For the 12th straight year, a number of local groups have teammed up to place flags at Memorial Park.
Each flag has a name, age and location of the victims who died on September 11, 2001. There is also a special display for Nebraskans who were killed.
The flags will remain at Memorial Park until the end of the week.
Students at Lothrop Magnet School in north Omaha came together Wednesday morning to present plaques to the Omaha Police and Fire Departments to honor the first responders who gave their lives while trying to save others 12 years ago.
