After the September 11, 2001 attacks on the World Trade Center, one of the largest American flags damaged during the attacks continued to fly above the resulting wreckage during the clean-up efforts.

Seven years later, that flag, dubbed the National 9/11 Flag, was sewn back together by tornado survivors in Greensburg, Kansas, and has also been stitched by World War II veterans, survivors of the Ft. Hood, Texas rampage, and Martin Luther King Jr.’s family.

In addition, a piece of the flag that Abraham Lincoln was laid on after his assassination was stitched into the fabric of the National 9/11 Flag, making it a living testament to the resilience and compassion of the American people.

To commemorate the 10th anniversary of the 9/11 attacks, the flag is making its way across the US, where local service heroes in all 50 states are stitching the flag back to its original 13-stripe format. Eventually, it will become a part of a permanent collection at the National September 11 Memorial Museum, which is still under construction.
