FDNY remembers firefighters lost on 'Black Sunday'

Thursday marks 15 years since what the FDNY remembers as Black Sunday.
On Jan. 23, 2005, there were two fires--one in the Bronx and one in Brooklyn. Those fires killed four firefighters: Lieutenants Curtis Meyran, John Bellew and Joseph Dibernardo and firefighter Richard Sclafani.
The FDNY remembered their sacrifices on Thursday.
