today and goes until 5 p.m.
