March 1911. The Triangle Waist Factory, Manhattan. Immigrant workers toil for 14 hours a day. A cigarette is tossed into a bin of fabric scraps. Flames sweep through the factory. In 28 minutes the fire is under control, but 146 people have died. Using eyewitness accounts, court transcripts and other archival material, The Triangle Factory Fire Project paints a brutal picture of a disastrous day in American history.
