Joseph W. Pfeifer, the first fire chief to arrive at the World Trade Center during the September 11 terrorist attacks, witnessed the exact moment the first hijacked airliner struck the North Tower at 8:46 a.m., according to historical accounts and his recent retrospective interviews. Standing in Manhattan while responding to a suspicion of gas leak, Pfeifer immediately recognized that the impact of American Airlines Flight 11 was an intentional attack rather than an accident, altering emergency response history and claiming the life of his brother, Kevin.
The First Moments at the World Trade Center North Tower
At 8:46 a.m. on September 11, 2001, Pfeifer watched the Boeing 767 slice into the North Tower. Within sixty seconds, he radioed fire dispatch to report that the aircraft appeared to have intentionally targeted the building. Pfeifer and his units established a command post inside the North Tower lobby, which was immediately filled with shattered glass, wounded civilians, and falling debris from above.
Faced with people trapped by thick smoke and intense flames near the upper floors, Pfeifer used the lobby microphone to urge trapped occupants to hold on while rescue teams mounted the stairs. Elevators were completely inoperable, forcing firefighters to carry heavy gear upward against the relentless stream of evacuating office workers. Each firefighting unit consisted of an officer and four firefighters, coordinated under battalion supervision.
The Collapse and Evacuation Order
When the second airplane struck the South Tower, emergency personnel recognized that roughly 20,000 people inside the World Trade Center complex faced a catastrophic crisis. Firefighters pressed upward despite the extreme danger, knowing the scale of the inferno. When the South Tower collapsed, the North Tower lobby was plunged into sudden darkness.
Operating from a small alcove adjacent to the lobby, Pfeifer realized communications and command capabilities were severely compromised. Without knowing immediately that the South Tower had collapsed, he issued a direct radio command: “Command post to all units in Tower 1: evacuate the building!” That order saved numerous lives, though 343 firefighters from the Fire Department of New York (FDNY) ultimately perished during the attacks, including Pfeifer’s brother, Kevin, who had led the firefighters of company Engine 33 up the stairs.
Recovery, Legacy, and Global Lessons in Crisis Management
Pfeifer spent months searching the ruins of Ground Zero for his brother. On February 3, 2002, search teams located Kevin near Stairwell B of the North Tower, dressed in his turnout gear with his Halligan bar nearby. The recovery marked one of the most grueling chapters of the disaster for the FDNY family.
In the years following the attacks, Pfeifer helped establish the FDNY Center for Terrorism and Disaster Preparedness, modernizing inter-agency communication between the FDNY and the New York City Police Department (NYPD) through unified command structures, shared drone feeds, and multi-channel radios. His expertise in crisis management later took him around the world, including to Paris following the 2015 terror attacks, where he consulted with the Paris Fire Brigade (BSPP) and the search-and-intervention brigade (BRI). Those international partnerships later influenced tactical decisions during major urban disasters, including the fire at Notre-Dame Cathedral on April 15, 2019.
As major metropolitan areas continue to face complex modern threats ranging from terrorism to extreme weather events, Pfeifer emphasizes that global preparedness relies on unified civic institutions and shared human resilience. Commemoration ceremonies continue annually in New York, where bells toll to honor the victims of the worst terrorist act in modern history.
