On September 11, 2001, at approximately 9:38 a.m., hijacked American Airlines flight 77 was intentionally slammed into the outermost "E Ring" of the west face of the Pentagon building in Arlington, VA, in a terrorist attack. One hundred eighty-four innocent people were killed--125 people in the Pentagon, and 59 passengers and crew aboard the airliner (not counting the terrorists involved); scores of people were injured; and a portion of the building was damaged, later requiring demolition and reconstruction.

	Local firefighters are among the first on the  scene to fight the fast-spreading fire and  begin search and rescue operations.
The Engineer Company, Military District of Washington, responded to the attacks within hours.  They flew the Corps flag during their relief operations.

	President Bush's famous quote was inscribed  onto a piece of limestone and was signed by  many construction workers.  (This limestone  was extracted from the same section of the  Indiana rock quarry that provided the limestone used for facing the Pentagon in 1941.)  This inspirational quote was later installed inside the newly-repaired portion of the Pentagon.
