Anyone who was in New York City on Sept. 11, 2001, remembers how the ash, paper and dust of the collapsing towers blew across Lower Manhattan. For days afterward, there was that peculiar smell -- of burned paper and chemicals and death. That was the air that filled the lungs of tens of thousands of firefighters, police officers, nurses, paramedics, soldiers and civilian volunteers who toiled for months to uncover the dead. More than nine years later, many of those first responders are dead. Many are sick. Some are dying. Thousands need care for illnesses contracted through their heroism at ground zero.
