Military and civilian personnel running up and down the hallways yelling for people to get out and be able to save lives. About 2,600 people working in the Pentagon near the impact site. The fact that alot of people were able to survive this, shows that the Pentagon was built well. Because there were tunnels built under the Pentagon, the fire department was able to go through the tunnels and put the fire out and be able to save a couple of people here and there. Large groups of military and emergency room doctors were waiting for survivors to be brought out of the building. Parts of the airplane were thrown on the perimeter of the building and evidence flags were put on the different parts. The FBI and detectives were walking around conducting their investigation. The military was also waiting outside with body bags to pick up those who didnt make it.
