The stone weighs 800 pounds.
When American Airlines Flight 77 crashed into the western side of the Pentagon, Major General James Jackson turned to the Arlington County Fire Department:
"And said, 'What do you want us to do? And from there on, we were in a supporting role for them until they cleaned up the facilities and did what they had to do and turned it back over to the FBI and then back to us."
Now, almost a decade after those events, the Army is presenting the Arlington County Fire Department with an 800-pound block of stone recovered from the wreckage that day. Fire Chief James Schwartz says the stone will be combined with steel recovered from the World Trade Center for a tribute next to Fire Station Number Five.
"We have told our story so many times and to so many people over the last 10 years that I regularly hear my own words repeated back to me as if the speaker had lived them in the way that we did," Schwartz says.
Two other pieces of stone will be presented to the FBI and the New York Fire Department.
