After terrorists brought down the World Trade Center 20 years ago, an army of construction workers descended upon what was called “Ground Zero” to help police officers and firefighters search for victims and survivors.
It became one of the largest recovery and cleanup operations in the nation’s history, as workers toiled around the clock for nine straight months, facing incomprehensible horror and toxic, smoldering debris. On the day after Americans marked the 20th anniversary of 9/11, union workers marched through Lower Manhattan on Sunday, Sept. 12, to recognized all those who participated in that arduous recovery effort.
