Silver Spring, Md.-A wallet, a key chain, a belt, a helmet. To most, those everyday objects have no real meaning, but to the families of those killed in the attacks on the World Trade Center, recovered personal items are precious mementos of lost loved ones, and for many, a way to help achieve closure. "WTC 9-11: Stories From The Ruins" profiles the men and women dedicated to recovering these effects and tells the stories of the people to whom they once belonged. "WTC 9-11: Stories From The Ruins" premieres on the Discovery Channel on Sept. 11, from 10-11 p.m. On Sept. 12, 2001, the first truck filled with debris from the World Trade Center rolled onto the Fresh Kills Landfill in Staten Island, bringing the first of almost two million tons of material to the site for examination. The landfill was declared a crime scene, and thousands of detectives, agents, forensic specialists and volunteers poured over every piece of material to piece to gather clues to help solve the case. But after the world knew the names of those responsible for the attacks, the sifting and sorting of debris continued for 10 months, almost two million hours of work, in an effort to return personal belongings to the victims' families. In this special, family members who've received one of the recovery team's bittersweet gifts recount stories of those killed in the attack, while the show travels to Fresh Kills to reveal how the painstaking process to recover the artifacts began. Viewers also get unprecedented access inside Hangar 17 at JFK Airport, where many of the non-personal artifacts are housed.
