In this photo made on Oct. 28, 2009, Flight 93 Ambassador Bob Musser talks about how many people come to the temporary memorial where Flight 93 crashed in the Sept. 11, 2001 attacks in Shanksville, Pa.. These volunteers, known as Flight 93 Ambassadors, are a group formed by locals who noticed people showing up at the crash site yet having no idea what they were looking at or where the plane went down. More than 130,000 people visit the site every year.
