Over the years, the museum has collected some 22,000 personal artifacts to help tell the stories of those who died and those lucky to survive. Many of those personal effects were plucked from the ruins of what was once the Twin Towers. Other items were donated by survivors or by the families of those who perished. (AP Photo/Robert Bumsted)
