It's a day we will never forget but an increasing number of Americans have no memory of September 11th, 2001.
Today school children across the country attended ceremonies to commemorate the 9-11 attacks.
In Omaha, one of the largest was at Kountze Park.
Most of the students who helped construct a pinwheel flag on display at Kountze Park were not even born when the planes struck the Twin Towers or they were simply too young to remember the attack.
While 9-11 carries great national significance we wondered how some of the youngest Americans remembered the events of that day 11-years ago and how much that has shaped their lives.
They work side by side; students, teachers and firefighters all placing pinwheels on the lines drawn on the grass of Kountze Park.
The 9-11 flag is as festive as the anniversary is somber but most of these students don't remember the events.
North High Junior Ian Howell has only vague memories.
Ian Howell says, "Not much, my mom didn't let me go to school that day because she was scared about what was happening."
Those who watched the events unfold live on television will never forget the fear and uncertainty. Nadia Williams feels a close connection to the event even though she was just a toddler at the time of the attack.
Members of her extended family were in harm's way.
Nadia Williams says, "I don't really know what I'm suppose to think because just the fact that it happened and we lost a lot of people, like my family lives in New York so we didn't really know what we were suppose to do."
The ceremony stressed remembering those who died that day in New York, Washington and the field in Pennsylvania.
One speaker compared the attacks on September 11th to Pearl Harbor.
Battalion Chief Tony Lang says, "You learned about it in history and I think that is what they're doing now. It's great that they got together and they think that much of us, the first responders that were there."
After the ceremony the students thanked the first responders for their service.
Classes from three different schools participated in the Kountze Park event.
North Engineering Students laid out the grid for the pinwheels, Lothrop Elementary made them and King Science planned the ceremony.
In Bellevue Tuesday evening, hundreds attended a ceremony at the newly named American Heroes Park.
A part of the World Trade Center was on display. The piece of steel is in the care of the Bennington Fire Department.
Also during the ceremony, nearly 40 people became new citizens
Federal Judge Lyle Strom, who gave them the oath, said citizenship is one of his greatest experiences on the bench. He said it's the only time both sides leave the courtroom happy.
