Once a quiet field in Shanksville, transformed into somber memorial

Friday marks the 14th anniversary of September 11, 2001, and with it, the crash of United Flight 93, one of four planes that were hijacked. A new memorial was dedicated outside Shanksville, Pennsylvania, to honor those on board who gave their lives to divert the plane from hitting the Capitol. Hari Sreenivasan reports.
