Ten years ago, the September 11 attacks shook the foundations of American life. The acts of 19 terrorists and their nearly 3,000 victims rippled well beyond the World Trade Center in New York City, the Pentagon, and the Pennsylvania field where United Airlines Flight 93 crashed, to change the world itself.

Where were you that day? What has the decade since meant for you? AZPM's special tenth anniversary feature, "Ten Years On: Tucson Remembers 9/11," invites you to share your remembrances, or reflect on the change the past decade has wrought.
