On the morning of September 11, 2001, just 15 minutes after hearing the alarm, the FDNY’s elite Rescue Company 2—Lieutenant Peter Martin and firefighters William Lake, Daniel Libretti, John Napolitano, Lincoln Quappe, Kevin O’Rourke, and Edward Rall—arrived at the unfolding World Trade Center tragedy. All seven were killed when the building collapsed. In all, 2,977 lives were lost that day and hundreds have died from illnesses related to the attack’s aftermath.
