Worst U.S. Firefighting Tragedies

This past Sunday was also the sixth anniversary of the "Father's Day Fire" that occurred in New York City on June 17, 2001. Three firefighters were killed when an explosion rocked a warehouse in Astoria, Queens.

In the last 10 years, one of the two incidents that proved most deadly for firefighters occurred just a few months after the Father's Day Fire. The September 11 terror attacks claimed 343 New York City firefighters.

The Dec. 3, 1999 fire at the Worcester Cold Storage Warehouse in Worcester, MA, claimed the live of six firefighters that were operating inside the structure when conditions deteriorated rapidly.
