Timeline beyond October following the September 11 attacks

• Afternoon: Deputy Mayor Anthony P. Coles meets with the two firefighter union leaders, Fire Capt. Peter L. Gorman, president of the Uniformed Fire Officers Association and Kevin E. Gallagher, president of the Uniformed Firefighters Association, at New York City Hall to discuss the firefighters' unhappiness with the October 31 decision.

• Approximately 10:30 a.m. EST Emotions spill over into violence at a two-hour protest by several hundred to a thousand firefighters near City Hall, beginning at West and Chambers Streets, to protest Giuliani's October 31st ruling to reduce the number of firefighters permitted at the World Trade Center site from 64 to 25. After firefighter Mike Heffernan, brother of John Heffernan, retired fire captain Bill Butler, father of Tommy Butler, and Kevin E. Gallagher, the president of the Uniformed Firefighters Association, speak, the assembled protesters push aside a barricade and begin walking south down West Street. At the next barricade the police move in, punches are thrown, and firefighters handcuffed. Both sides shout for understanding, and the conflict quickly subsides.

Kennedy International Airport, which caused massive air turbulence. As a precaution, the Empire State Building and UN headquarters are evacuated.
