Commemorations stretch from the attack sites — at New York's World Trade Center, the Pentagon and Shanksville, Pennsylvania — to Alaska and beyond. But a sense of connection is enshrined in a local memorial incorporating steel from the World Trade Center’s destroyed twin towers. As another way of marking the anniversary, many Americans do volunteer work on what Congress has designated both Patriot Day and a National Day of Service and Remembrance. First lady Jill Biden is due to lay a wreath at the 9/11 memorial at the Pentagon. Educators with a total of more than 10,000 students have registered for access to the free “National Day of Learning” program, which will be available through the fall, organizers say.
