President Barack Obama quietly laid a wreath at the marbled Wall of Names at Shanksville, Pa., marking those who were killed aboard United Flight 93. During the ceremony, a man called out: "Thanks for getting bin Laden!" Thousands of family members and friends of the 40 passengers and crew killed on 9/11 gathered for a second day at the newly dedicated Flight 93 Memorial, the nation's newest national park.
