Pasquale Buzzelli. This 34-year-old Port Authority worker had begun the descent from his office on the 64th floor of the North Tower via Stairwell B and had reached what he believed was the 22nd floor when the building collapsed. (Genelle Guzman-McMillan, a clerk who was with him when the building went down, recalled they were on the 13th floor when everything came apart, so there still remains controversy as to where they were in the building at that critical moment, and thus how far they fell.) Buzzelli was knocked unconscious but came to a few hours later, was discovered atop a high pile of rubble by firemen, and rescued. His right foot was fractured and he had suffered a few scrapes and bruises, but was otherwise unharmed. Guzman-McMillan suffered a crushed right leg and was not pulled from the wreckage until a day after the disaster. Sixteen people in all survived the collapse of the North Tower.
