9/11 Facts

When the World Trade Center fell on September 11, 2001, a Halifax police dog named Trakr and his handler drove 15 hours from Nova Scotia to help. Buried under 30 feet of unstable rubble, Trakr found Genelle Guzman-McMillan - a Port Authority worker trapped for 27 hours and the last of the 20 live survivors pulled from the debris. Seven years later, a contest chose Trakr as the world's most "clone-worthy" dog. He died before the results arrived. In June 2009, five cloned puppies - Trustt, Solace, Valor, Prodigy, and Deja Vu - were delivered to his handler.

Bretagne, a golden retriever, worked Ground Zero for 10 days after 9/11 as a 2-year-old. She later responded to Hurricanes Katrina, Rita, and Ivan. When she died at 16 in 2016, firefighters lined the sidewalk and saluted her - then carried her out draped in an American flag.

Steve Buscemi was an FDNY firefighter with Engine 55 for four years before he became a movie star. When the World Trade Center fell on 9/11, he went back to his old firehouse. For five days he worked 12-hour shifts digging through the rubble. He declined every interview and photo request the whole time.
