Various pieces of aircraft debris were found within the wreckage at the Pentagon. While on fire himself, and escaping from the Navy Command Center, Lt. Kevin Shaeffer observed a chunk of the aircraft's nose cone and the nose landing gear in the service road between rings B and C. Early in the morning on Friday, September 14, Fairfax County Urban Search and Rescue Team members Carlton Burkhammer and Brian Moravitz came across an "intact seat from the plane's cockpit", while paramedics and firefighters located the two black boxes near the punch out hole in the A-E drive, nearly 300 feet (91 m) into the building. The cockpit voice recorder was too badly damaged and charred to retrieve any information, though the flight data recorder yielded useful information. Investigators also found a part of Nawaf al-Hazmi's driver's license in the North Parking Lot rubble pile. Personal effects belonging to victims were also found, and taken to Fort Myer.

Army engineers determined by 17:30 on the first day that no one remained alive in the damaged section of the building. In the days after the crash, news reports emerged that up to 800 people had died. Army troops from Fort Belvoir were the first teams to survey the interior of the crash site and noted the presence of human remains.[
