Post-9/11, a Security Blanket For a Wounded Nation

MARTINSBURG, W. Va. -- Within hours of the Sept. 11 terrorist attacks, U.S. flags seemed to be everywhere: car windows, T-shirts, front porches.

The flag took on a larger-than-life symbolism and brought unity to a grieving country.

Ten years later, part of the Sept. 11 story is told through the flag. A flag that once hung near ground zero in New York has been touring the country. Hundreds came to Martinsburg, W.Va., to stitch it together. It's in North Carolina this weekend.

The 30-foot flag flew from a half-destroyed building across from the World Trade Center site in the days after Sept. 11, its stripes torn and tattered by debris. In 2008, it was mended by 58 tornado survivors in Kansas.

Dubbed the National 9/11 Flag, it's been traveling the country ever since -- a journey for the country's most recognizable symbol that has soothed people in a post-9/11 world.
