events, including United Airlines Flight 175 hitting the South Tower, the debris and "jumpers" falling from the upper floors, and obstructed communications. When the South Tower began to collapse, he took shelter with Battalion 1 Chief Joseph W. Pfeifer and the remaining firefighters, using his camera's floodlight to help them gather the wounded, lost, and deceased as they evacuated the North Tower. He followed the firefighters as they headed north and tried to establish another command post. Meanwhile, Gédéon filmed Benetatos (by now, the only firefighter left in the firehouse) taking calls from the other departments, but eventually took to the streets out of worry for Jules. He walked for some time, filming people's reactions and the damage done by flying debris, and managed to film the impact of Flight 175 into the South Tower. Realizing that he could not get any closer to the WTC, he returned to the firehouse, where he filmed the arrival of various off-duty firefighters. He caught the arrival of retired Battalion 1 Chief Larry Byrnes, but was unable to follow him and Benetatos as they left for the WTC. Gédéon resumed filming the people's reactions as the South Tower collapsed before returning to the firehouse and joining a trio of off-duty firefighters as they headed out to the disaster area. Unable to follow the firefighters to the North Tower, he remained in the area and filmed his surroundings. When the North Tower collapsed, the Naudets fled with the rest of the people still in the area. Jules and Chief Pfeifer took shelter between two cars before returning to the WTC to assess the situation; less than a block away, Gédéon helped an FBI agent carry a civilian who had been overcome by the dust before making his way to a deli to recuperate. Worrying for Jules, he attempted to return to the WTC's ruins, but was turned away by police patrols. He then returned to the firehouse and filmed the returning firefighters' reactions to the attacks. Meanwhile, Jules returned with Chief Pfeifer's group and had an emotional reunion with his brother. The Naudets' video footage became some of the most comprehensive on-site coverage of the 9/11 attacks in New York. Their film was one of only two sources of video footage of Flight 11 striking the World Trade Center, the other being a video shot by Pavel Hlava (an immigrant worker from the Czech
