here are some witness acounts:
Alan Wallace -- firefighter with safety crew at Pentagon's heliport
We have had a commercial carrier crash into the west side of the Pentagon at the heliport, Washington Boulevard side. The crew is OK. The airplane was a 757 Boeing or a 320 Airbus.
Albert Hemphill -- from inside the Naval Annex
Immediately, the large silver cylinder of an aircraft appeared in my window, coming over my right shoulder as I faced the Westside of the Pentagon directly towards the heliport. The aircraft, looking to be either a 757 or Airbus, seemed to come directly over the annex
James S. Robbins -- Robbins, a national-security analyst and 'nationalreviewonline' contributor, watched from his 6th story office window in Arlington
The Pentagon is about a mile and half distant in the center of the tableau. I was looking directly at it when the aircraft struck. The sight of the 757 diving in at an unrecoverable angle is frozen in my memory, ...
Tim Timmerman -- from 16th floor apartment near National Airport
It was a Boeing 757, American Airlines, no question.
Mike Dobbs -- observed from upper level of outer ring of Pentagon
... looking out the window when he saw an American Airlines 737 twin-engine airliner strike the building.
Terry Morin -- watched from 5th wing of BMDO offices at the old Navy Annex
The plane had a silver body with red and blue stripes down the fuselage. I believed at the time that it belonged to American Airlines, but I couldn't be sure. It looked like a 737 and I so reported to authorities.
Jim Sutherland -- from his car
... saw ... a white 737 twin-engine plane with multicolored trim fly 50 feet over I-395 in a straight line, striking the side of the Pentagon.
Noel Sepulveda --
... saw a commercial airliner coming from the direction of Henderson Hall the Marine Corps headquarters.
Madelyn Zakhem --
... she heard what she thought was a jet fighter directly overhead. It wasn't. It was an airliner coming straight up Columbia Pike at tree-top level. It was huge! It was silver. It was low -- unbelievable! I could see the cockpit.
Joel Sucherman --
Do you know how many engines? - I did not see the engines, I saw the body and the tail; it was a silver jet with the markings along the windows that spoke to me as an American Airlines jet, it was not a commercial, excuse me, a business jet, it was not a Lear jet, ... it was a bigger plane than that.
Dave Winslow -- Winslow is an AP reporter
I saw the tail of a large airliner ... It ploughed right into the Pentagon.
Steve Anderson -- from 19th floor office in USA TODAY building in Arlington
Then it dawned on me what was about to happen. I watched in horror as the plane flew at treetop level, banked slightly to the left, drug it's wing along the ground and slammed into the west wall of the Pentagon exploding into a giant orange fireball. Then black smoke. Then white smoke.
Jeff and Deb Anlauf -- from 14th floor of Sheraton Hotel, 1.6 miles from explosion
Suddenly I saw this plane right outside my window. You felt like you could touch it; it was that close. It was just incredible. Then it shot straight across from where we are and flew right into the Pentagon. It was just this huge fireball that crashed into the wall (of the Pentagon).
Gary Bauer -- in car just past exit on 395
We looked out the front of our windows to try to see the plane, and it wasn't until a few seconds later that we realized the jet was coming up behind us on that major highway. And it veered to the right into the Pentagon.
Mickey Bell -- near trailer in construction zone outside Pentagon
The jet came in from the south and banked left as it entered the building, narrowly missing the Singleton Electric trailer and the on-site foreman, Mickey Bell. Bell had just left the trailer when he heard a loud noise.
Sean Boger -- from heliport control tower
I just looked up and I saw the big nose and the wings of the aircraft coming right at us and I just watched it hit the building. It exploded. I fell to the ground and covered my head. I could actually hear the metal going through the building.
